2. Oil cooling - Wikipedia

   en.wikipedia.org/wiki/Oil_cooling

   Oil cooling is the use of engine oil as a coolant, typically to remove surplus heat from an internal combustion engine. The hot engine transfers heat to the oil which then usually passes through a heat-exchanger, typically a type of radiator known as an oil cooler. The cooled oil flows back into the hot object to cool it continuously.

3. Internal combustion engine cooling - Wikipedia

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

   Only the fixed parts of the engine, such as the block and head, are cooled directly by the main coolant system. Moving parts such as the pistons, and to a lesser extent the crankshaft and connecting rods, must rely on the lubrication oil as a coolant, or to a very limited amount of conduction into the block and thence the main coolant. High ...

4. Radiator (engine cooling) - Wikipedia

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

   Some engines have an oil cooler, a separate small radiator to cool the engine oil. Cars with an automatic transmission often have extra connections to the radiator, allowing the transmission fluid to transfer its heat to the coolant in the radiator. These may be either oil-air radiators, as for a smaller version of the main radiator.

5. 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.

6. Applications of the Stirling engine - Wikipedia

   en.wikipedia.org/wiki/Applications_of_the...

   The free-piston Stirling cooler (FPSC) is a completely sealed heat transfer system that has only two moving parts (a piston and a displacer), and which can use helium as the working fluid. The piston is typically driven by an oscillating magnetic field that is the source of the power needed to drive the refrigeration cycle.

7. Oil additive - Wikipedia

   en.wikipedia.org/wiki/Oil_additive

   Although PTFE has been called "the slickest substance known to man", [15] [16] it would hardly do any good if it remains in the oil filter. Some mass-market engine oil additives, notably the ones containing PTFE/Teflon (e.g. Slick 50) [17] and chlorinated paraffins (e.g. Dura Lube), [18] caused a major backlash by consumers; the U.S. Federal ...
