Abstract:
1. Internal combustion engine, with direct gasoline injection and controlled ignition, comprising: at least one cylinder, a cylinder head closing the cylinder, a piston slidingly arranged in the cylinder, a combustion chamber defined between the piston and the cylinder head, means for injecting gasoline into the combustion chamber, means for ignition intended to produce an ignition of an air-gasoline mixture in the combustion chamber, intake valves and exhaust valves, selectively closing the combustion chambers, and means for recirculating at least a portion of exhaust gases into the combustion chamber during an air intake phase, wherein a pressure provided to the injection means is above 250 bars, so as to homogenize an air-gasoline-recirculated exhaust gases mixture and to increase a combustion speed.
