Engine generator cooling water preheating system

摘要

The present invention facilitates the starting of the engine in winter or in cold climates for the operator''s convenience, minimizes the smoke caused by incomplete combustion at engine start, and improves the lubricity of the engine with preheated coolant. The preheating device operates when the engine is stopped, and the preheating heater operates to convection heat to preheat the coolant inside the engine to maintain a constant temperature. By improving the energy saving and the natural circulation efficiency of the coolant, it provides the coolant preheating device of the engine generator that prevents damage to the preheater and at the same time prevents the occurrence of smoke due to incomplete combustion to prevent environmental pollution In case of engine generator coolant is not required to preheat So as not to cut off the power operation, the unnecessary time and can reduce the waste of energy. When the engine stops, the coolant preheater operates to warm the engine block and oil cooler, as shown in the diagram below, and when the engine is running, the pipeline that circulates the coolant heated by the engine block and oil cooler according to the proper temperature of the coolant. It consists of a thermostat to regulate the temperature and the water pump for forced circulation of the radiator coolant to lower the temperature of the coolant, a cooling fan for cooling the coolant passing through the radiator and the engine generator preheating device of the present invention.
