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 ...

Note there is a smaller resolution version also available for embedding. I think an animation of this principle is very useful.
A typical desaxe engine will have strokes of 185° - 175° - 185° - 175°, etc., with the differential roughly (but not directly) proportional to the percentage of offset distance to stroke length. The relative proportion of offset distance versus stroke length ranges from very small to almost 20%; viz. an engine with an 80 mm stroke may have ...
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.
The Bourke engine was an attempt by Russell Bourke, in the 1920s, to improve the two-stroke internal combustion engine. Despite finishing his design and building several working engines, the onset of World War II , lack of test results, [ 1 ] and the poor health of his wife compounded to prevent his engine from ever coming successfully to market.

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.
It had a total engine capacity of 71.5 L (4,360 cu in), and a high power-to-weight ratio. The largest reciprocating engine in production at present, but not the largest ever built, is the Wärtsilä-Sulzer RTA96-C turbocharged two-stroke diesel engine of 2006 built by Wärtsilä.
