Zero flow cooling system is a new advanced technical solution for TGDI engine.It consists of integrated exhaust mani-fold,two zero flow control valves and an electronic thermostat.Zero flow control valves control the coolant circuit of oil cooler,cabin heater and bypass circuit in the coolant manifold.Electronic thermostat controls the coolant circuit of radiator.The turbo coolant circuit works,but zero flow valves and thermostat are all closed during engine warming up stage.The zero flow control valves and electronic thermostat will open respectively when the coolant temperature reaches different setting points.The zero flow cooling system can shorten the time spent on engine warming upstage.It can save fuel to improve fuel economy performance for vehicle.Furthermore it can lower en-gine friction,improve engine durability and reliability performance.

为研究直喷汽油机壁面引导型燃烧系统和气流引导型燃烧系统对起燃工况炭烟生成的影响,在光学单缸发动机台架上进行了GDI汽油机燃烧火焰可视化的试验.研究结果表明,汽油机在起燃工况运行时,采用壁面引导型的燃烧系统由于需要活塞对喷雾雾束进行引导以在点火时间窗口内形成容易着火的混合气,导致大量扩散火焰的产生,炭烟生成加剧;而气流引导型直喷燃烧系统避免了喷雾雾束与燃烧室壁面以及活塞顶面的接触,且有组织的强烈滚流
