Abstract
Apparatuses, systems and method for utilizing multi-zoned combustion chambers (and/or multiple combustion chambers) for achieving compression ignition (and/or spark-assisted or fuel-assisted compression ignition) in an internal combustion engine are provided. In addition, improved apparatuses, systems and methods for achieving and/or controlling compression ignition (and/or spark-assisted or fuel-assisted compression ignition) in a “Siamese cylinder” internal combustion engine are provided.
Claims19
An internal combustion engine comprising:
- a cylinder;
- a piston located within said cylinder, said piston including a central protuberance;
- a cylinder head enclosing said piston within said cylinder, said cylinder head including a central recess associated with said central protuberance;
- and
- a valve located within said central recess;
- wherein said cylinder, cylinder head and central recess define a combustion chamber,
- wherein said central recess and said protuberance define primary and secondary chambers within said combustion chamber,
- wherein said primary and secondary chambers are in constant fluidic communication with each other during an entire stroke of said piston within said cylinder, and
- wherein compression ignition occurs within said primary chamber.
An internal combustion engine comprising:
- a cylinder;
- a piston located within said cylinder, said piston including a protuberance;
- and
- a cylinder head enclosing said piston within said cylinder, said cylinder head including a recess associated with said protuberance,
- wherein said cylinder, cylinder head and recess define a combustion chamber;
- wherein said recess and said protuberance define primary and secondary chambers within said combustion chamber,
- wherein said primary and secondary chambers are in constant fluidic communication with each other during an entire stroke of said piston within said cylinder, and
- wherein pressure ignition occurs within said secondary chamber.
An internal combustion engine comprising:
- a cylinder;
- a piston located within said cylinder, said piston including a central protuberance;
- a cylinder head enclosing said piston within said cylinder, said cylinder head including a central recess associated with said central protuberance;
- and
- a rod attached to said piston at a first location, said first location being determined based on a location of said central protuberance;
- wherein said cylinder, cylinder head and central recess define a combustion chamber having primary and secondary chambers, and
- wherein pressure ignition occurs within said secondary chamber.
An internal combustion engine comprising:
- a cylinder;
- a piston located within said cylinder;
- a cylinder head enclosing said piston within said cylinder;
- and
- a valve extending through said cylinder head at a location along a wall of said cylinder in which a hot spot is located,
- wherein said cylinder, cylinder head, and piston define a combustion chamber having primary and secondary chambers, and
- wherein pressure ignition occurs within said secondary chamber.
