reaction-propulsion engine reaction engine | a jet or rocket engine based on a form of aerodynamic propulsion in which the vehicle emits a high-speed stream |
reciprocating engine | an internalombustion engine in which the crankshaft is turned by pistons moving up and down in cylinders |
rocket rocket engine | a jet engine containing its own propellant and driven by reaction propulsion |
rotary engine | an internalombustion engine in which power is transmitted directly to rotating components |
steam engine | externalombustion engine in which heat is used to raise steam which either turns a turbine or forces a piston to move up and down in a cylinder |
switch engine donkey engine | a locomotive for switching rolling stock in a railroad yard |
tank engine tank locomotive | a locomotive that carries its own fuel and water, no tender is needed |
traction engine | steam-powered locomotive for drawing heavy loads along surfaces other than tracks |
valve-in-head engine | internalombustion engine having both inlet and exhaust valves located in the cylinder head |
Wankel engine Wankel rotary engine epitrochoidal engine | a rotary engine that is a four-stroke internalombustion engine without reciprocating parts |
search engine | a computer program that retrieves documents or files or data from a database or from a computer network (especially from the internet) |
cycle of rebirth | (Hinduism) repeated rebirth in new forms |
cycle oscillation | a single complete execution of a periodically repeated phenomenon, a year constitutes a cycle of the seasons |
cardiac cycle | the complete cycle of events in the heart from the beginning of one heart beat to the beginning of the next, an electrical impulse conducted through the heart muscle that constricts the atria which is followed by constriction of the ventricles, the cardiac cycle can be shown on an electrocardiogram |
