Long-term overload operation of diesel engines

The long-term overload operation of diesel engines is harmful:

1. During overload operation, the diesel engine work is intensified, the exhaust pipe emits heavy smoke, and a large amount of carbon deposits are generated. At the same time, the engine temperature rises, the lubrication conditions become worse, and the oil aging and parts wear are aggravated.

2. When overloading, the adjustment does not work, the engine speed drops sharply, the fuel consumption increases, and the power decreases.

3. The engine speed is unstable, and even the flameout stops. The driver has to change gears frequently, so that the number of shifts increases, which not only increases the wear of the parts, reduces the service life, but also increases the working strength of the driver and is prone to fatigue. Please note that the tractor may not be overloaded when the engine is overloaded.

4. When the diesel engine is overloaded for a long time due to traction resistance or overload of the trailer, the tractor is also driven under overload conditions, which not only causes the service life of the tire to drop significantly, but also causes damage to various parts of the chassis.
