In multi-cylinder engine in which an intake valve and a first spark plug arranged side by side along an axis of a camshaft and an exhaust valve and a second spark plug arranged side by side along the axis of the camshaft are disposed in a cylinder head for every combustion chamber, the position of a central portion of an upstream end of an intake port provided in the cylinder head with the intake valve interposed between the intake port and each of the combustion chambers and the position of a central portion of a downstream end of an exhaust port provided in the cylinder head with the exhaust valve interposed between the exhaust port and each of the combustion chambers are set to correspond with each other in the direction along the axis of the camshaft. Thus, the length of the cylinder head is reduced.
A multi-cylinder engine in which an intake valve and a first spark plug arranged side by side along an axis of a camshaft and an exhaust valve and a second spark plug arranged side by side along the axis of said camshaft are disposed in a cylinder head for every combustion chamber, wherein the position of a central portion of an upstream end of an intake port provided in the cylinder head with said intake valve interposed between said intake port and each of the combustion chambers and the position of a central portion of a downstream end of an exhaust port provided in the cylinder head with said exhaust valve interposed between said exhaust port and each of the combustion chambers are set to correspond with each other in the direction along the axis of said camshaft.
