ABSTRACT:
An internal combustion engine comprises a combustion chamber and a crankcase which extends from the combustion chamber. A primary fuel delivery system introduces fuel from a fuel source into the combustion chamber, and a primer fuel delivery system is selectively operable for introducing fuel from the source into the combustion chamber in addition to fuel which is introduced by the primary fuel delivery system. A collector assembly communicates with the crankcase for accumulating residual fuel from the crankcase, and a residual fuel delivery system supplies fuel from the collector assembly into the combustion chamber. A control valve mechanism is connected to the primer fuel delivery system and the residual fuel delivery system for blocking the supply of fuel by the residual fuel delivery system during operation of the primer fuel delivery system.
