汽车发动机起停技术研究及应用开发

Study and Application of Engine Start-stop Technique

摘要: 对汽车发动机起停技术及其方案进行研究, 详细叙述整车配备起停功能的控制原理与应用方案, 并通过对实际样车的研究, 加深对起停技术的实际节油效果和控制原理的认识, 为整车标定做好基础。最后在某型车上开发了全功能的起停技术, 通过精细的整车标定使该车的排放水平达到国四标准, 排放循环的节油效果达到了预期目标, 城市工况的节油效果达到7%。

Abstract: The start-stop technique and the solutions for automobile are studied in this paper. The control strategies are described for an automobile equipped with start-stop technique.In order to obtain high fuel efficiency, the fine calibration is carried out for a certain type automobile. The test results show that the tested automobile can achieve National IV emission standards in China with start-stop technique and in urban condition, the fuel saving can reach 7%.
