What is the reason for the difficulty in starting the diesel generator set? The diesel generator set editor will take you to have a detailed understanding.

1. If there is looseness or wear or rupture at the oil pipe interface, air will enter the system, and there will be air or water inside the fuel system. At this time, water will appear in the diesel, which will affect the normal start-up of the equipment after reaching a certain degree.

2. Many users may not pay attention to whether there is sufficient diesel in the fuel tank when using a diesel generator. If the diesel is used up and not added in a timely manner, or if the ventilation hole of the equipment's fuel tank cover is blocked by dirt, the inside of the fuel tank cannot be connected to the external atmosphere. After the oil level drops, the fuel tank will generate negative pressure, which will affect the diesel supply, cause fuel supply interruption, and affect the start and use of the equipment.

3. The injection time of the fuel injector has an impact on the start-up of the equipment. For example, if the fuel injector injects fuel too early, the internal air pressure does not meet the required value, the temperature in the cylinder will be relatively low, and the combustion performance of the diesel engine will be poor, resulting in incomplete combustion. If the fuel injector injects fuel too late, the timing for injection into the cylinder is missed, which will cause the equipment to increase and a large amount of diesel to be discharged before it is fully burned. Therefore, if the fuel injection time is too early or too late, it will affect the use of the equipment and affect normal startup.

4. The temperature can also have an impact on device startup. Especially in winter, when the temperature is low, the viscosity of the internal diesel is too high, the lubrication is not good, and the engine oil becomes full. The power of the generator is insufficient, and the speed slows down. If the temperature of the combustion chamber does not meet the temperature requirements for diesel combustion, the fuel injection quality will be poor, which will affect the start and make it difficult to start.
