In January 1976, Inficon was acquired by Leybold-Heraeus GmbH a vacuum technology company. Due to this acquisition, Inficon became known as Inficon Leybold-Heraeus. [8] [9] In 1987, Leybold-Heraeus GmbH, the parent company of Inficon, was purchased by Degussa AG, and the name was changed to Leybold AG. At this point, Inficon Leybold-Heraeus ...
The shaft of the four-stroke piston rotates twice as fast as the shaft of the two-stroke piston, and the two-stroke part always runs at half speed. This ensures that both parts work optimally regarding fuel consumption at all times. The same principles apply to having two distinct engines, but the design of the M4+2 is much simpler.

Later Cuyuna formed a subsidiary Two Stroke International, commonly known as 2si, to produce and market the engine line. Cuyuna ended selling engines for aircraft use, but instead switched to marketing them only for industrial, marine, auto racing , kart and all-terrain vehicle applications.
By 1939, several two-stroke diesel types were in widespread use, and others were being developed for high-power applications,. [11] Of several two-stroke aircraft diesel engine concepts, the Junkers Jumo 205 was the only type to be made in significant quantities, with approximately 900 units in all. [12]
Uniflow diesel engine, a two-stroke diesel engine with inlet through piston-ported fixed ports in the lower part of the cylinder, and exhaust through valves in the cylinder head. Opposed-piston diesel engines, where two cylinders share opposite ends of the same cylinder. These use piston-controlled ports for both inlet and exhaust.
Subsequent evolutions of the early designs included the two-cylinder, two-stroke Rotax 377, Rotax 447, and Rotax 503, all in production by 1985 [11] (the last of these, the 503, was discontinued in 2010-2011, by then the most popular engine it its class, and still widely used as of 2023). [14]
The Gen IV LS9 is a supercharged 6,162 cc (6.2 L; 376.0 cu in) engine, based on the LS3; the LS7 block was not used because of the higher cylinder pressures created by the supercharger requiring the thicker cylinder walls of the LS3. It has a bore and stroke of 103.25 mm × 92 mm (4.065 in × 3.622 in).
