| 1. | RON ( Research Octane Number ) defines the octane level of the fuel.
|
| 2. | One of the best known is the research octane number ( RON ).
|
| 3. | Because benzene has a high octane number, it is an important component of gasoline.
|
| 4. | The engine design of a vehicle is the determining element of the octane number requirement.
|
| 5. | Gasoline is graded by octane number, which rates its resistance to premature ignition, or engine knocking.
|
| 6. | Where the octane number is raised by blending in ethanol, energy content per volume is reduced.
|
| 7. | Isobutane is primarily used by refineries to enhance ( increase ) the octane number of motor gasoline.
|
| 8. | Alkylation processes transform low molecular-weight alkenes and iso-paraffin molecules into larger iso-paraffins with a high octane number.
|
| 9. | The Motor Octane Number, or MON, is assigned to the knock resistance during part-throttle and high-speed applications.
|
| 10. | The octane number is an empirical measure of the resistance of gasoline to combusting prematurely, known as knocking.
