WebBy the late 1950s, a majority of commercial ships were propelled by diesel engines fired by residual fuels, or so-called HFOs. Until the Middle Eastern oil embargoes of the early and mid-1970s, the consistency and quality of these vintage heavy fuels were, by all accounts, reasonable and predictable. The first diesel engines for ships were made by A. B. Diesels Motorer Stockholm in 1903. These engines were three-cylinder units of 120 PS (88 kW) and four-cylinder units of 180 PS (132 kW) and used for Russian ships. In World War I, especially submarine diesel engine development advanced quickly. By the … See more The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel … See more Overview The characteristics of a diesel engine are • Use of compression ignition, instead of an ignition apparatus such as a spark plug. • Internal mixture … See more The fuel is injected at high pressure into either the combustion chamber, the "swirl chamber" or the "pre-chamber" (unlike older petrol engines … See more Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation, "EGR").
