Description

(54) FORCEED MOTOR OIL The invention relates to lubricants and can be used for high (zforforsirovanny engines. A masse for mineral oil-based forced engines with the addition of magnesium iron and high gallium alkylphenolate f is known. The closest to the proposed oil is oil for forcing engines based on mineral oil, containing magnesium alkylsaline, high alkaline alkyl phenol t barium, succinimide additive and additive based on shielded phenols and Resolutes f2. However, the operation of the engines on these oils is hindered due to soot formation on the pistons and due to poor detergency properties and due to low anticorrosive properties. During testing, considerable wear of the piston rings is observed. DI1GATELY Chain is achieved by the fact that the oil containing magnesium apkylsapicilate and antifoam additive, additionally contains high-grade calcium sulphonate and 4-neopentyl-5-re-butyl-1,2-dithiacyclopente n-4 thion-3 in the following ratio of components,%: Magnesium alkyl salicylate.

From tab. 1 that the introduction of L -TIB-6A additives into the proposed reperture results in a slightly unexpected effect. So, the named additive is known as anti-wear, in combination with other ingredients dramatically increases not only anti-wear, but also anti-corrosion and detergent properties of the proposed oil (examples 3 and 4).

It should be emphasized that replacing the LZ-TIE-6A additive with the anti-wear additive Tritiolan (4,7-di-chlorobenzo-1,2,3-tritia-hydrinden) in this formulation does not lead to a positive effect, but on the contrary, dramatically increases the wear of parts and impairs the corrosion properties

va oils (example 5). And this in particular, it follows that the use of anti-wear additives without taking into account the influence of other components of the oil does not always lead to a decrease in wear.

In tab. 2 shows the operational properties of the oil.

From tab. 2 it follows that the absence of anti-wear additives LZ-TIB-BA while maintaining the remaining ingredients also dramatically increases wear and, quite unexpectedly, affects the corrosive and detergent properties of the oil.

Invention Formula Engine oil for forced engines based on mineral oil, containing alkyl salicylate and antifoam additive, is often due to the fact that, in order to increase the anti-wear, anti-corrosive and detergent properties of the oil, it additionally contains calcium alkali sulfonate and 4-neopentyl-5 tert- butyl-1,2-dithiacyclopentene 4thion-3 in the following ratio of components,%: Uptake of magnesium 3, O-5, O High chain sulfo, Calcium Nat 0.5-2.0 32.1 2O, 2 14.3 16.8 16.8 4-Neopentyl-5-tert-butyl-1, 2-dithiacyclopenten-4-thion-C 0.5-2.0 Anti-foaming additive O, O01 -.- 0, O05 Mineral maspo up to 100 Sources of information taken into account in the examination 1, USSR author's certificate NO 263797, cf.
