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.
Claims9
Device for exhaust gas recycling in internal combustion engines equipped with a fuel injection system, including an injection pump, and having a throttle valve to control the recycled stream of exhaust gas arranged in the intake manifold, further wherein the throttle valve for an exhaust gas return line terminates in said intake manifold and is directly connected with an adjusting lever of said injection pump.
