An internal combustion engine is provided that can be fuelled with first fuel alone or a combination of the first fuel and a second fuel or the second fuel alone. The engine comprises two separate fuel injection valves each disposed in the cylinder head for respectively injecting the first and second fuels directly into the combustion chamber. With the disclosed engine, conventional cylinder heads can be employed by utilizing the location normally occupied by a glow plug to mount the second fuel injection valve. To provide ignition assistance in lieu of a glow plug, the disclosed engine employs an ignition-assist apparatus that is operative to pre-condition air within the intake air manifold. An electronic controller is programmable to command operation of the first fuel injection valve, the second fuel injection valve and the ignition-assist apparatus responsive to measured engine operating conditions. The method of operating the disclosed engine comprises pre- conditioning air within the intake air manifold before introducing it into the combustion chamber by operating an ignition-assist apparatus; introducing the first fuel directly into the combustion chamber through a first fuel injection valve; introducing the second fuel directly into the combustion chamber through a second fuel injection valve; and selecting one of a plurality of predetermined operating modes for determining when to pre- condition the air, when to introduce the first fuel, and when to introduce the second fuel, with these determinations being made responsive to measured engine operating conditions and operator inputs.
