Problems solved by technology

In the usual sense, the strong anti-corrosion ability of the coolant means that when the cooling system is filled with coolant and the relevant components are in full contact with the coolant, the cooling system can be guaranteed not to be corroded. When a small amount of coolant keeps the system in the state of cold gas phase-cold liquid phase coexistence for a long time, since the coolant does not contain gas phase anti-rust components, its main component is ethylene glycol, which is easy to hydrolyze and becomes acidic, which actually makes the cooling system rust more easily, thus Affect the normal quality and service life of the engine

Abstract

The invention discloses environment-friendly multi-effect type cooling liquid for testing an engine. The environment-friendly multi-effect type cooling liquid comprises the following components in percentage by mass: 8-10% of a ferrous metal antirusting agent, 2-3% of a non-ferrous metal antirusting agent, 15-20% of organic amine, 3-5% of a vapor-phased corrosion inhibitor, 5-8% of all-purpose cellosolve, 0.1-0.2% of a defoaming agent and the balance of deionized water, wherein the total percentage is 100%. The environment-friendly multi-effect type cooling liquid disclosed by the invention has the beneficial effects that the anti-rusting property and the vapor-phased anti-rusting property are excellent, no corrosion to metals under high temperature is achieved, the anti-rusting property is stable, the cleaning property is excellent, oil-stain impurities in a water jacket of the engine can be effectively cleaned, condensation of steam is prevented from rusting an inner cavity, the engine can be protected from being corroded, the anti-rusting period is long (up to more than 90 days), residual liquid and other engine antifreezing liquids have excellent compatibility, and after addition of a proper amount of the antifreezing agent, the cooling liquid can be used as the engine antifreezing liquid and is safe and environment-friendly.

Description

technical field [0001] The invention relates to a cooling liquid, in particular to an environment-friendly and multi-effect engine test machine cooling liquid. Background technique [0002] The test run refers to the assembled engine, which needs to be tested before leaving the factory. Its purpose is to check the quality of engine assembly and adjustment by operating the assembled engine normally under various working conditions, and to check whether the performance of the engine meets the factory index conditions, and to carry out preliminary running-in. Before the test run, the engine cooling system should be filled with test machine fluid to ensure the normal operation of the system. After the engine test run, drain the liquid in the cooling system and store it or send it to the OEM for loading. The main function of the test machine fluid is to ensure the normal cooling of the engine and the cooling system will not rust during storage and transportation after the liqui...
