Abstract
A direct injection gasoline engine includes at least one cylinder, a piston reciprocably mounted within the cylinder, a cylinder head closing the cylinder and at least one inlet port adapted to cause swirl of the inlet air in the cylinder substantially about the axis of the cylinder. The crown of the piston is provided with a recess which has a floor and a side wall and constitutes at least part of the combustion chamber. A spark plug extends close to or into the recess, at the top dead centre position of the piston, at a position adjacent to the side wall of the recess. A fuel injector is arranged to inject fuel into the recess and is situated adjacent the side wall of the recess. That portion of the side wall of the recess which is between the fuel injector and the spark plug is arcuate, when viewed in the axial direction of the cylinder. The floor of the recess adjacent the said portion of the side wall rises progressively towards the cylinder head over at least a part of its length in the direction towards the spark plug.
