INTERNAL COMBUSTION ENGINE, IN PARTICULAR WITH DIRECT INJECTION, WITH A PISTON PROVIDED WITH A TROUGH COMPRISING A DOG POINT |
摘要 |
<p>The invention concerns an internal combustion engine, in particular with direct injection comprising at least one cylinder (10), one piston (30) sliding in said cylinder, a combustion chamber (26) delimited on one side by the upper side of the piston including a concave trough (32) wherein is arranged a dog point (34) with apex angle (a2) and a fuel injector (22) for injecting fuel at a spray angle (a<SUB>1</SUB>) not greater than 2 Arctg CD/2f where CD is the diameter of the cylinder (10) and F the distance between the point of origin of the fuel jets derived from the injector and the position of the piston (30) corresponding to a crankshaft angle of 50° relative to the upper dead center. The invention is characterized in that the apex angle (a<SUB>2</SUB>) of the dog point is greater than the spray angle (a<SUB>1</SUB>) by an angle ranging between 30° and 60°.</p> |
