Fuel Additives Part 2: Effects of Octane Improver Not Just Octane Number

There are various base materials for fuels with high octane ratings, each with its own specific properties and advantages. In this article, we will focus on some of the most common among them.
Characteristics of Alcohol-Based Fuels

Due to their high latent heat, alcohol-based fuels have the effect of lowering the temperature inside the combustion chamber. This prevents the internal temperature of the engine from rising during the combustion process, resulting in a higher octane rating. This cooling effect also contributes to improved engine performance and combustion efficiency.
Advantages of Aromatic Benzene and Cyclic Structure Fuels

Aromatic benzene-based and cyclic-structured cyclo-fuels are very stable chemically and thermally. These compounds offer high octane ratings due to their stable structure and provide consistent performance during the combustion process in engines.

Role of Organometallic Octane Improvers

Organometallic octane improvers not only improve octane but also function as a combustion catalyst. This improves the combustion state inside the engine and also lubricates the valve train and piston area, resulting in an overall improvement in engine performance.
Actual exhaust gas tester measurements have confirmed that organometallic octane improvers reduce the release of CO (carbon monoxide) and HC (hydrocarbons) as unburned residues.
It also has the effect of quieting engine operation, especially in direct injection engines, significantly reducing injector operation noise. However, the exhaust sound will be louder and the sound quality will change sharper as combustion improves.
If you are using the stock muffler, this is not a concern.

We are on track to produce fuel with an octane rating of 120 or even 140 points, but this alone is not enough to make sense, and we hope to develop a fuel that will provide better combustion conditions in the near future.
