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 ...
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 ...
In 2015, South Korea had made it mandatory for diesel cars to use urea solutions to control emissions, a move that now impacts 40% of registered vehicles. Diesel vehicles made since 2015 were required to be fitted with SCR systems. [ 28 ]
OWI sponsored the fall Sprint Cup Series event at Dover International Speedway from 1989 to 1992 as the PEAK Antifreeze 500 and from 1993 to 1994 as the SplitFire Spark Plug 500. It began sponsoring NASCAR's online iRacing.com series in 2009, becoming the title sponsor in 2014 for what is now the NASCAR Peak Antifreeze Series.
Common absorption refrigerators use a refrigerant with a very low boiling point (less than −18 °C (0 °F)) just like compressor refrigerators.Compression refrigerators typically use an HCFC or HFC, while absorption refrigerators typically use ammonia or water and need at least a second fluid able to absorb the coolant, the absorbent, respectively water (for ammonia) or brine (for water).
Advantages of a truck conversion over a standard Class A are safety, ease of service/maintenance, and usually a much higher power-to-weight ratio, since most semi-tractors are built to move an 80,000-pound (36,000 kg) combined weight. A disadvantage is that with the engine up front, they are louder than when the engine is in the back.

(The −50 °F (−46 °C) commercial product is 40:60.) Pink dye is used to imply that it is not toxic. Normal antifreeze (an ethylene glycol and water mixture) is colored green or blue to show that it is a toxic chemical. Refrigerator Most RV refrigerators are "absorption cycle", rather than "compressor cycle" appliances (Also see RV Fridge ...
