Patent ID: 7913667

Claim:
A fuel supply apparatus for a vehicle, comprising: a fuel tank for storing fuel; a first fuel supply system including a first fuel injection mechanism for injecting fuel into an internal combustion engine; a second fuel pipe supply system including a second fuel injection mechanism different from said first fuel injection mechanism for injecting fuel into said internal combustion engine; a first fuel pipe for guiding said fuel from said fuel tank to said first fuel supply system; and a second fuel pipe for guiding said fuel from said fuel tank to said second fuel supply system; wherein a branch point between said first and second fuel pipes is arranged such that a fuel pipe length between said branch point and said fuel tank is shorter than a fuel pipe length between said branch point and each of said first and second fuel supply systems to ensure pressure variation suppression, said first fuel supply system includes a high-pressure fuel pump for pressurizing the fuel guided by said first fuel pipe and discharging resultant fuel, and is configured to control a pressure of the fuel injected from said first fuel injection mechanism to a prescribed pressure, and said second fuel supply system is configured to set a pressure of the fuel injected from said second fuel injection mechanism to a pressure lower than said prescribed pressure.
