The function of the oil pump is to supply oil under pressure to the varies engine parts to be lubricated. 4. The different types of oil pumps used for engine lubrication are as follows, Gear pump; Rotor pump; Plunger pump; Vane pump; 1. Vibration Damper 8. Engine lifting bracket 2. As the 2 stroke engine animation below shows, a two-stroke engine in its purest form is extremely simple in construction and operation, as it only has three primary moving parts (the piston, connecting rod, and crankshaft). Front View (ISC, QSC8.3, ISL, and QSL9) 1. Any oil can either be single-grade, with a set viscosity level, or multi-grade in which the oil can act at two different viscosities depending on its temperature. Crankcase breather 3. Oil is accumulated and stored in the engine's oil pan where one or more oil pumps take a suction and pump the oil through one or more oil filters as shown in Figure 12. Engine oil pan drain plug Engine Diagrams Page 1 of 21 Oil galleries – passages for oil to flow to various engine parts. Oil cooler – cools motor oil to reduce oxidation. The latter is most prevalent today, to cater for vehicles used all year round in various conditions. By pitching down and not touching the engine controls, the engine will start to speed up, and the flyweights will fly outward, due to centrifugal force. The flow of oil to the moving parts is accomplished by the engine's internal lubricating system. Air intake connection 4. State the purpose and describe the operation of the lubrication oil keep warm and pre-lube system(s) as are commonly used on nuclear plant diesel engines. The oil pump is typically placed inside the crankcase below the oil level. NOTE: The illustrations are only a reference to show a typical engine. The indicator is connected electrically to an oil pressure switch or “sending unit”. Front gear cover 6. Oliver and his little oil friends get jammed in together even closer. The gerotor oil pump then pumps the oil back out through the outlet passage in the front cover. Starter 9. The oil separates into two paths. Not all … Lubricating oil system: Lubricating oil for an engine is stored in the bottom of the crankcase, known as the sump, or in a drain tank located beneath the engine .The oil is drawn from this tank through a strainer, one of a pair of pumps, into one of a pair of fine filters. Also included are additional oil passages for the 2007-and-newer (2006-and-newer Dyna) engines with large camshaft journals. One flow path sends oil into the high-pressure pump reservoir initial fill gallery (integral to the cylinder block) and through the anti-drainback check ball. Gear Pump Fan pulley 7. As soon as that happens, the pilot valve will raise, oil will flow into the prop hub, and the pitch of the blades will increase, slowing the engine … Pickup tube: When the engine is switched on, it needs oil immediately. Oil pump: The pump does the sucking so that Oliver can slide up that tube against gravity and then pressurizes the oil. Engine oils are rated by their grade and viscosity. It is then passed through a cooler before entering the engine and being distributed to the various branch pipes. The plates are machined with larger-than-stock, kidney-shaped feed- and scavenge-side oil channels and internal oil galleys for greater oil flow throughout the engine. Oliver and his oil buddies get sucked up by the pickup tube and lined up for action. Engine oil fill 5.
