Knock Sensor
About knock sensors
This sensor uses piezoelectric ceramics to detect engine knocking vibrations and is used in ignition timing control, contributing to improved engine performance, fuel efficiency, and engine protection when using low-octane fuel.
Main Products
ERAS®-KN (Non-resonant knock sensor)
Purpose
A knock sensor is a sensor that detects engine knocking vibrations using piezoelectric ceramics. It is used for ignition timing advance control and contributes to improved engine performance and fuel efficiency.
Features
- The output is flat in the 5-15kHz frequency range, which is the knocking region, making it highly versatile and usable regardless of engine type.
- Vehicles equipped with this system: 4-wheel vehicles, 2-wheel vehicles, construction machinery, stationary gas engines, outboard motors, snowmobiles
- New Technology: Lead-Free Piezoelectric Elements (Piezoelectric Ceramics) We have successfully developed a lead-free piezoelectric element with high output and low temperature dependence, overcoming the challenges to the practical application of lead-free piezoelectric elements.
