aircraft engine | the engine that powers and aircraft |
automobile engine | the engine that propels an automobile |
auxiliary engine donkey engine | (nautical) a small engine (as one used on board ships to operate a windlass) |
cooling system engine cooling system | equipment in a motor vehicle that cools the engine |
diesel diesel engine diesel motor | an internalombustion engine that burns heavy oil |
engine | motor that converts thermal energy to mechanical work |
engine | an instrument or machine that is used in warfare, such as a battering ram, catapult, artillery piece, etc., medieval engines of war |
engine block cylinder block block | a metal casting containing the cylinders and cooling ducts of an engine, the engine had to be replaced because the block was cracked |
engineering engine room | a room (as on a ship) in which the engine is located |
externalombustion engine | a heat engine in which ignition occurs outside the chamber (cylinder or turbine) in which heat is converted to mechanical energy |
fanjet fan-jet fanjet engine turbojet turbojet engine turbofan turbofan engine | a jet engine in which a fan driven by a turbine provides extra air to the burner and gives extra thrust |
fire engine fire truck | any of various large trucks that carry firemen and equipment to the site of a fire |
four-stroke engine four-stroke internalombustion engine | an internalombustion engine in which an explosive mixture is drawn into the cylinder on the first stroke and is compressed and ignited on the second stroke, work is done on the third stroke and the products of combustion are exhausted on the fourth stroke |
gas engine | an internalombustion engine similar to a gasoline engine but using natural gas instead of gasoline vapor |
gasoline engine petrol engine | an internalombustion engine that burns gasoline, most automobiles are driven by gasoline engines |
heat engine | any engine that makes use of heat to do work |
internalombustion engine ICE | a heat engine in which combustion occurs inside the engine rather than in a separate furnace, heat expands a gas that either moves a piston or turns a gas turbine |
ion engine | a type of reaction-propulsion engine to propel rockets in space, a stream of positive ions is accelerated to a high velocity by an electric field |
jet engine | a gas turbine produces a stream of hot gas that propels a jet plane by reaction propulsion |
locomotive engine locomotive engine railway locomotive | a wheeled vehicle consisting of a self-propelled engine that is used to draw trains along railway tracks |
pilot engine | a locomotive that precedes a train to check the track |
radial engine rotary engine | an internalombustion engine having cylinders arranged radially around a central crankcase |
ramjet ramjet engine atherodyde athodyd flying drainpipe | a simple type of jet engine, must be launched at high speed |
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) |
engine failure | engine does not run |
engineer locomotive engineer railroad engineer engine driver | the operator of a railway locomotive |
engine | something used to achieve a purpose, an engine of change |
