摘要
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.
Abstract
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.
