The impact of fuel injection pressure on the development diesel flames has been studied in a light-duty optical engine.Planer laser-induced fluorescence imaging (fuel-PLIF) and hydroxyl radicals (OH-PLIF) as well line-of-sight integrated chemiluminescence cool-flame OH* were performed for three different common-rail pressures including 70, 100, 130 MPa.The timing injected mass held constant resulting earlier end higher pressure.The incylinder was also measured to understand bulk-gas...
The stringent regulations that were placed on gasoline vehicles demand significant improvement of the powertrain unit, not only to become cleaner but also more efficient. Therefore, there is a strong need understand complex in-cylinder processes will have direct effect combustion quality. This study applied multiple high-speed optical imaging investigate interaction between flow, spark, flame, and performance. These individual elements been studied closely in literature combined well...
Influence of the injection pressure on temporal evolution lifted jet flame base upon bowl wall impingement has been studied in a small-bore optical diesel engine.Previous studies suggest that jet-wall interaction causes reentrainment combustion products into incoming jet, which shortens lift-off length during and thereby increasing downstream soot.After end injection, slowly moves as diminishing momentum results reduced re-entrainment.How impacts this transient behaviour is main focus...
Among multiple factors that affect the quality of combustion, intricate and complex interaction between in-cylinder flow/turbulent field flame propagation is one most important. In this study, true simultaneous, crank-angle resolved imaging front measurement flow-field was achieved by application high-speed Particle Image Velocimetry (PIV). The technique successfully implemented to avoid problems commonly associated with PIV in a combustion environment, such as interferences reflections,...
In this paper, numerical simulations of an automotive-size optical diesel engine have been conducted employing the Reynolds-Averaged Navier-Stokes (RANS) equations with standard k- turbulence model and a reduced n-heptane chemical mechanism implemented in OpenFOAM.The current paper builds on previous work where has validated for same using diagnostic data.The present study investigates numerically influence different operating conditions -relevant modern engines -on mixture formation...
The current gasoline engines are being pushed by researchers as well the manufacturers to meet with stringent demands and regulations regarding its efficiency, fuel economy harmful emissions. Ultra-lean burning accompanied higher turbulence flow level currently best options for these successfully criteria. This study explores turbulent flame structure inside an real operating engine environment in attempt improve knowledge base of this area hence provide useful information developers,...
The present study explores the effect of in-cylinder generated nonthermal plasma on hydroxyl and soot development.Plasma was using a newly developed Microwave Discharge Igniter (MDI), device which operates based principle microwave resonation has potential to accentuate formation active radical pools as well suppress while stimulating oxidation.Three diagnostic techniques were employed in single-cylinder small-bore optical diesel engine, including chemiluminescence imaging electronically...
