2. Water injection (engine) - Wikipedia

   en.wikipedia.org/wiki/Water_injection_(engine)

   Adding water increases the mass being accelerated out of the engine, increasing thrust and it also serves to cool the turbines. Since temperature is normally the limiting factor in turbine engine performance at low altitudes, the cooling effect lets the engine run at higher RPM with more fuel injected and more thrust created without overheating ...

3. Internal combustion engine cooling - Wikipedia

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

   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 environment to cool their engines.

6. Component parts of internal combustion engines - Wikipedia

   en.wikipedia.org/wiki/Component_parts_of...

   Large jet engines and gas turbines are started with a compressed air motor that is geared to one of the engine's driveshafts. Compressed air can be supplied from another engine, a unit on the ground or by the aircraft's APU. Small internal combustion engines are often started by pull cords.

7. Hopper cooling - Wikipedia

   en.wikipedia.org/wiki/Hopper_cooling

   Hopper cooling is a simple form of water cooling used for small stationary engines. The defining feature of hopper cooling, amongst other water-cooled engines, is that there is no radiator . Cooling water is heated by the engine and evaporates from the surface of the hopper as steam .
