Injector spill valve meaning.

The controlled part of the injector is a solenoid-operated spill valve. Normally, it is open, allowing the fuel to return to the supply line when the pump plunger descends. When the solenoid is energized, the spill valve closes, and the fuel is forced through the spray tip into the cylinder. The four phases of EUI operation are: Fill phaseNich1019.

If this valve does not work you could be over fueling or run the risk of fuel cooking in the injector making a mess of the spray pattern. It should be telling you which injector is throwing the code and if it is one of the two that were worked on take it back. The injector pipe leaking might mean one injector doesnt get the pressure it needs - these are 2 stage injectors, so one piston might be running lean. ...

The pumps are similar but the spill control valve on mine is different. Extra fuelling on mine could only be achieved with a piggy back computer. I believe yours is a mechanical valve (hence the provision for adjustment) with the wires being for the fuel cut off. The version on my pump is an electrical solenoid with no means of mechanical ...

magnetic traction causes the spill valve to close the spill port, thus trapping the fuel in the No. 1 plunger barrel. The rising pressure in the plunger barrel opens the delivery valve No. 1, and the plunger No. 1 displaces the fuel through the open delivery valve to the injection line. During this period the plunger No. 2 continues itsWhen the engine moved to electronic controls ('981/2-'02), the injection system switched to a vP44 rotary-style pump before being converted to commonrail injection in 2003 and receiving the Bosch ...Consult the appropriate repair manual or repair database for the exact code definition.
