  2. Corrosion inhibitor - Wikipedia

    en.wikipedia.org/wiki/Corrosion_inhibitor

    A corrosion inhibitor or anti-corrosive is a chemical compound added to a liquid or gas to decrease the corrosion rate of a metal that comes into contact with the fluid. [1] The effectiveness of a corrosion inhibitor depends on fluid composition and dynamics .

  3. Antifreeze - Wikipedia

    en.wikipedia.org/wiki/Antifreeze

    Most commercial antifreeze formulations include corrosion inhibiting compounds, and a colored dye (commonly a fluorescent green, red, orange, yellow, or blue) to aid in identification. [21] A 1:1 dilution with water is usually used, resulting in a freezing point of about −34 °F (−37 °C), depending on the formulation. In warmer or colder ...

  4. Internal combustion engine cooling - Wikipedia

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

    The first engines relied on thermosiphon cooling alone, where hot coolant left the top of the engine block and passed to the radiator, where it was cooled before returning to the bottom of the engine. Circulation was powered by convection alone. Other demands include cost, weight, reliability, and durability of the cooling system itself.

  5. Ethylene glycol - Wikipedia

    en.wikipedia.org/wiki/Ethylene_glycol

    Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound (a vicinal diol [7]) with the formula (CH 2 OH) 2.It is mainly used for two purposes: as a raw material in the manufacture of polyester fibers and for antifreeze formulations.

  6. Core plug - Wikipedia

    en.wikipedia.org/wiki/Core_plug

    Core plugs can often be a source of leaks due to corrosion caused by cooling system water. [4] Although modern antifreeze chemicals do not evaporate and may be considered "permanent", anti-corrosion additives gradually deplete and must be replenished via a flush and refill. Automotive manufacturers specify time and mileage numbers for cooling ...

  7. 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.

  8. Water cooling - Wikipedia

    en.wikipedia.org/wiki/Water_cooling

    Water is inexpensive, non-toxic, and available over most of the earth's surface.Liquid cooling offers higher thermal conductivity than air cooling. Water has unusually high specific heat capacity among commonly available liquids at room temperature and atmospheric pressure allowing efficient heat transfer over distance with low rates of mass transfer.

  9. Cutting fluid - Wikipedia

    en.wikipedia.org/wiki/Cutting_fluid

    The official technique to measure oil concentration in cutting fluid samples is manual titration: [4] 100ml of the fluid under test is titrated with a 0.5M HCl solution to an endpoint of pH 4 and the volume of titrant used to reach the endpoint is used to calculate the oil concentration. This technique is accurate and not affected by fluid ...
