Piston Temperature Measuring Technology Using Electromagnetic Induction

Authors have developed an apparatus which measures the piston temperature using electromagnetic induction. The characteristics of this apparatus are as follows;

1. 1
   Applicable to 6 points per cylinder and all cylinders
2. 2
   Capable of measuring while the engine is running from start to 6000r/min full-load operation
3. 3
   Wide measuring range; from -30 to 400 °C
4. 4
   High accuracy; ±2.5 °C
5. 5
   Quick and easy setup
6. 6
   High durability

This technology contributes to realizing the best balance of piston reliability and matching of combustion conditions. In this report, authors analyzed its influences upon piston temperature when the ignition timing,the oil/water temperature or the oil flow from piston jet were changed, respectively.
