  • Piston and engine system using same
    Patent number: 12146452
    Abstract: A piston for an internal combustion engine includes a piston skirt and a piston crown attached to the piston skirt. The piston crown includes a combustion face forming a piston rim extending circumferentially around a piston center axis, and a combustion bowl. The combustion face further forms a bowl edge defining an intersection of the combustion bowl and the piston rim, and includes a reentrant surface extending between the bowl edge and a bowl outer wall. A ratio of a bowl max dimension to a bowl opening dimension is from about 1.10 to about 1.15.
    Type: Grant

  • Piston optimized for combustion flame speed and compression ratio in engine system
    Patent number: 12037961
    Abstract: A piston for an internal combustion engine includes a piston skirt and a piston crown attached to the piston skirt and including a combustion face. The combustion face forms a piston rim and a combustion bowl. A bowl edge defines an intersection of the combustion bowl and the piston rim, and a reentrant surface defining a reentrancy angle extends between the bowl edge and a bowl outer wall. A ratio of a bowl depth dimension coincident with the piston center axis to a compression height dimension coincident with the piston center axis is from about 0.30 to about 0.35.
