Abstract
A fuel supply and injection system includes a fuel tank, a single electric pump unit, a plurality of fuel injection valves and a piping arrangement. The pump unit is provided in the fuel tank and includes an inlet for taking the fuel in the fuel tank and an outlet for discharging the fuel. The injection valves are secured to an engine main body. Each fuel injection valve includes a nozzle, which is disposed in a corresponding one of combustion chambers and injects the fuel supplied from the pump unit directly into the corresponding one of the combustion chambers. The piping arrangement connects between the electric pump unit and each fuel injection valve. The pump unit is the only pump for supplying the fuel to the fuel injection valves.
