Problems solved by technology

[0003] Domestically, the anti-rust oil used in the engine fuel system for storage is now used. After the storage is completed, the anti-rust oil needs to be removed from the system and the fuel system can be cleaned before the fuel system can work normally. It does not have the function of gas-phase anti-rust , and cannot directly start combustion; the U.S. military standard also has gas-phase anti-rust oil for rust prevention in confined spaces, but it cannot be used for rust prevention of magnesium parts, cadmium-plated parts, and rubber parts. In addition, there are combustion and other anti-rust oils. Problems such as gelling when rust oil is mixed, the requirements cannot meet the requirements that the product can burn without affecting the starting performance

preparation example Construction

[0022] The concrete steps of the method for the preparation of antirust oil of the present invention are as follows:

[0023] (1) Add liquid-phase antirust agent A and liquid-phase antirust agent B to gas-phase antirust agent A in proportion to pre-dissolve into a solution.

[0024] (2) Add diesel oil to the blending kettle, stir and add liquid phase antirust agent A, liquid phase antirust agent B and gaseous phase antirust agent A pre-solution,

[0025] (3) Finally, add gas-phase antirust agent B in proportion, and after stirring, filter and store in sealed tanks.

[0026] When using the product of the present invention, clean up the remaining diesel oil in the fuel tank before sealing, add the sealed anti-rust oil to the fuel tank, start the engine to make the fuel system full of sealed anti-rust oil, and play the role of anti-rust sealing after shutting down. The stored oil can directly participate in combustion when starting.

Embodiment 7

[0030] First carry out test on common engine, add the antirust oil of embodiment 1 into the fuel tank of small-sized tractor, carry out startability test, start and run continuously for 2 hours, engine works normally, then carry out the low-temperature cold start and operation of this oil Test, cold start and engine running data are shown in Table 3

Abstract

The invention relates to antirust oil for a diesel engine fuel system and a preparation method thereof. The antirust oil comprises the following components in percentage by mass: 75 to 82 percent of diesel, 5 to 10 percent of liquid-phase antirust agent A, 0.1 to 0.5 percent of liquid-phase antirust agent B, 8 to 12 percent of gas-phase antirust agent A and 3 to 5 percent of gas-phase antirust agent B. The invention provides the antirust oil which can not only satisfy the storage requirements of an engine, but also satisfy the direct starting requirements of the engine. The antirust oil not only has the liquid-phase antirust function, but also has the gas-phase antirust function in the antirust respect. Residual diesel in an oil tank is cleared up before the antirust oil is stored, the stored antirust oil is added into the oil tank, the engine is started so that the stored antirust oil is fully filled in the fuel system so as to play an antirust storage function after the engine is stopped, and the stored oil can be directly engaged with combustion during the next starting without influencing the starting performance of the engine.

Description

technical field [0001] The invention belongs to the technical field of antirust products, and in particular relates to a formula and a preparation method of an antirust oil for a diesel engine fuel system. Background technique [0002] The engine is the heart of the car, and the fuel system of the engine is the aorta of the engine. Some vehicles often have to be placed for a period of time from the factory to the actual use, especially military combat vehicles, which need to be sealed and parked for a long time. Water will inevitably enter during storage, transportation and use. The water will be adsorbed on the inner surface of the fuel system metal in a static state, which is extremely harmful to the fuel system. It can corrode various parts of the fuel system and be corroded. Spots often appear on the metal surface, and the corrosion products will block the filter, and sometimes even jam the valve, sleeve, piston and other precision parts, thereby destroying the normal op...
