A fuel injection system is described for use with an internal combustion engine have cylinders, comprising: fuel injections valves mounted, respectively, in the cylinders; fuel pressurizing means; fuel passages each connecting a corresponding one of the fuel pressurizing means with a corresponding one of the fuel injection valves; delivery valves arrange, respectively, across the fuel passages; a communication passage connecting at both ends thereof a first one of the fuel passages corresponding to one of the cylinders which is to be fired earlier, to a second one of the fuel passages corresponding to another one of the cylinders which is to be fired later. Each is at a location between one of the fuel injection valves and a corresponding one of the delivery valves associated with the first and second fuel passages; the delivery valves each having an outlet port, the communication passage being connected at both ends thereof to the first and second fuel passages each at a location in the vicinity of the outlet port of a corresponding one of the delivery valves; and a selector valve arranged between the first fuel passage and the communication passage for selectively connecting one of the delivery valves across the first one fuel passage with the communication passage in a predetermined low load and low speed region of the engine.
