Internal combustion engine functional cooling liquid

Abstract

The invention discloses an internal combustion engine functional cooling liquid, which comprises, by mass, 60-80 parts of composite alcohol, 70-90 parts of propylene glycol, 30-50 parts of ethylene glycol, 0.02-0.1 part of a corrosion inhibitor, 0.01-0.05 part of a scale inhibitor, 0.05-0.15 part of denatonium benzoate, 0.02-0.05 part of an anti-foaming agent, 0.1-0.5 part of lactic acid, 8-12 parts of sodium silicate, 5-8 parts of starch, 0.1-1 part of a pour point depressant, 0.5-2 parts of a viscosity reducing agent, 1-3 parts of a metal deactivator, 0.1-0.5 part of a rust inhibitor, 0.1-0.5 part of an antioxidant, and the balance of other substances. The internal combustion engine functional cooling liquid of the present invention has the long service life, does not easily produce scale accumulation, does not corrode copper members, aluminum members and other mechanical parts, has the synchronous service life as the service life of the engine, and further has characteristics of no requirement of replacement maintenance and environment protection.

Description

technical field [0001] The invention relates to the technical field of cooling fluids, in particular to a functional cooling fluid for internal combustion engines. Background technique [0002] At present, the common similar products in the market are generally characterized by short service life, easy oxidation and corrosion, low boiling point and high pressure, easy to accelerate the aging of cooling system pipelines, and easy to produce effervescence inside the cooling system, which will cause internal heat conduction obstacles in the engine and increase engine fuel consumption. Power drops, exhaust emissions increase, and additional air pollutants are likely to be added. For this reason, we propose a functional coolant for internal combustion engines. Contents of the invention [0003] The invention proposes a functional coolant for internal combustion engines, which improves the service life of the product, is more friendly to the environment, increases the boiling po...

[0002] At present, the common similar products in the market are generally characterized by short service life, easy oxidation and corrosion, low boiling point and high pressure, easy to accelerate the aging of cooling system pipelines, and easy to produce effervescence inside the cooling system, which will cause internal heat conduction obstacles in the engine and increase engine fuel consumption. Decreased power, increased exhaust emissions, easy to increase additional air pollutants, so we propose a functional coolant for internal combustion engines
