As for as the past investigations on the heat flow from the piston are concerned, there have been few reports on the gasoline engine. So, in this report, the following are described : (1) The measurement of the temperature distributions of the pistons, piston rings, cylinder wall and gas in the crank case. (2) The measurements of the rates of heat flow from the each part of a piston at each speed of 1500,2500 and 3500rpm, and their comparison with Ibrahim's calculated results. (3) The comparisons of piston temperatures, using various piston rings. As the result, the following were attained : (1) The rate of heat flow from the piston rings and ring lands to the cylinder wall reach as much as 81% at a speed of 3500rpm under full load. (2) The heat transfer coefficient on the back of the piston is 35〜60 kcal/m^2h℃, (3) and besides the valuable data on the use of piston ring for the cooling of piston have been obtained.
