The sequel of high temperature in diesel engines are

1. Engine power reduction: When the car is driving at a low speed with a temperature above 35 ℃, downwind or high load, the phenomenon of engine overheating becomes more severe, further reducing the engine's inflation coefficient, resulting in a decrease in the amount of fresh mixture entering the cylinder, a decrease in the average effective pressure of the cylinder, and a decrease in engine power,

2. Rising fuel consumption: When the engine temperature is too high, it is easy for the lubricating oil entering the cylinder to form gum carbon deposits under high temperature and oxygen deficient conditions. The carbon deposits accumulate on the piston top, combustion chamber wall, valve top, and spark plug, forming a hot spot, causing the engine to ignite hot and produce abnormal combustion. Therefore, it is easy to deform the engine cylinder block and cylinder head, and even produce cracks or warping. It is also easy to burn the cylinder gasket, causing a decrease in cylinder pressure at the end of compression and an increase in fuel consumption,

3. Mechanical wear: Lubricating oil will oxidize and deteriorate due to high temperature, and gum and sediment will adhere to the friction surfaces of piston rings, cylinder walls, and other parts, reducing thermal conductivity. The viscosity of lubricating oil decreases, the oil pressure decreases, the lubricity deteriorates, and the oil film on the cylinder wall weakens under the influence of impact loads, thereby exacerbating the wear of the components.

In short, the issue of high temperature in diesel engines needs to be resolved in a timely manner. Understanding the causes of high temperatures and the correct handling methods is crucial for protecting the normal operation of the engine. Drivers can prevent high temperature problems by supplementing or replacing coolant, regularly checking the cooling system, and avoiding long-term overload work. Of course, in situations where it is not possible to handle it, it is recommended to have professional maintenance personnel handle it to ensure driving safety.
