Diagnostics and Repair of ship's Engine to Achieve Optimization

Da bi se što kvalitetnije razumjela tema ovog diplomskog rada, u teorijskom dijelu detaljnije su objašnjeni toplinski strojevi, četverotaktni i dvotaktni motor, motorna i plinovita goriva, proces ubrizgavanja goriva kod Dieselovog motora. Cilj ovog rada je pobliže opisati brzokretni dizelski brodski motor te popravke obavljene na istom. Napravljena je dijagnostika havariranog motora. Izvršena su potrebna mjerenja te nakon definiranja potrebnih popravaka odredili su se zamjenski dijelovi. Obrađen je postupak rastavljanja i montaže motora uz kontrolna mjerenja i optimizaciju.For better understanding the topic of this thesis, the theoretical part provides more detailed explanations of thermal machines, 4-stroke and 2-stroke engines, oil and gas fuels, the fuel injection process of Diesel engine. The main goal of this topic is to describe, high-speed marine Diesel engine and repairs done on it, better. Diagnostics of braked down engine was done. The necessary measurements were made and after the finding the needed repairs new parts were installed. Procedure of disassembly and assembly of the engine was done together with control measurements and optimization
