Antifreeze is an indispensable heat dissipation medium for normal operation of diesel generator set. One is to antifreeze the water tank of the unit, which will not explode due to freezing expansion in winter; the other is to cool the engine. When the engine is running, the effect of antifreeze as circulating cooling liquid is obvious

At low temperature, the viscosity of the fuel increases, which is not conducive to the atomization and combustion of the fuel. The poor fluidity of the lubricating oil increases the resistance of the moving parts. In addition, the working capacity of the storage battery is reduced

The most direct change of brushless motor is that there is no electric spark generated by the operation of brush motor, which greatly reduces the interference of electric spark on remote control radio equipment.

For turbocharged diesel engine, because of low load and no-load, the boost pressure is low. It is easy to cause the sealing effect of supercharger oil seal (non-contact type) to decline, and the oil enters into the supercharging chamber and enters the cylinder with the intake air;

The whole process of generating units put into parallel operation is called parallel operation. One generator set will run first and send the voltage to the bus. After the other generator set is started, it will be paralleled with the previous generator set, and it should be closed at the moment
