having fuel injector 116 referring still to fig6 a control signal 48 may be provided to fuel control device 118 which controls fuel flow to injector 116 in the same manner in which control signal 48 is provided to throttle actuator 112 as described above second exemplary engine control system 120 shown in fig6 b may include the same elements as first exemplary engine control system 50 shown in fig6 a however speed sensor 68 and operator control 46 are differently arranged in second exemplary engine control system 120 specifically speed sensor 68 receives a fixed voltage supply for example from a battery and produces measured speed signal 122 measured speed signal 122 is supplied to operator control 46 operator control 46 provides speed control signal 48 to throttle actuator 112 and or fuel control device 118 third exemplary engine control system 130 shown in fig7 may alternatively provide speed control signal 48 and command speed signal 108 separately to an engine control module ecm 124 ecm 124 may sum compare filter or otherwise operate on the signals to provide throttle signal 126 to throttle actuator 112 and fuel control signal 128 to fuel control device 118 advantageously flyweight governor 34 and sensor 68 of engine control systems 50 120 130 provide control signal 48 which may be related to actual and commanded engine speed which may be used to control the intake system of an engine and which may be easily electrically or electronically filtered buffered amplified limited or attenuated to better control the magnitude and oscillation of transient speed adjustments generally associated with known engine control systems which only include mechanical components it is also advantageous in many applications related to.
