摘要： The invention relates to an internal combustion engine, in particular an ignition-sparked engine, specifically of a motor vehicle, comprising an injection device (40) for fuel (42), which is located and configured in such a way that it directly injects the fuel (42) into the combustion chamber (16) of working cylinders (14) of the internal combustion engine, and comprising at least one inlet valve unit per working cylinder (14), said unit having an inlet valve and an inlet valve seat. The invention is characterised in that at least one inlet valve unit is configured with the type of measures that prevent the dissipation of heat, in such a way that increased surface temperatures greater than 380 °C are achieved in the vicinity of the collar (68) of the inlet valve (20) in at least one predefined area (112) of the load-speed map.

摘要： The invention relates to an internal combustion engine, especially a spark injection engine, comprising admission valves (20) and a fuel injection device (40) arranged and configured in such a way that it injects fuel (42) directly into a combustion chamber (16) of the working cylinders (14) of the internal combustion engine.The admission valves (20) are provided, at least in the area of a groove (68) thereof, with a surface which is configured in such a way that it counteracts coking. .

摘要： The invention relates to an internal combustion engine (10) with at least one combustion chamber (16) enclosed by a cylinder (12) and a piston (14) arranged to move therein. A surface of at least one component of the combustion chamber (16) and/or an adjacent chamber, which comes into contact with the air/fuel mixture for combustion or with motor oil, is provided at least partly with a catalytic coating for oxidation of coking residues.
