TURBOCHARGER MATCHING FOR TWO CYLINDER CONSTANT SPEED DIESEL ENGINE WITH UNEVEN FIRING ORDER

The major challenge that is faced by most of the engine manufacturers nowadays is to meet the stringent emission norms with least modification in the engine design. In achieving the emission norms simplicity of the design has to be maintained as far as possible by optimizing the available emission control techniques. This project deals with such optimal technique with reduced cost to meet CPCB II in minimum time with minimum design changes. In this work, Turbocharger matching is done for an uneven firing order Engine that involves the selection of compressor and turbine based on the airflow requirements to meet the required performance and emission. The major challenge is to match the turbocharger for uneven firing order engine where the exhaust flow rate will have pulsation effect. In spite of variations in the exhaust flow, Airflow variation from Turbocharger is kept within 10 kg/h.
