In-cylinder injection engine with supercharger

摘要

A fuel injection system for an internal combustion engine, and particularly a supercharged one that employs both an in-cylinder injector and a manifold injector. By using two fuel injectors, one in-cylinder and one in the intake manifold, it is possible to operate under light loads with stratified charge and obtain a good homogenous mixture for combustion in other engine speed and load ranges.
