ABSTRACT:
When the engine runs on all cylinders thereof, a diaphragm device for a hydraulic pressure regulating valve will operate in response to a pressure difference between the atmospheric pressure and intake vacuum within an intake manifold of the engine. A control system includes a solenoid valve which, when the engine runs on selected cylinders of all, will apply vacuum within a source of a predetermined vacuum to the diaphragm device. According to one preferred embodiment, the diaphragm device has a single chamber and the solenoid valve is adapted to selectively apply the induction vacuum and the predetermined vacuum to the single chamber. According to another preferred embodiment, the diaphragm device has a first chamber in communication with the intake manifold and a second chamber and the solenoid valve is adapted to selectively apply the atmospheric pressure and the predetermined vacuum to the second chamber.
