The base oil tank is provided with a water circuit circulation system; a diesel engine group; a water jacket heater, and the water jacket heater is respectively connected to the water circuit

The system and the diesel engine group are connected, and the water inlet of the water circulation system and the water outlet of the water circulation system are respectively connected with

Electromagnetic valves and cooling radiator are respectively arranged between the water jacket heaters, and the cooling radiator are connected with the diesel engine group. This new Practical uses the water jacket heater and the water circulation system installed in the base fuel tank to heat the fuel in the base fuel tank oil through heat transfer, which not only saves additional auxiliary energy supply for cold start, but also satisfies the need to increase the fuel temperature in the cylinder during the start-up phase of the diesel generator set
