电喷系统控制对轻型汽油车油耗的影响

Influence of EFI System Control on Fuel Consumption of Light Gasoline Vehicle

面对日益严格的油耗及排放法规要求,整车电喷系统控制需要兼顾排放性、经济性、动力性和驾驶性。本文选取一辆轻型汽油车,搭载1.5L自然吸气发动机,通过调整电喷系统控制数据,进行WLTC(国六排放循环)油耗试验,研究电喷系统控制数据对轻型汽油车油耗的影响。

In the face of increasingly stringent fuel consumption and emissions regulations,vehicle electronic control needs to balance the emission fuel consumption and drivability.This study selects a light gasoline vehicle with 1.5L naturally aspirated engine,adjusts electronic control calibration data,experiments with WLTC circulation,and explores the influence about the vehicle fuel consumption.
