Abstract
A dual-injector fuel injection engine includes a cylinder block, a cylinder head, an intake port, an intake manifold, a surge tank, an in-cylinder injector, an intake pipe injector, and first and second delivery pipes. The in-cylinder injector is positioned below the intake port, when seen from an axial direction of a crank shaft, and attached to the cylinder head. The intake pipe injector and the second delivery pipe are supported above the intake port, when seen from the axial direction of the crank shaft, by the intake manifold to be close to the intake port.
