Zusammenfassung:PCT No. PCT/US83/00028 Sec. 371 Date Jan. 10, 1983 Sec. 102(e) Date Jan. 10, 1983 PCT Filed Jan. 10, 1983 PCT Pub. No. WO84/02746 PCT Pub. Date Jul. 19, 1984.A vacuum-mechanical system for controlling emissions from a diesel engine by controlling exhaust gas recirculation (EGR) levels and modulating the fuel injection pump timing to coordinate the two; the system including a three-dimensional cam responsive to changes in engine speed and load and fuel delivery to vary the angular position of the EGR valve and simultaneously modulate the injection timing.
