Abstract
A combustion engine having an exhaust-gas driven turbo compressor is provided with a device for recirculating exhaust gases to the engine, this device being connected to the exhaust system of the engine upstream of the turbo compressor and being provided with a cooling device for the recirculated exhaust gases. The engine is provided with at least two exhaust valves per cylinder and has divided exhaust gas flow, each cylinder being connected by a first exhaust valve to a first exhaust collector, which leads to the turbine of the turbo compressor, and each cylinder being connected by a second exhaust valve to a second exhaust collector, which is connected to the exhaust system of the engine downstream of the turbine. The second exhaust collector forms part of the device for recirculating exhaust gases to the engine and is also connected to the inlet of the engine.
