Abstract

A fully formulated coolant for a heavy-duty engine adopts propylene glycol and ethylene glycol as basic liquids and compounds various composite additives including ethanol as an auxiliary, an inhibitor, an inhibition auxiliary, a rust inhibitor, deionized water and an antifoamer. The fully formulated coolant for the heavy-duty engine, disclosed by the invention, adopts an organic acid collaborative protection technique to solve the cavitation corrosion problem of a diesel engine cylinder so as to enhance protection capability, has excellent corrosion and rust resistance, storage stability, hard water resistance, cylinder cavitation corrosion protection and scale prevention, does not require a periodically compensated additive, has good thermostability and anti-foaming performance, is stable in form and outstanding in cooling effect, can prolong the service life, and can meet use requirements of a cooling system for a large-power and heavy-duty engine.

Description

technical field [0001] The invention belongs to the cooling system of a heavy-duty engine, in particular to the field of full formula heavy-duty engine coolant. Background technique [0002] With the advancement of science and technology and the needs of economic development, vehicles are being developed in the direction of large tonnage, high power and heavy load. A heavy-duty engine refers to an engine that operates close to the rated power for a long time. It can be a diesel engine, a gasoline engine or an engine using other fuels. Its load factor is higher than that of a light-load engine and its use frequency is high. The cooling system has strict requirements. Taking the heavy-duty diesel engine as an example, it is characterized by supercharging and strengthening technology, high output power, and large heat generation; poor working conditions, high operating frequency, high reliability and durability requirements; Under long-term operation, the heat dissipation is ...
