The design and development of modern internal combustion engines is marked by a reduction in exhaust gas emissions and increase in specific power and torque. Correspondingly, combustion noise excitation and fuel consumption also have to be reduced. These objectives can be achieved through the development of advanced combustion systems, the increased flexibility of fuel injection systems and ECU...
The aim was to identify relationships between combustion conditions, particle characteristics, and optical properties of fresh and photochemically processed emissions from biomass combustion. The combustion conditions included nominal and high burn rate operation and individual combustion phases from a conventional wood stove. Low temperature pyrolysis upon fuel addition resulted in "tar-ball" ...
Catalytic combustion is generally accepted as an environmentally preferred alternative for the generation of heat and power from fossil fuels mainly due to its advantages related to the stable combustion under very lean conditions with low emissions of NOx, CO, and UHC at temperatures lower than those occurred in conventional flame combustion. Despite these advantages, the commercial applicatio...
Energy transfer in a pulsed-microwave enhanced flame is investigated using hybrid fs/ps coherent anti-Stokes Raman scattering (CARS) to monitor both vibrational and rotational temperatures of nitrogen an atmospheric pressure laminar premixed natural gas/air stagnation flame. Temperatures were measured throughout the structure following 30-kW peak power, 2 ?s duration, 3 GHz microwave pulse reso...
homogeneous charge compression ignition (hcci) combustion is a pioneer method of combustion in which pre-mixed fuel and oxidizer (typically air) are compressed to the point of auto-ignition. hcci engines can operate with most alternative fuels, especially, dimethyl ether (dme) which has been tested as a possible diesel fuel due to its simultaneously low nox and pm emissions. in this paper a sin...
Briquettes are solids that generally made from agricultural waste materials. Char briquettes one of the alternative energies for daily needs. This study used char palm shell and LDPE microwave-assisted co-pyrolysis at 450 Watts. The were product Low-Density Polyethylene (LDPE) with variations in composition 0:100, 50:50, 100:0 pressure 50 kg/cm2, 100 150 200 kg/cm2. In this research, thermograv...
This work communicates cavity ring-down spectroscopy (CRDS) of methylidyne (CH) in a chemiluminescent plasma that is produced microwave cavity. Of interest are the rotational lines 0-0 vibrational transition for A–X band and 1-0 B–X band. The reported investigations originate from research on CH radical 1996, which constituted first case applying CRDS to radical. report also includes recent ana...
