Abstract
A jet ignition internal combustion engine of the type provided with separate induction passages for lean and rich air-fuel mixtures wherein the main inlet valve mounts a cup like member forming an auxiliary ignition chamber within the main combustion chamber. The rich mixture is supplied to the auxiliary chamber through the hollow stem of the main inlet valve, flow being controlled by a small auxiliary valve within the main valve and actuated by the same valve gear. Openings in the wall of the valve-carried ignition chamber connect with spark ignition means and with the main combustion chamber to provide for spark ignition of the rich ignition chamber mixture and resultant jet ignition of the lean mixture in the main combustion chamber.
