Apparatus for controlling recirculated exhaust gas quantities in self-igniting internal combustion engines

Patent ·
OSTI ID:6455049
An apparatus is described for controlling recirculated exhaust gas quantities in self-igniting internal combustion engines which have a fuel injection pump. Two parameters, the rpm (preferably via the rpm-dependent suction chamber pressure) and the position of the quantity-adjusting device, are obtained from the fuel injection pump and delivered to a performance-graph memory in which a control value for the recirculated exhaust gas quantity is stored in accordance with these parameters. A recirculated exhaust gas quantity control device is actuated in accordance with the recalled control value.
