Advanced Concepts for Controlled Combustion in Engines

Abstract

Studies carried out at the University of California, Berkeley, over a period of four years were concerned with fluid mechanical properties of turbulent pulsed jet plumes - systems that are of particular relevance to the initiation and control of combustion in engines. The eventual purpose of this program was to provide a rational background for a fundamental refinement of stratified charge diesel engines - the development of a combustion system where the formation of pollutants is minimized, fuel economy is maximized, while fuel tolerance is optimized. The results demonstrated that this goal is attainable by means of appropriate Pulsed Jet Combustion (PJC) generators. The exothermic process of combustion is executed thereby in the form of a fireball taking place in a stratified charge generated by turbulent plumes of a PJC system.
