Research on Cold Start Method and Strategy of Methanol Engine
The methods and strategies to promote methanol engine cold start performance are studied.For methanol engine,the difficulty of cold start is always the pain point of the methanol fuel.Several optimiza-tion and technical measures are put forward,including the optimization of injection strategy,increasing start speed,and engine pre-heating.Above methods and strategies have improved the cold start perfor-mance of methanol engine to varying degrees.The methanol engine started smoothly at the ambient tem-perature of-30℃in Mohe,China.
