via an admission valve that is opened and closed for each injection cycle the admission valve would preferably be operated via a separate electronic actuator although the illustrated examples show a needle control valve that is a three way valve that either connects the pressure communication passage to low pressure to high pressure other needle control valves could be compatible with the present disclosure for instance a needle control valve that opens and closes the pressure communication passage to drain in order to allow injection would also be compatible in this alternative the pressure control passage is always fluidly connected to the fuel pressurization chamber but by locating flow restrictions at selected locations that are known in the art the single two way needle control valve on the drain side can effectively control the pressure in the volume acting on the closing hydraulic surface of the direct control nozzle valve thus the disclosure is not limited to three way needle control valves but also encompasses any strategy and structure for direct control needle valves that effectively apply and relieve pressure on a closing hydraulic surface of the nozzle valve the present disclosure is not so much interested in how the fuel is pressurized for an injection sequence but rather that it is pressurized and de pressurized during each engine cycle although fuel injection systems according to the present disclosure can normally produce a relatively wide variety of flow rate shapes and injection sequences the present disclosure is primarily concerned with injection sequences that include a relatively small pilot injection followed quickly by a relatively large.
