Since their introduction, Jetronic f uel-injoction systems have proved themselves millions of times over under the harsh conditions of everyday driving.

The on-going development of the control unit and the sensors has led from the D-Jetronic to the L-Jetronic, and resulted in this fuel-injection system becoming even more precise and reliable.

New circuitry for the evaluation of the sensor signals has led to more economical and more sophisticated engine operating characteristics. Thanks to the employment of the Lambda sensor, and the integration of the Lambda closed-loop control unit, the L-Jetronic can already comply today with the exhaust-gas legislation of tomorrow. This booklet tells you all you want to know about the latest developments in the L-Jetronic.
