Beschreibung
Zusammenfassung:	There is provided a water cooled engine including a cylinder head with minimized thermal strain.A head water jacket 20 includes an inter-exhaust-port-wall water channel 29 between a first exhaust entrance port wall 3d and a second exhaust entrance port wall 3e. A cylinder head 6 includes a cooling water injection passage 27 provided at a bottom wall 6c of the cylinder head 6. The cooling water injection passage 27 is positioned on the exhaust end 6a side, and includes a passage entrance 27a provided on the exhaust end 6a side, and a passage exit 27b directed toward the inter-exhaust-port-wall water channel 29. An exhaust port wall includes a heat dissipation fin 28 extending from a first exhaust entrance port wall 3d toward an exhaust end 6a. The space between the heat dissipation fin 28 and a second exhaust entrance port wall 3e forms a water channel entrance of the inter-exhaust-port-wall water channel 29.
