Abstract: The invention relates to an exhaust gas recirculation apparatus (5) for an internal combustion engine (1), in particular in a motor vehicle, having an exhaust gas recirculation line (9) which can be connected at the inlet end to an exhaust gas system (4) of the internal combustion engine (1) and at the outlet end to a fresh gas system (3) of the internal combustion engine (1) and having a return valve (12) arranged in the exhaust gas recirculation line (9) for adjusting an exhaust gas recirculation rate by varying the flow-through cross section of the exhaust gas recirculation line (9). To improve the efficacy of the exhaust gas recirculation, the exhaust gas recirculation valve (12) is designed so that it adjusts the respective exhaust gas recirculation rate at least in one operating state of the exhaust gas recirculation apparatus (5), so that it alternately reduces and increases and/or blocks and opens the flow-through cross section of the exhaust gas recirculation line (9) at predetermined or regulated switching points in time.

Abstract: A fuel injection system includes a pressure storage chamber and one injector assigned to each cylinder, which injector can be connected to the pressure storage chamber via a pressure line that includes a metering valve. Using a single 2/2-way valve as a metering valve per cylinder makes for a more-economical manufacture of a fuel system, especially for small engines. The fuel injection is done under pressure control.
