Jetronic systems were found on a number of vehicles, who uses them now?

Asked by migration_judge_roy Feb 20, 2013 at 10:10 AM about the 1977 Datsun 810 Base

Question type: General

Would like to have a GURU explain the functions of these little known jetronic component parts. As one is trying to diagnose acceleration troubles with a VW Quantum for example would prefer to actually know the said function of the device I'm disconnecting for experimentation purposes. Components of the KE-Jetronic: 1. Air-flow sensor 2. Mixture-control unit 3. Fuel distributor 4. Pressure actuator 5. ECU 6. Fuel filter 7. Fuel accumulator 8. Electric fuel pump 9. Fuel injection valves (injectors) 10. Throttle-valve switch 11. Thermo-time switch 12. Cold-start valve 13. Engine-temperature sensor 14. Auxiliary-air device 15. Primate-pressure refulator

PRIMATE PRESSURE REFULATOR, I'm reflecting on a chimp who was using his seeking his own refreshment.

I was cast into the Porsche 914 pool of excellence, and alls I could think of was the jetronic carb that I was guessing this one had. Wish I could speak with authority on this but I've had a number of cars that had it. My datsun, Volvo, Nissan....wiki says:Porsche, Volkswagen, Audi, BMW, Mercedes-Benz, Rolls-Royce, Bentley, Lotus, Ferrari, Peugeot, Renault, Volvo, Saab, DeLorean and Ford automobiles. The final car to use K-Jetronic was the 1994 Porsche 911 Turbo 3.6.

Am I mad to want to understand the intricacies of this? they have moved on to a more sophisticated way of doing things now.

The K-Jetronic was very good for its time. No two ways about it. Basically, a very simply, but elegantly engineered and extremely well made system. There is no real mystery to it. Each of the parts does exactly what you would expect, given the name. If you are trying to fix one for the first time the shop manual is an absolute must, but the actual repair is very straight forward. Learning how to keep the system working right is always a good idea, and it preserves the body of knowledge that otherwise could well be lost.

yes it was very good in fact i think better than todays electronics, today too costly for a low priced car, simply put the intake suction lifts the thin disc inside and raises fuel pressure and the injectors are such that more pressure lifts the needle seat for more fuel ,lift the rubber boot cap ,check that disc is free to move up,down with no rubs,hydrolic lever, adjustment is thrue 3/16 hole square tip driver 2 inch in hole for idle speed
