针对寒区用户的商用车燃油供给系统方案及优化

针对寒区商用车冬天无法使用高标号柴油现状,文章对比市场上常见的几种燃油加热方案,提出了一种新的水加热式燃油加热方案,方案所选用的燃油换向阀具有延时功能,可有效避免高标号燃油混入低标号燃油中,造成低标号燃油污染。该方案安全性高,同时能很大程度上降低行车成本,为寒区柴油商用车市场的发展奠定基础。

Supply System Scheme And Optimization For Customers In Cold Regions

In view of the current situation that commercial vehicles in cold regions can’t use high-grade diesel in winter,this paper compares several common fuel heating schemes in the market,and proposes a new water heating fuel heating scheme.The fuel reversing valve selected in this scheme has a delay function,which can effectively avoid the high-grade fuel mixing into the low-grade fuel,resulting in the low-grade fuel pollution.The scheme has high safety and can reduce driving cost to a large extent,which lays a foundation for the development of diesel commercial vehicle market in cold regions.
