An improved starting fluid injection apparatus for an internal combustion engine includes a valved container of starting fluid, a valve actuator, an injector assembly, and a conduit interconnecting the actuator and the injector assembly. According to a first feature of the invention, a flow metering orifice is provided in either the actuator, or the conduit at a point spaced from the injector assembly, or the injector assembly. This orifice relieves constraints related to fluid metering from the injector orifice, and permits the use of a greater number of larger injector orifices than would otherwise be possible. Multiple flow metering orifices can be used upstream of the injector orifices. Additionally, in some applications it is possible to dispense with injector orifices entirely.
