SU1209904A1 - Lubricating system of internal combustion engine - Google Patents

Description

The invention relates to mechanical engineering and can be used in lubrication systems for internal combustion engines (ICE) of automobiles with an oil pump located outside on the crankcase of the engine.

The purpose of the invention is to increase the reliability of the iiocTii system by accelerating the delivery of lubricant to the pump, reducing hydroconductivity and eliminating air leaks.

FIG. 1 shows an oil sump, top view from the mating surface; in fig. 2 - section A-A on (fi and r. 1.

The lubrication system of the internal combustion engine contains an oil sump 1 and an oil receiver placed in the crankcase.

The body of the oil receiver is made integral with the crankcase in the form of a cylindrical boss 2 on the bottom 3 of the crankcase with the inflow 4 to its wall and the internal cavity 5. Boss

2 is provided with receiving openings 6 and a lid 7 on the side of the free end, mounted electrically on the boss. The filter mesh 8 of the oil receiver is placed between the lid 7 and the boss 2. In the lid 7

and lug (hole 9.

In addition, the lubrication system is equipped with a pump (not shown) and a receiving tube for supplying lubricant to the pump, the latter being made in the form of a channel 10 i tide 4 and connected to the internal cavity 5 of the bobik 2 through the opening 9 1 of the cover 7 located above the filter screen .

EiepxHOCTb is connected to the attachment plane of the oil pump and the suction port of the pump is connected to channel B of the tide.

The junction of the planes of the oil sump and the pump is sealed with a coy.

When the engine is running, the oil from the crankcase 1 passes through the receiving openings into the internal cavity of the 5 boss. Then, through the filtering mesh 8 and the opening 9 in the lid 7, the oil flows freely through channel 10 at high tide 4 to the mating surface of the oil sump connected to the pump and enters the pump.

The implementation of the oil receiver at the same time as the crankcase, and the receiving tube in the form of a channel in the tide greatly simplifies the design of the oil receiver, eliminates a number of parts. The presence of a lid that seals the end of the oil receiver and has an opening for the passage of oil makes it possible to ensure unimpeded supply of oil from the crankcase to the pump and eliminate 1ODCOS of air into the lubrication system. A direct channel at high tide and the absence of steps and knees in the path of the oil to the pump reduces the loss of hydroresistance and accelerates the flow of oil to the pump. All this taken together increases the reliability of the engine lubrication system.

In addition, the oil receiver has a lower metal consumption than the number of parts compared to the known one. It is in production, which allows to reduce energy and labor costs and, consequently, the cost of production.
