ABSTRACT:
Fuel injector for an internal combustion engine which has a timing chamber bore in its body intersecting at an acute angle with an auxiliary bore. These bores are fuel-receiving passages exposed to the pressure of injection. A radiused intersection between the walls of the respective bores reduces the concentration of stress within the fuel injector, allowing the injector to withstand the high injection pressures of mechanical pressurization. An electrochemical machining method and fixture for machining the intersection between the bores of a fuel injector body or other workpiece is also disclosed.
