Abstract
An engine comprises a combustion chamber and a fuel transfer passage having a fuel outlet port communicating with the combustion chamber. A primary fuel delivery system communicates with the combustion chamber and introduces fuel from the fuel source into the combustion chamber. The engine further comprises a fuel pump which is adapted to be connected with a source of fuel and a fuel return line having a first end communicating with the source. A mechanism selectively controls the communication of the fuel pump with either the fuel return line or the fuel transfer passage, so that an enriched flow of fuel can be selectively supplied to the combustion chamber prior to and after starting.
