What are the reasons why diesel generator sets are difficult to start?

The diesel generator set has a difficult situation to start, then what is the reason for this situation? Diesel generator set manufacturers to take you to a detailed understanding.

1: If the oil pipe interface is loose or broken, at this time there will be air into the system, then there is air or water inside the fuel system, at this time, water appears in the diesel, to a certain extent after it will affect the normal start of the equipment.

2: Many users in the use of diesel generators, may not pay attention to whether there is enough diesel in the tank, if the diesel is used up is not added in time, or the equipment of the tank cap is blocked by stains, then the inside of the tank can not communicate with the external atmosphere, after the oil level drops, the tank will produce negative pressure, thus affecting the diesel supply. If the oil supply is interrupted, the equipment will be affected to start and use.

3: The injector injection time has an impact on the start of the equipment. For example, if the injector injection time is too early, then the internal air pressure does not reach the required value, the temperature in the cylinder will be relatively low, the combustion performance of the diesel engine is not good, and the combustion is incomplete. If the injector injection time is late, the time to inject oil into the cylinder will be missed, which will make the equipment increase, and a large amount of diesel has not been fully burned. Therefore, the oil injection time is too early or too late, will affect the use of equipment, affect the normal start.

4: The temperature will also have an impact on the start-up of the equipment. Especially in winter, the temperature is low, the viscosity of the internal diesel is too large, the lubrication is not good, the oil is full, the power of the generator is insufficient, and the speed is slow. The temperature of the combustion chamber can not meet the temperature requirements of diesel combustion, and the fuel injection quality is not good, which affects the start and makes the start difficult.
