Fig. 2.186. Components of system of greasing

Greasing system the combined: a razbryzgivaniye and under pressure. Under pressure radical and shatunny bearings and support of camshafts are greased. The system consists of an oil case, the shesterenchaty oil pump with a maslopriyemnik, the polnopotochny oil filter, the sensor of pressure of oil and oil valves.

The oil pump takes away oil from the pallet of a case of the engine and submits it to the oil filter. From forcing of the oil pump there is perepuskny a valve. At too high pressure of oil the valve opens, and the part of oil flows down back in the engine pallet.

Through the middle of a filtering element of the oil filter pure oil arrives to the trunk oil main. At a contamination of the filter bypass the valve located in the case of the oil filter, submits not filtered oil directly to the trunk oil main. In a branch pipe of the oil filter there is a return valve which interferes with a devastation of oil channels and hydraulic pushers of valves of the engine. Channels depart from the trunk oil main for greasing of bearings of the crankshaft. Through inclined openings in the crankshaft oil moves to shatunny bearings, and from there is sprayed on piston fingers and cylinders. At the same time on ascending channels oil moves in a head of the block of cylinders and ensures functioning greasing of bearings of a camshaft and hydraulic pushers.

Speaking about a consumption of oil in an internal combustion engine, that amount of oil which is spent owing to combustion process (an expense on waste) means only. At all it is not necessary to confuse a consumption of oil to the loss of oil occurring because of a leakage of the pallet of a case, a cover of a head of cylinders etc. The normal consumption of oil arises owing to combustion of a small amount in cylinders, and also because of branch of the remains of combustion and particles of products of wear. Oil wears out under the influence of high temperatures and the high pressure arising in cylinders of the engine. External factors also make on a consumption of oil a great impact, such as a driving manner, and also accuracy of manufacturing of details of the engine.

The most admissible in operation the consumption of oil can make 1,0 l on 1000 km of run.

On reaching a minimum mark oil should be added surely (the amount of added oil should not exceed 1 l).

ATTENTION On the cars equipped with engines with catalytic converter, it is necessary to watch that oil level on masloizmeritelny щупу was not higher than a maximum mark. If in the car with catalytic converter too much oil was filled in, its superfluous part should be removed from a case with means plum or a suction (the special vacuum pump), otherwise not burned down oil will get into system of production of the fulfilled gases and can destroy catalytic converter.

All-weather oil is applied to greasing of engines of cars of Hyundai. All-weather oils have that advantage that they can be used both in winter, and in summertime. All-weather oils are based on liquid seasonal oils (for example, a viscosity class 15W). At the expense of so-called thickeners oil is stabilized in a hot condition so for each condition necessary lubricant properties are provided. «W» on classification of SAE specifies that this oil can be used in the winter.

Legkokhodnye oils represent all-weather oils with antifrictional additives, at their application the economy of fuel to 2 % is possible. Legkokhodnye oils have low viscosity (for example, 10W-30). They demand a special basis (synthetic oils).

Recommended class of quality of oil on API: HE BELOW SG or SH.

Recommended class of viscosity of oil on SAE: depending on the expected temperature of air before the following replacement of oil.
