ICOS Temperature System
LaVision's innovative Internal Combustion Optical Sensor (ICOS) Temperature measures crank angle resolved temperatures directly in the combustion chamber of internal combustion engines under real fuel conditions.Firing (spark plug) and non-firing probes are available. The spark plug probe has M12 or M14 threads and do not need any further engine modification. A non firing M5 sensor can be used for standard bores of the engine.
Applications
- determination of absolute in-cylinder temperature
- visualization of compression stroke temperature rise
- detection of abnormal engine performance
- effects of different EGR rates and valve timings on in-cylinder temperatures
