IGNITION COIL

The system is including a double coil (X), controlled by the electronic control unit (UCE).
The coil has and electric connector (Y) with four ways, and is simultaneously producing sparks at cylinders

1 and 4, when it is controlled by the pin 32 of the UCE injection and at cylinders 2 and 3, when it is controlled
by the pin 1 of the UCE injection.

Injection system

CHARACTERISTICS

• Electronic control unit (UCE injection) with 90 pins SIEMENS.

• Sequential multi-point injection.
• Controlling one injector each time.
• Static ignition with a double ignition coil.
• Canister purging valve controlled in opening duty cycle.
• Idling regime correction subject to:

- climate maintenance (air conditioning);
- battery voltage.

• Maximal regime:

- 6200 rot/min for first, second and third speed;
- 6000 rot/min for fourth and fifth speed.
