ABSTRACT:
An internal combustion engine operating aid which produces a signal to the engine operator when the engine throttle is depressed or released so rapidly as to reduce engine operating economy. Such a signal is produced responsive to the actuation of a diaphram or piston contained within a chamber. Each side of the diaphram or piston is connected to the engine inlet manifold, however the connecting path to one side contains a restriction orifice. Thus the pressure on the side of the diaphram or piston having no restriction orfice changes immediately upon a change of pressure in the inlet manifold, such an inlet manifold pressure change being characteristic of uneconomical rapid acceleration or deceleration, while the pressure on that side having a restriction orifice in the connective path between it and the inlet manifold changes more slowly due to the restriction, this pressure differential producing movement of the diaphram or piston and a signal to the engine operator responsive to such movement.
