某款柴油车整车燃油消耗优化浅析

The Fuel Economy Optimization and Analysis Of one diesel vehicle

在车辆开发过程中,整车动力性和燃油消耗是设计人员需要关注的两个方面,文章旨在介绍通过发动机万有特性曲线的优化和传动系速比的匹配优化,来实现整车动力性能变化不大、整车油耗明显优化的目标。

During the research and development of one vehicle,the power performance and fuel economy are two aspectsthat engineers concern.This paper is aimed at introducing the optimization of engine universal performance characteristicsmap and the matching of transmission ratio which helps to achieve the goal of reducing fuel consumption of one diselvehicle,while the power performance stlightly changes.
