A fluid injector for direct injection of compressed natural gas into a combustion chamber of a combustion engine, the fluid injector comprising:
- an injector housing including a fluid path wherein the fluid path extends along a longitudinal direction from an injector inlet to an injector outlet;
- one coil;
- a pole piece;
- a first valve configured to act on the fluid path and comprising a first armature;
- and
- a second valve configured to act on the fluid path and comprising a second armature,
- wherein the first armature and the second armature are arranged proximate to the pole piece on antipodal sides of the pole piece along the longitudinal direction.
A combustion engine, comprising:
- a cylinder having a combustion chamber;
- and
- a fluid injector coupled to the cylinder in a manner capable for direct injection of a fuel fluid into the combustion chamber of the cylinder, the fluid injector comprising:
- an injector housing including a fluid path wherein the fluid path extends along a longitudinal axis of the fluid injector from an injector inlet to an injector outlet;
- a single coil;
- a pole piece;
- a first valve configured to act on the fluid path and comprising a first armature;
- and
- a second valve configured to act on the fluid path and comprising a second armature,
- wherein the first armature and the second armature are arranged proximate to the pole piece on antipodal sides of the pole piece along the longitudinal axis.
