Methanol fuel engine and start control method thereof

Abstract

The application discloses a methanol fuel engine and a starting control method thereof, and relates to the technical field of engines. The methanol fuel engine and the starting control method thereof comprise an engine main body, a heat recovery preheating device and an electric auxiliary heating device are installed on the fuel injection cylinder, and the injected methanol fuel is sequentially preheated and electrically auxiliary heated, and the heat source of the heat recovery preheating device is obtained by recovering and storing exhaust heat in an exhaust manifold; compared with the electric heating mode of directly fixing power in the prior art, on one hand, the heat recovery preheating device is used for one-step preheating, and power is saved; on the other hand, a gradient power increasing mode is adopted, power consumption is further reduced, a machine learning model is used for self-learning, and appropriate heating power, fuel injection quantity and timing can be intelligently analyzed and judged according to historical data experience and actual environment data, so that low-power-consumption high-efficiency heating is ensured.
