The means being metering valves throttling fuel passages to injectors or by-pass
Official title: the means being metering valves throttling fuel passages to injectors or by-pass valves throttling overflow passages, the metering valves being actuated by a device responsive to the engine working parameters, e.g. engine load, speed, temperature or quantity of air (the means varying fuel pressure in a fuel by-pass passage, the pressure acting on a throttle valve against the action of metered or throttled fuel pressure for variably throttling fuel flow to injection nozzles F02M69/26)
F02M69/18 (The means being metering valves throttling fuel passages to injectors or by-pass) appears on 238 US grants and 28 published applications in this corpus.
