Motor oil Wikipedia. Motor oil, engine oil, or engine lubricant is any of various substances comprising base oils enhanced with additives, particularly antiwear additive plus detergents, dispersants and, for multi grade oils viscosity index improvers. In addition to that, almost all lubricating oils contain corrosion GB rust and oxidation inhibitors. Motor oil is used for lubrication of internal combustion engines. The main function of motor oil is to reduce friction and wear on moving parts and to clean the engine from sludge one of the functions of dispersants and varnish detergents. It also neutralizes acids that originate from fuel and from oxidation of the lubricant detergents, improves sealing of piston rings, and cools the engine by carrying heat away from moving parts. Motor oils today are blended using base oils composed of petroleum basedhydrocarbons, that means organic compounds consisting of carbon and hydrogen, or polyalphaolefins PAO or their mixtures in various proportions, sometimes with up to 2. Air Force Oil Filled Radiator Manual Lawn' title='Air Force Oil Filled Radiator Manual Lawn' />HistoryeditOn September 6, 1. American John Ellis founded the Continuous Oil Refining Company Later to become Valvoline. While studying the possible healing powers of crude oil, Dr. Ellis was disappointed to find no real medicinal value, but was intrigued by its potential lubricating properties. He eventually abandoned the medical practice to devote his time to the development of an all petroleum, high viscosity lubricant for steam engines then using inefficient combinations of petroleum and animal and vegetable fats. He made his breakthrough when he developed an oil that worked effectively in high temperatures. This meant no more gummed valves, corroded cylinders or leaking seals. In 1. 87. 3 Ellis officially renamed the company to Valvoline after the steam engine valves that the product lubricated. Motor oil is a lubricant used in internal combustion engines, which power cars, motorcycles, lawnmowers, engine generators, and many other machines. Motor oil, engine oil, or engine lubricant is any of various substances comprising base oils enhanced with additives, particularly antiwear additive plus detergents. I/41uGlqwCb9L._AA400.jpg' alt='Air Force Oil Filled Radiator Manual Lawn' title='Air Force Oil Filled Radiator Manual Lawn' />In engines, there are parts which move against each other, and the friction wastes otherwise useful power by converting the kinetic energy to heat. It also wears away those parts, which could lead to lower efficiency and degradation of the engine. EHow Auto gets you on the fast track with repair, maintenance, and shopping advice. Whether youre jump starting a battery or insuring a new car, we can help. This increases fuel consumption, decreases power output, and can lead to engine failure. Lubricating oil creates a separating film between surfaces of adjacent moving parts to minimize direct contact between them, decreasing heat caused by friction and reducing wear, thus protecting the engine. In use, motor oil transfers heat through convection as it flows through the engine by means of air flow over the surface of the oil pan, an oil cooler and through the buildup of oil gases evacuated by the Positive Crankcase Ventilation PCV system. In petrol gasoline engines, the top piston ring can expose the motor oil to temperatures of 1. C 3. 20 F. In diesel engines the top ring can expose the oil to temperatures over 3. C 6. 00 F. Motor oils with higher viscosity indices thin less at these higher temperatures. Coating metal parts with oil also keeps them from being exposed to oxygen, inhibiting oxidation at elevated operating temperatures preventing rust or corrosion.

Ranger Hope 2015. Corrosion inhibitors may also be added to the motor oil. Many motor oils also have detergents and dispersants added to help keep the engine clean and minimize oil sludge build up. The oil is able to trap soot from combustion in itself, rather than leaving it deposited on the internal surfaces.

Premier League Sleeve Patch here. Rubbing of metal engine parts inevitably produces some microscopic metallic particles from the wearing of the surfaces. Such particles could circulate in the oil and grind against moving parts, causing wear. Because particles accumulate in the oil, it is typically circulated through an oil filter to remove harmful particles. An oil pump, a vane or gear pump powered by the engine, pumps the oil throughout the engine, including the oil filter. Oil filters can be a full flow or bypass type. In the crankcase of a vehicle engine, motor oil lubricates rotating or sliding surfaces between the crankshaftjournal bearings main bearings and big end bearings, and rods connecting the pistons to the crankshaft. The oil collects in an oil pan, or sump, at the bottom of the crankcase. In some small engines such as lawn mower engines, dippers on the bottoms of connecting rods dip into the oil at the bottom and splash it around the crankcase as needed to lubricate parts inside. In modern vehicle engines, the oil pump takes oil from the oil pan and sends it through the oil filter into oil galleries, from which the oil lubricates the main bearings holding the crankshaft up at the main journals and camshaft bearings operating the valves. In typical modern vehicles, oil pressure fed from the oil galleries to the main bearings enters holes in the main journals of the crankshaft. From these holes in the main journals, the oil moves through passageways inside the crankshaft to exit holes in the rod journals to lubricate the rod bearings and connecting rods. Some simpler designs relied on these rapidly moving parts to splash and lubricate the contacting surfaces between the piston rings and interior surfaces of the cylinders. However, in modern designs, there are also passageways through the rods which carry oil from the rod bearings to the rod piston connections and lubricate the contacting surfaces between the piston rings and interior surfaces of the cylinders. This oil film also serves as a seal between the piston rings and cylinder walls to separate the combustion chamber in the cylinder head from the crankcase. The oil then drips back down into the oil pan. Motor oil may also serve as a cooling agent. In some constructions oil is sprayed through a nozzle inside the crankcase onto the piston to provide cooling of specific parts that undergo high temperature strain. On the other hand, the thermal capacity of the oil pool has to be filled, i. This typically takes longer than heating the main cooling agent  water or mixtures thereof  up to its operating temperature. In order to inform the driver about the oil temperature, some older and most high performance or racing engines feature an oil thermometer. Non vehicle motor oilseditAn example is lubricating oil for four stroke or four cycle internal combustion engines such as those used in portable electricity generators and walk behind lawn mowers. Another example is two stroke oil for lubrication of two stroke or two cycle internal combustion engines found in snow blowers, chain saws, model air planes, gasoline powered gardening equipment like hedge trimmers, leaf blowers and soil cultivators. Often, these motors are not exposed to as wide service temperature ranges as in vehicles, so these oils may be single viscosity oils. In small two stroke engines, the oil may be pre mixed with the gasoline or fuel, often in a rich gasoline oil ratio of 2. Larger two stroke engines used in boats and motorcycles may have a more economical oil injection system rather than oil pre mixed into the gasoline. The oil injection system is not used on small engines used in applications like snowblowers and trolling motors as the oil injection system is too expensive for small engines and would take up too much room on the equipment.
