Internal combustion engine having an exhaust-gas and charge-air guidance arrangement

摘要

An internal combustion engine has first and second non-deactivatable cylinder banks. Each cylinder bank is assigned exhaust lines which extend from exhaust manifolds. First and second exhaust-gas turbocharger in the exhaust line are assigned to the first and second cylinders, respectively. A first catalytic converter in the first exhaust line contains the first exhaust-gas turbocharger, and is arranged downstream of the first exhaust-gas turbocharger as viewed in the flow direction of the exhaust gas of the first cylinder bank. A second catalytic converter in the second exhaust line contains the second exhaust-gas turbocharger, and is arranged downstream of the second exhaust-gas turbocharger as viewed in the flow direction of the exhaust gas of the second cylinder bank. A flow transfer line is arranged between the first and the second exhaust line, and a first control element, by an exhaust-gas mass flow passing through the flow transfer line can be regulated.

1. An internal combustion engine comprising:
a first, non-deactivatable cylinder bank; a second, deactivatable cylinder bank; first and second exhaust lines which are assigned to the first and second cylinder banks, respectively, and which extend from exhaust manifolds; a first exhaust-gas turbocharger in the first exhaust line assigned to the first cylinder bank; a second exhaust-gas turbocharger in the second exhaust line assigned to the second cylinder bank; a first catalytic converter in the first exhaust line which contains the first exhaust-gas turbocharger, which first catalytic converter is arranged downstream of the first exhaust-gas turbocharger in the flow direction of the exhaust gas of the first cylinder bank; a second catalytic converter in the second exhaust line which contains the second exhaust-gas turbocharger, which second catalytic converter is arranged downstream of the second exhaust-gas turbocharger in the flow direction of the exhaust gas of the second cylinder bank; a flow transfer line which is arranged between the first and the second exhaust line; and a first valve that is configured to regulate an exhaust-gas mass flow passing through the flow transfer line.
