Abstract
A piston can include a piston body formed of a first portion and a second portion. The second portion can include a crown and an outer wall having a perimeter defined by a first circle overlapping with a second circle. The piston can be included in an internal combustion engine and configured as a primary piston, an added piston, or both.
Claims29
1-28. (canceled)
An internal combustion engine comprising:
- a block defining a primary bore;
- a housing at least partially defining a first added bore, the housing coupled to the block;
- a crankshaft configured to rotate within a passage at least partially defined within the block;
- a crosshead connected to the crankshaft by a first connecting rod;
- a primary piston capable of reciprocating within the primary bore between top dead center and bottom dead center, the primary piston coupled to the crosshead and positioned on a first side of the crosshead;
- and
- a first added piston capable of reciprocating within the first added bore between top dead center and bottom dead center, the first added piston coupled to the crosshead and positioned on a second side of the crosshead, the second side opposite the first side.
