Everything what you should know about the fuel distributor before disassembling it. This is the heart of the system called K(E)-Jetronic. The part is very complex and you need to know what you can should and what you mustn't do at any cost! If you replaced all the parts on the injection system and you still have a high consumption, bad idle, low power, shaky running engine or internal leaks and you can smell fuel in the engine bay, if the plunger is stuck(the sensor plate won't go down or get back up), if you turned the CO(mixture) screw counterclockwise to the max and you still have fuel flow or you bridged the contacts 7&8, you unscrewed the metal hoses from the distributor and you get fuel flow coming out of the ports without deflecting the sensor plate then you should know that it's time to disassemble the fuel distributor in order to clean it, replace the ruptured diaphragm, the o-rings inside of the barrel, on and in the lower chamber of the distributor etc.

What am I talking about?
My topic is the KE-Jetronic injection system which I try to demystify as much as I can.
For all of you to understand the system in brief - Developed in 1973 and being mounted into cars up to 1993 as it went in history. But why these to letters!?(KE) K(from German "kontinuierlich" meaning continuos, without interruption) the MECHANICAL injection system on which the fuel starts flowing from the fuel tank sucked by the FUEL PUMP and delivered to the FUEL DISTRIBUTOR which sends fuel to the INJECTORS while the majority of it flows through the FUEL PRESSURE REGULATOR through its return line back to the fuel tank again. The letter E(electronic) has to mark the electronic sensors (the developement starting from early eighties) which had to inform the ECU about the current state of the engine so that the ECU(Electronic Control Unit) then could create current signal in mAmp(miliampers) and send it to four crucial components for the system - the EHA(the electro-hydraulic actuator,a unit consisting of a magnet, an electromagnet and a baffle plate) which had to fine tune the engine in each of its phases, the ICV(the idle control valve), the unit which was predicted for the engines perfect idle, the X11(the diagnostic socket) where the duty cycle(the ideal mixture) was adjusted and the X11/4(the code reader) - the socket which from any codes were read if present using an OBD1 scanner.
An extraordinary injection system which could be fully repaired in your own garage using a multimeter and a pressure gauge only for its fine tuning, together with some common tools.

Hello there. I recently bought 190 E 1,8 and iam watching your videos. I saw a video about the idle speed control valve and i tried to put it the way you showed us but the down hose doesn't fit .is short.

[@mrnice30001]

Hi, Did you make a video showing how to change the fuel pressure regulator?

[@mercedeske]

Not exactly. I just wanted ro make a difference between the fuel accumulator and the fuel pressure regulator. Both of them have symptoms of falling pressure.

[@AL-yg1li]

hello is that the settings of 3 1/2 turns on the valve distributor is valid for the engine of 2.3 16s thank you for your answer and thank you for your tutorials very very interesting

[@mercedeske]

Hello and thanks. If you want to experiment you can try with 3 1/4 turns. Set it up until you get 100ml per minute per section on full throttle while on idle you will have to get 4ml per section and the tolerance to be as lower as possible(below 10%, so below 0.4ml) as lower as possible. Best regards and Happy Mercedesing 😊

[@AL-yg1li]

thank you et again Congratulations on your knowledge

My pleasure Happy Mercedesing 😃🍀

Is it good idea to just ultrasound the fuel distributor? I don't want to rebuild(disassemble and reassemble ) the fd

[@mercedeske]

I have already had a guy on the channel that wanted to clean the fd with vinegar without disassembling the fd. Let me make you a comparison concerning that statement - that would be the same thing as if you wanted to take a shower - could you wash off everything entirely from your body without taking your clothes and socks off!?

[@henrysalem5516]

Hi, You measured 12.3 mm on the four Differential Pressure Screws, what happen it you would have 12.4? Is there any other adjustment to compensate this?

[@mercedeske]

At first, measure the fuel flow. You must get equal amounts both on idle and full throttle if you have readjusted the screws.

[@salehfiras943]

What should be the raw pressure value and systemic pressure value? and the difference between them?

[@mercedeske]

For 4 cylinder cars the raw pressure 5.7-5.9bar and the system pressure 5.3-5.5bar(for 0.4bar less/the ideal difference).

[@carlosramirez-vt3vc]

Maestro el EHA necesariamente tiene q llevar corriente xq yo veo q cuando le llevo corriente directa de la batería el manda mucha gasolina a los inyectores q es lo contrario cuando no tiene corriente prácticamente no llega la gasolina a los inyectores.

[@CaptainTBone]

I took the top hoses off on my 190e and 3 of the ports are not filling up with fuel. Could this cause a bad idle?

[@mercedeske]

Of course

Hola desde España Tengo un Mercedes 300e w124. El combustible llega a la cámara superior del distribuidor pero a veces por uno no llega al inyector. De que puede ser? Tengo video donde se ve. Muchas gracias por adelantado. Un saludo

Hola. Puedes enviar el vídeo. O la línea de retorno está obstruida o no hay diferencia de presión y, por lo tanto, no se puede realizar la medición. Saludos desde Serbia

Hello. I have to do this also 😩 the screw for spring. Is this for 6 cylinder the same? 3,5 rounds? Thanks.

[@mercedeske]

Hello, better set it to 3 1/4. This doesn't mean you are going to get a good idling so as you mount the distributor you will have to find 6 glasses and a measuring cup(100ml). You will have to do the quantity comparison in one minute. In that minute you have to get 4ml fuel on idle per section - the maximum discrepancy between the cylinders must be 10% at most, the lower the better. The ideal is 2.5% or 0.1ml (5drops of fuel). The closer the numbers to each other the better your car is going to be idling. Fingers crossed!

Which throat 🤔 which part do you exactly mean?

[@mbmechanicmike5193]

@@mercedeske sorry I forgot to write 🤦 from the bottom between plunger and the nut

Yes, that seal ring. Yes, it can start leaking. It you doubt it, then replace the seal ring. It costs 13€ in the dealership as well as on ebay as far as I know.

[@vishnukalainesan]

Hi I just want to ask what is considered high fuel consumption for these m102 engines like in L/100km or mpg etc?

[@mercedeske]

Well, it would be 12l/100 at about 80km/h on the freeway or 18 in the town approximately. It doesn't mean that the fuel distributor is the issue-the issue can be injectors, oxygen sensor, sensor potentiometer, the fuel pump. Regarding the fuel distributor, it should be the very last thing in the row to check if everything is replaced and the consumption is increased.

[@vishnukalainesan]

@@mercedeske thank u for the reply. So my car is a w124 230e and I have replaced injectors, intake manifold gaskets, etc. My fuel consumption is not bad at all just a little on the high side that's it. I know my accumulator is gone so I'm replacing that in the near future. The car has hot start problems. Would the fuel pressure regulator be a culprit aswell?

[@mercedeske]

@@vishnukalainesan The fuel accumulator. Connect the pressure gauge to the distributor when the car is warm. As soon as the car is warm stall the car. The pressure MUST NOT FALL UNDER 3BARS IN LESS THAN 30 MINUTES. That's how you will know that your fuel accumulator is bad!

[@mercedeske]

Or, this is a faster way. Watch on the browser, there you will have subtitles. m.kzbin.info/www/bejne/h52Wi4uorbSMldE

[@vishnukalainesan]

@@mercedeske thank u will watch it. So basically the car has a flat acceleration not to the point where its a turtle but its flat ish. Now I do not know if the m102 is underpowered as this is my first w124 with a 4 cylinder motor. I had 2 w124s all were the 300Es.

Ciao mister come stai... Allora ho aperto il carburatore e ho cambiato il guarnizione quella fine tipo un foglio, e ho chiuso dinuovo quindi parlò del cuore del motore diciamo, . Adesso quando accendo la macchina consuma tanto benzina? Ieri lo ho acceso 5 minuti a finito 20 litri di benzina?. Sicuramente il problema è che io non ho chiuso bene il carburatore... Cosà deo fare lo apro di nuovo e lo richiude ma non so esatto cosà devo toccare per mettere apposto di poter non consumare la benzina in questo modo assaggiato. Grazie mille. Vorrei mandarti delle foto per spiegarti meglio

[@adriatikozoreanu8987]

Ciao maestro come stai tutto bene.. Ho aperto tutto il carburatore e ho trovato un tappo bianco Rota, ho messo un altro tappo. Adesso non và in motto? Tenda di partite ma non parte? Misa che non li và tanto benzina? Non lo so dove si apre e si chiude la benzina? . Dammi una mano. Grazie mille

[@mercedeske]

Ciao tutto bene grazie. All'inizio, mentre rimonta il distributore, dovrai far funzionare la pompa del carburante (non colleghi i tubi che portano agli iniettori) per assicurarti che il carburante non esca dal distributore. Se lo fa allora qualcosa non va con il diaframma o con 4 o-ring neri sulla canna. Ok, allora mandami quelle foto su Instagram. Qualcosa di strano sta accadendo sul mio gruppo fb. Un video anche se possibile.

Check the parts on the system - the fuel pump, injectors, fuel filter, potentiometer and the lambda for the beginning and make sure you have a steady fuel pressure while the car is on.
