The control pressure is regulated with a mechanical device called the control pressure regulator CPR or the warm-up regulator WUR. Please activate cookies and refresh your browser. Electronically controlled mechanical fuel injection. This is a simplified and more modern variant of L-Jetronic.

Training Training is available at the following dates: These cookies are necessary for the website. L-Jetronic manufactured under license by Japan Electronic Control Systems was fitted to the Kawasaki ZH1the world’s first production fuel injected motorcycle. Vehicle usage The vehicle usage lists can be found fyel the tab “Downloads”.

The engine and all the components were working, just wanted to do the swap. The computer selects the closest one, with all of your order. OBD-II and immobiliser functions. Instead of injecting fuel into the intake, this injector allows fuel to bypass the fuel distributor, which varies the fuel pressure supplied to the mechanical injection components based on several inputs engine speed, air pressure, coolant temperature, throttle position, lambda etc.

The fuel distributor is mounted atop a control vane through which all intake air jefronic pass, and the system works by varying fuel volume supplied to the injectors based on the angle of the air vane in the air flow meterwhich in turn is determined by the volume of air passing the vane, and by the control pressure.


Fuel distributor – system-pressure regulator A usage list can be found in the tab “Dowloads”.

Jetronic is a trade name of a fuel injection technology for automotive petrol enginesdeveloped and marketed by Robert Bosch GmbH from the s onwards.

LE2 —featured cold start functionality integrated in the ECU, which does not require the cold start injector and thermo time switch used by older systems.

The lack of processing power and the unavailability of solid-state sensors meant that the vacuum sensor was a rather expensive precision instrument, rather like a barometerwith brass bellows inside to measure the manifold pressure.

Despite physical similarity between L-Jetronic components and those produced under license by other manufacturers, the ffuel systems should not be called L-Jetronic, and the parts are usually incompatible.

The final car to use K-Jetronic was the Porsche Turbo 3. Although conceptually similar to most later systems with individual electrically controlled injectors per cylinder, and pulse-width modulated fuel delivery, the fuel pressure was jetronnic modulated by manifold pressure, and the injectors were fired only once per 2 revolutions on the engine with half of the injectors being fired each revolution.

Jetronic – Wikipedia

Articles containing German-language text All articles with unsourced statements Articles with unsourced statements from May With the electronics disconnected, this system will operate as a K-Jetronic system. In the boscj, air flow into the engine is measured by a moving vane indicating engine load known as the volume air flow sensor VAF — referred to in German documentation as the LuftMengenMesser or LMM.

Product information The primary pressure regulator that is installed in the fuel distributor housing maintains a constant pressure in the fuel system of boscy K-Jetronic. Just removed from my Classic Saab 8V Turbo.

A genuine part is a part in Main unit has a crack on one corner,see last picture, you can replace it with the old one. Browse Related Browse Related. Jetrojic always had adaptive closed-loop lambda control, and due to the simple engine load sensing, it is heavily dependent on the lambda sensor for correct functioning.

Analog fuel injection, ‘D’ is from German: Verify that the item fits your car. Franz Fehrenbach Gottlob Honold. There are no sensors for air flow, or intake manifold vacuum.

Skip to main content. There are several variations of the technology offering technological development and refinement. LE1, the initial version. The system is based on the K-Jetronic mechanical system, with the addition of an electro-hydraulic actuator, essentially a fuel injector inline with the fuel return.
