Abstract

The invention relates to the field of chemical engineering heat transfer, in particular to a non-aqueous system cooling medium used as internal-combustion engine cooling liquid. The invention particularly discloses non-aqueous system internal-combustion engine cooling liquid. The non-aqueous system internal-combustion engine cooling liquid contains propylene glycol, glycol, sodium benzoate, sodiummolybdate and benzotriazole, and is characterized in that the content of the propylene glycol is less than 40 percent. The freezing point of the non-aqueous system internal-combustion engine coolingliquid is below 49 to 13 DEG C below zero, so that the non-aqueous system internal-combustion engine cooling liquid can be widely used in gasoline engines and diesel engines. For the non-aqueous system internal-combustion engine cooling liquid, the corrosion resistance and the cavitation erosion resistance are far beyond those of the aqueous system cooling liquid, the boiling point is over 180DEGC, the normal-pressure operation is achieved, the combustion efficiency is improved, the oil consumption is lowered, and the emission of waste gas is reduced. The non-aqueous system internal-combustion engine cooling liquid does not contain heavy metals, amines, phosphides and chlorides, and meets the ROHS standard of the EU.

Description

Technical field: [0001] The invention relates to the field of chemical industry, in particular to a non-aqueous chemical product used as an internal combustion engine cooling liquid, in particular to a non-aqueous internal combustion engine cooling liquid. Background technique: [0002] The main body of the traditional internal combustion engine coolant is composed of a mixture of ethylene glycol and water with additives such as anti-corrosion agents. The disadvantage is that the water content is above 40%, so that the boiling point of the mixture is mainly determined by water, and it is easy to vaporize after exceeding 100°C, and it is easy to generate air resistance in high temperature parts of the engine, and easy to generate cavitation in cylinder liners and water pumps. In order to increase the boiling point temperature, the entire cooling system must be closed to make the system work under a certain positive pressure, which undoubtedly increases the pressure rating of ...
