Diesel engines come in all shapes and sizes with refinements made to the basic principles developed in the late 19th century.. The fuel oil is pushed into the engine under high pressure at the correct time by an injector pump.. The air is forced into a horizontal rotary motion by the design of the air inlet port or valve. Light vehicle diesel engines use a priming pump to remove air from the fuel system. Otherwise, the engine would have to be cranked over with the starter motor, to bleed and prime the system. Inline injection pump. An in-line injection pump meters the fuel and raises its pressure. The basic principle is for a plunger to act on. Fuel injection was a well-known principle long before the First World War, as it was on the original Wright brothers' engine of 1904 and on the Antoinette aircraft engine.. Bosch entered the injection pump and nozzle business for diesel and gasoline vehicles.. The injection system uses a typical rotary-vane fuel pump. For use on cars and light trucks, the rotary pump or distributor pump was developed. It uses a single injection cylinder driven from an axial cam plate, which injects into the individual fuel lines via a rotary distribution valve. Later incarnations such as the Bosch VE pump vary the injection timing with crankshaft speed to allow. commer:cement of injection. The single pumping element ensures uniform delivery of fuel to each engine cylinder, and eliminates having to balance the deliveries from each of the high-pressure delivery pipes. WORKING PRINCIPLE.
