SPEED CONTROL OF ELECTRONICALLY
CONTROLLED ENGINES - G30, G40SIIIA 4TNV98-Z
4TNV98T-Z
The electronically controlled engines have no governor
lever. For these engines, the position signal of the throttle
lever or accelerator pedal of the driven machine is
converted into an electric signal by the accelerator
sensor, which is then delivered to the rack actuator of the
Eco-govemor through the E-ECU, allowing the engine
speed to be controlled.
