Abstract: A piston and combustion chamber including piston crown grooves extending from the combustion bowl, promoting swirl and mix within the compressed atmospheric air/gases made up of 78% nitrogen along with 20% oxygen locked in the bowl into an ideal mix with the introduced fuel forming into an ideal charge trapped in the bowl of the piston crown improve thermal efficiencies by overcoming erratic, incomplete and improper combustion resulting in lower emissions that can prevent environmental damages due to pollution from UHC, CO, NOx, soot with the least carbon dioxide formations when using carbon rich fuels such as diesel engine operations under full load.

Abstract: A combustion chamber design layout of grooves or channels or passages formed in the squish band to further enhance turbulence in the charge prior to ignition as compared to existing designs with squish bands or hemispherical layouts in I.C. Engines. These grooves or channels or passages after ignition direct the flame front to cause multipoint ignition during the combustion cycle resulting in the following distinct advantages over existing designs in practice. First, quicker and complete clean burn combustion; second, lower operating temperatures due to the higher flame velocities; third, enhanced torque and power through the entire range resulting in better fuel economy with lower Emissions; and fourth, smoother engine operation through the entire range enhancing engine life.
