经济驾驶模式对于车辆排放及油耗结果影响

Analysis of vehicle emission and fuel consumption under ECO driving mode

对一辆带有ECO行驶模式的车辆分别在普通驾驶模式(D档)和EC O行驶模式下进行了NEDC工况常温冷启动排放测试,在常规污染物排放的基础上,重点分析了油耗的变化差异,对发动机参数进行比对。结果表明:EC O行驶模式下油耗结果低于普通驾驶模式下油耗结果 ,常规污染物排放差异不明显。

A vehicle with ECO driving mode was tested under normal driving mode(D gear) and ECO driving mode under normal temperature cold start emission test. On the basis of conventional pollutant emission, the difference of fuel consumption is analyzed emphatically, and the engine parameters are compared. The results show that the fuel consumption under ECO driving mode is lower than that under ordinary driving mode, and the difference of conventional pollutant emission is not obvious.
