Abstract: An internal combustion engine with direct gasoline injection and controlled ignition, having at least one cylinder, a cylinder head, sealing the cylinder, a piston, arranged to run in the cylinder, a combustion chamber, defined by the piston and the cylinder head, a gasoline injector into the combustion chamber, an ignition device, for producing an ignition of the air/gasoline mixture in the combustion chamber, inlet and exhaust valves, selectively sealing the combustion chamber and a system for recirculation of at least a part of the exhaust gas into the combustion chamber during the air intake phase, wherein the pressure provided for the injection device is greater than 250 bars, such as to homogenize the air/gasoline/recycled exhaust gas mixture and increase the speed of combustion.

Abstract: The invention relates to an internal combustion engine with direct gasoline injection and controlled ignition, comprising at least one cylinder (1), a cylinder head (6), sealing the cylinder (1), a piston (7), arranged to run in the cylinder (1), a combustion chamber (2), defined by the piston (7) and the cylinder head (6), a gasoline injection means (3) into the combustion chamber (2), an ignition means (4), for producing an ignition of the air/gasoline mixture in the combustion chamber (2), inlet (8) and exhaust (9) valves, selectively sealing the combustion chamber (2) and means for recirculation of at least a part of the exhaust gas into the combustion chamber (2) during the air intake phase, characterized in that wherein the pressure provided for the injection means (3) is greater than 250 bars, such as to homogenize the air/gasoline/recycled exhaust gas mixture and increase the speed of combustion.

Abstract: The invention relates to an internal combustion engine with spark ignition and direct fuel injection. The inventive engine comprises: a cylinder; a cylinder head; a piston which is mounted to slide in the cylinder; a combustion chamber which is defined in the cylinder between the cylinder head and the piston; a fuel injector which opens into the combustion chamber; a spark plug; inlet and exhaust valves; and a fuel injection pump which supplies the injector with a flow of pressurized fuel. According to the invention, the pressure of the fuel flow supplied to the injector exceeds 300 bar and, preferably, reaches or exceeds 500 bar.
