The following table takes values as an example for the specific fuel consumption of several types of engines. For specific engines values can and often do differ from the table values shown below. Energy efficiency is based on a lower heating value of 42.7 MJ/kg (84.3 g/(kW⋅h)) for diesel fuel and jet fuel , 43.9 MJ/kg (82 g/(kW⋅h)) for ...
For the mathematical concept, see Cyclic permutation. A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes of the piston (one up and one down movement) in one revolution of the crankshaft. A four-stroke engine requires four strokes of the piston to complete a power cycle ...
A two-stroke diesel engine is a diesel engine that uses compression ignition in a two-stroke combustion cycle. It was invented by Hugo Güldner in 1899. [ 1] In compression ignition, air is first compressed and heated; fuel is then injected into the cylinder, causing it to self-ignite. This delivers a power stroke each time the piston rises and ...
The Detroit Diesel Series 71 is a two-stroke diesel engine series, available in both inline and V configurations, manufactured by Detroit Diesel. The number 71 refers to the nominal displacement per cylinder in cubic inches, a rounding off of 70.93 cu in (1.2 L). Inline models included one, two, three, four and six cylinders, and the V-types ...
Width. 54–64 in (1,371.6–1,625.6 mm) Height. 66–72 in (1,676.4–1,828.8 mm) Dry weight. 8,600–10,860 lb (3,901–4,926 kg) The Detroit Diesel 149 is a series of two-stroke diesel engines manufactured by Detroit Diesel which were first announced in early 1966. After Detroit Diesel was spun off in 1988 and later acquired by MTU ...
The B5204T3[ 79] is a 2.0 L (1,984 cc) straight-five. Bore is 81 mm (3.2 in) and stroke is 77 mm (3.0 in) with a compression ratio of 8.4:1. It is turbocharged and intercooled with a power output of 225 PS (165 kW; 222 hp) at 5700 rpm and 310 N⋅m (229 lb⋅ft) of torque at 2700–5100 rpm.
Wärtsilä-Sulzer RTA96-C. The Wärtsilä RT-flex96C is a two-stroke turbocharged low-speed diesel engine designed by the Finnish manufacturer Wärtsilä. It is designed for large container ships that run on heavy fuel oil. Its largest 14-cylinder version is 13.5 meters high, 26.59 meters long, weighs over 2,300 tonnes, and produces 80.08 ...
In a 2-stroke engine, this is the same as engine RPM. In a 4-stroke engine, this is half the engine RPM. The relationship between advance in degrees and distributor RPM can be drawn as a simple 2-dimensional graph. Lighter weights or heavier springs can be used to reduce the timing advance at lower engine RPM. Heavier weights or lighter springs ...
