The steel sleeve for the spill valve must be precisely placed in an aluminum fuel bowl in order for the valve to work correctly. Also, the spill valve and fuel valve must be installed to very close tolerances. Custom machined spill valve pistons, steel sleeves, and fuel valves can be made to fit your worn or modified fuel bowl. This injection pressure is set by the manufacturer and depends engine to engine. A fuel injector consists of basically two main parts a nozzle and body. The nozzle and the injector body are made in pairs and carefully grounded to produce good quality oil seal. A fuel injector can achieve high pressure up to 500 bar by using spring loaded valve.If you decide to alter the fuel injection pump, you’ll need to: 1.

Two valve unit injector offers considerable flexibility in operation. If the needle control valve is held open when the spill control valve is closed then the nozzle behaves like a conventional spring-biased nozzle with opening and closing determined by the nozzle opening pressure (NOP) and nozzle closing pressure (NCP) respectively.An injection rate shaping nozzle assembly for a fuel injector is provided which includes a closed nozzle valve element and a rate shaping control device including an injection spill circuit for spilling a portion of the fuel to be injected to produce a predetermined time varying change in the flow rate of fuel injected into a combustion chamber ...Timing is also electronically controlled, which is done via a spill valve. The way the valve actually works is the same as the previous ‘VE type’ fuel pumps. Fuel pump pressure is applied to one side of the timer piston with a spring on the opposing side.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 phase1 Feb 1978 ... ... injector.
