Industry’s first in-cylinder volume production combustion sensor that provides combustion and emissions parameters to the ECU, in real time, thus helping companies to improve the efficiency and reduce emission of IC engines. The technology involves an advanced in-cylinder combustion sensor complemented with our proprietary advanced algorithms, which has the potential to replace pressure sensors, oxygen sensors and knock sensors. This can be achieved without the need for drilling another hole in the cylinder head by adapting the fuel injector or spark plug or glow plug as the sensor.
