are communicated so that pressure can be input through the inlet relief valve 3, and communicated so that pressure can be released through the outlet check valve 4, so that the combustion chamber pressure is transferred to the inlet relief valve 3 while the pressure in the combustion chamber 1 is rising. When the valve is opened, the pressure is released to the peak pressure reduction chamber 2, and when the combustion chamber 1 is decreasing, the pressure in the peak pressure reduction chamber 2 is released to the combustion chamber when the outlet check valve 4 is opened. The valve-opening pressure L of the inlet relief valve 3 is the combustion chamber peak pressure A combustion chamber device for an engine, characterized in that the combustion chamber device is set to a value smaller than a maximum inter-chamber pressure difference Z1 with respect to a residual pressure Y, and larger than a maximum inter-chamber pressure difference Z2 during light load operation.
