The inlet system has 2 or more inlet valves (3) for each cylinder incorporated in the engine cylinder head, each controlling a respective inlet channel (6), one of which acts as the main channel, the other acting as a secondary channel, provided with a variable throttle, in the form of rotary slider (8). The slider is rotated coaxial to the inlet valve, with a radial opening (10) brought into alignment with the inlet channel, in dependence on monitored engine operating parameters, e.g. the revs and air intake rate. The air entering via the main inlet channel is directed towards the spark plug, that entering via the secondary inlet channel causing turbulence in the cylinder space, with fuel injected into each air flow via a respective fuel injection device. <IMAGE> |
