Fitment: For Espace IV JK01 19 20 22 30 Key benefits Accurate knock detection The sensor monitors engine vibrations to detect abnormal combustion, helping protect the engine from longterm damage. By identifying irregular firing patterns, it supports realtime adjustment for improved performance and efficiency. Smooth ignition timing With precise input to the control unit, this engine knock 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 detonation sensor helps prevent misfires and potential engine wear. It plays a critical role in maintaining fuel efficiency and minimising the risk of overheating or power loss during operation. How it works Function Monitors engine vibrations to identify abnormal combustion and detonation, providing data to the engine control unit for timely timing adjustments. Performance impact Supports realtime adjustments to improve efficiency and overall engine performance, while reducing the risk of engine wear from detonation. Practical applications Daily commuting Works under varying engine loads to maintain ignition timing and protect the engine during regular driving. Towing or heavy load conditions Helps sustain stable ignition timing and performance when additional load is placed on the engine. Driving with variable fuel quality or tuning Detects detonation early to maintain efficiency and prevent engine damage across changing conditions.
