Reasons for Power Reduction in 150KW Diesel Generator Sets

Dec. 11, 2025

Some users do not pay attention to the daily maintenance of diesel generator sets. After using them for a period of time, they find that the unit power drops and think there is a problem with the unit. In fact, there are two reasons for the power reduction of diesel generator sets: one is the problem of parts cleaning, and the other is the problem of parts wear. Now, Dingbo Power will analyze with you why the power of 150KW diesel generator sets drops.

The main reasons for the power reduction of 150KW diesel generator sets are as follows:

1.The air filter is too dirty, resulting in insufficient air intake. In this case, the air filter must be cleaned or replaced.

2.The fuel filtering device is too dirty, leading to insufficient fuel injection quantity, and it must be replaced or cleaned.

3.The ignition timing is incorrect and needs to be adjusted.

 

Some parts of the 150KW diesel generator set will also affect the power change. Because when the diesel engine, which is the power part of the diesel generator set, is working, many parts slide or rotate at a high speed under a certain load, such as the piston and cylinder liner, crankshaft and bearing, etc. Although the surfaces of these parts are lubricated to varying degrees, with the increase of working time, the surfaces in contact with each other will inevitably wear due to friction, gradually destroying the original size and geometric shape.

 

This normal wear is often called "natural wear" and is unavoidable. In addition, the power of the diesel engine is related to the air volume and the amount of diesel that can be burned. At the same time, the temperature and humidity of the air will also affect the power of the diesel engine. High air temperature and high humidity will also reduce the power of the diesel engine.

 

Diesel generator sets are consumables. As the name implies, consumables refer to items with loss. With the increase of the number of uses and the length of time, the accessories of diesel generator sets will have different degrees of wear. In order to maintain the daily operation of diesel generator sets, it is necessary to replace and repair various accessories. The most effective way to prevent the power reduction of generator sets is to do a good job in daily maintenance, and carry out timely maintenance to ensure the stability of the generator set's work.
