Sažetak

The paper analyses fuel supply systems in modern marine diesel engines where engine operation is controlled electronically. The basic elements of fuel supply system in MAN-B&W marine engine are analyzed. Unlike traditional method of engine operation by camshaft. MAN-B&W company has developed the system of electronic operation of working process, the main task being the control of fuel injection, opening and closing of exhaust valves and cylinder lubrication. Electronically controlled MAN-B&W engine is based on separately driven fuel injection pump and exhaust valves so that exhaust valve lifters and oil fuel atomizers are controlled electronically by means of a definite numbers of control units making together “engine control system”.
Besides the analysis of fuel supply system in MAN-B&W engine, common fuel oil supply in Wartsila engines, so called Common rail system, which is also used in Sulzer RT-flex engines, has been presented. Finally traditional and electronic engine operation have been compared.
