Abstract
A methanol engine cold start system mainly comprises an engine, a methanol oil tank, and a gasoline tank additionally arranged in the system, wherein the gasoline tank is internally provided with a gasoline pump, and the oil inlet pipe of the engine is connected with the C end of a two-way check valve; the A end of the two-way check valve is connected with the gasoline pump in the gasoline tank, and a pressure control valve is arranged between the A end and the gasoline pump so as to ensure the normal fuel oil power of the oil in the engine. The methanol engine cold start system of the utility model is mainly characterized in that a gasoline inlet and return device is additionally arranged in front of the engine, the engine is difficult to be started with the methanol fuel under low temperature, the gasoline pump can be started through pushing a spring button, under the action of the gasoline pump, the gasoline can enter a combustor to burn before the gasoline enters the combustor so as to start the engine. Adopting the cold start system of the utility model, at the temperature of 30 DEG C below zero, under the action of the gasoline pump, the gasoline can enter the combustor to burn before the gasoline enters the combustor so as to start the engine, the methanol fuel burns, and then the start of the engine is followed up.
