Performance Analysis of Ci Diesel Engine Using Swirl Concept at Inlet Manifold

Abstract

The depletion of fossil fuels and pollution caused by its emissions instigated the researchers to conserve the fossil fuels and regulate the emissions. The control of emissions is achieved by efficient combustion which is possible by uniform mixing of air and fuel in the cylinder. The objective of the present study is to enhance the swirl motion effect in the cylinder which causes better performance and reduce the emissions. The swirl motion in the engine can be generated by modifying three parameters viz., the configuration of the cylinder head, the piston crown, and the inlet manifold. In this thesis to create effective swirl motion in the engine, a fresh air fan is placed at the intake manifold.

In this, the experiment is carried out on the four-stroke single cylinder water cooled diesel engine using diesel, biodiesel blends with the standard piston, 100 microns and 200-micron thermal barrier coated pistons. The thermal barrier coating is done on the piston crown. The performance, emission and combustion parameters with swirl motion are analysed and compared without swirl motion results.
