preparation example Construction

[0028] Based on the above embodiment, the present invention further presents the preparation method of the engine lubrication system cleaning agent. The method of preparing the engine lubrication system cleaning agent includes the step of forming the oil-soluble polyalkylene glycol and the synthetic hydrocarbon base oil to form a base oil, add an additive to the base oil to make the mixed uniformly form an engine lubrication system cleaning agent .

[0029]Further, the present invention proposes the use of the engine lubrication system cleaning agent. The method of use of the engine lubrication system cleaner includes the following steps: After discharging the old oil oil in some engines, add an engine lubricating system with an old oil volume equal to an engine lubrication system; start the engine idle operation 15 to 60 min; discharge the mix in the engine liquid.

Embodiment 1

[0033] The components of the engine lubrication system cleaning agent include: 85% base oil and 15 wt% additive.

[0034] Among them, the base oil is composed of an oil-soluble polyalkylene glycol and synthetic hydrocarbon base oil from a weight ratio of 4: 1;

[0035] The additive is composed of a dispersant (polyisobutyl butarin), a surfactant (nonylphenol polyoxyethylene ether, and polyethylene glycol, HLB is 12) (weight ratio of 7: 4).

Embodiment 2

[0037] The components of the engine lubrication system cleaning agent include: 85% base oil and 15 wt% additive.

[0038] Among them, the base oil is composed of an oil-soluble polyalkylene glycol and synthetic hydrocarbon base oil having a weight ratio of 3: 1;

[0039] The additive is composed of a dispersant (polyisobutyl butarin), a surfactant (nonylphenol polyoxyethylene ether, and polyethylene glycol, HLB is 12) (weight ratio of 7: 4).

Abstract

The invention discloses a cleaning agent for an engine lubricating system. The cleaning agent for the engine lubricating system comprises the following components in percentage by weight: 80-90% of base oil and 10-20% of an additive, wherein the base oil comprises oil-soluble polyalkylene glycol and synthetic hydrocarbon base oil in a weight ratio of (3-5): 1; and the additive comprises a dispersant and a surfactant in a weight ratio of (5-9): (2-5). The invention aims to provide the cleaning agent for the engine lubricating system, which is high in cleaning capacity and can further decompose stripped large oil sludge.

Description

Technical field [0001] The present invention relates to the field of vehicle maintenance techniques, and more particularly to an engine lubricating system cleaning agent. Background technique [0002] After long-term operation, the engine has gradually oxidized, polymerized, forming a shelter, causing engine operation within the engine, causing engine operation. The engine cleaning method includes: removing the engine cleaning, time consuming long and the engine reassembly is prone to engine performance; after discharging partial oil, the cleaner is filled into the engine, and the engine is operated, and the engine interior is cleaned by the cleaning agent. Shelter. The latter cleaning method is simple, and does not need to be disassembled, and it is widely used. [0003] However, the current engine lubrication system cleaning agent generally has the following defects: (1) The cleaning ability is slightly weak, or it is difficult to decompose larger clay, and after cleaning, the ...
