Temperature distribution and thermal correlation of piston rings and piston in high speed diesel engines under actual operating conditions, in spite of their importance, have not been clarified due to the difficulties involved in the measurement. Authors overcame the difficulties and the temperatures were measured directly and precisely by means of thermocouples. As the result, concerning the heat flow pattern and the flow rate, interesting differences among the top, the second and the oil rings, and also between the plain and the taper faced ring were revealed. In addition, the amount of heat transferred to the piston, and the parcentage of each heat released from the piston to other parts were determined.
