What is the reason why diesel generators don't generate electricity?

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

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

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

(3) The diesel generator speed drops or is unstable, and there is a voice of working weakness.

cause analysis

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

① Inject enough fuel with good atomization into the cylinder at a certain time according to certain rules.

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

③ Air and fuel are well mixed and completely burned.

④ Friction power and accessory power consumption should be as small as possible, that is, the mechanical efficiency should be high.

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