Abstract

An injector system which is in particular used as an injector block for fuel injection systems of mixture-compressing, spark-ignited internal combustion engines includes a fuel distribution rail, a counter bracket, a first injector, and at least one second injector. Here, the counter bracket has a first connecting piece and a second connecting piece. The first injector is joined to the counter bracket on an input side of the first connecting piece with the aid of an elastic sealing ring. The second injector is joined to the counter bracket on an input side of the second connecting piece with the aid of an elastic sealing ring. In this case, the counter bracket is connected to the fuel distribution rail. The fuel distribution rail is used for distributing compressed natural gas to the injectors. The injector system has a compact design.
