Research ArticleOpen accessAll words, across the recordA Design Strategy for Volumetric Efficiency Improvement in a Multi-cylinder Stationary Diesel Engine and its Validity under Transient Engine OperationP. Seenikannan, V.M. Periasamy, P. NagarajThis paper proposes an approach to improve engine performance of volumetric efficiency of a multi cylinder diesel engine. A computer simulation model is used to compare volumetric efficiency with instantaneous values. A baseline engine model is first correlated with measured volumetric efficiency data to establish confidence in the engine model's predictions. A derivative of the baseline model with exhaust manifold, … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 7,502 accessesView PDF Cite
