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.

Abstract: A fuel supply device for internal combustion engines wherein the temperature of the fuel fed to an injection pump can be regulated in order to avoid temperature influences on the fuel metering operation. For this purpose, fuel is withdrawn in a controlled quantity via a temperature-controlled valve from the intake chamber of the injection pump, where the fuel is under the feed pressure of a fuel feed pump and the withdrawn fuel is fed, either by way of a heat exhchanger or directly back to the intake side of the fuel feed pump. In this arrangement, the inherent fuel heating process taking place in the fuel injection pump is exploited to regulate the temperature of the fuel fed to the fuel feed pump.

Abstract: A fuel injection system utilized with an engine having pre-combustion chambers, main combustion chambers, a fuel metering and quantity distribution valve, a suction tube and an air measuring member are described in further detail hereinafter. The fuel metering and quantity distribution valve has a control slide member which is controlled in its displacement by the air measuring member. The control slide member controls the fuel metered to the engine. The fuel metering and quantity distribution valve has a first differential pressure valve associated therewith which maintains the pressure difference between the fuel pressure prevailing upstream and downstream of the fuel metering location constant during injection. Structure is provided to change the pressure difference in dependence on engine parameters.
