Emission Characteristics of Single Cylinder CI Engine for Varying Nozzle Depth at Different Spray Angles

Abstract

The present research is about the reduction of harmful gases from the exhaust of a diesel fuel operated diesel engine. A kirloskar single cylinder diesel engine (model –TV-1) is selected for the numerical simulation using commercially available software AVL FIRE. The operating and boundary condition of single cylinder diesel engine is referenced in the published articles. The hemispherical bowl piston geometry is generated and meshed in the software the research is further processed with the selection of three different spray angles like 120o , 140o , and 160o . Whereas 120 spray angle is the standard spray angle. Additionally to analyzed the effect of nozzle depth on the emission, combustion and performance parameters four nozzle depth values are also included in the research. The four nozzle depths are 0.5mm, 1mm, 1.5mm and 2mm. whereas 1mm nozzle depth is standard nozzle depth. All four nozzle depths are examined under 120o , 140o , and 160o spray angle. The need of petroleum fuels is increasing everyday despite of their speculation regarding the depletion of petroleum fuels. The petroleum fuels are categorized as suspicious element for human being due to its well known major harmful effects on the environment. The concern is that the need of petroleum fuel is increasing simultaneously with its price in the market. The researchers around the world are focusing either on the reduction of harmful effects which produced from the petroleum fuel or finding another a batter substitute of the petroleum fuel.
