Representative Deng Ganchun: Guarding the "oil bottle" on the dining table

Representative Deng Ganchun: Guarding the "oil bottle" on the dining table
    Ma Aiping March 6, 2024 14:42

Rapeseed, as the largest oil crop in China, is a solid backing to protect the "oil bottle" on the table of the people. At present, the efficiency of rapeseed planting is low, and the price of rapeseed oil fluctuates greatly. Oil and fat enterprises have low profits and high operational risks in processing rapeseed oil, so it is difficult to play the role of bringing agriculture and benefiting farmers.

Therefore, I suggest strengthening the support for rapeseed oil industry, giving full play to regional functional advantages and improving the self-sufficiency rate of edible oil in China.

First, increase subsidies for rapeseed production. It is suggested that the state should introduce the corresponding planting subsidy policy, improve the income guarantee mechanism of farmers planting oil, increase farmers’ planting income and improve farmers’ enthusiasm for rapeseed production.

The second is to support the processing of rapeseed producing areas. It is suggested that the state arrange special funds every year to subsidize the purchase and local processing of rapeseed; ensure a certain proportion of rapeseed oil in the oil reserve, and include complete sets of equipment such as drying and processing of high-quality rapeseed in the national agricultural machinery subsidy scope.

The third is to persist in storing oil in technology and storing oil in the ground. It is suggested that the state should increase investment in research and development, subsidize the mechanized production of rapeseed and encourage large growers to carry out mechanized production. Further improve the farmland rotation fallow system, increase investment in high-standard farmland construction, transform hillock land and abandoned land with poor natural conditions, and expand rape planting area.

Recall Lexus in China

Wanche. com expert Zeng Jian

Engaged in automobile maintenance for many years, with rich theoretical knowledge and practical maintenance experience. He also has a deep understanding of vehicle insurance, loss claims and vehicle service procedures.

    

case

Recently, Toyota Motor (China) Investment Co., Ltd. submitted a recall report to the General Administration of Quality Supervision, Inspection and Quarantine, and recalled some imported Lexus)LS series vehicles from July 19, 2010. According to statistics, there are 5,791 vehicles involved in Chinese mainland.

The reason for the defect is that the strength of the spring is reduced due to the tiny foreign matter mixed in the material of the intake and exhaust valves of the engine, which may cause damage. In this case, the engine will produce abnormal noise and cause poor work. In the worst case, the engine may stop working while driving, which is a potential safety hazard.

    

Expert diagnosis

The function of the valve spring mainly includes the following aspects: (1) to ensure that the intake and exhaust valves automatically return to close and seal; (2) Ensure the seating pressure between the valve and the valve seat; (3) Absorb the inertia force generated by the transmission parts during the opening and closing of the valve, so as to prevent various transmission parts from separating from each other and damage the normal operation of the valve train.

The fatigue life of valve spring mainly depends on working stress, material strength, surface quality, internal quality and manufacturing quality. Automobile valve spring belongs to cylindrical compression coil spring. Under the action of axial force, the shear stress on any cross section of the spring is the largest in the inner diameter of the spring and the smallest in the outer diameter. Therefore, the source of fracture failure and crack caused by design and material strength is often inside the spring.

Because the valve spring has been under the action of alternating stress, if there is a quality problem, the valve spring will have abnormal sound at first, and the acceleration performance of the car will decrease in serious cases, accompanied by difficulties in starting and poor working of individual cylinders.

When the valve spring breaks, the noise of the engine will increase, and in serious cases, the valve will not fully return, which will cause the piston to collide with the intake and exhaust valves, bend the valve stem, damage the piston, and even cause the cylinder head or cylinder block to be scrapped. At the same time, the engine will suddenly shut down, which will easily lead to serious traffic accidents.

    

Expert reminder

How to diagnose valve spring fracture? Whether the valve spring is broken can be seen by disassembling the valve chamber cover. When the engine speed changes, the valve spring will make obvious irregular noise; In static state, you can pry the spring with tools to check it, or you can slide the spring with tools. If the sound is different from other springs and hoarse, it means that the spring is cracked or broken and should be replaced in time.

What should I do when I find that the valve spring is broken? If several springs break at the same time on the way, which has affected the normal running of the vehicle, the driver must stop the engine in time. If there are no accessories or you can’t contact the 4S shop for the time being, you can find a professional maintenance person to remove the broken spring, face the flat parts at both ends, and then install it on the valve stem in the original way. This can temporarily ensure the normal operation of the engine, but the valve spring must be replaced in time after arriving at the 4S shop or the place where the 4S shop can be contacted.

 

  Tips

valve spring

The valve spring is a cylindrical spiral spring and belongs to the valve train of the engine. The function of the valve train is to open and close the intake and exhaust valves regularly according to the needs of the working process of each cylinder of the engine, so that the fresh combustible mixture can enter the cylinder in time and the exhaust gas can be discharged from the cylinder in time.

Pure battery life within 200,000? Revealing the test drive of KIA EV5

Before the start of this test drive, let me ask you a question: What are the core requirements for 150,000-200,000 pure electric vehicles? My answer is to have a good endurance performance, and it would be better if we could add some bright comfort configuration bonus.

picture

Today’s test drive is the car with the longest cruising range of CLTC within 200,000.

A quick look at the advantages and disadvantages of KIA EV5;

Advantages:

1. 720 (long battery life version) is the pure electric vehicle with the longest CLTC cruising range within 200,000.

2, high comfort configuration, unique design

3, kinetic energy recovery can be adjusted in multiple gears, and can also be set to automatic.

4, square box shape, high originality

5. The backrest of the rear seat has a wide adjustment range, and it can be leveled with the trunk to form a big bed.

Insufficient:

1. Due to the shape of the square box, the wind noise is a bit loud.

2. The interior materials have a strong sense of plastic.

exterior

KIA EV5′ s body line style is hard, which makes me more curious: the official standard has the longest battery life of 200,000, is it really resistant to hitting? This point will be answered for you later.

picture

In addition, the front and rear light groups are skillfully integrated into the body lines, which is more coordinated. It is commendable that the styling of the EV5 is highly original. Although many domestic products are both hard-core styling styles, they will always find the shadows of some other cars, but they will not be on the EV5 at all.

picture

interior decoration

Just now, the price of 150,000-200,000 was mentioned, and users also hope that the vehicle can provide good comfort on the premise of sufficient battery life. Generally speaking, the comfort configuration of KIA EV5 is very high. Today, our test drive configuration is the wave version (the official guide price is 225,800 yuan, except this configuration version, the bare car price of other configuration terminals is within 200,000 yuan), the ventilation and heating of the main and passenger seats are equipped, and the steering wheel heating is not missing.

picture

picture

The central control screen is designed as a triple screen. If you don’t observe it carefully, you may mistake it for a double screen. The air-conditioning settings are independently displayed on a display screen, so that adjusting the air-conditioning during driving will not interfere with the display of other information.

picture

The main driver and the co-driver are connected, and the way to connect is that the co-driver seat is extended to the left, which shortens the distance between them, so I won’t say much about the application scenarios. In short, I will vigorously respond to the family planning policy.

picture

On the disadvantage of the front row, that is, the plastic feeling of the materials is slightly strong, but it is not that kind of stiff plastic, and the surface feels elastic.

picture

The comfort configuration in the back row is very rich, with a refrigerator, a table board and a big bed, which is quite "small ideal".

picturepicturepicture

In addition, the angle of the rear seat adjustment is very wide, making it easy to find a comfortable sitting position. There is a hanger behind the headrest of the front seat, which is suitable for people who need to wear formal clothes every day.

picturepicture

Dynamic performance

In terms of power, KIA EV5 is equipped with the first 160kW single motor by default, and some configurations can be equipped with a four-wheel drive system. There is an extra 70kW motor at the rear axle, which is just the test drive model (CLTC cruising range is 630km after the option).

picture

From the subjective acceleration feeling, the EV5 dual-motor model has abundant power level, but it will not have the violent feeling of domestic dual-motor models within 4 seconds. The throttle adjustment is very delicate, no graininess, and very heel-to-heel.

picture

kinetic energy recovery systemsNeed to mention more, its kinetic energy recovery can be adjusted by using the paddle behind the steering wheel, with a total of five gears adjustable. Setting the strongest gear is equivalent to using the single pedal mode, while the lightest gear can almost match the sliding texture of the fuel car.

picture

From the perspective of chassis adjustment and positioning, it is slightly comfortable and the action is crisp and neat, but it may be because the 19-inch wheel hub is bundled with the four-wheel drive system, and the tire is thinner than the 18-inch wheel hub model, so the feedback of fine vibration is more, but it is not disturbing.

picture

The sound insulation performance is limited by the square box modeling style, and the wind noise is obvious at high speed, and there is still room for improvement, even if the front row adopts double layers.Laminated glass.

Power consumption performance, please look forward to it.

Because the itinerary of this activity is relatively free, Xiaobian decided to squeeze out some time to test the power consumption performance of EV5. As for the result, at present, it can only be revealed that there is no reverse virtual standard, but the calculated endurance achievement rate is excellent. Stay tuned!

Please don’t forget these watchmen of "Beautiful China" during the Spring Festival.

  Editor’s note: No matter the ends of the earth or the ends of the earth, at this moment, we are all celebrating the festival. Open the curtains in the morning to see the blue sky and white clouds, look up at the stars at night, and enjoy the beautiful scenery in tourism and leisure — — Nowadays, people’s life is getting richer and richer, and after the demand for material products is met, fresh air, clear water and clean environment are increasingly becoming necessities of life. The Spring Festival, in which thousands of families are smiling, cannot be separated from the unremitting efforts of Qian Qian’s thousands of ecological watchers.

  Monitor of Northeast Tiger and Leopard National Park, Working Group for Strengthening Supervision of Air Pollution Prevention and Control in Autumn and Winter, and Chief Forecaster of Central Meteorological Observatory … … On the eve of the Spring Festival, our reporter approached the front-line workers to understand their working conditions and listen to their New Year’s wishes. Please don’t forget these watchmen of "Beautiful China" when you enjoy the fresh air and the green mountains.

  "Well-off society is not comprehensive, and the quality of ecological environment is very important." Happiness is a struggle, towards the goal of "development of production, affluent life and good ecology", let’s roll up our sleeves and work hard together!

  Protect the common homeland of the Northeast Tiger and Leopard and mankind.

  Deep in the mountains and forests, it’s freezing. Many people stay at home, but Guo Wenliang dives into the mountains.

  Guo Wenliang is the monitor of Suiyang Bureau of Northeast Tiger and Leopard National Park Administration. It is located in Laoyeling, the remaining vein of Changbai Mountain, with dense forests and good ecology. In order to keep an eye on the movements of the tigers and leopards in Northeast China, the Administration has set up more than 400 far-infrared cameras in the forest. Guo Wenliang became the "guardian" of these cameras.

  Guo Wenliang and his assistant Zhang Zejun’s mission in this trip is to set up several new far-infrared cameras and check whether the monitoring equipment along the way is working normally.

  The mountain road is rugged and the snow is thick, so the road up the mountain is not easy. "You see, this string of smaller footprints is silly roe deer, and that string of larger footprints belongs to wild boar … …” Guo Wenliang pointed to a string of footprints in the snow and told reporters.

  All the way into the forest, we stopped at a fork in the road, and Guo Wenliang took out a camera painted in camouflage from his bag. "You see, there are many footprints on both sides of this intersection, and they are clear and coherent, indicating that it is an animal feeding channel. Set up one here! " Guo Wenliang said, "The data of such cameras are gathered together, which provides rich information for scientific research and protection."

  For these "clairvoyance" in the forest, Guo Wenliang didn’t spend less time. Every year in May and October, he will go up the mountain to change the battery and get the data card for the camera. In July, he will clean up the vines and shrubs that block the camera lens. "More than 400 cameras are all well maintained, and it will take more than one month. Walk more than 20 kilometers every day. " Guo Wenliang said with a smile that he spends less time with the camera than with his family in a year.

  Needless to say, you will encounter some dangers in your work. Guo Wenliang once "brushed past" the Northeast Leopard, but now I think about it, I’m still dying.

  Guo Wenliang has been working as a monitor for five years, and he feels that this is a valuable career more and more. "Seeing that the Woods are getting denser and denser, there are more and more wild animals, and there is a sense of accomplishment in my heart."

  In recent years, the ecological environment of the forest farm has been greatly improved after the natural forest was stopped cutting. "The restoration of forest vegetation and the continuous improvement of the food chain have provided the necessary foundation for the survival and reproduction of the Northeast Tiger and Leopard." Guo Wenliang said that at present, Suiyang Bureau has monitored 10 wild Amur tigers and 18 wild Amur leopards from different individuals through far-infrared cameras.

  Win the battle of defending the blue sky, and do it bit by bit.

  Recently, the reporter went to Shenze County, Shijiazhuang City, Hebei Province to carry out supervision following the autumn and winter air pollution prevention and control strengthening supervision working group. In order to defend the blue sky, the Ministry of Ecology and Environment organized and carried out intensive supervision in key areas. There are three people in this working group, drawn from the environmental monitoring teams in Inner Mongolia, Jilin and Guangdong provinces.

  "Do not say hello to local governments and enterprises in advance, and directly enter the enterprise supervision." Zhou Quan, deputy head of the Dalat Banner Environmental Monitoring Brigade in Ordos City, Inner Mongolia, said. He is the leader of the working group. The night before, he has listed the inspection list of seven companies in advance.

  A large local plastic company is equipped with online monitoring equipment, and the working group is particularly alert. "Open the front cover of the equipment and the back cover." Zhang Wenjun, deputy head of the Environmental Monitoring Brigade of Shuangyang District, Changchun City, Jilin Province and a member of the working group, said.

  While carefully checking the internal wiring and displaying data, Zhang Wenjun asked the environmental monitoring third-party staff in detail. Suddenly, his eyebrows locked: "Where is the spare battery?"

  "This … … No … … There is no spare battery. " The staff prevaricated.

  "If there is a power outage, who will bear the responsibility for the lack of monitoring data?" In the face of Zhang Wenjun’s query, the third-party staff and business owners repeatedly said that they would set up a reform and improve the equipment as soon as possible.

  What if you find out the problem? Zhou Quan said that according to the requirements of the Ministry of Ecology and Environment, law enforcement should be strict and "one size fits all" should be avoided. They will enhance their service awareness and take the initiative to make suggestions for enterprises. "The suggestions will suit the right medicine and have strong operability."

  During the inspection, Zhang Wenjun wore a mask all the time. Bronchitis caused mild pneumonia, but he kept working despite his illness. Busy with supervision during the day and infusion at night. Zhang Wenjun said that in recent years, grass-roots environmental protection work has been arduous, and law enforcement personnel have overcome many difficulties. The progress of defending the blue sky is done bit by bit.

  Each round of inspections lasted for 15 days, and the rounds of seamless docking inspections pushed the blue sky defense war in key areas deeper.

  Do a good job in weather forecast and service with craftsman spirit

  At 6: 30 in the morning, before it was clear, He Lifu, the chief forecaster of the Central Meteorological Observatory, had arrived at the consultation room and sat in front of the computer to start a day of intense work. Study the weather situation, judge the future trend, and release the forecast and early warning information … …

  At 8 o’clock in the morning, he began to preside over the national weather forecast video conference every day. It was not until about 8: 30 that he Lifu had time to catch his breath, have breakfast, and then put himself into a new round of forecasting.

  "This is still a routine case. If you encounter major disastrous weather, you will get to the station at four or five in the morning, and the latest warning information will be released before half past six. If you encounter a super typhoon, you will be encrypted for many times in one day. It is common to stay in the consultation room until 10: 30 in the evening and turn around for three or four days. " He Lifu said.

  As the chief forecaster, the body needs to bear high-intensity work, and the psychological pressure resistance is also very strong. For example, when the first snow in Beijing will fall is a difficult problem that makes forecasters anxious. He Lifu said that when the temperature difference is 0.5 degrees Celsius, the snow will fall into rain; Because of the terrain, it may snow all around Beijing, but there is no snow in Beijing. "It’s really hard to report."

  He Lifu has been working in the Central Meteorological Observatory for 34 years. Although he has been under great pressure, he is more and more confident in making predictions. He said: "Limited by the existing technical conditions, we can’t make a particularly accurate forecast of some weather conditions, but over the years, I have really seen great progress in China’s meteorological cause."

  On New Year’s Eve, he Lifu was on duty. In this regard, he smiled and said that he was used to it. "This is not the first time I am on duty on holidays, and certainly it will not be the last time. I have long been used to it. To tell the truth, I feel very embarrassed that I can’t accompany my family on New Year’s Eve. " He Lifu said, "But this is the responsibility of meteorologists. Meteorology concerns thousands of households and all walks of life. Since you have chosen this career, you should stand well in this post. As the chief forecaster, we must polish our predictions with the spirit of artisans to help everyone live a peaceful year. "

Only 4,545 vehicles were delivered in February, and Xpeng Motors was seriously left behind.

On March 1st, Xpeng Motors released the February 2024 delivery data. Data show that in February 2024, a total of 4,545 new cars were delivered, down 24% year-on-year and 45% quarter-on-quarter, of which 1,448 were delivered. In January and February this year, Xpeng Motors delivered a total of 12,795 vehicles, compared with 11,228 vehicles in the same period last year, an increase of 14%.

Previously, in February, Tucki offered limited-time discounts for the 2023 and 2024 models, and adjusted the price of P7i several times, and recently lowered the price of Pengyi Performance Edition by 50,000 yuan to 289,900 yuan. However, these price reduction strategies seem to have failed to significantly increase the sales of G6 and G9.

There are six models currently on sale in Xpeng Motors, including three models, Tucki G6 and Tucki G9, two cars and a Tucki X9. Tucki X9 delivered 1,448 vehicles in February this year, and delivered nearly 4,000 vehicles in February, continuously leading the market of pure electric and pure electric three-row vehicles. With the production capacity climbing after the Spring Festival and the solution of individual supply chain bottlenecks, the production capacity of Tucki X9 will be greatly improved and the delivery will be accelerated from March.

On February 29th, Xpeng Motors pushed the unlimited XNGP intelligent assisted driving function to users with intelligent driving experience, which is no longer restricted to cities and routes, and can be used nationwide. In addition, the monthly active user penetration rate of XNGP Urban Smart Drive reached 83% in February, ranking first in the industry in terms of active user scale, user experience and mileage penetration rate.

During the period of Spring Festival travel rush, the mileage of Tucki car owners using the smart driving function showed explosive growth.

Xpeng Motors’s sales target this year is 280,000 vehicles. In 2023, Xpeng Motors will deliver a total of 141,600 vehicles, with a target completion rate of just over 70%. At the beginning of this year, Xpeng Motors sold 12,795 vehicles in the first two months. To achieve the 24-year sales target, it will sell nearly 27,000 vehicles in the remaining ten months. Despite the influence of Spring Festival holiday and product line adjustment in the first two months, the sales performance of each company is very average. However, judging from the current market performance of Tucki, the situation it faces is very severe. If there is no obvious improvement in sales volume, there is a great chance that this year’s goal will not be achieved.

Now the wild Siberian tiger and leopard in Changbai Mountain area of Jilin Province have been photographed by the footprint camera.

  Changchun, Changchun, December 18 (Reporter Liu Yuanyuan) According to the Voice of China, "Chaoguang News" reported that the footprints of wild Amur tigers and Amur leopards have been discovered in Changbai Mountain area of Jilin Province recently, and a far-infrared monitoring camera even successfully photographed the tiger.

  According to reports, these Siberian tigers and leopards were found in the south of Laoyeling branch of Changbai Mountain in Jilin Province, belonging to two forest farms in Yanbian Korean Autonomous Prefecture. In Xinkai Forest Farm, at 6: 19 pm on December 10th, three photos of tigers were taken, one full-length and two half-length.

  As you can see from the photo, a huge and strong tiger is bowing its head in the snow at night. Experts confirmed that this is an adult wild Siberian tiger. In another forest farm, on December 13th and 14th, there were traces of animals walking and lying on their nests. The animal footprint on the scene is 24 cm long and 18 cm wide, and the length of the nest on the snow is about 1.9 meters. Experts initially determined that this may be a young Siberian tiger or an adult Siberian leopard.

  It is reported that the two forest areas where the discovery site is located are adjacent to two existing national nature reserves in Jilin Province and Heilongjiang Province respectively. Experts say that this is a potential settlement where the expanded breeding population of the Northeast Tiger is looking for a new home, and it is also a key ecological corridor for the Northeast Tiger from Russia to spread to the hinterland of Changbai Mountain along the border between Jilin and Heilongjiang provinces. Therefore, it is in a very important position in the habitat optimization and integration of Amur tiger in Changbai Mountain area of China. Since 2012, there have been many incidents in which female Siberian tiger dung, Siberian tiger footprints and Siberian tigers and leopards attacked cattle, sheep, horses and other livestock. It can be said that the frequent appearance of the Northeast Tiger reflects that the ecological protection in Changbai Mountain has been fruitful since the establishment of Jilin Province for 20 years, and various wild animal populations have been restored, which has provided a strong guarantee for the habitat of the Northeast Tiger and the Northeast Leopard, the first-class protected animals in the country.
