The 1300 series electronic engine uses injector units,
which are hydraulically actuated and electronically
controlled.
This offers vastly improved performance over
mechanical systems by controlling the following areas:
The rate of injection can be controlled to meet any engine condition, due to the
injector being hydraulically actuated rather than mechanically.
The rate of injection and injection pressure does not depend on engine speed.
Both start and end of injection is electronically controlled, unlike conventional
electronically controlled mechanically actuated unit injectors, the plunger does not move until the solenoid is energised.
This means that plunger movement is not limited to the speed or duration of a cam lobe.

The injector uses the hydraulic energy of
the pressurised oil to cause injection.
The pressure of the incoming oil controls
the speed of the intensifier piston and
therefore, the rate of injection. The amount
of fuel injected is determined by the duration of the pulse from the ECM and how long it keeps the solenoid energised. As long as the solenoid is energised and the poppet valve is off its seat, oil continues to push down the intensifier and plunger until the intensifier reaches the bottom of its bore.

An intensifier piston in the injector
unit multiplies hydraulic force on
the plunger.
By varying the hydraulic input
pressure, injection pressure can
be controlled in a range from
3,000 to 21,000 psi.

Flashing Lights
To interrogate the ECM’s memory or identify a fault,
the self test button (Green) should be depressed.
The (Red) button should be momentarily depressed to initiate
the active and inactive fault tests.
If there are any active faults, the red lamp will flash once,
followed by the amber lamp flashing a numerical code.
If more than one active fault code is stored in the ECM’s
memory, there will be a short pause after the first code and
then the next code will be indicated.
When all of the active codes have been indicated the red
light will flash twice and the inactive fault codes will be flashed.
At the end of the sequence the red light will flash three times to
signal the end of the test.
