Experimental Analysis of Single Cylinder 4-Stroke Diesel Engine for the Performance and Emission Characteristics at Different Inclinations of the Intake Manifold




Intake Manifold Orientation, Single Cylinder 4- stroke Diesel Engine, In-Cylinder flow-field structure.


In the present days, most of the countries over the world wide have enforced the strict emission norms in order to reduce emission levels from the engine exhaust to curb the problem of pollution. The main problem in connection with the combustion in C.I. engine is the intimate mixing of fuel injected and air. Air motion in CI engine influences the atomization and distribution of fuel injected in the combustion chamber and also supplies fresh air to the interior portion of the fuel drops and thereby ensures complete combustion. The design and orientation of the Intake Manifold has a major influence on the air flow- field generated within the Diesel Engine Cylinder which in turn directly influence the Performance and Emissions characteristics of the engine. In this present work, the orientation of the Intake Manifold was changed by inclining it at several different angles viz. Normal Intake Manifold, Intake Manifold at 25° inclination, 50° inclination and 75° inclination w.r.t. Normal Intake Manifold Position and then the effects of these different orientations of the Intake Manifold on the Performance and Emission parameters of the Single Cylinder 4-Stroke naturally aspirated Diesel Engine were analyzed and then comparisons of the computed results were made with those of the Normal Intake Manifold. From the experimental research work, it is found that the BSFC reduces, brake thermal efficiency increases and there is an improvement in the exhaust gas emissions as orientation of the Intake Manifold is changed from Normal Manifold Position to 50° inclination w.r.t. Normal Manifold Position.
