2.7.7. Кругооборот engine oil

Кругооборот engine oil

1 – the channel of giving of oil in a head of the block of cylinders,
2 – a basic oil highway,
3 – dispersion of oil for cooling of pistons,
4 – an oil stream in the oil filter,
5 – the oil heat exchanger

Engine greasing is carried out under pressure. The oil pump takes away oil from the oil pallet through the mesh filter and submits it under pressure through the filter of thin clearing of oil. In the oil pump is available перепускной the valve which supports pressure at one level in system of greasing of the engine. If pressure in system of greasing of the engine raises above certain level, opens перепускной the valve and an oil part flows down back in the oil pallet.

Passing through the oil filter, the cleared oil arrives in the main oil highway. In an oil highway the gauge of pressure of oil which, including a control bulb on a combination of devices, signals about low pressure of oil is established. In the oil filter there is a valve, which in case of strong pollution of the oil filter перепускает crude oil directly in an oil highway.

From the trunk main on channels oil under pressure moves for greasing of radical bearings of a cranked shaft and further through channels in cranked to a shaft to шатунным to bearings. For cooling of pistons oil through atomizers is sprayed on the bottom part of pistons.

On channels oil moves to a head of the block of cylinders for greasing of bearings of camshafts and in hydraulic pushers.

The oil expense

The oil expense is the quantity of oil necessary for maintenance of process of combustion fuel-air of a mix. Oil losses do not concern the category of the expense of oil in connection with негерметичностью systems of greasing of the engine. The oil expense also defines heats and the pressure which are present at work of the engine. The oil expense is influenced also by service conditions of the car and a driving manner. The maximum expense of oil is 1 l on 1000 km of run of the car.

The prevention

Do not fill in engine oil above a label max on щупе, otherwise not burnt down oil can get to an exhaust system and damage the catalyst.
