(internal combustion engines) Fuel injection: the pressurized introduction of fuel into a cylinder.
n
Part of an engine that supplies the fuel/air mixture to the cylinder.
n
(automotive) The subsystem of an engine that takes in air from the environment and delivers it to the combustion chamber
n
The process where fuel is burned within an engine such as a diesel engine, producing power directly as opposed to externally such as in a steam engine.
adj
Alternative form of internal combustion engined [Having an internal combustion engine.]
v
To adjust the fuel to air ratio of a carburetor; to install or adjust a carburetor jet
n
Alternative form of jet pipe [(especially aviation) A pipe at the back of a gas turbine out of which exhaust gases are discharged]
n
small-scale hydroelectric power that exploits the natural flow of water
n
(automotive, informal) The system in some racing vehicles which pumps nitrous oxide into the engine to improve performance.
n
A vertical steam engine in which the cylinder stands above the crank.
n
Alternative spelling of pump-jet [(nautical) A marine system that creates a jet of water for propulsion; a water jet]
n
A central jet that protrudes from the centre of the "crater" formed by a drop landing on the surface of a fluid.
n
(aeronautics, chiefly Britain) An afterburner.
adj
(of a pump) In which energy is continuously imparted to the pumped fluid by means of a rotating impeller, propeller, or rotor (unlike a positive displacement pump, in which a fluid is moved by trapping a fixed amount of fluid and forcing the trapped volume into the pump's discharge)
n
The muffler of an internal combustion engine.
n
The sound produced, in an internal combustion engine, by the ignition of the fuel-air mixture before the piston reaches top dead centre
n
The part of an internal combustion engine which forms a high-voltage electric spark which ignites the fuel-air mixture to begin the power stroke.
n
A hand lever for working the valves when starting a steam engine.
n
A once common but now obsolete type of crane powered by a steam engine, with the steam usually supplied from a vertical boiler.
n
A piston engine driven by steam (as contrasted, for example, with a steam turbine).
n
A system of angled and shaped blades arranged on a rotor through which steam is passed to generate rotational energy. Today, normally used in power stations.
n
A vertical back-acting steam engine having the cylinder beneath the crosshead.
v
(automotive) To increase the power of an internal combustion engine (either Otto or Diesel cycle) by compressing the inlet air with power extracted from the crankshaft.
n
(automotive, internal combustion engines) An inlet air compressor for an internal combustion engine (either Otto or Diesel cycle).
v
(aviation) To carry more fuel than necessary for a flight, in order to avoid having to refuel at a destination where fuel is more expensive or in short supply.
n
A valve that regulates the supply of fuel-air mixture to an internal combustion engine and thus controls its speed; a similar valve that controls the air supply to an engine.
n
A part of the air intake system of a fuel injected engine, responsible for regulating the airflow into the engine.
n
A type of high-performance intake manifold designed to straighten the pathway of fuel/air mixture, speeding the flow to the combustion chambers.

n
A device that turns a laminar flow into a turbulent flow.
n
The fuel used in a two-stroke engine.

(of an engine) In which the gas mixture enters at one end of the cylinder controlled by the piston and the exhaust exits at the other.
n
A device that admits fuel and air into the cylinder of an internal combustion engine, or one that allows combustion gases to exit.
n
(mechanical engineering) A problem mostly affecting gasoline-fueled internal combustion engines, where the liquid fuel changes state from liquid to gas while still in the fuel delivery system, reducing the pump pressure and causing transient power loss or complete stalling.
n
(mechanical engineering, automotive, aviation) A valve that allows exhaust gases to bypass an engine's turbocharger, in order to keep from overspeeding the turbocharger rotor or driving the boost pressure high enough to risk engine knocking or detonation.
n
(countable) A site capable of generating power or the right to use a site to generate power.
