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 ...

Controlled autoignition in stratified mixtures
Combustion and Flame, 2021 The shockless explosion combustion (SEC) is a recently proposed concept aiming for pressure gain combustion through an unsteady process of multiple, distributed autoignitions occurring simultaneously. For this, a stratified fuel profile of dimethyl ether is injected into a continuous air flow.

Advanced Science, Volume 13, Issue 3, 14 January 2026.Interrupting the air supply during the operation of solid oxide fuel cells leads to irreversible chemical degradation of the cathode materials, primarily driven by strontium at the A‐site of perovskite structures. Alternative strontium‐free materials effectively address this issue, ensuring high performance and reliable operation during operational ...

Assessment of Life Safety Risk in Building Fires With an Integrated Fire and Evacuation Model
Discrete Dynamics in Nature and Society, Volume 2026, Issue 1, 2026.This paper presents an integrated simulation methodology that combines fire hazard modeling with pedestrian evacuation analysis to evaluate how tenability conditions affect occupant egress. In the proposed approach, fire scenarios representative of leisure and spa resorts are modeled using the Fire Dynamics Simulator (FDS).
