Design and analysis of fuel injection system for two stroke diesel engine

Cilj ovoga rada jest opisati glavne dijelove sustava za ubrizgavanje goriva, princip rada pojedinih dijelova kao što su ubrizgavači i visokotlačne pumpe, te sustav zajedničkog voda koji se danas najčešće upotrebljava kod dizelskih motora. U ovom radu opisan je princip rada dvotaktnih sporohodnih motora. Navedene su karakteristike pojedinih tipova goriva koja se koriste kod eksploatacije broda, te njihov sustav na brodu od ukrcaja goriva na brod do glavnih motora, te je izvedena analiza sustava za ubrizgavanje goriva. Također opisan je princip rada motora na dvojno gorivo (dizel-plin) koji se danas sve češće koriste jer takvi motori imaju smanjenu emisiju štetnih ispušnih plinova.The purpose of this paper is to explain the working principle and main components of fuel injection system such as: fuel injectors, high pressure pumps and common rail system that is frequently used within diesel engines. Working principle of two stroke slow motion diesel engines is also explained. Characteristics of fuel types that are used during ships voyage are listed and fuel system intake aboard ships that leads to the main engines, also an analysis of fuel injection is performed. Dual fuel engines are explained (diesel-gas) since they are most commonly used for their acceptable of exhaust gases emissions
