An octane rating, or octane number, is a standard measure of a fuel's ability to withstand compression in an internal combustion engine without causing...

4-trimethylpentane (commonly called iso-octane), is used as one of the standard values in the octane rating scale. Octane is a component of gasoline and petroleum...

igniting too early are measured as the octane rating of the fuel blend. Gasoline blends with stable octane ratings are produced in several fuel-grades for...

containing additive used to aid in lubrication of the engine, increase octane rating, and prevent engine knocking (premature detonation). There are ongoing...

octane rating became a major focus of aero engine development for the remainder of the war, with later fuels having up to a nominal 150-octane rating...

cooling properties of ethanol. E85 has an octane rating higher than that of regular gasoline's typical rating of 87, or premium gasoline's 91-93. This...

100% heptane fuel is the zero point of the octane rating scale (the 100 point is 100% iso-octane). Octane number equates to the anti-knock qualities of...

octane (C8H18). This particular isomer is the standard 100 point on the octane rating scale (the zero point is n-heptane). It is an important component of...

rating) (CN) is an indicator of the combustion speed of diesel fuel and compression needed for ignition. It plays a similar role for diesel as octane...

gasoline additive used to reduce engine knocking and increase the fuel's octane rating by raising the temperature and pressure at which auto-ignition occurs...

defined. For example, gasoline may have an octane rating between 88 and 102. Because TVO has a lower octane rating than petrol, the engine needs a lower compression...

used as a fuel additive, MTBE is blended into gasoline to increase its octane rating and knock resistance, and reduce unwanted emissions. MTBE is manufactured...
