PROBLEM TO BE SOLVED: To provide an injection system for optimally working in a direction injection type internal combustion engine at a low cost. SOLUTION: In this injection system for injecting fuel to a fuel chamber of the internal combustion engine provided with a high-pressure collector chamber 5, pressure is applied to the high-pressure scavenger chamber 5 through a high-pressure pump 3, and the fuel under the high pressure is supplied to a plurality of injectors 6 and 21 through the high-pressure collector chamber 5, and a nozzle needle 22 for closing or opening an injection nozzle 23 is housed in each injector. A first selector valve 7 is housed in a high-pressure conduit 12 provided in the rear of the high-pressure scavenger chamber 5 and connected to the injectors 6 and 21, and inhibition control conduit 25 and 31 can be controlled for opening through other flow through valve 26 positioned near the nozzle housed in the inhibition control pipelines.
