Abstract:
An internal combustion engine, especially an Otto engine, with intake valves and with a fuel injector, which is arranged and designed so that it injects the fuel directly into a combustion chamber of working cylinders of the internal combustion engine. At least in the region of the neck, the intake valves have a surface that is designed to counteract the formation of carbon deposits.
