起步加速工况下进行补气可在一定程度上解决涡轮增压器响应滞后造成碳烟排放量增加的问题。开发了柴油公交车起步加速工况提前补气系统,并进行了实车试验。道路试验结果表明系统能实现预期的补气控制。台架试验结果表明,系统优化进一步降低了柴油公交车起步加速工况的碳烟排放。 To speed up the initial start-up gas can be to some extent to solve the problem of turbocharger response lag caused by increased soot emissions. The diesel bus was developed to speed up the gas supply system in advance and carry out the actual vehicle test. Road test results show that the system can achieve the desired qi control. The bench test results show that the system optimization further reduces the emission of soot in accelerated starting diesel buses.
