Oil pump
At full «gas» 30 liters of oil are pumped through the engine in one minute.
The principle of operation of the pumps of engines 1.6 l and 1.8 p differs from the engine 2.0 l:
- • 1.6L and 1.8L engines are equipped with gear type oil pumps. The two external gears simply push the oil from the suction side to the discharge side.
Installation elements of the oil pump and balancer shafts of engines 1.6 l and 1.8 l since 1993 of release
1 - right balance shaft;
2 - left balancer shaft;
3 - oil pump cover;
4 - oil pump gear;
5 - elements of the pressure reducing valve;
6 - oil filter bracket;
7 - oil filter;
8 - front cover of the engine.
- The 2.0L engine is equipped with a rotary oil pump. It uses a gear with external teeth inside an internal gear (this is the two rotors). Due to the special shape and eccentric arrangement of the inner gear, it is achieved that during the mutual rotation of both gears, vacuum cavities are formed all the time in new places. Thus, engine oil is sucked in. From the rotating gears, the oil is pushed to the outlet of the pump and from there into the lubrication channels. The rotary pump is driven directly by the crankshaft.
Elements of the oil pump of the engine 2.0 l
1 - gasket;
2 - cover;
3 - external gear of the oil pump;
4 - oil filter;
5 - elements of the pressure reducing valve;
6 - stuffing box;
7 - front cover (oil pump housing);
8 - internal gear.
Oil temperature
Oil temperature is essential for proper engine operation.
Too low oil temperature harms the engine. In this case, the oil does not fully show its lubricating properties. Therefore, it is not recommended to accelerate the engine above 3500 rpm until the oil temperature reaches 60°C. For automobiles, it is estimated that oil takes about twice as long to reach operating temperature as coolant.
