ABSTRACT:
A direct-injection and spark-ignition 4-stroke internal-combustion engine having at least one combustion chamber (1) including a piston (2), a cylinder (3), a cylinder head (4), several intake lines (5) associated with intake elements (6), an exhaust line (9) cooperating with an exhaust valve (11), and an ignition device (7) positioned close to intake elements (6). The upper face of the piston (2) has a profile close to that of the lower face of the cylinder head (4), and the piston (2) has a recess (12) in the vicinity of the area into which ignition device (7) opens. A fuel injection element (8) is positioned in the vicinity of the ignition device (7), and one of the intake elements (6) has a longitudinal axis close to the longitudinal axis of the cylinder (XX').
