L-Jetronic fuel injection system

An electronically controlled fuel injection system. Fuel is supplied by an intermittent-action L-Jetronic fuel injection system, which uses engine speed and intake airflow as its main control parameters. Each cylinder has its own solenoid injector, which is opened by control pulses delivered by the electronic control unit; the length of these pulses depends on the control parameters. All of these parameters are detected by sensors and processed in the control unit. This fuel injection system is employed by BMW in the K 75 model
