Abstract
This internal combustion engine system includes an internal combustion engine, an intake line, an exhaust line, a turbocharger, and an EGR assembly for recirculating a part of the exhaust gases. The EGR assembly has an EGR assembly inlet to collect the part of the exhaust gases, an EGR assembly outlet to allow the part of the exhaust gases towards the compressor. A particulate filter unit is also provided. In the exhaust line, a converter unit decreases nitrogen oxides. The particulate filter unit includes a first particulate filter component, in the exhaust line downstream of converter unit, which defines a first flow path; a second particulate filter component, in the EGR assembly, which defines a second flow path. The first and second particulate filter component are thermally connected, and the first and the second flow paths are separate.
