The invention provides an internal combustion engine system () comprising&#x2014;at least one combustor (), and&#x2014;a first expander () arranged to receive exhaust gases from at least one of the at least one combustor (), and to expand and extract energy from the exhaust gases &#x2014;characterized in that the system comprises a second expander () arranged to receive exhaust gases from the first expander (), and to expand and extract energy from the exhaust gases.

Internal combustion engine system and a method for an internal combustion engine system

A method for controlling an internal combustion engine system, the engine system including a combustor arranged to receive air and fuel, and combust the received air and fuel, an expander arranged to expand exhaust gases from the combustion in the combustor and to extract energy from the expanded exhaust gases, and a communication valve arranged to control a communication between the combustor and the expander, including determining during operation of the engine system whether there is a pressure difference across said communication valve.

Method for controlling an internal combustion engine system

An internal combustion engine system includes at least one combustor, and a first expander arranged to receive exhaust gases from at least one of the at least one combustor, and to expand and extract energy from the exhaust gases, wherein the system includes a second expander arranged to receive exhaust gases from the first expander, and to expand and extract energy from the exhaust gases.

Internal combustion engine system and a method for an internal combustion system

An internal combustion engine system includes a compressor arranged to compress air, at least one combustor, at least one of the at least one combustor being arranged to receive the compressed air, and an exhaust treatment device arranged to process exhaust gases produced by at least one of the at least one combustor, a heat exchanger arranged to receive the compressed air from the compressor before it reaches the at least one of the at least one combustor, and wherein the heat exchanger is arranged to transfer heat from the compressed air to the exhaust treatment device.

Internal combustion engine system and an exhaust treatment unit for such a system

An internal combustion engine system includes at least one combustor, a compressor arranged to compress air, an air guide arranged to guide compressed air from the compressor to at least one of the at least one combustor, an expander arranged to expand exhaust gases from at least one of the at least one combustor and to extract energy from the expanded exhaust gases, and an exhaust guide arranged to guide exhaust gases from at least one of the at least one combustor to the expander, wherein the exhaust guide is at least partly integrated with the air guide.
