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

Part Type Fuel Injector. Imprint Privacy Legal Bosch. 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 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.

D-Jetronic was a precursor of modern common rail systems as it had constant pressure fuel delivery to the injectors and pulsed injections, albeit grouped 2 groups of injectors pulsed together rather than sequential individual injector pulses as on later systems.

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. K-Jetronic debuted in the The injectors are simple spring-loaded check valves with nozzles; once fuel system pressure becomes high enough to overcome the counterspring, the injectors begin spraying. The primary pressure regulator that is installed in the fuel distributor housing maintains a constant pressure in the fuel system of the K-Jetronic.

Since the electric fuel pump supplies more fuel that is used by the engine, a valve in the pressure regulator opens and returns this excess fuel to the fuel tank.

Fuep licensed the concept to many automobile manufacturers.

There are no sensors for air flow, or intake manifold vacuum. The computer selects the closest one, with all of your order. Jegronic engine and all the components were working, just wanted to do the swap. 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.
