Under vacuum, the oil is sucked in through the sieve of the oil receiver from the oil sump and is pumped by an internal gear oil pump mounted on the toe of the crankshaft into the oil filter. The purified oil is supplied to the main bearings of the crankshaft, to the connecting rod bearings and through the channels in the cylinder head to the camshaft bearings. In engine models «KU» And «NF» oil under pressure enters the hydraulic valve lifters, which automatically compensate for the working clearances of the valves.
Oil pump
The gear type oil pump with internal gears is driven directly by two lugs on the crankshaft. On the right side of the oil pump cover, which is also the holder of the front crankshaft oil seal, a pressure reducing valve is installed.
Oil pressure in the system at an oil temperature of 80°C, kg/cm2:
- at idle: 0.15-0.45;
- at a crankshaft speed of 2000 rpm: 2.0 (at a lower value, the oil pressure warning lamp in the instrument cluster lights up).
Reducing valve actuation pressure, kg/cm2: 5.3-6.3.
Oil filter
An oil filter with a replaceable filter element is connected in series with the main engine oil line.
Brand and type of oil filter element: Mann W 719/5 or Purflux LS 115.
Engine oil
Lubrication system capacity, l: 4.5 (including 0.5 l in oil filter).
Oil used: SAE 5W20, 10W40 or 15W50.
Oil change interval: every 15,000 km.
