摘　　要：随着家用汽车的不断普及,汽车市场发展迅速,大量的汽车上路行驶,导致城市每天有大量汽车尾气排放,严重污染空气,基于环境保护考虑,各国针对汽车发动机的排放法要求也不断严格化,实现对排气的循环和涡轮增压是重要机内净化途径,这对于提升发动机的排放控制效果也有重要作用。对此,本文说明了增压发动机和排气抽风再循环的关系,并探究增压发动机中排气循环利用技术现状,以宝马汽车为例,分析这类汽车的废弃涡轮增压处理中的氧化传感器设计对实现涡轮增压和空气净化的效用。With the continuous popularization of household cars,the automobile market is developing rapidly.A large number of cars are driving on the road,resulting in a large number of automobile exhaust emissions in cities every day,which seriously pollutes the air.Based on the consideration of environmental protection,the requirements of emission laws for automobile engines in various countries are also being tightened.Realizing exhaust circulation and turbocharging is an important way of internal purification,This also plays an important role in improving the emission control effect of the engine.In this regard,this paper explains the relationship between turbocharged engine and exhaust air recirculation,and explores the current situation of exhaust recycling technology in turbocharged engine.Taking BMW as an example,this paper analyzes the utility of oxidation sensor design in waste turbocharging treatment of this kind of vehicle to realize turbocharging and air purification.
