Some engine controls shut down an engine or limit it to half throttle if it overheats. Modern electronic engine controls adjust cooling based on throttle to anticipate a temperature rise, and limit engine power output to compensate for finite cooling. Finally, other concerns may dominate cooling system design.
A typical engine coolant radiator used in an automobile. 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.
It was originally intended to keep the engine running a preset amount of time as to let the engine cool, and prevent carbon buildup. Eventually HKS developed the turbo timer more, including features such as adjustable timing, multiple different time presets, the ability to monitor voltage, as well as a combined security system as well.

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.
Car engine wax thermostatic element. The wax thermostatic element was invented in 1934 by Sergius Vernet (1899–1968). [1] Its principal application is in automotive thermostats used in the engine cooling system. The first applications in the plumbing and heating industries were in Sweden (1970) and in Switzerland (1971).
In a turbojet, turbofan or turboprop engine, a great amount of the air ingested by the engine runs around the combustion chamber or around its flame, instead of being mixed with fuel and burned. The purpose of this air is to cool the combustion chambers and keep the temperature of the chamber within its limits.

Waterless coolant lasts the life of the engine, and there is no need to have that system pressurized, which has shown to reduce stress on the cooling system plumbing. [6] Waterless coolant has been used to reduce fuel usage by limiting the amount of time the radiator fan needs to be on.
