ABSTRACT:
A number of embodiments of combustion chamber configurations for internal combustion engines as applied as power units for outboard motors. In each embodiment, the combustion chamber comprises a main open volume in which combustion is initiated and into which fuel is discharged by a fuel injection nozzle. An energy cell, of smaller volume, is disposed so as to receive some of the fuel discharged by the injection nozzle and for creating combustion at the end of the combustion cycle to cause a pressure increase that discharges a hot charge into the main combustion volume for completing combustion. The energy cell is formed from a ceramic material. Both two and four-cycle applications and variations of combustion chamber configurations are disclosed.
