Abstract
In an engine fuel injection apparatus including an injector having a fuel injection valve for injecting fuel and an air fuel injection valve that is mounted to a cylinder head so as to inject fuel directly into a combustion chamber with compressed air an increase in the size of the engine and the complexity of the structure around the engine are avoided and the pumping efficiency of a compressed air pump is improved. At least part of the compressed air supply route for supplying compressed air to the injector is provided directly in the cylinder head while passing the area in the vicinity of an exhaust port.
