Fuel Injection Systems of Marine Large Low Speed Diesel Engines

Abstract

The fuel injection system is one of the most important parts of the diesel engine. In this paper, it reports the history and features of fuel injection systems which were installed on the modem typed marine large two strokes cycle low speed diesel engines. The famous recent three brands have been adopted different typed fuel injection systems on their diesel engines. One is good controllable type, another is simple construction. What did the engineers consider when they developed them?Recently, the fuel injection is controlled by electronic devices. The control ability is increased and we can control not only fuel injection but also fuel oil consumption, NOx emission and smoke. The electronic control fuel injection system removed mechanical devices such as gear train, cam and roller, camshaft, linkage and governor from the diesel engine. This movement is influenced to the exhaust valve driving system, starting air control system and cylinder lubricating system which were moved by the camshaft. The diesel engine will change more from the fuel injection system.
