INTERNAL COMBUSTION ENGINE WITH AUXILIARY COMBUSTION CHAMBER

摘要

An internal combustion engine of the type having a relatively large main combustion chamber supplied with a lean mixture through a main inlet passage and a relatively small auxiliary combustion chamber supplied with a rich mixture through an auxiliary inlet passage, the auxiliary combustion chamber being in communication with the main combustion chamber through a torch nozzle. Means are provided for igniting the rich mixture to cause a flame to project through the torch nozzle to burn the lean mixture in the main combustion chamber. The main and auxiliary passages are throttled are supplied respectively through a relatively large main venturi passage and a relatively small auxiliary venturi passage, and wherein the effective area of the torch nozzle is greater than that of the auxiliary venturi passage.
