Abstract

The present invention relates to an internal combustion engine and operating method. The internal combustion engine includes a fresh air system for the supplying of fresh air to at least one combustion chamber; an exhaust gas system for the carrying away of exhaust gas from the at least one combustion chamber; an exhaust gas recycling system for the recycling the exhaust gas from the exhaust gas system into the fresh air system; and at least one additional valve, configured in the fresh air system upstream of at least one inlet valve associated with the at least one combustion chambers. A control device is configured to actuate at least one additional valve such that at least one of a particle content in the exhaust gas and a fuel consumption of the internal combustion engine are at least one of optimum and optimal comprise for at least one environmental parameter.
