Abstract
To enable a reduction of the number of fuel pipes and joint parts to facilitate piping work, maintenance and inspection. An engine fuel injection apparatus includes first fuel injection valves provided on an upstream side of an air intake passage of an engine, second fuel injection valves provided on a downstream side of the air intake passage, and a fuel pump for supplying fuel to the first and the second fuel injection valves. The second fuel injection valves are positioned at a level lower than the first fuel injection valves, and the fuel pump is connected to the second fuel injection valves via the first fuel injection valves by fuel feed pipes, so that fuel does not return to a fuel tank of the engine.
