The fuel rail supplies fuel to the fuel injectors mounted directly on the fuel rail. That the fuel is available at the required injection pressure at the start of injection and only minimal pressure fluctuations occur between the individual injections is key. For the gasoline port fuel injection, fuel rails made of plastic or stainless steel are available.
