2.7.7. Circulation of engine oil
Circulation of engine oil
Lubricant of the engine is carried out under pressure. The oil pump takes away oil from the oil pallet via the mesh filter and gives it under pressure via the filter of thin purification of oil. In the oil pump there is perepuskny a valve which supports pressure at one level in the engine lubrication system. If pressure in the lubrication system of the engine increases above a certain level, the valve opens perepuskny and a part of oil flows down back in the oil pallet. Passing through an oil filter, the purified oil comes to the trunk oil main. In the oil highway the oil pressure sensor which, including a control bulb on a combination of devices, signals about the low pressure of oil is installed. In an oil filter there is a valve which in case of strong pollution of an oil filter bypasses the crude oil directly to the oil highway. From the trunk main on channels oil under pressure moves for lubricant of radical bearings of a bent shaft and further via channels in cranked to a shaft to conrod bearings. For cooling of pistons oil through nozzles is sprayed on the lower part of pistons. On channels oil moves to a head of the block of cylinders for lubricant of bearings of camshafts and in hydraulic pushers. Prevention |
