Abstract

Compression ignition engine having at least one: cylinder whose bottom includes a pre-chamber communicating with the cylinder by a transfer channel, the piston being provided with a protuberance adapted to penetrate the transfer channel towards the end of the stroke of compression, a fuel injector that opens into the pre-chamber and directs the fuel jet to the transfer channel, characterized by the combination of the following elements, which allows to obtain that the combustión is developed at a sensibly constant pressure. In the cylinder, a) the transfer channel flows into the pre-chamber through an opening whose smaller diameter, expressed in millimeters, has a maximum value equal to 0.6 d3/4, where d is the measurement in millimeters of the diameter with inner hole of the cylinder, b) the annular clearance between the protuberance and the wall of the transfer channel has, when the plunger is n the high dead center, a value expressed in millimeters equal to maximum at 0, 05 d3/4, where d is expressed in millimeters and, c) the height of the protrusion is fixed so that during the down stroke of the piston, the section of gas passage between the protrusion and the end of the wall of the transfer channel is equal to the minimum opening section of the transfer channel in the pre-chamber when the piston is displaced from the high dead center by an equal distance a maximum of a first value determined by the displacement of the piston from the high dead center (pmh) that causes a rotation of the crankshaft identical to the rotation of this crankshaft during the entire injection time at full load, and the same for another part, at least, to a second value that is half of said first value.
