Summary:A fuel injector for an internal combustion engine is disclosed. The fuel injector (10) includes a housing (20), a valve seat (30), a metering orifice (50), and a needle (40). The housing (20) has an inlet (210), an outlet (220), and a longitudinal axis (270) extending therethrough. The valve seat (30) is disposed proximate the outlet (220) and includes a passage having a sealing surface (330) and an orifice (320). The metering orifice (50) is located at the outlet and has a plurality of metering openings (530) extending therethrough. The needle (40) is reciprocally located within the housing (20) along the longitudinal axis (270) between a first position wherein the needle is displaced from the valve seat (30), allowing fuel flow past the needle, and a second position wherein the needle (40) is biased against the valve seat (30), precluding fuel flow past the needle. A generally annular channel (560) is formed between the valve seat (30) and the metering orifice (50). The channel (560) tapers outwardly from a large height to a smaller height toward the metering openings (530). A method of generating turbulence in a fuel flow through a fuel injector is also disclosed.
