bosch l jetronic fuel injection manualThe injection has as function to provide the amount of fuel exactly dosed, necessary to the engine’s several working regimes. The LE-Jetronic command unit receives various input signals, from the various sensors that send precise information about the instant engine operation conditions. Then, the command unit processes this information received and calculate the appropriate fuel injection time, through an electric signal. This time is also known as injection time (iT). In the LE-Jetronic system, the injection valves spray the fuel simultaneously, what is to say, they are all driven at the same time. In this system, the injection command unit controls only the fuel system. The LE-Jetronic system is analog, and therefore it does not keep in memory possible damage that may occur. It has no fault lamp for the injection system. Without these cookies the website will not work properly. Please activate cookies and refresh your browser.

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.http://onomichi-tsukudani.com/fck_image/bosch-prosilence-66-manual.xml

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.http://chinastom.ru/userfiles/bosch-profimixx-47-manual.xml 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).http://fscl.ru/content/3m-case-sealer-manualThere 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.

We appreciate your patience. The heart of this system is the airflow meter, which measures the amount of air being required by the engine. In 1990 Bosch Motronic fuel injection replaced L-Jetronic on the Spider and 164 models. While the general operating principles are the same, Motronic offers more precise control over fuel and ignition events. When failures do arise, they are generally easy to diagnose. Here is a brief overview of how the system operates: Gasoline is supplied to the injectors by an electric pump. Two pumps are used on Spiders, one submerged in the tank, and one under the car in front of the tank. The pumps are controlled by the combi-relay. This relay is in turn switched on and off by a microswitch attached to the air flap inside of the airflow meter. At the end of the injector rail is a fuel pressure regulator that maintains constant fuel pressure. The regulator detects engine load by sensing manifold vacuum, and returns the unused fuel back to the tank. The injectors themselves are simply solenoid valves aimed at each intake port. The electronic control unit provides the high-speed ground that completes the circuit to the injectors. It determines the span of open time that will result in the ideal mixture for the particular conditions, based on the input from various sensors. The most important of these is the air flow meter, which is mounted between the air filter and the throttle plate. Info on operating temperature, rpm and exhaust gas oxygen content is also critical for accurate fuel metering, and is provided by the temperature sensor, the ignition pickup, and the oxygen sensor, respectively. An extra injector, the cold start valve, provides extra fuel into the manifold for starting. It is controlled by the thermo-time switch, which senses coolant temperature. The auxiliary air valve admits extra air during warm-up to provide decent idling. It is not a complete listing or a substitute for a proper shop manual. If there is less than 10 volts, the ECU shuts off. Once you’ve determined that the battery and battery cabling are in good shape, try the following. You will need a couple inches of wire. Cut the wire and tape it off going into the harness. Now, locate the main power relay next to the ECU. It has a large gauge red main power wire going into it. This provides more voltage to the starting circuit. To test, unclip the airflow meter from the air filter housing. The fuel pump should click on, accompanied by the sound of fuel rushing through the fuel rail. If this does not happen, check the fuel pump fuse. If the fuse is intact, the culprit is most likely the combi-relay. On V6’s, the combi-relay is on the firewall, and the fuel pump fuse is in the fusebox. On Spiders, the fuse and relay are under the package shelf, behind the seats. The cold-start valve is supposed to supply a very rich mixture upon initial start up when cold. To test it, remove the cold start injector from the intake manifold, place the nozzle in a container to catch the fuel, and turn the key to the start position. With the temperature of the engine below 95 degrees, it should spray. If not, check for voltage at each of the two terminals on the injector with the starter activated. If one terminal has voltage but the other doesn’t, replace the cold-start injector. If the wiring is OK, replace the switch. If neither terminal has voltage, repair the wiring harness between the starter solenoid and the cold-start injector. While not a cause for a no-start condition, the temp sensor is the most common cause of poor driveability and improper mixture. With an ohmmeter, check the resistance across the two terminals of the temperature sensor. You should realize the following resistance values at the temperatures given.

The address for this manual is: Bosch L-Jetronic Technical Instruction Manual As helpful as the forum and its members have been to me this past year as I have been restoring my '86 Spider Quad, I am glad to pay back a little of what has been given to me. Thanks, JP EFIflap ECU on fuel injected engines AFMadjust Come join the discussion about performance, parts, modifications, troubleshooting, maintenance, and more. It covers all Bosch fuel injection systems, including the D-Jetronic system found on Type 3s and the L-Jetronic system found on Beetles, Super Beetles, and Buses. Most of the complaints seem to stem from the fear of the unknown. Unfortunately, this fear results in the removal of a superior system from the engine and usually winds up with the owner replacing it with an inferior aftermarket carburetor setup. All you need for diagnostic tools is a fuel pressure gauge, a multimeter, and a manual. The Bentley manual does an excellent job of explaining FI diagnostic procedures. Most people blame ignition system problems on the fuel injection and go on a parts-replacing spree, unnecessarily wasting money. So it is imperative that before diagnosing the fuel injection system, the ignition system must be in tip-top shape and the engine must be free of vacuum leaks.

The smooth ceramic glass hob sur face is tough and durable as w ell as being practical and easy to clean. Induction hob Induction tec hnology is now widely recognised as one of the quic kest, safest and most efficient methods of cooking available. It uses an electromagnetic field t o instantly generate heat, giving you the contr ol and responsiveness of gas, but with far mor e energy efficiency. The hob will only operate wit h pans with a ferrous (or magne tic) base. Not e that when boost is selected f or a par ticular zone, the partner zone contributing the power canno t be used. Automatic pan recognition The hob recognises the size of the pan and only heats up the base of the pan and no t the whole zone, saving time and energy. Automatic boil start The cooking zone may be set t o operate at full power f or a period of time before reverting back to a pr e-set power level. Anti-overflow protection If liquid accidently ov er f lows ont o the control panel, the hob will aut omatically switch off allowing you the opportunity to clean up. Small utensil detection If you leav e a ser ving spoon on the induction zone when it is turned on, the hob will not recognise it as being suitable cookware. As an added saf ety mechanism, the hob will automaticall y switch of f giving you peace of mind. Energy saving Induction hobs are far more energy efficient than any o ther hob. This is because around three quarters of all the ener gy consumed is used to heat the pan. As a com parison, gas cooking actually only uses about 50 of the energy consumed to heat t he pan. The cooking zone also automatically de tects the size of the pan base so that heat is only generated thr ough the area in direct contact with the pan. Time saving Being almost twice as fast as a standard ceramic hob and up to 40 fast er than gas, the Bosch induction hob is ideal f or those with busy lifestyles.

Beautifully functional, per fect inf orm, they ar e designed to be the f ocal point of your kitchen. All models are electronically contr olled and feature electronic displa ys with soft-touch control k eys. The int ensive setting is ideal for int ensive cooking such as stir -fries.They last twice as long and are mor e energy efficient than standard lights. Some models also feature a dimmer function. Performance Ducted ex tr action Ducting out is the most effective met hod of extraction if the hood can be sit ed on an outside wall, or an outside wall can be reached via ducting. Recirculating extraction If an outside wall cannot be reac hed the extract or can be set up for recirculating. Air is drawn int o the appliance through the filters t o neutralise odours and remove grease particles. The cleaned air is then returned t o the kitchen. A carbon filter or recirculating kit is necessary for recirculation (optional accessory). Recirculating kit Contains a carbon filter and any o ther necessar y components to ensur e that odour free air is re tur ned into t he kitchen. T o ensure that the hood performance is maintained, the carbon filter should be replaced on a regular basis. Metal filter A metal filter pro vides the ultimate in filtering efficiency. The dishwasher -proof metal mesh requir es periodic cleaning but can be used over and ov er again. Paper grease filter The print and stripe markings darken considerably when the disposable paper filter is saturat ed to indicate that it needs replacing. Many hood models also feature an int ensive extraction setting, which gives an e xtra boost to the per formance of the hood when r equired. After running The hood automatically continues t o run on, for appro x ten minut es, af ter normal operation to ensur e that any remaining vapours and odours are effectivel y whisked a way. The hood then automatically switches off. Automatic switch back When the intensiv e setting is selected it may be set t o automatically re ver t back to a pre-defined normal level after a short period of time.
