A long history electronic direct injection main components of the gasoline direct. Already the majority of european market gasoline engines, in 2017 they will be almost a half of global gasoline engine production. However, whilst the technology might be more modern than tradition port. Gasoline direct injection gdi engines typically emit higher particulate number pn emissions than conventional port fuel injected pfi engines due to the reduced time for fuel atomization in the combustion chamber and the greater possibility of fuel impingement on the cylinder surface. Direct incylinder injection of gasoline eliminates the formation of a liquid fuel film, found on intake port walls in pfi engines, and reduces fuel metering errors and fuel transport delay.
