In this subclass, the following term or expression is used with the meanings indicated:
"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.
with non-mechanical means for transmitting control impulse; with amplification of control impulse
