  • Dual-channel piezoelectric injector
    Patent number: 9447761
    Abstract: The invention discloses a dual-channel piezoelectric injector, including a dual-channel injector body, its bottom in turn is connected with an upper intermediate, a lower intermediate and a dual-channel needle valve body. At the top of the dual-channel injector body there are two tubing interfaces, and each tubing interface has a tubing fuel duct. There are two laminated piezoelectric actuators and two spray fuel ducts connected to two tubing fuel ducts respectively inside the dual-channel injector body. The upper intermediate and lower intermediate connected with each other to form the middle connection body. From top to bottom of the middle connection body, there is an external control fuel duct, an external spray fuel duct, an internal control fuel duct and internal fuel spray duct.
