Even if you jump out of Chery, the engines designed and manufactured by China can be maintained and driven normally, and most engines can be left on for a long time. I hardly saw any broken engines today. Of course, some engines have some history.
For example, the second generation EA888 is notorious for burning engine oil. At that time, EA 1 13 and some early engines did have poor problems, some were engine problems, some were user problems, such as cracking of cylinder and cylinder gasket caused by antifreeze problems, and some were engine problems caused by untimely maintenance.
Don't worry about the quality of the engine now.
In fact, as far as the engine is concerned, this is a relatively low-tech technical component. Compared with four-wheel drive system, gearbox and adjustment, it is not difficult to produce an engine without problems, because the technical principle is well understood and forging technology has been done well enough at present.
As far as quality is concerned, everyone can do it well. What is bad is the technical expression of the engine, such as fuel consumption, power, noise and balance. These parameters can improve the value of the engine. Admittedly, there is still a lot of room for improvement in domestic cars, but this cannot erase the objective fact of good quality.
Chery has previously reported such a news:
We learned from SAIC Chery Automobile Co., Ltd. that among the first batch of Chery taxis, a red taxi with the license plate number of Anhui B84828 became the object of attention. The car ran 500 thousand kilometers without major repair. According to the owner, this car has run 520,000 kilometers since it was put on the road in 2000 (2003), with an average of more than 600 kilometers per day.
Chery's model is still under the name of SAIC, and the engine of that year has been guaranteed not to be overhauled for 500 thousand kilometers. In the era of mature equipment, skilled technology and technical upgrading, the quality and performance of the engine can be better.
How long can the engine run? Chery said that it can be driven almost all the time, so the engine of its various models promises a 10 year warranty of 654.38+00,000 kilometers. Although this is only the warranty of the core components, it is enough to show their confidence.
From the point of view of ordinary family cars, a family car travels 30,000 kilometers per year, even if it travels 15 years, the mileage is only 450,000 kilometers. Once the mileage threshold is reached, the engine may not be the part that blocks the life of the whole vehicle. It may be that the gearbox broke down first, or the car may encounter some problems, such as an accident, the car can't start, or it may be burnt out or soaked in water.
One more thing, the emission standard has been upgraded, resulting in the exhaust gas not meeting the standard. These are the fundamental factors that restrict the life of the whole vehicle.
Looking back, it is said that the neck technology of our own brand is no longer an engine.
Compared with the engine, how to integrate the power system to make it more perfect, how to develop a four-wheel drive system, how to own its own spare parts industry chain, how to really get rid of the shackles of Aisin and ZF, how to really improve the production quality and optimize the production process are the real goals.
