An Experimental Approach to the Controlled Auto-Ignition
SAE Technical Paper Series, 2007<div class="htmlview paragraph">Auto-ignition may be considered as the ultimate combustion process for vehicle engines. Regarding combustion control, ignition timing and heat release are the chief concerns. The former is finding a solution, however the latter has, as yet, several approaches.</div> <div class="htmlview paragraph">As a ...

External heating of electrical cables and auto-ignition investigation
Journal of Hazardous Materials, 2017Electric cables are now extensively used for both residential and industrial applications. During more than twenty years, multi-scale approaches have been developed to study fire behavior of such cables that represents a serious challenge. Cables are rather complicated materials because they consist of an insulated part and jacket of polymeric ...

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.

The Auto-Ignition of Multicomponent Fiber Systems
1973Using a simple experimental procedure for determining the time until ignition after a material is plunged into a heated air environment, it is possible to obtain kinetic data for this auto-ignition process. Results on homogeneous polymeric materials show that, while the rate controlling factors in every case are physical rather than chemical, ignition ...

Modeling and Simulation of Gasoline Auto-Ignition Engines
IFAC Proceedings Volumes, 2009Abstract Both the customer demand for increasing mobility and the emission legislation lead to a challenge for engine researchers and developers in order to reduce emissions and fuel consumption. One approach that is presently under extensive investigation is to implement auto-ignition combustion in gasoline engines.

Auto-ignition synthesis of nanocrystalline BaTi4O9 powder
Journal of Materials Chemistry, 2001Monophasic BaTi4O9 powder has been prepared by an auto-ignition route. The auto-ignition of the gel, prepared by thermal dehydration of a pH adjusted citrate–nitrate solution, directly resulted in voluminous BaTi4O9 powder with traces of carbonaceous material.

SOC Detection of Controlled Auto-Ignition Engine
SAE Technical Paper Series, 2007<div class="htmlview paragraph">Controlled Auto-Ignition (CAI) combustion is a new combustion concept. Unlike the conventional internal combustion engine, CAI combustion takes place homogeneously throughout the fuel/air mixture with self ignition, and the mixture is burned without flame propagation.

Unburnt Mixture Auto-Ignition Prediction
2018As it is commonly assumed that knock occurs because of local auto-ignition(s) in the unburnt mixture, Sections 2.1.2 and 2.3.2 the accurate prediction of auto-ignition is the key to developing a fully predictive knock model for the 0D/1D engine simulation.

Auto-Ignition Temperature Data for Selected Ketones
Advanced Materials Research, 2012Auto-ignition temperature (AIT) is usually defined as the lowest temperature at which a substance will produce hot-flame ignition in air at atmospheric pressure without the aid of an external energy source such as spark or flame. Its principal applications include: defining the maximum acceptable surface temperature in a particular area, usually for ...

CFD modelling of cyclohexane auto-ignition in an RCM
Fuel, 2012Abstract The kinetic modelling of cyclohexane auto-ignition in a rapid compression machine is addressed, based on the comprehensive kinetic mechanism, comprising 499 species and 2323 reactions, then reduced to 56 species involved in 196 reactions and 50 species involved in 143 reactions.
