Abstract
Nozzle arrangements for injecting fuel into a combustion chamber of a piston engine with stratified charge being provided by a resilient diaphragm which deflects by amounts proportional to engine load. At high engine load, further deflection of the diaphragm effects a deep penetration charge for improved performance and economy. Between pulses, the diaphragm effectively closes off the nozzle so that sac volumes of the nozzle are minimized along with discharge of hydrocarbons into the combustion chamber on blowdown.
