How does Bosch K Jetronic work?
K-Jetronic (1973–1994) K-Jetronic is different from pulsed injection systems in that the fuel flows continuously from all injectors, while the fuel pump pressurises the fuel up to approximately 5 bar (73.5 psi). The volume of air taken in by the engine is measured to determine the amount of fuel to inject.
How does K Jetronic fuel injection 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.
How does K Jetronic work?
An air enters to the air filter, then it enters into the engine cylinders through the air flow sensor and throttle valve. Therefore, the rotary-type fuel pump with electric drive supplies fuel from the tank. The fuel enters to the fuel accumulator through the filter.
When to replace the warm up regulator on a Porsche?
If sufficient voltage is available to the warm-up reg- ulator, and the warm control pressure still does not fall within the specified tolerance, replace the warm- up regulator. K-Jetronic Porsche to pressure gauge f to warm-up regulator KDEP 1034
What is a warm-up regulator?
The Warm-Up Regulator (WUR) is a rather misnamed and misunderstood unit. Sure, it does the function of an old school carby choke, to enrich the fuel mixture when the engine is cold, but it is also used to regulate the fuel Control Pressure when the engine is warm or warming up.
When to replace the warm-up regulator on a kjetronic vacuum cleaner?
K-Jetronic fall within the specified tolerance, check the vacuum source for a leak. If warm control pressure cannot be brought into specification, replace the warm-up regulator. Warm-Up Regulator with Full Load and Altitude Compensator.
What should I do if my Porsche K-Jetronic does not work?
If sufficient voltage is available to the warm-up reg- ulator, and the warm control pressure still does not Porsche K-Jetronic fall within the specified tolerance, check the vacuum source for a leak. If warm control pressure cannot be brought into specification, replace the warm-up regulator.
