Abstract

PURPOSE:To obtain an engine oil which has an excellent bearing effect to reduce the friction between a piston and a cylinder by adding to an engine oil spherical or nearly spherical particles which have a specific particle diameter and are insoluble and heat-resistant. CONSTITUTION:Spherical or nearly spherical particles which have a particle diameter of 0.1-30mum, are insoluble in the oil, and have heat resistance are added to an engine oil. Thus, an engine oil is obtained which has an excellent bearing effect to reduce the friction between a piston and a cylinder. When this engine oil is used in, e.g. an automotive gasoline or diesel engine, spherical particles 3 come into the space between a piston ring 2 and a cylinder 1 to reduce the coefficient of friction. As a result, reductions in noise and in fuel consumption are attained. The particles are also effective in inhibiting the engine oil from becoming black. Other effects include the prevention of overheat and a reduction in the content of harmful substances in the exhaust gas.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a method for producing an engine oil additive in an engine using a piston and a cylinder.

[0002]

2. Description of the Related Art Fuel additives and engine oil durability have been improved by adding liquid additives to engine oil.

[0003]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention Reduction of frictional resistance in an engine, improvement of durability of a power system such as an engine, reduction of mechanical noise and vibration, improvement of fuel efficiency, improvement of engine response (responsiveness) such as racing , Improvement of acceleration response, improvement of durability of oil itself, torque up of low rotation, oil up, oil down, seizure prevention effect,
Protection of high temperature turbines, cooling effect, reduction of nitrogen oxides, soot, etc. emitted from the engine.

[0004]

In order to achieve the above-mentioned object, in the present invention, the engine oil contains 0.1 to 30 μm.
Spherical shape that does not dissolve up to micron, and has the heat of shochu,
Alternatively, a relatively ball-like substance was added to the engine oil to give the piston and cylinder of the engine the effect of bearings.

Addition of the above substances will bring about the effect,
The effect diminishes when used in large quantities. However, better results have been confirmed than when nothing is added. In addition, the effect can be expected even with an extremely small amount.

[0006] Additives include liquids dissolved in oil and powders, both of which are injected through the engine oil inlet.

The above additives are more effective when the engine oil is added to a new state.

[0008]

[Operation] When engine oil containing the above substances is used, particles will enter between the piston ring and cylinder.

Then, for the above reason, the bearing effect occurs.

[0010]

[Example] Explaining an example in Table 1, it shows the fuel consumption improvement rate before and after addition of a substance by a gasoline vehicle after oil change.

The examples shown in Table 2 show the fuel consumption improvement rate before and after addition of the substance by the diesel vehicle after the oil change.

The examples shown in Table 3 are based on
The noise after addition and the frequency of the noise were examined with a Diesel car.

The examples shown in Table 4 are before the addition of the substance
The noise after addition and the frequency of the noise were investigated in a gasoline car.

[0014]

Since the present invention is constructed as described above, it has the following effects.

Addition to engine oil improves fuel efficiency, engine noise is quieter, oil is not black and dirty, overheat is less likely, exhaust gas is reduced, water leakage from muffler is reduced, maintenance cost is reduced. .

[0016] And, the introduction cost is low and the cost can be recovered immediately.
