Introduction and noise diagnosis and trouble shooting of heavy truck engine

In the automobile industry, heavy truck is the Goldbach conjecture of automobile technology, and more importantly, heavy truck engine is the crown of Goldbach conjecture.All the advanced technology and high-end specs in luxury cars were, and still are, second-hand technology in high-end heavy trucks.

Therefore, from a general point of view of the latest technologies and fashions in the automotive industry, the criterion to measure the crown’s qualification will be heavy-duty truck engine technology.Although some Chinese manufacturers have cloned some high-end trucks, they are still far behind international truck leaders.Without thirty years of dedicated study and hard work, the gap will not be closed.

Considering that China’s exhaust standards are constantly improving, and the control and management of overload are constantly increasing, the trend of large horsepower and large exhaust is already obvious.

In recent years, due to the lack of engine core technology, this is clearly the bottleneck of China’s heavy truck development.Under the conditions of technology trading markets, Chinese manufacturers are fighting with different Allies for market share through many collaborations.
