Air pollution is one of the major issues about the diesel engines in todays' world. It is a special concern in those areas that have difficulty meeting health-based outdoor air quality standards. Natural gas has low emission and resource abundance and also conventional compression ignition engine can be easily converted to a dual fuel mode to use natural gas as main fuel and diesel as pilot ...

In this article, the effects of heated ethanol diesel blend on emissions were investigated experimentally. Additionally, effect post-injection strategies in AVL Boost model engine, which has same characteristics as experimental engine running with ethanol-diesel emulsion fuel, was a simulation. special designed mixer, (E10) formed 10% and 2% isopropyl stirred at 40 °C. The temperature kept cons...

This study investigates how high levels of exhaust gas recirculation (EGR) combined with certain fuel injection strategies and energy recovery systems affect diesel engine emissions and fuel economy. The key test apparatus was a John Deere 4.5L diesel engine which was modeled using the computer-based engine simulation tool GT-Power. The conclusion was made that utilization of high EGR levels (3...

• Adding CeO 2 nanopowder and CNT as fuel additives leads to reduced emissions. Fuel reduce the penetration of DF during injection at low ambient pressure. increases GTL after injection. Higher pressure or temperature a increased average cone angle. Penetration reduces with growing This work aims experimentally investigate demonstrate impacts using Cerium Oxide (CeO ) multi-wall carbon nanotube...

This study investigated the effects of high exhaust gas recirculation (EGR) rates on dimethyl ether (DME) fuel combustion performance, exhaust emissions and particle emission characteristics in a small direct injection diesel engine under various injection timings. To examine the effect of EGR and injection timings, the experiment was performed under high EGR rates (0%, 30%, 50%) and injection ...

Air-borne acoustic based condition monitoring is a promising technique because of its intrusive nature and the rich information contained within the acoustic signals including all sources. However, the back ground noise contamination, interferences and the number of Internal Combustion Engine ICE vibro-acoustic sources preclude the extraction of condition information using this technique. There...

Lignocellulosic materials have been identified as potential carbon–neutral sources of sustainable power production. Catalytic conversion of lignocellulosic biomass results in liquid fuels with a variety of aromatic molecules. This paper investigates the combustion characteristics and exhaust emissions of a series of alkylbenzenes, of varying number of methyl branches on the monocyclic aromatic ...

An advanced numerical investigation has been carried out in order to study the effect of multiple injection strategies on Caterpillar heavy-duty diesel engine emissions. Both different injected fuel percentages for each pulse and several dwells between main and post phase were investigated via computational fluid dynamics (CFD) and large eddy simulation (LES). Two sets of simulations were taken...

Biodiesel is one of the most promising renewable, alternative and environmentally friendly biofuels that can be used in diesel engine without any need for any modification in the engine. However, researchers have reported that the engines running with biodiesel emit NOx in higher concentrations. To address this problem, in the present study an experimental investigation has been carried out on ...
