An internal combustion engine includes an exhaust-gas system with n&#x3e;1 exhaust-gas flow configurations, wherein n is an integer. The exhaust-gas flow configurations are at least partly separated from one another and each of the exhaust-gas flow configurations includes at least one catalytic converter. The internal combustion engine includes a secondary air supply system with at least one secondary air pump and at least one secondary air valve. The at least one secondary air pump is connected, via the at least one secondary air valve, to at most n&#x2212;1 of the exhaust-gas flow configurations upstream of the at least one catalytic converter of the at most n&#x2212;1 of the exhaust-gas flow configurations. The remaining ones of the exhaust-gas flow configurations are separated from the secondary air supply system.
