发动机采用废气涡轮增压进气系统的最初目的是加大循环进气量,提高发动机的输出功率,但是人们发现,增压后进气温度提高,混合气可以适当变稀,从而可以使CO和HC的排放量有所降低。所以,汽油发动机目前也开始逐渐采用废气涡轮增压装置,例如,国产一汽奥迪A6 1.8T、一汽奥迪200 1.8T、一汽宝来1.8T和上海帕萨特1.8T等乘用车都采用了带废气涡轮增压器的增压进气系统。下面以一汽奥迪A6 1.8T轿车带废气涡轮增压器的增压进气系统为例,说明电控汽 The original purpose of the engine using exhaust gas turbocharged intake system is to increase the amount of circulating air intake and improve the output power of the engine, but it was found that after the intake air temperature increases, the mixture can be properly diluted, so that CO and HC emissions have been reduced. Therefore, the gasoline engine is currently also gradually adopting exhaust gas turbocharger devices, for example, the domestic FAW Audi A6 1.8T, FAW Audi 200 1.8T, FAW Bora 1.8T and Shanghai Passat 1.8T and other passenger vehicles are used with exhaust turbines Pressurized Intake System. The following to FAW Audi A6 1.8T sedan turbocharger with turbocharger intake system, for example, that the electronic control steam
