Autoignition Behavior of an Ethanol-Methylcellulose Gel Droplet in a Hot Environment

Energies, 2018
Autoignition of an ethanol-based gel droplet was experimentally investigated by adding 10 wt % of methylcellulose as gellant to liquid ethanol. Experimental studies of the ignition behavior of the gel droplet were found to be quite rare.

Autoignition characteristics of oxygenated gasolines [PDF]

Combustion and Flame, 2017
Gasoline anti-knock quality, defined by the research and motor octane numbers (RON and MON), is important for increasing spark ignition (SI) engine efficiency. Gasoline knock resistance can be increased using a number of blending components. For over two decades, ethanol has become a popular anti-knock blending agent with gasoline fuels due to its ...
