Note there is a smaller resolution version also available for embedding. I think an animation of this principle is very useful.
The engine, known as the e-REX creates 4 times more power events per revolution than a conventional 4 Stroke and twice more than a 2 Stroke. [1] Although the e-REX is called a one-stroke engine there is debate that says it is actually a two-stroke engine, it is called a one-stroke because each piston executes two strokes (i.e., compression ...
Animation of a two-stroke engine. 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 in contrast to a four-stroke engine which requires four strokes of the piston in two crankshaft revolutions to complete a power cycle.
The Bajulaz six-stroke engine was invented in 1989 by Roger Bajulaz of the Bajulaz S.A. company, based in Geneva, Switzerland; it has U.S. patent 4,809,511 and U.S. patent 4,513,568. The Bajulaz six-stroke engine features claimed are: Reduction in fuel consumption by at least 40%; Two expansion (work) strokes in six strokes
Animation of the Atkinson differential engine 1932 Junkers Jumo 205 diesel aircraft engine. One of the first opposed-piston engines was the 1882 Atkinson differential engine, [7] which has a power stroke on every rotation of the crankshaft (compared with every second rotation for the contemporary Otto cycle engine), but it was not a commercial success.
In 1879, Nicolaus Otto built a 5-stroke engine which was commercially produced, but suffered from poor performance. [2] Two Spanish patents (ES0156621, F Jimeno-Cataneo, 1942; and ES0433850, C Ubierna-Laciana, 1975) describe 5-stroke engines identical to that of Schmitz's design, this engine had a fellowship to Burgundy University to be studied.
Diagram showing the operation of a 4-stroke SI engine. Labels: 1 ‐ Induction 2 ‐ Compression 3 ‐ Power 4 ‐ Exhaust. The top dead center (TDC) of a piston is the position where it is nearest to the valves; bottom dead center (BDC) is the opposite position where it is furthest from them.
Circa-1960 Saab two-stroke engine 2010 Suzuki K10B engine. Among the first cars to use a straight-three engine is the 1953–1955 DKW F91, powered by a 900 cc (55 cu in) two-stroke engine, although this was predated by the 3 cylinder 15hp Rolls Royce produced in 1905 and a number of other cars of this era also used 3 cylinder engines.
