ABSTRACT:
An internal combustion engine, which outside of the upper load range is operated with a lean mixture, has a device which sets the fuel-air mixture in the combustion chamber into increased motion. This device is activated as soon as a switchover is made to lean-burn operation, and is deactivated when the change is made from lean-burn operation to stoichiometric operation. To ensure that these switchover operations of the device will influence the engine torque as little as possible, the fuel flow is reduced for a specifiable period of time after the device is switched on, and the fuel flow is increased for a specifiable period of time after the device is switched off.
