than 6,300rpm.
• Fuel will be cut off when ignition failure is detected by the system.
• When the system voltage is higher than 18V, the system will turn into electronic throttle
body functional restriction mode (forced idling mode).
• Fuel will be cut off during deceleration.
(9) Basic fuel injection constant
The basic fuel injection constant is to provide system with engine displacement and
nozzle flow.
(10) Battery voltage correction
When battery voltage changes, voltage correction will ensure correct fuel injection
volume.
Ignition Control Logic
1. Coil magnetization control
Ignition coil magnetization time determines the ignition energy of spark plug. If the
magnetization time is too long, it will damage coil or coil drive; if the magnetization time
is too short, it may cause a fire.
2. Start mode
In start mode, the system will adopt a fixed ignition angle to ensure the gas mixture in the
cylinder has been ignited and to provide positive torque: after the engine starts, its speed
will rise; after it goes into self-running, the ignition angle will quit start mode.
3. Calculation of ignition advance angle, see Fig. 1-12
