Basics
- A Measure of how much compression a fuel can handle before ignition
- Higher Octane Rating means a higher Compression Ratio can be used in a Spark Ignition Engine
- Important to control Engine Knocking
- Largely Irrelevant to Diesel Engines as Cetane Value tends to be used
- Should OSE use RON as the measurement of choice?
Quick Reference Table of Various Fuels
- Carbon Monoxide ? (Useful for Calculating Charcoal Gasifier Engine Parameters, as well as engines using waste gas from Refineries)
- Diesel Fuel 15-25
- Dimethyl Ether 105-123
- Ethanol 108.6
- Hydrogen More than 130?
- Methane 120
