Predicting octane number from microscale flame dynamics

The standard method for measuring the octane number of fuels requires large sample volumes ( ∼ 1L) and access to a Cooperative Fuel Research (CFR) engine. This method reliably quantifies the knock resistance of fuels in spark ignition engines, however the large sample volume requirement prevents testing of new experimental fuels (often produced in quantities of just ∼ 1 mL), and the large equipment size impedes mobile, decentralized testing of...
