奥迪燃油直喷(FSI)发动机的构造与性能分析

AUDI 2.0T engine FSI Fuel Stratified Injection system

奥迪2.0T汽车采用了汽油直喷（FSI）发动机。汽油直接喷入燃烧室,采用连续可变进气歧管,实现了无节流变质调节,提高了充气效率。在发动机排气端安装排气再循环系统。

Audi 2.0T adopt FSI engine.In the gasoline engine,the gasoline injected into the combustion chamber straightly,in the intake passage,FSI engine adopt continue alterable intake manifold,the electronic system control the required air,realized no throttle adjust,advanced the charge efficiency,at the exhaust end,it installed a discreteness which control the exhaust effective,namely the exhaust recycle system.Another two catalysis transform module is FSI technique＇s characteristic.
