Advancing the valve timing of the engine improves its combustion stroke and therefore, its generated power. To guide you on this is the Eagle Vision knock sensor. This component is a type of electronic control unit that takes action on your fuel-air pre-detonation by producing voltage when it's disturbed. The particular current it generates is followed by the engine computer. Right at the first sign of damage, this particular computer triggers the Diagnostic Trouble Code (DTC) or in VVT vehicles, quickly retards the pre-set Variable Valve Timing (VVT) of your automobile.
The Eagle Vision knock sensor will detect pinging or knocking, which signals that you've reached the boundary in advancing your engine's valves. Pinging is actually the noise that the pressure waves in your combustion chamber creates when it collides onto the cylinder walls or the piston of your own engine. It typically develops when the valve timing is advanced past the boundary. A good knock sensor easily detects this occurrence because it's created from Piezoelectric components or crystals which reacts to the impacts by generating electrical current.
When the Eagle Vision knock sensor is badly built or perhaps currently broken, the engine is at risk. Don't allow this to take place; look for a efficient replacement made by number one makes including Beck Arnley, Replacement, and Delphi at Parts Train!
