Connector View & Information: - Sensor Specification and Sensor standalone diagnosis:- The knock Sensor provides input to ECU based on the vibration generated by 'knocking', which will enable ECU to limit ignition timing (Advance) for optimum efficiency. The knocking is the vibration generated due to uncontrolled combustion, due to which a charge transfer occurs in the Sensor and as a result voltage is generated which is transmitted to ECU. The knock Sensor is mounted on the cylinder block. Application of Knock Sensors :- A piezo sensitive knock Sensor with linear characteristic is mounted on the engine block. It transforms the structure borne vibrations into electrical signals which can be evaluated by the engine’s ECU. The knock Sensor signal is evaluated according to intensity and spectral information of knocking and non-knocking combustions. As a consequence the ignition parameter Knock Sensor for Altroz NGTC
