Unit IV – Combustion and Fuel Injection Systems
Combustion of fuels in IC engines. Preparation of fuels for efficient combustion, Fuel atomization, Requirements for fuel injectors, high pressure pipes and jacketing arrangement, provision of fuel leak off alarms. Design aspect for combustion chambers. Recirculation type and slide type fuel injector, Design aspect of modern injectors, Ignition delay, Injection delay etc. Fuel injection system, Jerk type fuel pump, (Fuel pumps in Sulzer RTA & MAN B&W MC engines), Pump timing of different marine diesel engines. common rail system- Sulzer RT Flex.
Practical: Study of Fuel Pump Construction and Operation, Calibration of Fuel Injection Timing in Diesel Engines Fuel Injector Testing
Activities: Tasks T1. A marine diesel engine shows poor fuel efficiency at sea – analyze combustion and fuel injection system. T2. A ship engine experiences scavenging inefficiency – evaluate system type and suggest improvements. T3. A turbocharged engine shows low power output – diagnose turbocharger and air supply issues. T4. A marine engine faces frequent injector failures – analyze fuel system and recommend solutions.
