Abstract
In a fuel supply system, pressurized fuel is supplied to a delivery pipe from a fuel tank and distributed to fuel injection valves. The delivery pipe includes a main pipe in which upper and lower chambers are defined by a partition wall. One of the fuel injection valves is capable of receiving fuel from both the upper and lower chambers via a particular passage, while the other fuel injection valves are arranged to receive the fuel only from the lower chamber. Bubbles are supplied only to that one fuel injection valve and discharged therethrough. Accordingly, the other fuel injection valves can achieve the normal fuel injection even when the bubbles are present in the delivery pipe. It may be arranged that the partition wall may be omitted. It may further be arranged that the fuel supplied to the delivery pipe is prohibited from returning to the fuel tank and thus is all supplied to an engine via the fuel injection valves.
