Piston and process for achieving controlled ignition and combustion of hydrocarbon fuels in internal combustion engines by generation and management

Patent ·
OSTI ID:6966547
This patent describes an improvement in a piston for a reciprocating piston internal combustion engine in which a combustion cycle is carried out in a variable volume combustion chamber defined by the piston reciprocating in a close ended cylinder into which a fuel and air charge is periodically supplied. The cycle includes intake, compression, combustion, expansion and exhaust portions. The piston crown is recessed and contains the majority of the charge when the combustion chamber is at minimum volume.
