FUEL INJECTION SYSTEM FOR AN INTERNAL COMBUSTION ENGINE AND METHOD OF OPERATING A FUEL INJECTION SYSTEM IN AN INTERNAL COMBUSTION ENGINE

摘要

The invention relates to a fuel injection system for an internal combustion piston engine (100) comprising a fuel source (134), which is arranged in connection with a fuel admission port (121) which is arranged to deliver the fuel to be combusted in the internal combustion piston engine in intermittent manner, which fuel injection system comprises at least one fluid flow control device arranged to control the flow of fuel into the fuel admission port (121). The at least one fluid flow control device (22) comprises at least two parallel valve units (22.1... 22.N) each having two operational positions.
