Two Steps for an Environmental Friendly Propulsion Engine
Journal Title: Analele Universitatii "Dunarea de Jos" din Galati. Fascicula IX, Metalurgie si Stiinta Materialelor - Year 2011, Vol 34, Issue 2
Abstract
A logical way to preserve the natural resources and lowering the pollution level is the improving of the thermal engine efficiency in order to reduce the fuel consumption. Considering the weight factor of the spark ignition engine in automotive market, the authors propose a combined solution to improve the performances of this thermal engine. First, in order to improving the combustion efficiency, we are trying to obtain a closer approach to the ideal constant volume combustion cycle, specific to the spark ignition engine, by developing a variable sequential ratio engine. Secondarily, by modifying the architecture of the compression ring, the theoretical model developed allows the determination of a new transversal profile of the compression ring in order to obtain better lubrication conditions, to lower friction ware and increase the mechanical efficiency. This theoretical and experimental study regards the both modification of these parameters in various situations, aiming at the optimization of this environmental friendly propulsion engine.
