AI Technical Summary

Technical Problem

Existing technologies cannot fully explain the difference between actual fuel consumption of motor vehicles and regulatory reference cycles, especially the excessive fuel consumption caused by the specific operating modes of internal combustion engines.

Method used

By implementing a series of steps in the electronic control unit of a spark-ignition internal combustion engine in a motor vehicle, including determining ignition advance and richness/leanness efficiency, calculating instantaneous fuel consumption losses, checking whether strategies affecting these factors are activated, recording and comparing consumption data from multiple strokes, the root cause of excessive fuel consumption can be identified.

Benefits of technology

It can accurately analyze the difference between actual fuel consumption and approved consumption, identify and explain the reasons for excessive fuel consumption, and provide detailed analytical evidence so that manufacturers can make corrections.

Abstract

一种用于分析机动车辆的实际能量消耗的方法(10),包括:‑根据效率(Rend_Av,Rend_Rich)的点火提前效率(Rend_Av)和浓稀度效率(Rend_Rich)以及以升 / 秒为单位的发动机的瞬时燃料消耗(Cons_Inst),计算以升 / 秒为单位的瞬时消耗损耗(Pen_cons_inst)的步骤(13);‑检查影响发动机计算机上搭载的点火提前和 / 或浓稀度的各种策略(S)是否被激活的步骤(14);以及‑在行程(T)上根据针对每种激活策略(S)计算的瞬时消耗损耗(Pen_cons_inst)计算与激活策略(S)相关的消耗损耗(Pen_cons_S_T)的步骤(15)。
