Abstract:
A valve timing system for use within an internal combustion engine of the type including a plurality of cylinders each having at least one valve, said valve timing system comprising:at least one actuator which selectively actuates said at least one valve; a sensor which is effective to detect knocking within a unique one of said plurality of cylinders, and to generate a first signal in response to said detection; and a controller which is communicatively coupled to said at least one actuator and to said sensor, said controller being effective to receive said signal and to selectively communicate a second signal to said at least one actuator corresponding to said knocking cylinder, said second signal having a value based upon said first signal and being effective to cause said at least one actuator to alter the actuation of said at least one valve while said engine is operating, thereby dynamically suppressing said knocking within said cylinder.
