Why does the diesel generator not generate electricity?

Introduction What is the reason why a diesel generator does not generate electricity? The so-called insufficient power is what is commonly referred to as a "weak" diesel engine. Generally speaking, Cummins diesel generators generally have a certain amount of power.

Why does the diesel generator not generate electricity?

The so-called insufficient power is what is commonly referred to as a "weak" diesel engine. Under normal circumstances, Cummins diesel generators generally have a certain power reserve and can drive working machinery to operate normally. When the power is insufficient, it means that the diesel generator cannot move its working machinery, accompanied by the following phenomena.

①The diesel generator emits black smoke. At this time, a large amount of black smoke came out of the exhaust pipe of the diesel generator.

②The exhaust temperature of diesel generator is high. At this time, the exhaust pipe and the turbocharger turbine are dark red.

③The diesel generator speed drops or is unstable, and there is a sound of inability to work.

Cause Analysis

The power index of a diesel generator is a comprehensive reflection of its technical status. If technically in good condition, a diesel generator can produce enough electricity. When power is insufficient, it is often a comprehensive reflection of various system failures. According to the working principle of a diesel generator, the basic conditions for a diesel generator to generate sufficient effective power are:

① Inject a sufficient amount of well-atomized fuel into the cylinder according to a certain rule and at a certain time.

② Sufficient fresh air will enter the cylinder at a certain time according to certain rules, and the burned exhaust gas will be discharged from the cylinder at a certain time according to certain rules.

③The air and fuel are well mixed and burned completely.

④ The friction power and accessory power consumption are small, that is, the mechanical efficiency should be high.

Therefore, when analyzing the causes of power shortage, we can start from the above basic conditions and analyze the causes according to the system according to the power shortage phenomenon.
