Abstract
A boost regulator for a supercharger is responsive to one or more vehicle operation parameter inputs to determine limits of boost applied to an internal combustion engine. In one configuration, the boost regulator limits the amount of movement of a conventional dashpot boost control valve actuator based on various vehicle and sensor input data. In another configuration, the boost regulator adjusts the amount of boost output during supercharger operation in response to the vehicle and sensor input data.
Claims20
A supercharger boost control assembly comprising:
- a boost regulator configured to control the output of a supercharger, the boost regulator in communication with a boost control valve having a boost valve arm, the boost control valve defining a first stop position and the boost regulator configured to limit the boost control valve to a second stop position that is different from the first stop position;
- and
- a controller having a boost control profile, the controller receiving an at least one vehicle operation input parameter to define the second stop position.
A supercharger boost control assembly comprising:
- a vacuum powered, boost control dashpot coupled to a boost valve arm that communicates with a boost control valve, the boost control valve defining a first stop position;
- and
- a variable position backstop configured to be selectively oriented relative to the boost valve arm to define a second stop position that is different from the first stop position.
A supercharger boost control assembly comprising:
- a boost regulator configured to control the output of a supercharger, the boost regulator in communication with a boost control valve having a boost valve arm, the boost control valve defining a first stop position defining a no boost output condition of the supercharger and the boost regulator configured to selectively move the boost control valve to a second stop position defining one of a partial boost output condition or a full boost output condition of the supercharger;
- and
- a controller having a boost control profile, the controller receiving an at least one vehicle operation input parameter to define the second stop position.
