ABSTRACT:
A high-pressure fuel supply system is suitable for an internal combustion engine having an in-cylinder injector for injecting a fuel into a cylinder. The high-pressure fuel supply system includes a high-pressure fuel pump driven by an engine, a high-pressure delivery pipe supplying the fuel from the high-pressure fuel pump to the in-cylinder injector, and an actuation valve provided with a leakage function provided between the high-pressure fuel pump and the high-pressure delivery pipe. An amount of leakage in the actuation valve provided with the leakage function is set to an amount not smaller than a discharge amount of the high-pressure fuel pump.
