FUEL PRIMER FOR AN INTERNAL COMBUSTION ENGINE

摘要

FUEL PRIMER FOR AN INTERNAL COMBUSTION ENGINE An engine comprises a combustion chamber and interior walls which define a fuel induction passage having a fuel outlet port communicating with the combustion chamber. A first fuel delivery system introduces fuel from a fuel source into the combustion chamber. A second fuel delivery system includes a nozzle which extends into the fuel induction passage adjacent to the fuel outlet port and is selectively operable by means of an associated valve mechanism for introducing fuel from the source directly into the combustion chamber through the nozzle in addition to the fuel which is introduced into the combustion chamber by the first fuel delivery system.
