K-jetronic

A commonly used mechanical fuel injection system made by Bosch in which the amount of fuel injected continuously under pressure into the inlet ports is controlled by an airflow meter. Term used by Bosch to describe the original continuous injection system. The K is short for kontinuerlich, "continuous." Airflow i measured by a circular plate inside the airflow sensor part of the mixture control unit. Fuel delivery was purely mechanical, in relation to airflow, until 1980, i.e., there were no electronics used in the K-Jet system. VW, Audi, and Mercedes call it CIS
