ABSTRACT:
A fuel injector has an orifice member having an aperture for injecting atomizing and metering fuel. The orifice member is made of a plate material. The orifice member is machined to form the aperture. Then, the orifice member is processed by at least two shot blasting process in opposite directions to remove burrs and trim edges of the aperture. After the process, the orifice plate is inspected by measuring an actual flow rate of the aperture. Then, the orifice plate is processed by a shot blasting process again in accordance with the measured flow rate and a target flow rate.
