Study of Matching Technology of Electronic Control System and Performance for Motorcycle Engine

在FY125-3P摩托车的FY156FMI发动机上,采用闭环电控技术,进行发动机与整车的优化匹配,与原化油器车相比,测得所开发的电控摩托车工况法CO、HC和NOx的排放量显著减少,低于欧Ⅲ排放限值的70%;发动机外特性燃油耗下降了15.9%;后轮驱动功率和最高车速稍小于化油器车,加速性能优于化油器车,尤其是超越加速性能提高明显。

Based on FY156FMI engine for FY125-3P motorcycle, the paper studied matching technology of engine and vehicle for closed-loop electronic control system. Comparing with the original carburetor motorcycle, the emissions of CO, HC and NOx for electronic control engine motorcycle developed were reduced largely, and is lower than 70% of limit value in European emission standard Ⅲ. The fuel consumption was reduced by 15.9%, driving power of rear wheel was little lower, and the accelerating performance, especially the overtaking acceleration was improved obviously.
