Difference Between Diesel Generator and Gasoline Generators

Difference Between Diesel Generator and Gasoline Generators Although diesel generators and gasoline generators are used for emergency power generation, they work differently except for the name and oil. The diesel generator is a diesel engine that drives the generator to convert the energy of the diesel into electrical energy. The gasoline generator is a gasoline engine that drives the generator to convert the energy of the gasoline into electrical energy. The following is a detailed introduction to the difference between the two. Working principle of diesel generator In the cylinder of the diesel engine, the clean air filtered by the air filter is fully mixed with the high pressure atomized diesel fuel injected from the injector. Under the upward extrusion of the piston, the volume is reduced and the temperature is rapidly increased to reach the ignition point of the diesel. The diesel is ignited, the mixed gas burns violently, the volume expands rapidly, ...

How the Fuel Regulating System of Diesel Generator Set Works

How the Fuel Regulating System of Diesel Generator Set Works The fuel speed control system is the main component of the diesel engine. It consists of oil pump, fuel filter, fuel injection pump, governor, fuel injector, high pressure oil pipe oil return pipe. The oil pump sucks the fuel from the fuel tank and sends it to the fuel filter. After filtering, it enters the fuel injection pump. After the fuel pressure of the fuel injection pump is increased, the fuel supply amount required by the same working condition is sent to the high pressure oil pipe. The injector is finally sprayed into the combustion chamber through the nozzle of the injector. In order to maintain the appearance and surrounding fuel cleaning of the diesel engine, a small amount of fuel flowing out of the fuel return pipe from the side of the injector should be returned to the fuel tank by the user. The reliability of the operation of the fuel speed control system directly affects the performance of...

How to Judge the Working State of Diesel Generator Set by Sound

How to Judge the Working State of Diesel Generator Set by Sound Diesel generator set belongs to mechanical equipment and is prone to malfunction during long working hours. The common method of judging fault is listening, looking, checking, among which, the most effective and direct method is to judge by the sound of generator, and can eliminate the small fault by sound, in order to avoid the occurrence of major fault. Below shows you how to judge the working state of diesel generator set from the sound . 1. When the diesel engine running at low speed (idle speed) of the diesel generator st, the metal tapping sound of “ blah, blah ” can be heard obviously by the valve cover. The sound was caused by an impact between the valve and the rocker arm, mainly because the valve gap was too large. The valve clearance is too large or too small, the diesel engine can not work properly. The gap between the valve and the valve is too large, the displacement between the rocker arm and t...
