摘要:
A fuel adding nozzle 17 is embedded including its front end member 17c into an internal wall of an exhaust port 40a formed within a cylinder head 100a. An injection passageway 101c guides, into the exhaust port 40a, the fuel jetted out of the front end member 17c of the fuel adding nozzle 17. A wall 102 provided between the front end member 17c and the exhaust port 40a decreases a heat receiving quantity of the fuel adding nozzle 17. A water jacket 110 is proximal to an outer edge of a nozzle seat 103, thereby efficiently transferring the heat contained in a gasket 17d to cooling water in the water jacket 110.
