Starting from "Core", test drive Changan Yidong 1.4T Blue Whale Edition.

  [car home Original Test Drive] Looking back a year ago, when the second generation of Changan (|) was officially listed, the stunning appearance made you stunned. I have to say that such an exaggerated and bold design really conforms to the public’s aesthetics, and Changan has made its own style. After a year, Yi Dong Blue Whale Edition came to us again. Although it didn’t surprise us in appearance this time, it quietly changed inside.

Home of the car

  Changan Yidong Blue Whale Edition’s 1.4T engine this time comes from Changan Blue Whale NE power platform, and it has more backbone in the face of competing products. First of all, let’s talk about Changan Blue Whale NE power platform, which is positioned as a medium and small displacement engine. Under the effect of modular concept, it can be compatible with engines with displacement between 1.0L and 1.8L. If necessary, it can also be equipped with front-end technologies such as 48V, PHEV and ethanol fuel, and it also meets the increasingly stringent national VI emission standards.

  The 1.4T engine of Changan Yidong Blue Whale Edition has a slight improvement in parameters compared with its own 1.5T(156 HP /225 Nm), and has certain advantages compared with competing products, even better than the engine book data of some joint venture brands. In terms of transmission, it is equipped with a 7-speed wet dual-clutch gearbox.

  The book data of the engine is excellent. What is the actual performance? Theoretically, the maximum torque of 260N?m starts to break out at 1500rpm, and the low torque should be good, but the engine is more willing to pull the speed above 2000rpm, and it is the stage of its force after intuitively feeling 2000rpm. Earlier torque burst can make up for the lack of low torque of small-displacement engines and create a lighter driving experience. At the same time, the accelerator pedal is light and sensitive at the beginning, and it is easy to follow cars on urban roads, and basically the second half of the accelerator is not needed.

  This 7-speed wet dual-clutch gearbox has good ride comfort during daily driving, and there is basically nothing wrong with daily driving except a little setback in frequent switching between the first and second gears. Although the power connection of the dual-clutch gearbox is not as smooth as that of the AT gearbox at the beginning, according to the performance of most dual-clutches in the market at present, the gearbox mounted on Yidong is indeed slower than the common dual-clutch gearbox.

Changan Automobile Yidong 2019 1.4T Automatic Blue Whale Edition

  At the intersection of traffic lights, the green light lights up to release the brake, and the power connection of the gearbox is a little slow. At this time, you have to give a foot of oil, and it will start slowly and leisurely. If the throttle is given too much, it will run forward again. Especially when turning around, frequently switching between D and R gears, the gearbox always feels a beat slow. When accelerating rapidly, the first gear rises to the second gear and even has a power vacuum period of about 1 second, which wastes a lot of acceleration time.

  After speeding up, the gearbox seems to have changed its personality, judging the driver’s intention more accurately, and being able to shuttle through the city with a 158-horsepower engine. After engaging in the S gear, the throttle response is more sensitive, and the engine is willing to stay at a high speed and wait for your instructions, but there is a process of power transmission to the wheel.

  Yidong chassis has a good thick feeling and solid feedback. In contrast, the adjustment of the suspension is mainly based on comfort. The small bumps on the daily road surface can be well resolved, and it can be easily dealt with in the face of speed bumps. However, when passing at a faster speed, the longer suspension stroke will still have some redundant jumps. In addition, the lateral support force of suspension is not its strong point, and the body roll is more obvious in fast doubling and cornering.

  The steering wheel is moderate in size, full in grip and light in steering, which is suitable for female drivers. However, the strength of the steering wheel will not sink with the increase of the vehicle speed, and it will not sink after being engaged in the S gear. You need to hold the steering wheel tightly when driving at high speed.

  In terms of noise, it has a certain improvement compared with the old models. When driving at a speed of 80km/h in the city, wind noise and tire noise can be controlled within a good range. When driving at a high speed of 120km/h, the engine speed is high (2600rpm), and the engine noise has certain influence on the front passengers.

  The new 1.4T+7-speed dual-clutch powertrain with Yidong Blue Whale version is still biased towards urban households, so it is difficult for you to find sports characteristics in it. In fact, the manufacturer knows the positioning of this car very well. It is just a family car. Treat it gently. It serves you proudly. If you drive hard, its performance may not make you so satisfied.

Shen Teng’s impromptu "skating skills" in the special edition of "Super Family" pokes fun.


1905 movie network news On July 3rd, directed by, starring,,,, Han Yanbo and Bai Lina, the Mahua FunAge fantasy comedy, which will be released on July 21st, will expose a special edition of honest villains. The special edition reveals the process of Shen Teng’s transformation into an "honest villain" begging for help, and the "thick" face of five hours of special effects makeup makes Shen Teng "forget me" to play a foreign villain. Once again, in cooperation with director Song Yang, Teng Ge still appeared as a "skater", from sliding on his knees to the word "foot sliding" in "Super Family", which was a burden and made people look forward to it. Kichikov’s honest character of never telling lies also succeeded in stepping on the audience’s jokes, and Shen Teng’s impromptu comedy ability also added more joy to the role. Looking forward to this summer vacation, I will be happy to cool off and decompress with "Super Family".


Shen Teng premiered as a foreign villain, begging for help.

"The conspicuous bag of the villain" has a name since then.


In the movie, Zheng Qian (played by Allen), an unreliable family, unexpectedly gains super powers. My sister can fly, my father can be invisible, my grandfather can never die, and my sister is powerful. The honest villain (Shen Teng) who has the "money-making ability" is the arch-rival of this family. When a family with "bulk super power" meets a "conspicuous bag in the villain" begging for help, just like Wolong meets Feng Chu, it collides with countless jokes in the process of fighting wits, which makes people look forward to it.

This film is also the first time for Shen Teng to play a foreign villain, with a blond head and a golden-toothed aquiline nose, which makes him feel oppressive from a distance. Once you get close, you will be swayed by the love of the "honest villain" of Kikukov. He threatened generously, lured openly, and others’ sincerity was a killer skill, while begging for help turned sincerity into a "suicide skill", which was simply a "conspicuous package for villains". It is curious what surprises such a comedy character with a sense of contrast will bring.


Apply makeup for 5 hours, remove makeup for 2 hours, and the aquiline nose is too reduced.

Netizen funny comment: This foreign actor is a bit like Shen Teng.


Since Kiqikov was exposed, there have been frequent comments in the comment area that "this foreign actor is a bit like Shen Teng" and "I didn’t recognize Brother Teng". In this special edition, director Song Yang shared the behind-the-scenes story of Shen Teng’s transformation into a beggar through special effects makeup. Shen Teng’s average makeup time is nearly 5 hours, and makeup removal is 2 hours faster, frankly, "the working hours every day are 6-7 hours higher than others".


This time, the special makeup is an all-inclusive semi-headgear starting from Shen Teng’s nose, from improving hairline and cranium, to 1:1 human external nose model, and then to the unification of muscles and skin color, with full details. Director Song Yang revealed that "Brother Teng sometimes shoots for 18-20 hours with a hood". Artificial "thick" face is stuffy and sweaty, which makes Shen Teng experience a "stuffy sweat SPA". However, Shen Teng was quite satisfied with the new look, and bluntly said, "This role is very fresh, which makes me act very presumptuous.".


Improvisation is too strong, and both sheep have comedy burdens.

Laughter is where Shen Teng is on the set.


In the special edition, Director Song Yang bluntly said, "Brother Teng is the only person in my heart who can make everyone get high and excited, with comedy." On the film set, where Shen Teng is, there is constant laughter. Allen, a good partner, also became the "mouth substitute" of netizens and bluntly said, "I want to laugh as long as Brother Teng goes there."


The special also revealed some impromptu performances of Shen Teng during the filming. Shen vacated the scene, and according to the plot of slipping, he had a brainwave to design a sentence, "I am a beggar with slippery feet", which made a pun and poked the punch line. Allen sighed, "Brother Teng’s improvisation ability is too strong". Not only is there a constant burden in the play, but Shen Teng is also a comedian outside the play. On the set, he eats cookies in a game with sheep, and there are questions and answers. The burden falls on the ground, which makes people laugh.


The film "Super Family" is produced by Zhejiang Mahua FunAge Film Co., Ltd., China Film Co., Ltd., Shanghai Alibaba Film Co., Ltd. and Tianjin Cat’s Eye Lithography Culture Media Co., Ltd., released by Shanghai Taobao Film Film Culture Co., Ltd., China Film Co., Ltd. and Zhejiang Mahua FunAge Film Co., Ltd., and will be released nationwide in the summer file on July 21st.

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.
