MOTRONIC 2.8.1 - system description |
On model year 1994 and later Saab 900 cars with a normally aspirated engine, the MOTRONIC system will be fitted as follows:
• |
MOTRONIC 2.10.2 for the B206i
engine
|
• |
MOTRONIC 2.10.2 for the B234i engine
|
• |
MOTRONIC 2.8.1 for the B258i engine
Both MOTRONIC versions have sequential injection and individual control of the ignition timing when knocking occurs in any of the cylinders (these functions are adaptive). Expressed in simple terms, it could be said that the MOTRONIC system is a combination of a conventional electronic fuel injection system and an electronic ignition system with a knock sensor. The injection system features sequential injection while the power output stage of the ignition system is integrated in the control module. With the introduction of the Bosch MOTRONIC system, the earlier LH, CU14 and EZK systems will be discontinued. |
