Octane rating is a measure of a fuel's ability to resist ‘knock.’ The octane requirement of an engine varies with compression ratio, geometrical and mechanical considerations, and operating conditions. The higher the octane number, the greater the fuel’s resistance to knocking or pinging during...
The quick answer is that all fuels and additives are not the same. We typically buy petrol by its octane rating. The octane rating or RON is solely an indicator of how resistant the fuel is to knock. (Knock is premature ignition caused by pressure within the engine) In general most Japan...
A system (10) and method for optimizing the octane rating of fuel supplied to a vehicle (12). The system (10) utilizes information resulting from the occurrence of detonation to make recommendations regarding the fuel octane requirements of the vehicle (12) to the operator of the vehicle (12...
This work presents a systematic investigation of the impact of NO on fuel autoignition in a standard, octane rating engine. Knock onset timing is investigated over a wide range of equivalence ratios, intake temperatures, and fuel compositions with increasing levels of NO added via the engine ...
The efficiency of modern spark-ignition engines is constrained by knock-limited combustion and hence the fuel’s octane rating. This paper investigated the impact of the Research Octane Number (RON) and Motor Octane Number (MON) on the anti-knock performance in a 2.3-L gasoline turbocharged dire...
SINPAR FTC Octane engine provides a complete solution for determining accurate octane number of blended fuels as gasoline of different octane numbers is the main product of fuel blending plant.
Combination Octane Rating Unit FTC-M2 Combination (Research and Motor Method) Octane Rating Unit FTC-M2 is used as a complete system for determining octane number of motor fuels, conforming to ASTM D2699 (ISO 5164) and ASTM D2700 (ISO 5163) Standards.Detail > ...

Methanol has higher octane rating and greater heat of vaporization values as compared to gasoline, making it a suitable candidate for high compression ratio engines with larger power outputs. This is because higher octane rating allows a significant increase in the compression ratio and a higher ...
It has also been observed that by effectively increasing the octane rating of fuel delivered to the combustion chamber, consumers may be able to purchase lower octane rated fuels at the pump. The higher octane rating eliminates the “pinging” that generally occurs when users provide non-...
