ABSTRACT:
A sensing device adapted for attachment to a vehicle engine and responsive to the vacuum created in the intake manifold for transmitting a tactile sensation to the driver to indicate when the vehicle is being driven in an uneconomical manner. The sensing device includes a sensor which is responsive to the vacuum in the intake manifold and, when the vacuum falls below a preselected minimum, causes actuation of a vibrator associated with the throttle linkage. The vibration is transmitted through the throttle linkage to the accelerator pedal, which vibration is felt by the driver. The vibration is terminated when the vacuum in the intake manifold exceeds the preselected minimum, under which condition more economical usage of fuel is achieved.
