Abstract

An internal combustion engine includes a first low-pressure cylinder housing a first low-pressure piston, and a first high-pressure cylinder housing a first high-pressure piston, the first high-pressure cylinder being arranged in upstream fluid communication with the first low-pressure cylinder for providing exhaust gas into the first low-pressure cylinder. The internal combustion engine further includes a second low-pressure cylinder housing a second low-pressure piston, the second low-pressure cylinder being arranged in upstream fluid communication with the first high-pressure cylinder for providing compressed gas into the first high-pressure cylinder, and a second high-pressure cylinder housing a second high-pressure piston, the second high-pressure cylinder being arranged in downstream fluid communication with the first low-pressure cylinder for receiving compressed gas from the first low-pressure cylinder, and further arranged in upstream fluid communication with the second low-pressure cylinder for providing exhaust gas into the second low-pressure cylinder.
