ABSTRACT:
A mixture-compressing reciprocating-piston internal combustion engine with two separate cylinder rows and a single mixture-producing device, in which one row is supplied with a slightly richer air/fuel mixture from a common mixture-producing device which is then leaned down by the admixture of additional air while the other cylinder row is supplied with an air/fuel mixture which is as accurately as possible stoichiometric; oxygen probes are thereby used upstream of the respective catalysts to control a valve controlling the additional air inlet to the one cylinder row and the fuel supply to the mixture-producing device.
