Never lost on paper, never won in actual combat. Why are domestic engines with good parameters but average performance?

Why do you always say that Chery has the strongest engine autonomy? Look at the actual installed performance and you will know what is a real cow and what is bragging!

In recent years, engines of independent automobile brands have blossomed, such as Chang 'an Blue Whale Engine, which announced to achieve 40% ultra-high thermal efficiency. Dongfeng 1.5T engine has produced superior power performance, with the maximum power of 203 HP and the maximum torque of 320 N m. The maximum power of 2.0T engine of Great Wall 180kW and the maximum torque of 385nm exceed that of 2.0T engine of joint venture brand. Chery's engine parameters are not strong, why is it always said that Chery's engine autonomy is the strongest?

The main reason is that some independent brands of engines are better than Fang in parameters, but they are completely exposed after installation, and their power and thermal efficiency cannot be reflected.

First look at the horsepower achievement rate. BBA models can generally reach a horsepower achievement rate of more than 95%, and American and German brands can basically reach more than 80%. Because lexus ES is a CVT gearbox, it can't be locked at the maximum speed, so it suffers some losses when testing horsepower. The horsepower achievement rate of Sylphy and Fit is really low, but they are both CVT gearboxes, which suffered some losses during the test, but when it comes to domestic brands, Haval H6, Changan CS75PLUS and Changan. This performance is really unsatisfactory. In other words, what's the use of high engine power? The low power transmitted to the wheels means that good steel is not used on the blade, but wasted.

However, Chery's engine surprised us again, and the horsepower achievement rate reached 85%. What level is this? Close to JEEP commander-in-chief, it is the highest among the independent brands tested. So don't just look at the parameters, the horsepower achievement rate is more important than the parameters.

Looking at fuel economy, some engines with a thermal efficiency of more than 40% have higher fuel consumption. As we all know, it may surprise you to look at the fuel consumption data of a certain brand of bears.

Let's take a look at the fuel consumption of Bear. The fuel consumption of Chery engine per 100 kilometers is 8.42 liters for the Tiggo 8 1.6T version and 8.02 liters for the manual version1.5t, ranking first in the list of intermediate SUVs, which is lower than the fuel consumption of joint venture vehicles such as Volkswagen and Toyota. Among the top ten, Chery accounted for four, which is why Chery's engine is a real cow.

Regarding the fuel consumption of bears, I believe there is no need for more popular science. It records the fuel consumption and mileage of car owners, not the fuel consumption, but the data of car owners all over the country. The more data samples, the smaller the error, which can be said to be the most authoritative fuel consumption data.

It can be seen from the measured horsepower achievement rate and fuel consumption of the owner that why Chery's engine, with average parameters and the highest thermal efficiency less than 38%, has been called the strongest engine in China. Some things are not just talk, it depends on the actual installed performance, and it is clear at a glance who is bragging and who is a real cow.

Serious nonsense! As long as the parameters of the engine are good, the performance will certainly not be bad, which is for sure. For example, an automobile engine, no matter how good its performance is, should also be well matched with the gearbox. Only when the engine is perfectly matched with the gearbox and chassis can its performance advantages be exerted. No one aspect will drag down the performance of the engine. In this case, no matter how advanced the engine is, it cannot exert its excellent performance. This issue, whether domestic, imported or joint venture, is no exception. Therefore, it is typical ignorance to say that the engine parameters are good and the performance is average!

Can your child grow up in a day or two? China's research on engines, especially fighters, has just started for more than ten years. Facing the technical blockade of the United States and Europe, our country has independently developed many breakthrough engines, which may not have been reported to you. In the near future, China's engines will surpass those of the United States and Europe. This is not a legend, this is an effort, and this is the inevitable result. ...

Most people who say this have never touched domestic cars, and always feel that imported cars have face, even if they are reduced by hundreds of thousands, only three sofas and four wheels are left [covering their faces]

This is a false question. The power of Chery 1.6T and 2.0T engines are 197 and 254 respectively, and the torque is 290 and 390 respectively. Compared with Volkswagen EA888 engine, both of them should be surpassed. The 2.0T landing of the moon and the moon has already erupted at a huge price difference through the public's Tuang (net income). There is only evidence that one hundred people can speed up and win completely. Can you say it's not an armchair strategist's victory? Supporting national brands and domestic production is a necessary condition for a nation and a country to grow from big to strong.

It is not intuitive to put power torque and fuel efficiency parameters together with consumers. Consumers feel two parameters: 0- 100km/h acceleration time and fuel consumption per 100 km. I guess the general reason for the actual performance of domestic engines is that the matching of gearbox and the optimization of vehicle weight are not in place.

Some things are just strange, like Civic, with small torque, fast acceleration and low fuel consumption. Mercedes-Benz glb200 also has average torque, large body and good fuel consumption. The acceleration is 9 seconds, but many domestic cars have high torque and the acceleration is also outside 9 seconds! Fuel consumption is not bad.

These basic materials, such as metal materials, rubber parts and assembly technology, still have a certain gap with foreign countries. It is this that determines the performance of the engine. I wish the motherland's basic material technology catch up and lead the world!

This is the same as the CPU of a mobile phone. There are still many gaps between MediaTek and Qualcomm.

When it comes to Volkswagen's premium cars, many people think it's a joke. In fact, it does have some advanced places. Looking at the parameters, basically the car of the same class looks better than the parameters, but it may not really run.
