PURPOSE:To enable steam to be smoothly derived from a water jacket, by mounting a steam manifold to independently communicate its respective inlet port in each cylinder to the upper position of its water jacket and guiding the inlet port to an outlet port through a steam collector, in the case of an engine of boiling-cooling type. CONSTITUTION:A steam manifold 30 is mounted to the side end face of a cylinder head 11 through a mounting flange 31, and a respective inlet port 32 provided in each cylinder is independently communicated to a communication port part 17A in the upper position of an outer wall 16 of a main combustion chamber 15 and in a gas-phase refrigerant space in the upper of a water jacket 17 of the cylinder head 11. Then the inlet port 32, having a smooth curved wall, is communicated to a steam collector 33 in the upper position. Further an outlet port 35 is provided in an upper part in the vicinity of an almost central upper end in a longitudinal direction of the steam collector 33. |
