A combustion pressure control system of an internal combustion engine provided with a fluid sealing member 63 which is filled with a compressible fluid inside and which is arranged at a piston 3 and a channel 75 of a coolant for adjusting a temperature of the compressible fluid at the inside of the fluid sealing member 63. When a pressure of a combustion chamber reaches a predetermined pressure, the fluid sealing member 63 contracts, whereby the volume of the combustion chamber increases. The combustion pressure control system is formed to run coolant through the channel 75 to adjust the temperature of the compressible fluid and adjust the pressure inside of the fluid spring. |
