Abstract
The invention relates to an internal combustion engine comprising a combustion cylinder housing a combustion piston, a compressor cylinder housing a compressor piston, an expander cylinder housing an expander piston, and a crankshaft connected to the combustion piston and the expander piston by a respective connecting rod. The internal combustion engine further comprises a connecting element rigidly connecting the compressor piston and the expander piston such that the compressor piston and the expander piston move in unison.
Claims18
An internal combustion engine comprising:
- at least one combustion cylinder housing a combustion piston, said combustion cylinder being configured to be energized by forces of combustion;
- a compressor cylinder housing a compressor piston, said compressor cylinder being configured to compress a volume of air and transfer the compressed air to the at least one combustion piston;
- an expander cylinder housing an expander piston, said expander cylinder being configured to receive exhaust gases from the at least one combustion piston;
- a crankshaft connected to said at least one combustion piston and said expander piston by a respective connecting rod, characterized in that the internal combustion engine further comprises a connecting element rigidly connecting said compressor piston and said expander piston such that the compressor piston and the expander piston move in unison.
