octane number evolution for enabling alternative low RON refinery streams and octane boosters as transportation fuels", Fuel, vol.
Today, the properties of petrol are generally enhanced through improving the chemical structure of petrol, upgrading production technologies and adding the required amount of oxygenates (MTBE, ETBE, etc.), the
octane number whereof, as determined by the method of testing, makes up 118.
Traditionally, refineries have had to take gasoline samples back to the lab for analysis to determine the in-process
octane number. That creates an extended time lapse between analyzing and making adjustments to the product, LeFebre said, and the sampling process does not always offer a true representation of what's happening in the pipe.
This study investigated gasoline HCCI, low
octane number gasoline (G80, 80% gasoline+20% diesel by volume) HCCI, and gasoline Direct Injection Compression Ignition (DICI) to explore the highest achievable thermal efficiency for passenger cars application.
LPG 1, with a purity grade of 99 % propane, shows the highest knock characteristic numbers (methane number and motor
octane number).
The Gulf country for the first time exported gasoline with low 75 research
octane number (RON) in August, Reuters reported, after government officials told domestic news services that it had become self sufficient and started to export.
For petrol the main parameters of concern were research
octane number, summer vapour pressure and distillation-evaporation at 100[degrees]C.

Gasolines with knock tendencies between those two primary reference fuels are generally characterized by a Research
Octane Number (RON) and/or a Motor
Octane Number (MON).
In August last year, Honda Atlas Cars Pakistan in a complaint to Ogra reported high manganese content in recently upgraded 92RON (Research
Octane Number), causing three major issues: catalyst blocking or choking of the catalytic converter, engine knock due to low octane quality fuels and adverse human health effects of manganese.
