This thesis shows the results of investigations about the combustion mechanisms of low-temperature premixed processes, in particular those in which only a partial homogenization of the fuel mixture is achieved, since they represent a realistic solution for commercial engine applications. Measurements has been carried out on a modern 6-cylinder diesel engine equipped with a rapid-prototyping ECU...

Gaseous emissions from the fluidised bed co-combustion of 50% w/w chicken litter and peat were monitored and recorded. Emission data were used to create a dispersion model for a proposed site on a poultry farm in Ireland. Variables within the combustion unit influenced both combustion and emission levels of pollutants such as SO(2) and NO(x), CO. Concentrations of atmospheric pollutants decreas...

The effect of switching between nonstiff and stiff methods on the efficiency of algorithms for integrating chemical kinetic. rate equations is presented, Different integration methods are tested by application of the packaged code LSODE to four practical combustion kinetics problems. The problems describe adiabatic, homogeneous gasPhase combustion reactions. It is shown that selective use of no...

By modulating engine valves to reinduct hot exhaust gas together with air and fuel, a clean and efficient form of autoignition can be created. Control of this combustion process, known as homogeneous charge compression ignition (HCCI), requires not only precise valve control but also a combustion control strategy that accounts for the cycle-to-cycle coupling through the exhaust. This paper outl...

The Soot Model Development Web Site (SMDWS) is a project to develop collaborative technologies serving combustion researchers in DOE national laboratories, academia and research institutions throughout the world. The result is a shared forum for problem exploration in combustion research. Researchers collaborate over the Internet using SMDWS tools, which include a server for executing combustio...

This paper describes an expanded mechanism of metal combustion that emphasizes reactions and phase changes occurring within the burning metal in addition to those occurring on and above the metal surface. Selected recent experimental work showing the importance of these internal processes in metal combustion is surveyed. Gas dissolution within the burning metal, ensuing phase changes, and their...

sol–gel auto-combustion is a unique combination of the combustion and the chemical gelation processes. in this work, nanosize (d) powders with compositions of znfe2o4 were synthesized by sol–gel combustion method. the puffy, porous brown powders as-combusted was calcined at the temperature of 750–1000◦c for 4 h. these powders are characterized by x-ray diffraction and scanning electron microsco...

Comment 1: “This article presents some interesting conclusions regarding the chemical mixing state of particles produced from the combustion of pulverised coal. It would be useful, however, to expand the discussion to cover differences between the single particle mass spectra reported here and those obtained for power generation-related coal combustion and domestic coal combustion in other prev...

It is shown that a conversion of neurons into strange quark matter in neutron stars is possible by means of a combustion process with a well-defined front. Conditions for the realization of a specific combustion mode, whether deflagration, detonation, or fast combustion, are discussed for several forms of the equations of state of neutron and strange matters.
