Fuel supply device for direct injection engine

A fuel supply device for supplying fuel to fuel injectors installed to a direct injection internal combustion engine so as to spray fuel directly into cylinders of said direct injection internal combustion engine arranged in a straight row in a transverse direction of a vehicle body, said fuel supply device comprising:

• at least two camshafts extending in parallel to each other in said transverse direction of said vehicle body over said direct injection internal combustion engine;
• a high-pressure fuel pump for pressurizing said fuel and forcing said pressurized fuel into said fuel injectors, said high-pressure fuel pump being located adjacent to part of said direct injection internal combustion engine at a front side of said direct injection internal combustion engine in a lengthwise direction of said vehicle body so as to be driven by one of said two camshafts which is located on said part of said direct injection internal combustion engine in said position and is inclined rearward in said lengthwise direction;
• a fuel supply pipe connected to a fuel discharge port located at a bottom of said high-pressure fuel pump;
• and
• a fuel return pipe connected to a fuel return port located at an upper back of said high-pressure fuel pump, wherein said high-pressure fuel pump supplies said pressurized fuel to said fuel injectors through said pressurized fuel supply pipe and receives low pressure fuel returning from said fuel injectors through said fuel return pipe.

A fuel supply device for supplying fuel to fuel injectors operative to spray fuel directly into cylinders of a direct injection internal combustion engine arranged in a straight row in a transverse direction of a vehicle body, said fuel supply device comprising:

• a first camshaft extending in said transverse direction of said vehicle body over said direct injection internal combustion engine;
• a second camshaft extending in parallel to said first camshaft and located on a front side of said first camshaft over said direct injection internal combustion engine;
• a high-pressure fuel pump for pressurizing said fuel and forcing said pressurized fuel into said fuel injectors, said high-pressure fuel pump being located adjacent to part of said direct injection internal combustion engine at a rear side of said direct injection internal combustion engine in a lengthwise direction of said vehicle body so as to be driven by said second camshaft;
• a pump drive cam located below said high-pressure fuel pump so as to be driven by said first camshaft to drive said high-pressure fuel pump,
• wherein said high-pressure fuel pump is inclined forward in a lengthwise direction of said vehicle body so as to have a top thereof in front of a bottom thereof in said lengthwise direction.
