Abstract (en)
[origin: ES8307336A1] An electronically controlled device for premetered pressure-time injection using high injection pressure and low feed pressure, which include one source (5-6) of medium pressure (MP) which is intermediate the high and low pressures, a two-stage rotary distributor which cyclically distributes the high and low pressure into single piping systems for each cylinder, a plurality of injection nozzles wherein, in each injector nozzle (30), a metering piston is provided (8) whose delivery chamber (21) is connected to the single piping system, and an injector control piston (11) having a control chamber (31) which is connected, via a three-channel electrovalve (9), through a medium pressure channel for the purposes of initiating injection, and through a second channel to the injection chamber (22) for purposes of initiating metering.
