The amount of fuel is controlled through the injector nozzle (governed by the throttle position-RPM). The
dosage is refined through different adjustment parameters. The following parameters are used for the
calculation of fuel ratio-amount of injection:
Throttle position
RPM
Ambient air temperature
Barometric pressure
Engine crankcase temperature
Acceleration rate
Manual manipulation (optional)
1.3Description of the Ignition System
The ignition system (Figure 1.3-1, 1.3-2) consists of an armature plate, a magneto, E-Box(s), ignition coils
and the ignition cables with the required number of spark plug leads. The ignition system is completely
electronic and possesses an E-PROM for a freely programmable ignition curve however, this can only be
carried out by the manufacturer. Alternating Current (AC) power for electrical components during running
and charging of the battery is provided. The engine is available with a single or dual ignition system
installed.
An electronic stator plate is secured on the ignition side with the crankcase. A magneto is fixed on the
crankshaft and encloses the armature plate. The fan housing covers the ignition system?s magnetic wheel.
The electronic E-box and ignition coils are mounted on a fixture plate secured to the crankcase as shown in
figure 1.3.3.
