In internal combustion engines, etc. direct injection gasoline, or GDI a species different from the fuel injection, which is used in modern engines two stroke and four stroke petrol is used. In engines, GDI, etc. of gasoline under high pressure placed through the rail joint fuel directly into the combustion chamber of each cylinder to be injected. But in injection multi-point fuel normal) spraying fuel in the manifold, the air, the back of the valve inlet or port of the cylinder occurs. In some cases, and. direct injection of gasoline is capable of combustion with the filling, layering was the combustion of very dilute) to improve the efficiency of fuel and reduce the level of emissions in the low load engine make.
