Abstract
The invention concerns a direct injection internal combustion engine comprising a camshaft and at least two cylinders (1), having in each cylinder a mobile piston (2) associated with at least to intake valves (4, 5), each located in an induction pipes (8, 9), and at least an exhaust valve (6, 7). The displacement of said valves is independent of the rotation of the camshaft and is controlled by a computer (15). The induction pipes (8, 9) are designed to produce an air velocity field inside the cylinder (1) parallel to said cylinder axis. The computer (15) controls, cylinder by cylinder, the opening and closing times of said at lent two intake valves (4, 5) to adapt the shape of the air velocity field inside the cylinder (1) to the engine power.
