Helix-type injector pump The injector pump is operated by a cam which drives the plunger up and down. The timing of the injection can be altered by raising or lowering

Fuel oil system The fuel oil system for a diesel engine can be considered in two parts – the fuel supply and the fuel injection systems. Fuel supply deals with

Efficient scavenging is essential to ensure a sufficient supply of fresh air for combustion. In the four-stroke cycle engine there is an adequate overlap between the air inlet valve opening

Two-stroke cycle The two-stroke cycle is completed in two strokes of the piston or one revolution of the crankshaft. In order to operate this cycle where each event is accomplished

Four-stroke cycle The four-stroke cycle is completed in four strokes of the piston, or two revolutions of the crankshaft. In order to operate this cycle the engine requires a mechanism

MAINTAINENCE OF HEAT EXCHANGERS The only attention that heat exchangers should require is to ensure that the heat transfer surfaces remain substantially clean and flow passages generally clear of obstruction.

Shell and tube heat exchangers for engine cooling water and lubricating oil cooling have traditionally been circulated with sea water. The sea water is in contact with the inside of

The obvious feature of plate type heat exchangers, is that they are easily opened for cleaning. The major advantage over tube type coolers, is that their higher efficiency is reflected

The common rail system has one high-pressure multiple plunger fuel pump.The fuel is discharged into a manifold or rail which is maintained at high pressure. From this common rail fuel

  In the variable injection timing (VIT) pump used in MAN B&W engines the governor output shaft is the controlling parameter. Two linkages are actuated by the regulating shaft of
