Abstract
A valve timing system is provided for dynamically suppressing cylinder knock within an internal combustion engine. The engine is of the type including several cylinders , each having intake and exhaust valves . Valve timing system includes a controller , sensors , and actuators which selectively actuate valves in response to signals received from controller . Controller identifies knocking within one or more of cylinder(s) , and provides a modified control signal to the valve actuators which are associated with the identified cylinder(s). The modified control signal alters the duration in which the valves remain open, thereby suppressing knocking within the cylinder(s) without adversely effecting the vehicle's fuel economy or emissions.
