摘要：Internal combustion engines in now a days is the best available reliable source of power for all domestic,large scale industrial and transportation applications. The major issue arises all the efficiency of these engines. Everyattempt made to improve these engines tends to attain the maximum efficiency.The study is about the effects of airswirl in the cylinder on its performance.The performances of the diesel engines are enhanced by proper design of inletmanifold, exhaust manifold, combustion chamber, piston etc. The study is about the effect of piston configurations onin- cylinder flow.By changing the piston crown design the enhancement in the turbulence inside the cylinder isachieved. Also grooves are made to achieve the increase in the swirl intensity for better mixing of fuel and air.SwirlVelocities in the charge can be substantially increased during compression by suitable design of the piston. In thepresent work, a study on the effect of different piston configuration on air motion and turbulence inside the cylinder ofa Direct Injection (DI) diesel is carried out using Computational Fluid Dynamics (CFD) code Star CCM+.
