Motronic: L-Jetronic and fully electronic ignition systems in a single control unit, 1979

When it was launched in 1979, Motronic was the world’s first large-scale series-produced hybrid electronic gasoline injection and ignition system – introducing one of the first microcomputers in a car. It controlled the amount of fuel injected, the ignition timing, and other parameters by using a large number of criteria, e.g. gas pedal position and engine temperature, which had to be recalculated for each and every ignition process. The result was optimized fuel consumption and emissions, and smooth running. The first car to feature Bosch Motronic was the BMW 732i.
