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.
Claims20
An internal combustion engine comprising:
- a cylinder;
- a piston located within said cylinder, said piston being configured to move between a top-dead-center (“TDC”) configuration and a bottom-dead-center (“BDC”) configuration, thereby defining a stroke of said piston;
- a central protuberance extending from a top surface of said piston;
- and
- a cylinder head enclosing said piston within said cylinder, thereby defining a combustion chamber, said cylinder head defining a central recess for receiving said central protuberance when said piston is at the TDC configuration,
- wherein said combustion chamber is divided into a primary chamber and a secondary chamber when said central protuberance is received by said central recess.
An internal combustion engine comprising:
- a cylinder;
- a piston located within said cylinder, said piston being configured to move between a top-dead-center (“TDC”) configuration and a bottom-dead-center (“BDC”) configuration, thereby defining a stroke of said piston;
- a protuberance extending from a top surface of said piston;
- and
- a cylinder head enclosing said piston within said cylinder, thereby defining a combustion chamber, said cylinder head defining a recess for receiving said protuberance when said piston is at the TDC configuration,
- wherein said combustion chamber is divided into a primary chamber and a secondary chamber when said protuberance is received by said recess.
An internal combustion engine comprising:
- a cylinder;
- a piston located within said cylinder, said piston being configured to move between a top-dead-center (“TDC”) configuration and a bottom-dead-center (“BDC”) configuration, thereby defining a stroke of said piston;
- a cylinder head enclosing said piston within said cylinder, thereby defining a combustion chamber;
- and
- a first valve associated with said combustion chamber,
- wherein said first valve is configured to facilitate heat transfer away from a hot spot within said combustion chamber.
The engine of claim 20, further comprising second and third valves, said first valve being located along a centerline of the engine and said second and third valves being located on respective opposing sides of the engine, each of said third and fourth valves being offset from said centerline.
