奔驰C63 （国六）升级Velocita-VE智能5G高性能头段

奔驰C63 AMG 4.0升V8双涡轮发动机，双涡轮增压进气和汽油直接喷射系统相结合，提高了热力效率，狂野动力汹涌而出；匹配AMG SPEEDSHIFT MCT 9速运动型变速箱，搭载AMG动态操控选择变速箱模式，引爆疾驰震颤！Mercedes Benz C63 AMG 4.0-liter V8 twin turbine engine, dual turbocharged intake and gasoline direct injection system, improve thermal efficiency, wild power surging out; match AMG speedshift MCT 9-speed sports gearbox, equipped with AMG dynamic control, select transmission mode, detonate galloping tremor!头段的功效The effect of head section排气系统中的大部分阻力都来自于三元催化器，尤其在国内进入新的国六排放标准，原厂车由于对排放的标准十分严谨，往往会增加头段上触媒的数量而且使用阻力较大的陶瓷催化使声音更加难以释放。所以在更换排气时，三元催化头段的改装也是需要着重考虑的。Most of the exhaust system resistance comes from the ternary catalysts, especially in the domestic into six new countries emissions standards, original car because of emissions standards is very rigorous, tend to increase the number of head section on the catalyst and the use of larger resistance ceramic catalytic make sounds more difficult to release. So in replacing exhaust, ternary catalytic modification of the first paragraph is also need to think about it.头段的功效主要来自其中的三元。相对来说，三元越密过滤尾气的效率越高，同时消音效果也越好，但弊端是发动机废气排放不畅，缸内会残留部分废气，降低缸内含氧量从而限制部分动力。The effect of head section mainly from three yuan. , three yuan are relatively dense filter exhaust efficiency higher and higher, at the same time the silencing effect is better, but the disadvantages are poor engine exhaust emissions, will remain part of exhaust gas in cylinder, the lower cylinder containing oxygen limiting part.
