Marine diesel engines are very similar to the self-ignition engines in heavy-duty vehicles, but they are generally larger, more complex, and operate with higher efficiency. About 75% of all marine diesel engines are four-stroke engines; however, 75% of the installed power is produced by two-stroke engines.

Diesel Fuels in Marine Operations
1954There are a variety of diesel engines Used in marine service, ranging from small life boat and generator engines up to high horsepower, low-speed, main propulsion units having cylinder diameters of 30 in. or more. In a particular ship, moreover, several sizes of engines are generally used, one for propulsion, and others for the various auxiliary uses ...

International Shipbuilding Progress, 1968
In order to calculate exhaust noise spectra (on e.g. bridge wings) a simple mathematical model is given of a large turbo-supercharged marine diesel engine as a source of sound, connected to an exhaust system with or without muffler. The exhaust gas turbines are considered as high internal impedance sound sources.

The axial stiffness of Marine diesel engine crankshafts1
International Shipbuilding Progress, 1967The measurement of the axial stiffnesses of the cranks of four full scale crankshafts, supported by the engine main bearings, is described. The results are discussed and compared with those of the calculations using six published formulae. The relationship between the coefficients and the angles of adjacent cranks, or the “mean” crank angle, is ...
