- Precise dosing of the amount of fuel at each load mode, resulting in low fuel consumption and good power balance.
- Reduction of harmful components in exhaust gases thanks to precise fuel metering and the possibility of cleaning exhaust gases in the catalytic converter, controlled by signals from the oxygen sensor.
- Self-diagnosis of the injection system control unit, which allows for quick detection of defects.
- The petrol injection system is equipped with a fault code memory. If any faults occur in the ignition or injection system during operation, the corresponding codes are recorded in the memory. If the injection system or engine do not operate perfectly, the fault codes can be printed out when reimbursing the costs of the service station.
Caution: When the battery is disconnected, the fault codes in the memory device are erased.
The injection system operates stably over a long period of time and requires virtually no maintenance. The exceptions are the air and fuel filters, which must be replaced in accordance with the maintenance chart. Important adjustment and repair work is carried out only with expensive measuring devices, so this work can only be carried out by appropriately equipped service stations.
Caution: When working on the injection system, it is necessary to observe both the cleanliness rules for fuel systems and the safety precautions when working on the ignition system, see page 47.
