Direct injection internal combustion engine

摘要

The invention concerns an internal combustion engine, especially an Otto engine, with intake valves (20) and with a fuel injector (40), which is arranged and designed in such a way that it injects the fuel (42) directly into a combustion chamber (16) of working cylinders (14) of the internal combustion engine. At least in the region of the neck (68), the intake valves (20) have a surface that is designed in such a way that it counteracts the formation of carbon deposits.
