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 mor

Abstract

The invention provides environment-friendly engine trying liquid. One liter of the environment-friendly engine trying liquid comprises 120 to 200g of ethylene glycol, 6 to 15g of polycarboxylate (TH-361), 0 to 2.5g of sodium cinnamate, 10 to 20g of p-hydroxybenzoic acid monosodium salt, 3 to 6g of sebacic acid, 0.5 to 1.5g of sodium phytate, 3.5 to 8.5g of sodium gluconate, 0.5 to 2g of H-benzotriazole, 0.2 to 1g of 2-mercaptobenzothiazole, 2 to 6g of sodium metasilicate, 0.5 to 1g of water soluble pigment, and the balance of deionized water. The environment-friendly engine trying liquid is used for trying an automobile engine before the automobile engine leaves a factory, testing the factory performance, and early-stage preliminary grinding-in; various metals of an automobile engine system have heat and cold alternating gas-liquid phase rust prevention capacity, and are high in recycling stability; and a product does not have nitrite, amine salt, phosphate and other substances, is non-toxic and innocent, does not pollute environment and can be used safely and is environment-friendly.

Description

technical field [0001] The invention relates to an automobile engine test fluid, in particular to an environment-friendly engine test fluid with alternating cold and heat gas-liquid phase antirust capabilities, which is applied to various automobile engine industries. Background technique [0002] Before the engine is fully assembled and leaves the factory, it is necessary to conduct a test run for each engine. This is the so-called test run, that is, to simulate the normal operation of the engine under a certain load, operation, power and temperature to investigate the quality of the engine assembly and adjustment. Whether there is no error or missing installation, whether it can run normally; check whether the factory performance of the engine meets the technical requirements, and carry out early preliminary running-in. [0003] During the test run, the cooling system of the engine should be filled with test machine fluid. At present, there are few domestic manufacturers ...
