<p>The engine is characterized by an axial group of two cylinders (2, 7) communicating by means of a channel (22) situated in the cylinder head (20). Both cylinders (2, 7) joined side to side allow for a centralization of both crankshafts (4, 13) in the cylinder case (5). Each cylinder comprises a corresponding piston (1, 6) displaceable in the first cylinder (2) intended for the intake, compression, expansion and exhaust phases, said first piston (1) depending, via a piston rod (3), from the first crankshaft (4) situated in the cylinder case (5). The second piston (6) displaceable within the second cylinder (7) delimiting the combustion prechamber (8) wherein are housed a heating plug and a fuel injector, said second piston (6) depending, via a piston rod (12), from the second crankshaft (13) also located in cylinder case (5). The first crankshaft (4) is connected by means of a transmission to the second crankshaft (13) via the coupler (not shown), the latter varying the timing between the two above-mentioned crankshafts as a fonction of the overboost pressure. The gas pedal (not shown) acts via known means on the amount of fuel to be injected into the combustion prechamber (8).</p> |
