six stroke diesel engine - admin - 02-04-2014
[size=14.0pt]ABSTRACT[/size] In this report, a new six-stroke diesel engine is proposed and the thermodynamic performances of this engine are numerically and experimentally analyzed. Since the six-stroke diesel engine introduced here has two combustion processes in one cycle, it offers new methods of combustion control which can't be attained in an ordinary four-stroke diesel engine. In the analysis, we use a simple single zone thermodynamic model with considering the Wiebe's function for heat release rate and the Foschini’s equation for heat transfer coefficient. As a results, it was confirmed when the heat release of 1st combustion stroke and 2nd combustion stroke were equivalent, the maximum in-cylinder gas temperature was the lowest, and further it was lower than that of the four stroke diesel engine.
