Description

Technical Field

[0001] The present invention relates to the technical field of liquid fuels, and in particular to a diesel engine power fluid and a preparation method thereof. Background Art

[0002] Diesel is a liquid fuel extracted from petroleum, which can provide energy for engines or other machinery. As a non-renewable fossil energy resource, petroleum reserves are decreasing. With the development of the global economy, especially the rapid rise of emerging economies, the demand for oil continues to increase, which makes diesel engines face the problem of resource shortage on the one hand, and on the other hand, the insufficient combustion of diesel will produce a large amount of harmful substances, which has become the main source of air pollution, and these harmful substances also pose a threat to people's health.

[0003] Although modern diesel engines have adopted many advanced technologies to reduce emissions, diesel combustion still produces relatively more pollutants such as carbon monoxide, particulate matter and nitrogen oxides. These pollutants are not only harmful to the environment, but also increasingly concerned about their emission as environmental protection requirements continue to increase. In addition, the combustion performance of diesel also needs to be further improved.

[0004] Therefore, in order to alleviate the pressure brought by the shortage of oil resources and improve the atmospheric environment, people are committed to studying diesel engine power fluid to solve the above problems. At present, although diesel engine power fluid has certain combustion performance, it still has the defect of insufficient combustion performance. Therefore, developing a diesel engine power fluid with excellent combustion performance can provide more energy and power, which is important for reducing dependence on oil resources and ensuring the sustainability of energy supply. Summary of the invention

[0005] The present invention provides a diesel engine power fluid and a preparation method thereof, which solves the problem of insufficient combustion performance of the diesel engine power fluid in the related art.

[0006] The technical solution of the present invention is as follows: A diesel engine power fluid, comprising the following components in percentage by mass: Fuel 50%~60%, surfactant 4%~8%, additive 6%~12%, the balance is water; The additive comprises the following components in parts by weight: 30-50 parts of alkyl nitrate, 1-11 parts of ferrocenecarboxylic acid, 9-18 parts of dicumyl peroxide, and 2-10 parts of diethyl phosphite.

[0007] As a further technical solution, the weight ratio of dicumyl peroxide to diethyl phosphite is 2-4:1.

[0008] When the weight ratio of dicumyl peroxide to diethyl phosphite is 2-4:1, the combustion performance of the diesel engine power fluid can be further improved.

[0009] As a further technical solution, the additive also includes 2 to 7 parts of o-methylhydroquinone.

[0010] When the additive also includes o-methylhydroquinone, the introduction of o-methylhydroquinone can interact with the other components in the additive, so that the additive can better act on the diesel engine power fluid. Furthermore, the use of o-methylhydroquinone and ferrocenecarboxylic acid can further provide an acidic environment for the power fluid, thereby making the power fluid easier to oxidize during combustion, thereby further improving the combustion performance of the diesel engine power fluid.

[0011] As a further technical solution, the weight ratio of the o-methylhydroquinone to the ferrocenecarboxylic acid is 1:1 to 1.5.

[0012] When the weight ratio of o-methylhydroquinone to ferrocenecarboxylic acid is 1:1-1.5, the combustion performance of the diesel engine can be further improved.

[0013] As a further technical solution, the fuel is diesel.

[0014] As a further technical solution, the surfactant includes two or three of sorbitan monooleate, fatty alcohol polyoxyethylene ether, and ethoxylated fatty alcohol.

[0015] As a further technical solution, when the surfactant includes sorbitan monooleate and fatty alcohol polyoxyethylene ether, the weight ratio of sorbitan monooleate to fatty alcohol polyoxyethylene ether is 3:2.

[0016] As a further technical solution, the alkyl nitrate includes one or both of isooctyl nitrate and isoamyl nitrate.

[0017] The present invention also proposes a method for preparing a diesel engine power fluid, comprising the following steps: S1, mixing and stirring the components in the additive to obtain the additive; S2, mixing the additive, the fuel and the surfactant, and stirring to obtain the mixture; S3, adding water to the mixture, mixing, and stirring to obtain the diesel engine power fluid.

[0018] As a further technical solution, in step S1, during the stirring, the stirring speed is 100~120r / min, the temperature is 40~48°C, and the stirring time is 0.5~1.5h; in steps S2 and S3, during the stirring, the stirring speed is independently 160~180r / min, the temperature is independently 55~65°C, and the stirring time is independently 1.5~2.5h.

[0019] The present invention also proposes the diesel engine power fluid and the application of the diesel engine power fluid prepared by the preparation method in a diesel engine.

[0020] The working principle and beneficial effects of the present invention are: In the present invention, the additive of the diesel engine power fluid contains dicumyl peroxide and diethyl phosphite. The combined use of dicumyl peroxide and diethyl phosphite can improve the combustion process of the power fluid in the diesel engine, promote its rapid and stable combustion, thereby improving the combustion performance of the power fluid, thereby maintaining the normal working performance of the diesel engine. In addition, the addition of ferrocenecarboxylic acid in the additive can improve the combustion performance of the diesel engine power fluid. DETAILED DESCRIPTION
