Compatibility: Palio Siena Strada Doblo 2001 - Accurate knock detection: This knock sensor monitors engine vibrations to detect abnormal combustion, helping protect the engine from long term damage. By identifying irregular firing patterns, it supports real time adjustment for improved performance and efficiency. - Smooth ignition timing: With precise input to the engine control unit, this sensor helps optimise ignition timing based on engine load. It contributes to stable acceleration and smoother driving by ensuring combustion happens at the ideal moment. - Prevents costly engine damage: Early detection of detonation through this sensor helps prevent misfires and engine wear. It plays a critical role in maintaining fuel efficiency and minimising the risk of overheating or power loss during operation. Use cases - Daily urban driving with varying fuel quality, where knock risk can occur, the sensor helps protect the engine and improve efficiency. - Highway driving and rapid acceleration, where timing adjustments improve response and smoothness. - Driving with heavy loads or on inclines, where ignition timing optimization supports consistent power and reduces knock risk.
