Description

 The invention relates to the field of engine building, and in particular to engine lubrication systems.

 A known lubrication system of an internal combustion engine, including an oil pump, pressure and output lines for oil circulation, filters for oil cleaning (see, for example, A. S. USSR 1686197, F 01 M 11/03, publ. 23.10.91).

 A disadvantage of the known lubrication system of an internal combustion engine is that it does not provide oil purification from sulfur oxide (IV) and water, which are formed during the combustion of fuel containing hydrogen sulfide, in particular associated petroleum gas.

 The basis of the invention is the task of improving the quality of oil purification by extracting sulfur oxide (IV) and water from it.

 The problem is solved in that the lubrication system of the internal combustion engine includes an oil pump, a pressure line and an output line for oil circulation, filters for oil purification, an additional filter with an adsorbent filler for absorbing sulfur oxide (IV) is installed in the pressure line of the oil pump, while the filter is connected to a mechanical oil filter installed in the same pressure line, a second additional filter with an adsorbent floor can be installed in the pressure line carrier for water absorption, and the first and / or second additional filters can be installed after the filter for mechanical cleaning of oil.

 Since the lubrication system of the internal combustion engine in the pressure line of the oil pump has an additional filter with adsorbent filler for absorption of sulfur oxide (IV), the additional filter is connected to a mechanical oil filter installed in the same pressure line, and in the pressure line it can be a second additional filter with adsorbent filler is installed to absorb water, and the first and / or second additional filters can be installed after the mechanical filter oil flow, the oil is purified from sulfur oxide (IV) and water with its purification and from mechanical impurities.

 The drawing shows a lubrication system of an internal combustion engine.

 The lubrication system of an internal combustion engine includes an oil pump 1, a pressure head 2 and an output 3 line for oil circulation, an additional filter 4 with an adsorbent filler for absorbing sulfur oxide (IV), a filter for mechanical oil cleaning 5 installed in the pressure line 2. In the pressure line, it can a second additional filter 6 with an adsorbent filler to absorb water should be installed. The first 4 and / or second 6 additional filters are installed after the filter 5 for mechanical cleaning of oil.

 The lubrication system of an internal combustion engine operates as follows.

During the operation of the engine with associated petroleum gas or other gaseous fuels containing hydrogen sulfide, sulfur (IV) oxide and water are formed during the combustion of methane and hydrogen sulfide. In turn, sulfur oxide (IV) and water, falling into the crankcase 7, condense at a temperature of about 70-80 ^o C and, reacting with each other, form sulfuric acid. The formation of sulfurous acid leads to intensive erosion of engine parts, therefore, after passing the oil through the engine and entering it back into the crankcase 7, the oil first passes through the filter 5 for mechanical cleaning of oil and enters an additional filter 4 with an adsorbent filler to absorb sulfur oxide (IV), wherein it is freed from sulfur oxide (IV) by reaction with an adsorbent. Since the oil is preliminarily purified from mechanical impurities, the additional filter 4 with an adsorbent filler is not contaminated with these impurities and the oil pressure in the lubrication system remains within the required operating limits. To purify oil from water, a second additional filter 6 with adsorbent filler can be installed in the pressure line 2 to absorb water, which further improves the quality of oil purification. As adsorbents, for example, cialite (NaX or CaA) can be used to absorb sulfur (IV) oxide, and finely porous silica gels can be used to absorb water.

 Thus, effective cleaning of oil from undesirable chemical compounds and mechanical impurities is achieved, the time between oil changes is increased, the quality of the lubricant is improved, which increases the life of the engine as a whole, eliminating corrosion of its individual parts.
