Design of Test Rig for Swirl Measurement in I.C. Engine

This paper gives the overall view of the swirl measuring techniques and its importance in the efficient combustion. The measurement techniques comprise of types, industrial development and research analysis. In the field of industrial development paddle wheel anemometer technique is best suitable. Angular momentum transfer is created in this test rig which resembles the actual conditions of the working engine for same valve lift. A common technique for characterizing the swirl within the cylinder has been to use light paddle wheel pivoted on the cylinder centerline with low friction bearings. The rotation rate of the paddle wheel is used for measurement of air swirl since this rotation rate depends on the location of wheel and its design and the details of the swirling flow. This technique has been outdated by the impulse swirl meter. Swirl Assists the engine design team in port design development and optimization of port for new development projects for cleaner and efficient technologies.
