Reload to refresh your session. Bosch licensed the concept to many automobile manufacturers. There are several variations of the technology offering technological development and refinement.Originally, this system was called Jetronic, but the name D-Jetronic was later created as a retronym to distinguish it from newer versions.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 barometer, with brass bellows inside to measure the manifold pressure. 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. This system has no lambda loop or lambda control. K-Jetronic debuted in the 1973.5 Porsche 911 T in January 1973, and was later installed into a number of Porsche, Volkswagen, Audi, BMW, Mercedes-Benz, Rolls-Royce, Bentley, Lotus, Ferrari, Peugeot, Nissan, Renault, Volvo, Saab, TVR and Ford automobiles. The final car to use K-Jetronic was the 1994 Porsche 911 Turbo 3.6.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. The control pressure is regulated with a mechanical device called the control pressure regulator (CPR) or the warm-up regulator (WUR).
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.A variant of K-Jetronic with closed-loop lambda control, also named Ku-Jetronic, the letter u denominating USA. The system was developed to comply with U.S.A. state of California's California Air Resources Board exhaust emission regulations, and later replaced by KE-Jetronic.The engine control unit (ECU) may be either analog or digital, and the system may or may not have closed-loop lambda control. 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.The later KE3 (CIS-E III) variant features knock sensing capabilities.L-Jetronic was often called Air-Flow Controlled (AFC) injection to further separate it from the pressure-controlled D-Jetronic — with the 'L' in its name derived from German: luft, meaning 'air'. In the system, 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. Licensing some of Bosch's L-Jetronic concepts and technologies, Lucas, Hitachi Automotive Products, NipponDenso, and others produced similar fuel injection systems for Asian car manufacturers. L-Jetronic manufactured under license by Japan Electronic Control Systems was fitted to the 1980 Kawasaki Z1000-H1, the world's first production fuel injected motorcycle. Despite physical similarity between L-Jetronic components and those produced under license by other manufacturers, the non-Bosch systems should not be called L-Jetronic, and the parts are usually incompatible.The ECU was much cheaper to produce due to more modern components, and was more standardised than the L-Jetronic ECUs.Initially designed for the US market.

This air mass meter is called HLM2 ( Hitzdraht-LuftMassenmesser 2) by Bosch. The LH-Jetronic was mostly used by Scandinavian car manufacturers, and by sports and luxury cars produced in small quantities, such as Porsche 928. LH-Jetronic 2.4 has adaptive lambda control, and support for a variety of advanced features; including fuel enrichment based on exhaust gas temperature (ex.This system features one centrally positioned fuel injection nozzle. In the US, this kind of single-point injection was marketed as 'throttle body injection' (TBI, by GM), or 'central fuel injection' (CFI, by Ford).There are no sensors for air flow, or intake manifold vacuum. Mono-Jetronic 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.By using this site, you agree to the Terms of Use and Privacy Policy.

If this cannot be felt, the plnu ger is not moiv ng freel,y (see belo)w. Flu ly lift the air flow sensor plate up to its maix mmu deflection. When released, the sensor plate must fall back to its rest position after bouncing once or twice on the spring stop. If not, the air flow sensor plate is not moiv ng freel,y (see below). If the air flow sensor plate does not move freely, loosen the monu ting screws aronu d the air flow sensor hosu ing to check if hosu ing aw rpage is casu - ing the lever to bind.

If the sensor plate touches the sides of the funnel, loosen the sensor plate fastening screw.
Hold the fasten- ing screw iw th pliers to preev nt the plate from moving donw as shown. When the giu de ring is in place, tighten the fastening screw to 5.0 - 5.5 Nm (3.7 - 4.0 ft Ibs). Then, loosen the screw and retorqeu the fasten- ing screw again to the same value. The air flow sensor plate msu t not now be able to be turned by hand. Bridge the electric safety circiu t (see Electric Wiring Diagram). Siw tch the ignition on for 10 seconds to apply control pressure to the plnu ger. The upper edge of the sensor plate should be flush with the beginning of the upper cone as shonw. The upper edge of the sensor plate may be as much as 0.5 mm below the beginning of the pu per cone, btu must NOT project up into the cone at all. Adjust the sensor plate position by removing the air filter and bending the iw re loop on the spring stop (arro)w or turning the adjusting screw (1). Remoev the air filter from the air flow sensor.
