发动机起停技术的研究

Research on Engine Start-stop Technology

汽车工业的快速发展,不但给石油资源带来了巨大压力,同时也产生了极为严重的环境污染问题。为了实现"节能减排"的发展目标,开发了起停技术,它可以改善燃油经济性,提高排放性能,具有巨大的发展潜力。文章介绍了起停技术在混合动力车中应用,包括微混技术和轻混技术;指出了该技术应用面临的问题——启动速度慢、发动机磨损及影响乘坐舒适性等;介绍了博世、马自达及丰田的研究进展。指出加装起停系统后,汽车的燃油经济性得到改善,排放性能提高。

With the rapid development of auto industry, it brought great pressure to petroleum resources, and it led to serious problems of enviromnental pollution. In order to achieve the development goals of energy conservation and emission reduction, start-stop technology is developed, it can improve fuel economy and emissions performance, and it has great potentiality. In this paper the application of start-stop technology in hybrid-powered vehicle was introduced, such as micro-hybrid technology and light mixed technology. The facing problems of slow star-up, engine wear and riding comfort were also pointed out. And research status of Bosch, Mazda and Toyota were described. It is indicated that installation of start-stop system can improve fuel economy and emission performance.
