Background

The EGR of the automobile produced at present is mainly a single-passage valve body, which is an exhaust gas purification device provided for nitrogen oxides NOx, which is one of harmful gases in engine exhaust. However, the existing EGR mainly has the problems of inaccurate control, high failure rate and the like. Most of the EGR in the market is designed for gasoline engine passenger cars, because most of gasoline engines have small displacement, mainly use light-weight torque drivers and do not need to use brackets. However, the displacement of diesel commercial vehicles is large, large-torque intelligent actuators must be used, and the presence of a bracket is required due to the large weight. The supports of many other products utilize the bolt fastening on the valve body, and long-time use causes the support to drop easily, and the product is inefficacy.
