摘要： The internal combustion engine (1 ) comprises a plurality of cylinders (3), an air intake line (5) capable of carrying intake air towards an engine intake manifold (4), and an exhaust line (7) capable of collecting,, exhaust gas from an exhaust manifold (6). The internal combustion engine (1 ) also comprises an EGR line (12) capable of rerouting a part of the exhaust gas from the exhaust line (7), through an EGR cooler (14), towards the air intake line and at least a first turbocharger comprising a first turbine (15) driven by the exhaust gas flowing towards the atmosphere, mechanically linked to a first compressor (16) located on the air intake line (5). The internal combustion engine further comprises an EGR turbine (17) located on the EGR line (12) upstream from the EGR cooler (14), driven by the EGR gas flowing in the EGR line (12). Thus, EGR gas flowing from the exhaust manifold goes through the EGR turbine prior to entering the EGR cooler. Due to the pressure reduction occurring in the turbine, the EGR gas temperature is lowered at the intake manifold inlet, and less cooling power from the engine cooling system is required to cool down the EGR gas in the EGR cooler.

摘要： The invention relates to an internal combustion engine (1) comprises a plurality of cylinders (3), an air intake line (5) and an exhaust line (7) collecting exhaust gas. The engine (1) also comprises an EGR line (12) for rerouting a part of the exhaust gas from the exhaust line (7) towards the air intake line and at least a first turbocharger comprising a first turbine (15) driven by the exhaust gas flowing towards the atmosphere, linked to a first compressor (16) located on the air intake line (5). The engine further comprises a variable geometry EGR turbine (17) located on the EGR line (12), driven by the EGR gas flowing in the EGR line (12). Thus, thanks to the pressure reduction occurring in the turbine, the EGR gas temperature is lowered, and less cooling power from the engine cooling system is required to cool down the EGR.

摘要： A piston (2) is movable in a cylinder (3), between a top dead center position and a bottom dead center position, and equipped with at least a piston ring (21, 22) sliding against an internal surface (31) of the cylinder. The cylinder (3) is provided with a layer (6) of heat insulating material near the cylinder head (4). The ring (21, 22) is kept away from this layer (6) when the piston (2) is in its top dead center position. Fuel injection (F 2 ) within the cylinder starts when the piston (2) is in its upward movement (F 1 ) from its bottom dead center position to its top dead center position and the injected fuel (F 2 ) is directed, upon injection, towards the heat insulating material layer (6).
