Abstract
A device for exhaust gas recycling is proposed which controls the amount of recycled exhaust gas in an internal combustion engine equipped with an injection unit so that a certain air factor is attained. The device comprises a closing element for the exhaust gas return conduit, which latter terminates into the intake manifold, this closing element being suitably constituted by a throttle valve and being directly connected to the adjusting lever or control rod of the injection pump. If this connection is established via a resilient linkage between the adjusting lever and the exhaust gas return valve, then the thus-recycled amount of exhaust gas can be dimensioned so that a specific quantity of recycled exhaust gas is associated with a specific angular position of the adjusting lever.
