Research ArticleOpen accessIn the abstractThe Effect of Spring Design as Return Cycle of Two Stroke Spark Ignition Linear Engine on the Combustion Process and PerformanceA. Z.M. Fathallah, R. A. BakarProblem statements: The effects of optimization on spring design of the linear engine with spring mechanism in its performance and combustion process have been examined. However, at certain conditions the engine can not work properly as predicted. This can happen because displacement of engine stroke is depending on thrust forces of combustion process in cylinder of the engine. For that, … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,512 accessesView PDFCite
