FUEL SUPPLY SYSTEMS OF THE DIESEL ENGINES

Da bi se motor mogao pokrenuti potreban je sustav za ubrizgavanje goriva čiji su glavni sastavni dijelovi visokotlačna pumpa za ubrizgavanje goriva, visokotlačni cjevovodi i brizgaljke. U ovom radu analizirat će se sustavi za napajanje goriva Diesel motora. Definiran je princip rada triju pumpi te je dan proračun za pumpu s radijalnim klipovima. Isto tako analizirana su tri sustava za ubrizgavanje i proračun za rad sustava pumpa-brizgaljka (PDE sustav).In order for the engine to start, a fuel injection system is required, the main components of which are a high-pressure fuel injection pump, high-pressure pipes and injectors. This paper describes Diesel engine fuel supply systems. The principle of operation of the three pumps is described and a calculation is given for a pump with radial pistons. Also described are three injection systems and a calculation for the operation of a pump-injector system (PDE system)
