Additives for automobile petrol
Octane-boosting additives
Active base: aromatic amines
Application
The use of octane-boosting additives makes it possible to significantly increase the octane number without increasing the content of oxygen-containing compounds, which is especially important in the production of high-octane petrol.
An example of the results of testing an additive on low-octane petrol involving 1.5 and 2% by weight.
| Component composition of the mixture | Octane number by the research method | Octane number by the motor method | Octane number increase: RM, units/MM, units |
|---|---|---|---|
| Basic mixture | 93,2 | 86,4 | – |
| A mixture with the addition of 1.5% by weight. additives | 96,0 | 87,9 | 2,8/1,5 |
| A mixture with the addition of 2% by weight additives | 96,8 | 88,9 | 3,6/2,5 |
The use of an octane-boosting additive increases the detonation resistance of petrol, thereby ensuring the stability of the fuel combustion process.
