ABSTRACT:
A spark-ignition type internal combustion engine having a precombustion chamber auxiliary to the variable volume space in the engine cylinder between the piston and cylinder head. Fuel injected into air in the chamber and fuel-laden air initially entering this chamber from the variable volume space, pursuant to the compression stroke of the piston, form a mixture compressed into a discrete reliably spark-ignitable air-fuel mass within a portion of the chamber where such mass envelops igniter electrodes. A vestibule portion of the chamber causes air, or air mixed with fuel in quantity determinative of engine power output, forced from said space to enter the chamber in a manner compressing and retaining the air-fuel mass in its enveloping relation with the electrodes until ignition occurs.
