NEW COMBUSTION SYSTEM IN THE THREE-VALVE STRATIFIED CHARGE ENGINE
Through continued research on the combustion system of the stratified charge engine, a new combustion system (named branched conduit system) was developed, which is able to further reduce exhaust emissions, HC and NOX, in particular with no adverse effect on fuel consumption under the wide range of engine operating conditions. In this paper, the construction of new combustion system and its characteristics including fuel consumption and exhaust emissions are described. In addition, the combustion process with or without the branched conduits is examined by the time-resolved measurements of gas pressure and temperature obtained in the main combustion chamber and observed with high-speed colored photography.
