摘要：Dual-fuel injector 14 suitable for a dual-fuel injection equipment (12, figure 1) ofan internal combustion engine (10, figure 1), internally accommodates a first circuit forconveying a first fuel F1 from a first inlet 16 to a first set of injection holes 44 provided ina nozzle tip 22 and, a second circuit for conveying a second fuel F2 from a second inlet 18to a second set of injection holes 46 provided in the nozzle tip. The dual-fuel injectorfurther comprises a first control-valve 36 arranged to control the pressure of the firstfuel in a first control chamber 58 by movement of a first valve member 50 to control theinjection of the first fuel via the first set of injection holes. A second control-valve 34 isarranged to control the pressure of the first fuel in a second control chamber 66 bymovement of a second valve member 52 to control the injection of the second fuel viathe second set of injection holes. Preferably the first fuel is diesel and the second fuel iscompressed natural gas (CNG). Dual-fuel injection equipment comprising such an injectoris also claimed.
