Note(s)
In this subclass, the following term or expression is used with the meanings indicated:[4]"fuel injection" means the introduction of a combustible substance into a space, e.g. cylinder, by means of a pressure source, e.g. a pump, continuously or cyclically acting behind the substance;"supercharging" means supplying to the working space, e.g. cylinder, combustion-air pressurised by means of a pressure source, e.g. a pump. Attention is drawn to the Notes preceding class F01.In this subclass, electrical aspects of control arrangements are classified in groups F02D 41/00-F02D 45/00
