Wall effect injector seat |
摘要 |
A fuel injector is disclosed. The fuel injector has an upstream end, a downstream end, and a longitudinal axis extending therethrough. The fuel injector also has a body and a cylindrical needle. The needle is reciprocably located within the body between an open configuration adapted for permitting delivery of fuel from the downstream end and a closed configuration adapted for preventing delivery of the fuel from the downstream end. The fuel injector further includes a seat disposed proximate the downstream end. The seat includes a sealing surface engageable with the needle when the needle is in the closed configuration. The sealing surface has a seating diameter. The seat also includes a seat opening extending therethrough along the longitudinal axis. The seat opening has an opening diameter such that a ratio between the opening diameter and the seating diameter is less than 0.6. A method of generating turbulent flow in a fuel injector is also provided.
