Fuel Injector with Offset Nozzle Angle

摘要

A fuel injector includes a nozzle, a needle, and a pressure control section. The nozzle has first and second ends and extends along a first longitudinal axis from the first end to the second end. The nozzle includes a nozzle body defining a first longitudinal passage that extends along the first longitudinal axis and through the second end of the nozzle. The needle is disposed within the first longitudinal passage and is movable between a first position in which the needle prevents fuel from flowing through the second end of the nozzle and a second position in which the needle allows fuel to flow through the second end. The pressure control section extends along a second longitudinal axis that is angularly offset relative to the first longitudinal axis of the nozzle. The pressure control section includes an electromechanical actuator that actuates the needle between the first and second positions.

1. A fuel injector comprising:
a nozzle having a first end and a second end and extending along a first longitudinal axis from the first end to the second end, the nozzle including a nozzle body defining a first longitudinal passage that extends along the first longitudinal axis and through the second end of the nozzle; a needle that is disposed within the first longitudinal passage of the nozzle and that is movable between a first position in which the needle prevents fuel from flowing through the second end of the nozzle and a second position in which the needle allows fuel to flow through the second end of the nozzle; and a pressure control section that extends along a second longitudinal axis that is angularly offset relative to the first longitudinal axis of the nozzle, the pressure control section including an electromechanical actuator that actuates the needle between the first and second positions.
