Menetelmä ja laite ahdetun polttomoottorin suurpainepuoleista pakokaasun kierrätystä varten

摘要

Compressed and cooled charging air (18) is fed into the engine (1) and the exhaust gas (6) from the engine is divided into several flows. A first exhaust gas flow (19) is relaxed in the exhaust gas turbine (11) and used to drive the compressor (3) of the exhaust gas turbo-charger (2). A second exhaust gas flow (20) is firstly cooled, then compressed and finally recirculated, i.e. fed into the engine. A third exhaust gas flow (20) from the engine is relaxed separately from the first exhaust gas flow and the power is used for compression of the second exhaust flow.
