Abstract
A device (4, 5) for introducing, under pressure, a fuel-air mixture into a first cylinder of an internal combustion engine, with the engine comprising at least one other cylinder having a pump crankcase. A connecting passageway (9) is provided between the pump crankcase (12) and the upper part of first cylinder (1), with the passageway being supplied with fuel. A communication between the passageway and the combustion chamber of the first cylinder is blocked, and a non-zero angular offset exists between the cycles of the cylinders. The device (4, 5) controls the start of injection by interrupting, in an intermittent and predetermined fashion, the communication between the passageway (9) and the pump crankcase.
