SUPPLYING COMBUSTION ENGINES IN GENERAL WITH COMBUSTIBLE MIXTURES OR CONSTITUENTS THEREOF

**Definition:** This place covers:

Apparatus for supplying fuel, air or non fuel substances to combustion engines, e.g. carburettors for liquid fuel; apparatus for feeding, or treating combustion-air, fuel, or fuel-air mixture; Fuel injection apparatus

**Glossary:** - Carburettors: Apparatus for mixing fuel with air, the fuel being brought into mixing contact with the air by lowering the air pressure, e.g. in a venturi - Fuel-injection apparatus: Apparatus for introducing fuel into a space, e.g. engine cylinder, by pressurising the fuel, e.g. by a pump acting behind the fuel, and thus includes the so-called "solid-fuel injection" in which liquid fuel is introduced without any admixture of gas - Low-pressure fuel injection: Fuel injection in which the fuel-air mixture containing fuel thus injected will be substantially compressed in the compression stroke of the engine - Pumping element: A single piston-cylinder unit in a reciprocating-piston fuel-injection pump or the equivalent unit in any other type of fuel-injection pump
