Fuel delivery apparatus in V-type engine

An apparatus for delivering fuel to a V-type engine having a first bank and a second bank, the apparatus comprising:

• a first delivery pipe associated with the first bank;
• a second delivery pipe associated with the second bank;
• a fuel pipe having a supply pipe connected with a fuel tank and a communicating pipe connected with an upstream end of the second delivery pipe;
• a first dampener connected with an upstream end of the first delivery pipe, a downstream end of the supply pipe and an upstream end of the communicating pipe, the first dampener having a relief chamber for damping pressure fluctuation of the fuel, a first passage for introducing some of the fuel supplied from the supply pipe to the first delivery pipe via the relief chamber and a second passage for directly introducing some to the fuel supplied from the supply pipe to the communicating pipe, wherein the first dampener damps pressure fluctuation of the fuel flowing in the first passage;
• a plurality of injectors provided with the first and second delivery pipes, the injectors injecting the fuel from the first and second delivery pipes to cylinders of the engine, respectively;
• a pump located in the fuel tank to supply fuel from the fuel tank to the supply pipe;
• and
• a pressure regulator located in the fuel tank, the pressure regulator controlling the amount of fuel returning from the supply pipe to the fuel tank in accordance with the fuel pressure in the supply pipe to keep the fuel pressure in the fuel pipe and the delivery pipes at a predetermined level without returning the fuel from the delivery pipes to the fuel tank.
