Beschreibung
Zusammenfassung:	A dual-injector fuel injection engine has intake ports (11) each extending at cylinder head (6) obliquely upward from a combustion chamber (16); an intake manifold (21) connected at its downstream side end section to the intake ports (11); an in-cylinder injector (15) for each of the cylinders, injecting fuel directly into the combustion chamber (16); and an intake pipe injector (56) for each cylinder, injecting fuel into the intake port (11). The in-cylinder injector (15) is attached to the cylinder head (6) and is positioned on the lower side of the intake port (11) when viewed from the direction of the axis of a crankshaft (27). The intake pipe injector (56) and a low-pressure delivery pipe (57) for supplying fuel to all the intake pipe injectors (56) are supported at the intake manifold (21), and are positioned, when viewed from the direction of the axis of the crankshaft (27), on the upper side of the intake port (11) so as to be close to the intake port (11).
