Internal combustion engine cooling. Internal combustion engine cooling uses either air or liquid to remove the waste heat from an internal combustion engine. For small or special purpose engines, cooling using air from the atmosphere makes for a lightweight and relatively simple system. Watercraft can use water directly from the surrounding ...
Components of jet engines. Diagram of a typical gas turbine jet engine. Air is compressed by the compressor blades as it enters the engine, and it is mixed and burned with fuel in the combustion section. The hot exhaust gases provide forward thrust and turn the turbines which drive the compressor blades. 1.
Air-cooled engine. Air-cooled engines rely on the circulation of air directly over heat dissipation fins or hot areas of the engine to cool them in order to keep the engine within operating temperatures. Air-cooled designs are far simpler than their liquid-cooled counterparts, which require a separate radiator, coolant reservoir, piping and pumps.
Radiator (engine cooling) Radiators are heat exchangers used for cooling internal combustion engines, mainly in automobiles but also in piston-engined aircraft, railway locomotives, motorcycles, stationary generating plants or any similar use of such an engine. Internal combustion engines are often cooled by circulating a liquid called engine ...
The effect was discovered in the 1930s and became more important as the speeds of piston-engined aircraft increased over the next decade. The Meredith effect occurs when air flowing through a duct is heated by a heat-exchanger or radiator containing a hot working fluid. Typically the fluid is a coolant carrying waste heat from an internal ...
Environmental control system. In aeronautics, an environmental control system ( ECS) of an aircraft is an essential component which provides air supply, thermal control and cabin pressurization for the crew and passengers. Additional functions include the cooling of avionics, smoke detection, and fire suppression .
An air cycle machine ( ACM) is the refrigeration unit of the environmental control system (ECS) used in pressurized gas turbine -powered aircraft. Normally an aircraft has two or three of these ACM. Each ACM and its components are often referred as an air conditioning pack. The air cycle cooling process uses air instead of a phase changing ...
Water injection has been used in both reciprocating and turbine aircraft engines. In a reciprocating engine, the use of water injection, also called anti-detonation injection or ADI, is used to prevent engine knocking also known as "detonation". [ 3] Commonly found on large radial engines with pressure carburetors, it is a mixture of water and ...
