Greasing system
Engine oil FE DOHC 1 - the oil pump;
2 - the bypass valve;
3 - the main channel of oil supply;
4 - the gauge of pressure of oil; | 5 - water heat exchanger;
6 - the oil filter;
7 - plug oil sump;
8 - a spray oil. |
The lubrication system includes the oil pan, the oil pump, oil filter and the different channels. The oil pump is driven by the crankshaft. The bypass valve in the oil pump maintains the pressure in the lubrication system of the engine at a predetermined level and when it is exceeded, the bypass valve opens and a portion of the oil flows back to the sump. The filter has a bypass valve through which in the case of heavy contamination of the filter crude oil flows directly into the oil pipe.
Refined oil filter oil enters the main oil highway. Further, the oil flow is divided into two streams. A stream of oil is supplied to the crankshaft bearing, and through drilled channels and lubricate the connecting rod bearings. For piston cooling oil is sprayed through the nozzles to the lower part of the piston.
The second oil flow through the channels is supplied to the cylinder head for the lubrication of bearings of camshafts and hydraulic tappets.
After passing through the head and the cylinder block oil flows into the oil pan.
