<p>An internal combustion engine includes a fuel system having the capability of injecting a fuel and air mixture, or air alone, for providing a secondary air charge directly into the combustion chamber (22) after combustion of a primary air and fuel charge has begun. The secondary air charge functions to increase turbulence in the combustion chamber (22) so as to make more oxygen available to further oxidise unburned hydrocarbon remaining from the fuel charge.</p> |
