  2. Internal combustion engine cooling - Wikipedia

    en.wikipedia.org/wiki/Internal_combustion_engine...

    The worst problem met in air-cooled aircraft engines was the so-called "shock cooling", when the airplane entered in a dive after climbing or level flight with throttle open, with the engine under no load while the airplane dives generating less heat, and the flow of air that cools the engine is increased, a catastrophic engine failure may ...

  3. Heater core - Wikipedia

    en.wikipedia.org/wiki/Heater_core

    Since the heater core relies on the coolant's heat to warm the cabin air up, it will not begin working until the engine's coolant warms up enough. This problem can be resolved by equipping the vehicle with an auxiliary heating system, which can either use electricity or burn the vehicle's fuel in order to rapidly bring the engine's coolant to ...

  4. Antifreeze - Wikipedia

    en.wikipedia.org/wiki/Antifreeze

    The term engine coolant is widely used in the automotive industry, which covers its primary function of convective heat transfer for internal combustion engines. When used in an automotive context, corrosion inhibitors are added to help protect vehicles' radiators , which often contain a range of electrochemically incompatible metals ( aluminum ...

  5. Head gasket - Wikipedia

    en.wikipedia.org/wiki/Head_gasket

    If the combustion gases are leaking into the cooling system, this reduces the effectiveness of the cooling system and can cause the engine to overheat. In other occurrences the gases can leak into small spaces between the gasket and either the cylinder head or engine block traps those gases, and then released when the engine is turned off.

  6. Radiator (engine cooling) - Wikipedia

    en.wikipedia.org/wiki/Radiator_(engine_cooling)

    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.

  7. Waterless coolant - Wikipedia

    en.wikipedia.org/wiki/Waterless_coolant

    Waterless coolant is most prominently used in the cooling systems for motorsports, classic car, ATVs, UTVs, snowmobiles and older cars. [4] Older cars often have non-pressurized cooling systems, and the water-based coolant can boil and overflow. Traditionally, this issue has been solved by topping off the radiator with water. This dilutes the ...

  8. Coolant - Wikipedia

    en.wikipedia.org/wiki/Coolant

    A coolant is a substance, typically liquid, that is used to reduce or regulate the temperature of a system. An ideal coolant has high thermal capacity, low viscosity, is low-cost, non-toxic, chemically inert and neither causes nor promotes corrosion of the cooling system. Some applications also require the coolant to be an electrical insulator.

  9. Cold start (automotive) - Wikipedia

    en.wikipedia.org/wiki/Cold_start_(automotive)

    Generally speaking, diesel engines have more difficulty starting at low outside temperatures than gasoline engines, and electric engines have the most problems. Diesel engines do not use spark plugs to ignite the air fuel mixture and rely only on the heat generated by compression alone to ignite the fuel.
