external-combustion engine
a heat engine in which ignition occurs outside the chamber (cylinder or turbine) in which heat is converted to mechanical energy
ICE, internal-combustion engine
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
diesel, diesel engine, diesel motor
an internal-combustion engine that burns heavy oil
four-stroke engine, four-stroke internal-combustion engine
an internal-combustion 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 internal-combustion engine similar to a gasoline engine but using natural gas instead of gasoline vapor
gasoline engine, petrol engine
an internal-combustion engine that burns gasoline; most automobiles are driven by gasoline engines
outboard, outboard motor
internal-combustion engine that mounts at stern of small boat
radial engine, rotary engine
an internal-combustion engine having cylinders arranged radially around a central crankcase
reciprocating engine
an internal-combustion engine in which the crankshaft is turned by pistons moving up and down in cylinders
rotary engine
an internal-combustion engine in which power is transmitted directly to rotating components
steam engine
external-combustion 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
valve-in-head engine
internal-combustion engine having both inlet and exhaust valves located in the cylinder head
Type of:
