Abstract (en)
[origin: EP0473931A2] Additional combustion gas and/or returned exhaust gas is fed by way of an additional air duct/turbulence duct to an inlet duct of an internal combustion engine. In the additional air duct a control element, which primarily influences the quantity of additional combustion gas, is provided upstream of the outlet of the exhaust gas return line. At the same time however it is also possible with this control element to influence the quantity of returned exhaust gas as opposed to the quantity of combustion gas fed in. The control element is coupled to a throttle element provided in the inlet duct of the internal combustion engine. <IMAGE>
