ABSTRACT:
A throttle motion indicator device for an internal combustion engine of a vehicle having an induction system including a movable throttle for controlling flow through an induction passage and, an operator actuated accelerator pedal linkage, including a throttle rod, operatively connected to the throttle for controlling movement thereof, the indicator device including a spring positioned roller carried by the throttle rod in position to engage a detent means suitably positioned in the path of the roller as carried by the throttle rod to indicate to the operator a throttle position for improved fuel economy. With this device, the driver depresses the accelerator pedal until he feels a slight stiffening in the throttle movements which alerts him that he has reached a predetermined limit in acceleration rate to obtain good fuel economy. In an alternate embodiment, the detent means carries two detents to provide a signal to the operator of a range of throttle positions within an optimum acceleration range.
