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, in two crankshaft revolutions.)
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 ...
Yamaha RX 100. The Yamaha RX 100 was a two-stroke motorcycle made by Yamaha from 1985 to 1996 with technical collaboration and distributed in India by the Escorts Group. At the initial stage, Yamaha Japan was exporting all bikes from Japan to India. After 1990, Escorts started production in India, with some parts being imported from Japan.

The Detroit Diesel Series 92 is a two-stroke cycle, V-block diesel engine, produced with versions ranging from six to 16 cylinders. Among these, the most popular were the 6V92 and 8V92, which were V6 and V8 configurations of the same engine respectively. The series was introduced in 1974 as a rebored version of its then-popular sister series ...
Scavenging is the process of replacing the exhaust gas in a cylinder of an internal combustion engine with the fresh air/fuel mixture (or fresh air, in the case of direct-injection engines) for the next cycle. If scavenging is incomplete, the remaining exhaust gases can cause improper combustion for the next cycle, leading to reduced power output.
1939-1960. Number built. More than 125,334. The Pratt & Whitney R-2800 Double Wasp is an American twin-row, 18-cylinder, air-cooled radial aircraft engine with a displacement of 2,800 cu in (46 L), and is part of the long-lived Wasp family of engines. The R-2800 saw widespread use in many important American aircraft during and after World War II.
