What is VW CIS?
(Audi 80, VW Rabbit, Scirocco, etc.) CIS, or continuous injection system, is a method of fuel injection which is very different from modern cars. On a CIS engine, the air intake lifts a plunger, and fuel is injected in varying quantities depending on the position of the plunger.

How does Bosch K Jetronic work?
The fuel distributor is mounted atop a control vane through which all intake air must pass, and the system works by varying fuel volume supplied to the injectors based on the angle of a moving vane in the air flow meter, which in turn is determined by the volume of air passing the vane, and by the control pressure.
What does the G in GTI stand for?
Grand Tourer Injection
Meaning of GTI Acronym in VW Golf GTI The GTI in the Volkswagen GTI — as well as other cars with the GTI acronym — stands for Grand Tourer Injection. It originates from the Italian Gran Turismo Iniezione. Generally speaking, the GTI acronym indicates that a car has a direct fuel-injection system.
What is the difference between K-Jetronic and KE-Jetronic?
KE-Jetronic is a combined mechanical-electronic gas injection control system with a closed-loop lambda control. As can be inferred, the essential difference between K-Jetronic i KE-Jetronic The system has an encoder and a control unit that processes the data received from the encoder.
How do you adjust K-Jetronic fuel injection?
Remove one injector line from the top of the fuel distributor, and while looking into the injector port in the top of the fuel distributor turn the mixture adjustment screw clockwise until the port just starts to fill with fuel then turn the mixture screw 1/2 turn counter clockwise.
How does Volkswagen’s continuous injection system ( CIS ) work?
(Audi 80, VW Rabbit, Scirocco, etc.) CIS, or continuous injection system, is a method of fuel injection which is very different from modern cars. Fuel is continuously sprayed, not in short pulses at specific intervals like newer cars.
How does a CIS work on a car?
Air intake leaks are a nuisance on any car, but can be especially problematic for your CIS. On a newer car, air intake is metered by either a mass airflow meter, which reads the mass of the air coming in, or a manifold absolute pressure sensor, which does exactly what it sounds like.
What kind of metric system does Volkswagen use?
Since the Volkswagen Group is German, official internal combustion engine performance ratings are published using the International System of Units (commonly abbreviated “SI”), a modern form of the metric system of figures.
How is fuel metered in a CIS system?
CIS is a mechanical injection system because fuel is metered by the mechanical link between the fuel distributor and airflow sensor plate, which are linked together in one housing. In other words, fuel is metered in proportion to the incoming air flow.
