Combustion chamber structure in engine

Abstract

Abstract PURPOSE:To make a combustion chamber perform stratified combustion so easily while aiming at improvement in charging efficiency at the time of high load, by adjoining a spark plug to the combustion chamber through between respective exhaust valves as well as adjoining a fuel injection nozzle to the combustion chamber through between these valves. CONSTITUTION:Respective suction valves 6 and 7 and exhaust valves 8 and 9 are all driven by a cam shaft 17 via swing arms 18 and 19. A spark plug 22 passes through between these exhaust valves 8 and 9 and its tip is adjoined to the vicinity of the central part of a combustion chamber 4. A fuel injection nozzle 23 passes through between these suction valves 6 and 7 and adjoins to the vicinity of the central part of the combustion chamber 4 as well. Thus, as aiming at improvement in charging efficiency at the time of high load, stratified combustion is made possible to be done so easily.
