Problems solved by technology

[0002] When the diesel generator set is not running at full load or just started, the fan is running at full speed, which causes a waste of power and an increase in fuel consumption of the diesel generator set, and takes away a lot of heat from the engine, especially in extremely cold environments. When the unit is started, the fan is running at full speed, and the engine cannot be warmed up effectively, which accelerates the wear of the engine, reduces the service life of the diesel generator set, and causes a waste of customer resources
