ABSTRACT:
In order to permit a simplification of the crankshaft rotation sensor device which provides the computer of the control system with angular speed and position information for ignition and/or fuel injection timing, a signal generated by one pickup for every two engine cylinders from a single reference mark on the crankshaft is formed into a signal pulse which is used to trigger the counting of clock pulses from a clock into a counter. These are then periodically transferred to a computer as a numerical signal which represents the required information. In a first mode the counts are transferred every other period between pulses and the counter counts in the cycle periods between the pulses in which the counter is not transferring to the computer. In a second mode, the counter counts every cycle between pulses and the counts are transferred during every pulse itself. There is also described a system which includes additional circuitry by which below a certain speed of the engine the system operates in the first mode and above that speed operates in the second mode.
