otto cycle (Meaning)
otto cycle ()
A four-stroke cycle for internal-combustion engines consisting of the following operations: First stroke, suction into cylinder of explosive charge, as of gas and air; second stroke, compression, ignition, and explosion of this charge; third stroke (the working stroke), expansion of the gases; fourth stroke, expulsion of the products of combustion from the cylinder. This is the cycle invented by Beau de Rochas in 1862 and applied by Dr. Otto in 1877 in the Otto-Crossley gas engine, the first commercially successful internal-combustion engine made.

otto cycle Sentence Examples
- The Otto cycle is a thermodynamic cycle that describes the operation of a gasoline engine.
- The Otto cycle consists of four strokes: intake, compression, power, and exhaust.
- During the intake stroke, the piston moves down and draws in air and fuel into the cylinder.
- During the compression stroke, the piston moves up and compresses the air and fuel mixture.
- During the power stroke, the compressed air and fuel mixture is ignited and burns, driving the piston down.
- During the exhaust stroke, the piston moves up and expels the burned gases from the cylinder.
- The efficiency of an Otto cycle engine is determined by the ratio of the heat added during the combustion process to the heat rejected during the exhaust process.
- The Otto cycle is a relatively inefficient cycle, as it loses a significant amount of heat to the environment.
- However, the Otto cycle is simple and inexpensive to implement, which is why it is used in most gasoline engines.
- Recent advances in engine technology have led to the development of more efficient variations of the Otto cycle, such as the Miller cycle and the Atkinson cycle.
