The depletion of fossil fuels and its emissions prompted the researches to conserve the fossil fuel and their controlled combustion. In this connection to achieve the said condition one of the operation parameters like in cylinder Air flow motion has considered. Hence, in the present work the experimental Analysis has been carried out to study the impact of in cylinder swirling flow using both fossil and renewable fuels. For this, the experiment is carried out on the four stroke single cylinder water cooled diesel engine using both diesel and biodiesel fuels with varied piston geometry. In this work an attempt is made using hemispherical piston bowl and flat piston without any change in clearance volume. The swirl motion is created by modifying the inlet manifold. The performance and emission characteristics obtained are presented in the results
