Beschreibung
Zusammenfassung:	Three way valves forming a fuel cut-off valve are arranged across respective injection pipes connected to injection nozzles associated with preselected cylinders of the engine. In a first valve position, the three way valves connect the injection pump body or bodies of the fuel injection pump to the respective injection pipes, and in a second valve position, they connect the injection pump body or bodies to a lower pressure zone in the pump. Preferably, the fuel cut-off valve is pneumatically operated for high speed valve position changing action.
