The Influence of Swirl on Performance Characteristics of Diesel Engine Using Biodiesel Blends

Abstract

Diesel engines combustion quality is predicated on the formation of fuel-air amalgamation. The in-cylinder air kineticism in internal combustion engines is one of the most consequential factors controlling the combustion process of CI engine and emissions can be controlled by engendering turbulence, by designing intake system, by designing combustion chamber. A good swirl promotes expeditious combustion to amend the efficiency.

In the present context, the world is confronted with the twin crisis of fossil fuel and environmental degradation. The fuel economy is achieved by efficient combustion inside the cylinder which is possible by uniform commixing of air and fuel in the cylinder. The fuel injection pressure and the swirl kineticism have a great impact on efficient combustion.

The objective of the present study is to enhance the swirl effect in the cylinder which causes better performance and reduces the emissions. In this work an endeavor is made on D.I Diesel engine with grooved piston fuelled with pine oil coalesced with diesel in sundry proportions.
