Inhibition of autoignition at high pressure

Combustion and Flame, 1973
Induction periods have been measured for the autoignition of three alkane fuels as ignited {fx222-01} and pressures close to 720°K and 2.0 MN m2 in the presence of various concentrations of these {fx222-03} itors. The inhibitors produce the same pattern of behaviour as that reported previously for {fx222-04} by hydrogen, deuterium and carbon monoxide ...

Short communication: Autoignition temperature of trichlorosilanes

Fire and Materials, 2002
AbstractTrichlorosilanes are important silicon intermediates used to manufacture silicone materials. Because they are produced and used in large quantities and some are very reactive, it is important to determine the autoignition temperature (AIT) of trichlorosilanes.

Evolution of sensitivity directions during autoignition

Proceedings of the Combustion Institute, 2019
Abstract Sensitivity analysis of the ignition delay time and species profiles to kinetic parameters has been widely used to identify the rate-limiting steps during the autoignition process, providing insights for the optimization of the reaction mechanism.

Autoignition of propane behind shock waves

Russian Journal of Physical Chemistry B, 2015
The ignition delay times of C3H8-O2-Ar mixtures of various compositions are measured behind reflected shock waves at temperatures of 1220–1750 K and a pressure of (0.65 ± 0.05) MPa. A kinetic mechanism of propane ignition based on the known rate constants of the key elementary reactions is developed.

Autoignition behavior of practical fuels

2018
Spark ignition (SI) and compression ignition (CI) engine fuels are characterized by standards developed in 1927 and 1932, respectively. Over the course of these years, modern engines have drastically changed their operating conditions; however, these fuel indexes are still used today with no significant change to their definition.

Autoignition characteristics of aircraft-type fuels

Combustion and Flame, 1982
The ignition delay characteristics of Jet A, JP 4, no. 2 diesel, cetane and an experimental referee broad specification (ERBS) fuel in air at inlet temperatures up to 1000 K, pressures of 10, 15, 20, 25 and 30 atm, and fuel air equivalence ratios of 0.3, 0.5, 0.7 and 1.0 were mapped.

Numerical studies on autoignition and detonation development from a hot spot in hydrogen/air mixtures

Combustion theory and modelling, 2019
Detonation development inside spark ignition engines can result in the so called super-knock with extremely high pressure oscillation above 200 atm. In this study, numerical simulations of autoignitive reaction front propagation in hydrogen/air mixtures ...

Modeling cyclic dispersion in autoignition combustion

IEEE Conference on Decision and Control and European Control Conference, 2011
A two-state discrete-time model is developed for the cycle-to-cycle dynamics in lean-fueled controlled autoignition engines. The main goal is to capture the cyclic variability in the combustion phasing which is a key performance variable in combustion control.

Autoignition of ethylene in shock waves

Russian Journal of Physical Chemistry B, 2010
The delay time of ignition of various C2H4-O2-Ar mixtures behind reflected shock waves were measured at temperatures of 1090–1520 K and a pressure of 0.65 ± 0.05 MPa. A kinetic scheme of the ignition of ethylene based on the known rate constants of the key elementary reactions was developed.
