Development of an on-board visual display for early knock detection in SI engine

The main purpose of this project is to develop an on-board visual display for early knock detection in SI car engines. The system consists of a low-cost piezoelectric accelerometer and two signal processing boards with wireless data transmission capability. One board is placed on the engine side and...
