摘　　要：随着各国汽车保有量的增加,汽车售后服务市场不断壮大的同时,带来的环境污染问题日趋严重,各国的环保意识也随之增强,陆续颁布实施了更为严格的汽车尾气排放标准,要求汽车生产企业通过提高车辆技术水平严格控制汽车尾气排放,OBD系统由此产生。衡量发动机的主要技术参数是动力性、经济性、环保性。汽车发动机故障会直接影响环保性。当发动机出现故障时会在仪表上出现发动机故障指示灯(简称OBD)点亮,提示车辆驾驶员进行修理。发动机OBD灯亮是汽车售后常见的故障之一,本文主要介绍大众汽油发动机OBD灯亮的原理分析,并结合实际维修中的案例,来达到精巧修复的目的。The failure of a car engine can directly affect environmental friendliness.When an engine malfunction occurs,the engine malfunction indicator light(OBD) will appear on the instrument panel,affecting the performance of the engine and prompting the vehicle driver to repair.Engine OBD light on is one of the common faults in automotive after-sales service.This article mainly introduces the principle analysis of Volkswagen gasoline engine OBD light on,and combines practical maintenance cases to achieve the goal of delicate repair.
