ABSTRACT:
A direct injected internal combustion engine includes a fuel injector associated with a combustion chamber; a fuel metering device to meter fuel for delivery by the fuel injector; and a gas supply in communication with the fuel injector such that the fuel is delivered from the fuel injector to the combustion chamber entrained in a gas. The gas supply is vented to atmosphere or a combustion chamber of the engine in response to sensing of an engine operating condition indicating imminent cessation of operation of the engine. Venting may be achieved, for example, by maintaining the fuel injector open or in communication with the combustion chamber prior to the stopping of the engine on sensing of the engine operating condition which may be reduction of engine speed below a predetermined value or activation of a "stop" switch.
