ABSTRACT:
FIGS. 1a, 1b, 1c, 1d, and 1e collectively schematically illustrate a fuel injection control system for an internal combustion engine having a fuel pump 38 that has a fuel flow output that varies as a direct function of engine speed, an air/fuel ratio controller 100 that has a mechanical linkage that varies the output of pump 38 as a function of changes in engine intake manifold vacuum acting on an aneroid 122 to maintain a constant air/fuel ratio to the engine mixture charge, and a linkage type regulator with five vacuum controlled motors 156, 170, 178, 186 and 190, that modify the position of the regulator 100 in a step-wise progressive and sequential manner to establish exhaust gas recirculation (EGR) and to change fuel flow to compensate for the change in oxygen concentration in the mixture charge due to EGR flow and other engine operating conditions as well as engine operating temperature changes.
