To help improve the efficiency and reduce emission of internal combustion engine, DEP has developed new capability for real time in-cylinder sensing. An advanced in-cylinder combustion sensor complemented with our proprietary advanced algorithms has the potential to replace pressure sensors, oxygen sensors and knock sensors. The latest technology from DEP enables performing multiple sensing tasks and real time Engine management by provided feedback to the electronic control of engine to achieve goals of future stringent emission norms and fuel economy standards.
Many techniques have been investigated to directly or indirectly monitor the combustion process including:
1. Crank shaft dynamics to detect misfiring, found to fail in multi-cylinder engines and at high engine speeds
2. Optical sensors, found to lack accuracy and durability
3. Techniques based on Neural analysis, found to be limited to certain operating windows, beyond which they are not accurate
4. Pressure transducers
5. Advanced sensors.
