Abstract
Fuel supply system comprising at least a fuel source and a high-pressure pump in flow communication therewith for raising the fuel pressure up to an increased pressure, at least two fuel injectors arranged in conjunction with engine cylinders, each of which injectors is in flow communication with the high-pressure pump, and via a pressure accumulator unit. At least one pressure accumulator unit is in connection with both the fuel injector and at least one other pressure accumulator unit for fuel.
