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 diesel 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.
It is a mechanically injected two-stroke diesel engine that used a Roots blower. The 16-184A was installed in some 110-foot (34 m) subchasers of the SC-497 class during World War II. The two 1,540 bhp (1,150 kW) 16-184A diesel engines driving two shafts produced a faster subchaser that achieved 21 knots. [67]
The pulse-and-glide strategy is proven to be an efficient control design in both car-following [26] and free-driving scenarios, [28] with up to 20% fuel saving. In the PnG strategy, the control of the engine and the transmission determines the fuel-saving performance, and it is obtained by solving an optimal control problem (OCP).
Southern Pacific 9010 is a KM ML 4000 C'C' diesel-hydraulic locomotive, built in 1964 by German manufacturer Krauss-Maffei for the Southern Pacific Railroad. SP 9010 generated 4,000 horsepower (3,000 kW) from two 2,000-horsepower (1,500 kW) V16 Maybach MD870 diesel engines.
However, a real diesel engine will be more efficient overall since it will have the ability to operate at higher compression ratios. If a petrol engine were to have the same compression ratio, then knocking (self-ignition) would occur and this would severely reduce the efficiency, whereas in a diesel engine, the self ignition is the desired ...

In 2022, the MAN 49/60 four-stroke engine series was introduced to the market. These engines are capable of running on LNG, diesel, HFO, and sustainable fuels in both gas and diesel modes. [33] In 2023, the company conducted trials using carbon-free ammonia as fuel with a two-stroke diesel engine.
