The electronic unit injector 30 allows fuel to be injected into the combustion chamber with precise timing.

Electronic unit injectors are mechanically pressurized using electronic control of governing timing and metering functions. So use a larger gauge wire for lower voltage drop. Transferring fuel through.

If the overall height is 54 mm 2125 in proceed to step 9. The small size of the injector along with the trapezoidal valve placement in the cylinder head allows the EUI to be placed in the center of the combustion chamber for optimal fuel efficiency and low emissions. A unit injector UI is a high pressure integrated direct fuel injection system for diesel engines combining the injector nozzle and the injection pump in a single component.

Electronic Control Unit Fuel Injector Throttle Actuator Distributor Fuel Return gasoline only Fuel Tank propane or gasoline RPM Input Sensors. The HEUI fuel system is completely free of adjustment. N2 Electronic Unit Injector and Related Parts.

Determine which type of hold-down clamp is used by measuring the overall height. Series 60 Electronic Unit Injector Diagram The Electronic Unit Injector EUI is a lightweight compact unit that injects diesel fuel directly into the combustion chamber. The plunger pump used is usually driven by a shared camshaftIn a unit injector the device is usually lubricated and cooled by the fuel itself.

Adjustments to the components that are mechanical can not be made. The amount of fuel injected and the beginning of injection timing is determined by the ECM. Sistem bahan bakar EUI menggunakan supply bahan bakar bertekanan rendah dan kemudian menaikkan tekanan injeksi hingga 10000 sampai 30000 psi.

Fuel System C15 C16 and C18 - Caterpillar Electronic Engine Electric diagram of the basic fuel system typical example 1 Electronic unit injector 2 Solenoid for the fuel injection pump 3 Wastegate solenoid if equipped 4 Position sensor fuel injection pump 5 Fuel injection pump 6 Crankshaft position sensor 7 Boost pressure sensor 8 Fuel pressure sensor 9 Engine oil. Electronic fuel injector diagram Throttle body injection TBI system Working of electronic fuel injection system The throttle body injection TBI system uses one or two injector valves mounted in a throttle body assembly. The requirement for more flexible control of injection parameters gave rise to a new form of unit injector called the electronic unit injector in which the traditional P-L-N pumping element design has been replaced by a plain plunger and a high speed electromagnetically solenoid operated spill valve.

ELECTRONIC UNIT INJECTOR EUI The Electronic Unit Injector EUI injects fuel directly into the combustion chamber. The system controller adjusts when and how long the injector opens. It performs the same function as a conventional unit injector in an internal combustion engine such as in an on-road or off-road vehicle or a diesel-electric locomotiveThe pressurized delivery of fuel is camshaft-driven but the timing of the injectors internal operations are controlled by the.

When we start the engine the fuel pump will work so that the pressure fuel in. Changes in performance are made by installing different software in Electronic Control Module. ZzzEMS Slide 7 ZEEMS ZEEMS COMPONENT LOCATIONS 1.
