Abstract
In a gas fuel engine, a first air-fuel mixture having a local excess air factor λ not less than 2 is combusted (a first combustion). When a target torque is not sufficiently obtained by the first combustion, a fuel is directly injected into a combustion chamber to form a second air-fuel mixture having a local excess air factor λ less than 1.1, so that a second combustion is performed. The combustion of the air-fuel mixture is switched from the first combustion to the second combustion in one combustion stroke.
