一种常温冷启动修正系数的测试方法

A Test Method for Correction Coefficient of Cold Start at Normal Temperature

冷启动修正系数对循环油耗的仿真结果影响很大,本文采用怠速工况下油耗消耗量变化等效计算出循环工况的冷启动修正系数,并采用实车进行试验对比,利用仿真进行差异性分析。为后续在项目初期采用成本低试验方法简单的冷启动修正系数的测量提供一种参考。

The cold start correction coefficient has a great influence on the simulation results of cycle fuel consumption.This article uses the fuel consumption change under idling conditions to equivalently calculate the cold start correction coefficient under the cycle conditions,and uses real vehicles for test comparison and simulation to analyze differences.The article provides a reference for the subsequent measurement of the cold start correction coefficient using a low-cost test method at the beginning of the project.
