摘要

This paper presents a combined solution for improving the performances of the automotive spark ignition engine. The first way develops a variable sequential ratio throughout its functioning thermodynamic cycle. Using this process, we are trying to obtain a closer approach to the ideal constant volume combustion cycle, specific to the spark ignition engine, and thus improving the engine efficiency and lowering the fuel consumption and pollution level. The second way, concern the architecture of the compression ring. The theoretical model we have developed allows the determination of a new transversal profile of the compression ring in order to obtain a better lubrication conditions to lower friction ware and increase the mechanical efficiency of the piston ring - cylinder line coupling. This paper contains a study regarding the both modification of these parameters in various situations, aiming at the optimization of this engine solution and at the establishment of the best constructive solution.
