Why does the power of diesel generator sets decrease?

Some friends reported that the power of the diesel generator set will decrease after working for a period of time. What's going on? Haixing tells you that this is related to the environment and climate of the generator set used, and Haixing technicians will give an answer below.
It has been known from the working process of the diesel engine that diesel is injected into the cylinder and mixed with hot air and then ignites and burns to produce power. Therefore, the horsepower of a diesel engine is naturally related to the amount of air and the amount of diesel that can be burned. In places with high altitudes, due to the decrease in atmospheric pressure, the air density decreases, and the weight of the air inhaled into the cylinder also decreases accordingly, which limits the amount of diesel that can be burned and the horsepower decreases. For the same reason, high air temperature and high humidity will also reduce the horsepower of the diesel engine. Therefore, when using diesel engines in different regions or under different atmospheric conditions in the same region, this power change should be considered. For example, the same diesel engine can emit lower power in summer than in winter. For example, the same diesel engine can emit lower power in summer than in winter.
