2. Antifreeze - Wikipedia

   en.wikipedia.org/wiki/Antifreeze

   An antifreeze mixture is used to achieve freezing-point depression for cold environments. Common antifreezes also increase the boiling point of the liquid, allowing higher coolant temperature. [1] However, all common antifreeze additives also have lower heat capacities than water, and do reduce water's ability to act as a coolant when added to ...

3. Internal combustion engine cooling - Wikipedia

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

   Most liquid-cooled engines use a mixture of water and chemicals such as antifreeze, rust inhibitors, and other additives. These antifreeze mixtures, also known as "engine coolant," are typically glycol-based fluids that contain a mixture of ethylene glycol, additives, and water. Common types of coolants include Inorganic Acid Technology (IAT ...

4. Coolant - Wikipedia

   en.wikipedia.org/wiki/Coolant

   Carbon Dioxide (chemical formula is CO 2) - is used as a coolant replacement [5] for cutting fluids. CO 2 can provide controlled cooling at the cutting interface such that the cutting tool and the workpiece are held at ambient temperatures. The use of CO 2 greatly extends tool life, and on most materials allows the operation to run faster. This ...

   CH 2 FCF 3: 1,1,1,2-Tetrafluoroethane: 3790 1550 Widely used Most used in 2020 for hydronic heat pumps in Europe and the United States in spite of high GWP. [58] Commonly used in automotive air conditioners prior to phase out which began in 2012. R-410A: 50% R-32 / 50% R-125 (pentafluoroethane) Between 2430 (R-32) and 6350 (R-125) > 677: Widely ...

6. 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. It is an odorless, colorless, flammable, viscous liquid.

7. Matchless G12 - Wikipedia

   en.wikipedia.org/wiki/Matchless_G12

   The Matchless G12 was one of the last motorcycles designed under the Matchless name. It was also produced as the AJS Model 31 by the same company. [2] Designed by Phil Walker, AMC knew that it had to be a 650 cc (39.7 cu in) but wanted to use as many parts from the Model 11 as possible.
