초록

In a fuel supply system employing a returnless fuel pipe arrangement, a relief valve is provided at a discharge side of a fuel pump. The relief valve is opened when fuel pressure in the fuel pipe arrangement becomes no less than a system protective pressure, so as to relieve the fuel pressure to protect the system. The relief valve is also arranged to be open when the fuel pressure in the fuel pipe arrangement becomes higher than a target fuel pressure by a predetermined value or when the fuel cut is performed. Thus, the fuel pressure in the fuel pipe ar...
