Abstract
Even in the case where a crankshaft extends in a substantially vertical direction, it is possible to reduce a situation that sprays of fuel injected from injectors may adhere to inner wall surfaces of intake passages, and it is possible to make the fuel supply to combustion chambers stable. Provided is a vertical engine including: a pair of intake passages (and) which are arranged in an up and down direction with the interposition of a central axis of a cylinder () therebetween; a pair of intake valves (LandL) which open and close the pair of intake passages; and fuel injectors (LandL) which inject fuel to the pair of intake passages; wherein: the fuel injectors are arranged so that fuel injection directions by the fuel injectors can go not toward valve stems () of the intake valves provided in the upper and lower intake passages respectively but toward the backs of valve heads of the intake valves on a central axis (C) side of the cylinder and the fuel injectors are disposed so that a central axis (FC) of injection of the fuel injector into the lower intake passage can be closer to the central axis side of the cylinder than a central axis (CF) of injection of the fuel injector into the upper intake passage.
