Operation steps： 1. Turn on the vehicle power supply: First, turn on the vehicle power supply to make the ECU enter the working state. At this time, the OBD exhaust valve will be monitored and controlled by the ECU. 2. Check the OBD system status: Through the OBD indicator light on the vehicle dashb

The automobile exhaust valve is a valve installed in the automobile exhaust pipe, which is generally used to adjust the size of the automobile exhaust volume and the length of the exhaust gas discharge time. Automotive exhaust valves are generally made of metal materials, mainly composed of valve bo

DPF(Diesel Particulate Filter)的工作原理 DPF（Diesel Particulate Filter，柴油颗粒物过滤器）是柴油车中用于减少尾气中颗粒物（PM）排放的重要装置，其内部结构为陶瓷载体，内部遍布平行的轴向蜂窝孔，孔道和孔道相邻，但是两个孔道内一个只有进口开放，另一个只有出口开放，利用这种曲折孔道使颗粒物存留在载体上，实现过滤效果，以下是DPF的工作原理详细解析： The Diesel Particulate Filter (DPF) is an important device used to reduce the emission of particu
