Motor oil is a lubricant used in internal combustion engines, which power cars, motorcycles, lawnmowers, engine-generators, and many other machines. In engines, there are parts which move against each other, and the friction between the parts wastes otherwise useful power by converting kinetic energy into heat.
Gear oil is a lubricant made specifically for transmissions, transfer cases, and differentials in automobiles, trucks, and other machinery. It has high viscosity and usually contains organosulfur compounds. Some modern automatic transaxles (integrated transmission and differential) do not use a heavy oil at all but lubricate with the lower ...
In 1909, trials were conducted with W F 436 to see if a solution could be found to reducing the amount of smoke produced by engines passing through the Lyttelton Tunnel. 436 was briefly converted to oil-firing for this purpose, but although the tests were satisfactory, oil was at that time three times more expensive than coal, and so W F 436 ...
Spontaneous combustion or spontaneous ignition is a type of combustion which occurs by self-heating (increase in temperature due to exothermic internal reactions), followed by thermal runaway (self heating which rapidly accelerates to high temperatures) and finally, autoignition. [1] It is distinct from (but has similar practical effects to ...
Satisfactory. Satisfactory is a 2024 factory simulation game created by Swedish video game developer Coffee Stain Studios. It is a 3D first-person open world exploration and factory building game. The player (a "Pioneer") is dropped onto an alien planet with a handful of tools and must exploit the planet's natural resources to construct ...
Total world production of vegetable oil for all purposes in 2005–06 was about 110 million tonnes, with about 34 million tonnes each of palm oil and soybean oil. [86] As of 2018, Indonesia is the world's top supplier of palmoil-based biofuel with annual production of 3.5 million tons, [ 87 ] [ 88 ] and expected to export about 1 million tonnes ...

Abiogenic petroleum origin. The abiogenic petroleum origin hypothesis proposes that most of earth's petroleum and natural gas deposits were formed inorganically, commonly known as abiotic oil. [1] Scientific evidence overwhelmingly supports a biogenic origin for most of the world's petroleum deposits. [2][3] Mainstream theories about the ...
