Radiant Auto-Ignition of Wood

, 2001
Although piloted-ignition is well studied, auto-ignition is not, and under some conditions the latter may initiate the former. For that reason, the dynamics and mechanisms in the auto-ignition of redwood by radiant heating were experimentally studied. An open-cone radiant source heated an insulated cubical vertical sample 4 cm on a side.

Controlled auto-ignition

ATZautotechnology, 2007
Gasoline HCCI, also called Controlled Auto-Ignition (CAI), allows for significant efficiency gains in combination with extremely low NOx emissions when compared to conventional spark-ignited combustion concepts. Bosch’s option to combine a lean-operating direct-injection engine with a simple exhaust gas aftertreatment system (three-way catalytic ...

On the regimes of auto-ignition in a turbulent medium

Applied Scientific Research, 1993
The process of auto-ignition in a non-premixed, homogeneous and isotropic turbulent medium is considered. The governing pdf transport equation is simulated via a Monte Carlo method. It is found that the pdf evolution depends on the relative magnitudes of two time scales, namely, that of turbulent mixing and of chemical reaction. Calculations made for a

Stochastic simulation of hydrogen–oxygen auto-ignition at the microscale

The Journal of Chemical Physics, 2023
A hybrid stochastic simulation method is developed to study H2–O2 auto-ignition at the microscale. Simulation results show that the discrete and stochastic characteristics of reaction collisions have notable impacts on the ignition process, particularly in the early stages when only a few radicals exist.

The auto-ignition temperature of methane

Journal of Hazardous Materials, 1984
Abstract An improved method for measuring auto-ignition temperatures of gaseous fuels has been developed. Results are reported for methane—air mixtures and compared with previous work. It appears that the normally accepted minimum auto-ignition temperature for methane of 537 (or 540)°C was theoretically rather than experimentally derived.

The effects of intake backflow on in-cylinder situation and auto ignition in a gasoline controlled auto ignition engine

Applied Energy, 2013
Abstract The inability to control the auto ignition in CAI combustion is an obstacle against its practical use, and the in-cylinder thermal and component distributions are being investigated in more depth as a way to control auto ignition. A 3D simulation using KIVA code is applied to study the effects of intake backflow on the in-cylinder situation.
