Fuel supply apparatus for engine

摘要

A fuel supply apparatus for an engine, includes a first cylinder group, a second cylinder group, first fuel injection valves, second fuel injection valves, a fuel supply pipe, a branch portion, a first connecting pipe, a second connecting pipe, a first delivery pipe, and a second delivery pipe. The branch portion has an inflow direction along which fuel is to flow from the fuel supply pipe into the branch portion. The branch portion has a first outflow direction along which fuel is to flow from the branch portion into the first connecting pipe. The branch portion has a second outflow direction along which fuel is to flow from the branch portion into the second connecting pipe. All of the inflow direction, the first outflow direction, and the second outflow direction are provided not to lie in a same straight line.

1. A fuel supply apparatus for an engine, comprising:
a first cylinder group including a plurality of cylinders; a second cylinder group including a plurality of cylinders; first fuel injection valves to inject fuel to the cylinders of the first cylinder group; second fuel injection valves to inject fuel to the cylinders of the second cylinder group; a fuel supply pipe connected to a fuel supply source; a branch portion connected to the fuel supply pipe and having an inflow direction along which fuel is to flow from the fuel supply pipe into the branch portion, the branch portion having first, second, and third connecting ports formed as channels that extend orthogonally to each other; a first connecting pipe extending in a first axial direction and connected to the branch portion, the branch portion having a first outflow direction along which fuel is to flow from the branch portion into the first connecting pipe; a second connecting pipe extending in a second axial direction and connected to the branch portion, the branch portion having a second outflow direction along which fuel is to flow from the branch portion into the second connecting pipe, all of the inflow direction, the first outflow direction, and the second outflow direction being provided not to lie in a same straight line, the first axial direction of the first connecting pipe intersects the axial second direction of the second connecting pipe at the branch portion; a first delivery pipe connected to the first connecting pipe to deliver fuel via the first fuel injection valves to the cylinders of the first cylinder group; and a second delivery pipe connected to the second connecting pipe to deliver fuel via the second fuel injection valves to the cylinders of the second cylinder group.
