ABSTRACT:
Internal combustion reciprocating-piston engine precombustion chamber in which a mass of air or air mixed with selective amounts of fuel and a spark-ignitable air-fuel mass are segregatively compressed with the latter mass enveloping spark electrodes preparatory to ignition. The chamber is provided by recessing the air intake valve of an engine cylinder into the cylinder head so that this chamber forms a section of the main air intake passage for the cylinder. Air deflecting means is provided in a vestibule of the chamber in a manner to create a vortex of air forced from the cylinder through the vestibule internally of the chamber pursuant to the compression stroke of the cylinder's piston, and, without incurring significant resistance to the flow of air delivered through the air intake passage into the cylinder pursuant to the preceding air intake stroke of the piston.
