It is known as K-Jetronic because the German word for continuous is "Kontinuous", and the system is hydraulic in operation. Control pressure opposes the movement of the air flow sensor plate, and break pressures within the fuel distributor and injectors are also hydraulic in operation.
What makes the K-jet less than accurate is the method of determining mass air flow which is simply the "floating body" principle -the sensor plate, placed into a stepped orifice. Impact air lifts (or depresses) the sensor plate in relatively close correlation to the mass air flow. It is not as accurate as the L-jet swing gate, and certainly less accurate than the hot wire sensor of LH and Motronic. Nonetheless the K-jet is tough and reliable, depending on very little electrical (heaters and sensors) once fuel pressure is provided.
It's old, it's obsolete, but like the wonderful SU carburetor, it works really well......
