Description

Fuel additive composition for internal combustion engine

The present invention relates to a fuel additive composition for an internal combustion engine, and more particularly, to a fuel additive composition for a gasoline or diesel internal combustion engine.

Fuel additives clean the residues in the engine due to incomplete combustion of fuel or reduce carbon deposits (CCD) to keep the combustion chamber at a low temperature during the combustion process, and to reduce the recombustion process of residues or carbon deposits. It is used to disappear through Specifically, when residues or carbon deposits in the engine disappear, the volume of the combustion chamber increases, allowing more oxygen to flow in, and the combustion propagation speed (flame propagation speed) can be accelerated. Accordingly, it is possible to maintain the combustion chamber temperature at a low temperature, and an increase in output and improvement in fuel efficiency can be expected.

Commonly used fuel additives focus on cleaning, and these include cleaning components for cleaning and removing residues from the combustion chamber in the engine, and surfactant-based cleaning components such as polyetheramine (PEA) The explosion temperature (flash point) is higher than that of fuel, so it is difficult to combust with the fuel. As a result, if the components that have not been completely combusted pass through the piston ring and seep into the engine oil, the viscosity of the engine oil is diluted, which leads to engine oil lubrication. The performance will be reduced, which can cause serious problems with the engine.

On the other hand, as a prior patent document related to fuel additives, Korean Patent Registration No. 10-0544568 discloses a fuel additive comprising an amine-based stabilizer, hydrogen peroxide, sodium hydroxide, and borax in a specific weight ratio. 10-0584224 discloses a fuel additive for an internal combustion engine containing a hydrocarbon-based solvent and an additive, but in these prior patent documents, the fundamental problem of incomplete combustion of fuel in the engine combustion chamber is not solved, but due to incomplete combustion of fuel It is only focused on the late removal of carbon deposits that have already occurred, and in this case, it is difficult to expect additional effects such as improvement of fuel efficiency, improvement of output and torque, prevention of DPF clogging, and reduction of urea water consumption.

On the other hand, the term "hydrotreated heavy paraffinic refined oil (Hydraulic Fluid)" used throughout the specification and drawings of the present invention is a complex combination of hydrocarbons obtained by treating petroleum fractions with hydrogen in the presence of a catalyst, mainly C ₂₀ to C ₅₀ It is composed of hydrocarbons having a range of carbon atoms, and may mean to include a relatively large proportion of saturated hydrocarbons.

Conventionally widely used fuel additives include cleaning components for cleaning and removing residues from the combustion chamber in the engine. It is difficult to be combusted with fuel because of this, and if the components that have not been completely burned pass through the piston ring and seep into the engine oil, the viscosity of the engine oil is diluted, which leads to a decrease in engine oil lubrication performance, which in turn affects the engine. It can cause serious problems. In addition, these fuel additives do not solve the fundamental problem of incomplete combustion of fuel in the engine combustion chamber, but only focus on the subsequent removal of carbon deposits that have already occurred due to incomplete combustion of fuel. There was a problem that it was difficult to expect additional effects such as over-torque improvement, DPF clogging prevention, and reduction of urea water consumption.

In the case of hydrotreated heavy paraffinic refined oil, as described above, it is a complex combination of hydrocarbons obtained by treating petroleum fractions with hydrogen in the presence of a catalyst, mainly composed of hydrocarbons having a carbon number in the range of C ₂₀ to C ₅₀ , and relatively many It may include saturated hydrocarbons in a ratio, and specifically, hydrotreated heavy paraffinic refined oil (Hydraulic Fluid) may be included in 95 to 99.5 wt% based on the total weight of the composition.
