ABSTRACT:
Carburetor power valve control apparatus for an internal combustion engine. The control apparatus includes a vacuum motor and temperature sensitive power means. The power means opens and closes a vacuum bleed port in communication with the vacuum motor so that under cold operating conditions the power valve opens at a greater actual intake manifold vacuum than under warm operating temperatures. This results in earlier power valve opening at cold engine temperatures which improves drivability and allows balancing of all carburetor fuel systems to achieve improved fuel economy and reduced engine emissions.
