A Yanmar 2GM20 marine diesel engine, installed in a sailboat. The center pulley is the crankshaft, the lower left one the seawater pump, the upper right one the alternator. The Yanmar 2GM20 is a series of inboard marine diesel engines manufactured by the Japanese company Yanmar Co. Ltd. It is used in a wide range of sailboats and motorboats.
The EN 590 had been introduced along with the European emission standards.With each of its revisions the EN 590 had been adapted to lower the sulphur content of diesel fuel – since 2007 this is called ultra-low-sulphur diesel as the former function of sulphur as a lubricant is absent (and needs to be replaced by additives).
1952 Shell Oil film showing the development of the diesel engine from 1877. The diesel engine, named after the German engineer 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 engine is called a compression-ignition engine (CI engine).
In 1969, Ohio Diesel Mechanics School offered one 6-week course with phases in Cummins 4-stroke engine, Detroit 2-stroke engine and basic diesel fundamentals. In 1972, the school’s name changed to Ohio Diesel Technical Institute, and, in 1981, automotive diesel was added to the curriculum. In 1984, an Automotive Technology program was added.
The Navistar DT (Diesel Turbocharged or Diesel Turbo) engine family is a line of mid-range inline-6 diesel engines.With horsepower ratings ranging from 170 hp (130 kW) to 350 hp (260 kW), the Navistar DT engines are used primarily in medium-duty truck and bus applications such as school buses, although some versions have been developed for heavy-duty regional-haul and severe-service applications.
Diesel engines are used in aircraft, automobiles, power generation, diesel–electric locomotives, and both surface ships and submarines. The Diesel cycle is assumed to have constant pressure during the initial part of the combustion phase (to in the diagram, below). This is an idealized mathematical model: real physical diesels do have an ...

Block of a modern V6 diesel engine. The large holes are the cylinders, the small round orifices are mounting holes, and the small oval orifices adjacent to the cylinders are coolant or oil ducts. In an internal combustion engine, the engine block is the structure that contains the cylinders and other components.
