The injection manual describes the operation as:
"The duration of injection (fuel quantity) is governed
basically by two factors: engine speed and load condition
of the engine. The engine speed is relayed to the control
unit by the distributor contacts I and I I. The load condition
is determined by measuring the absolute pressure in the
inlet manifold. This pressure is converted to an electrical
impulse and relayed to the control unit by the pressure
sensor 0 , which is connected to the common inlet
duct 0 by a hose (A).
The control unit processes this information and gives a
signal for the injection valve to be open for a longer or
shorter period of time (F). The control unit thus permits,
by electrical means, a varying quantity of fuel to be passed
through the injection valves depending on engine load and
speed. This is how the “basic fuel quantity” is governed."
Can you tell from this whether it is peak and hold or saturation?
