Research ArticleOpen accessAn Investigation of Valve Lift Effect on Air Flow and Coefficient of Discharge of Four Stroke Engines Based on ExperimentAbdul Rahim Ismail, Rosli Abu Bakar, SeminThe coefficient of discharge (CD) is defined as the ratio of actual discharge to ideal discharge. In an engine environment, ideal discharge considers an ideal gas and the process to be free from friction, surface tension, etc. Coefficients of discharge are widely used to monitor the flow efficiency through various engine components and are quite useful in improving the performance … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 7,434 accessesView PDF Cite
