研究了提升甲醇发动机在低温下起动标定的策略方法.对于甲醇发动机,低温起动困难一直是甲醇燃料的痛点问题,提出多种优化及技术措施,包括喷油策略优化,起动转速提升,预加热等措施,都不同程度地提升了甲醇发动机的低温冷起动性能.在漠河环境温度-30℃,甲醇发动机可以顺利起动.
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.
