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 "kontinuierliche Einspritzung" meaning continuos injection, 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(elektronische Gemischanpassung/electronically controlled mixture adaptation) 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 mA(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.
"Happy Mercedesing"

Hi. I found your channel when i got my first car. Im 21 and i bought an abandoned grey w124 230E and decided to fix it myself since i want to be a mechanic. The starts but wont idle. I changed the seized Fuel pump and fuel filter and now it starts more reliably but it still wont idle. I took out the idle air control valve and i dont think it works. I shook it and it doesnt make any noise and i applied direct power to it and nothing happened. Is the Idle air control valve the reason my car wont idle?

[@mercedeske]

Hi. Maybe one of them. The injectors, the potentiometer, etc.

[@zeropoint9474]

@@mercedeske i dont know about the potentiometer. im not sure where it is or what it does. as for the injectors it works. the longest we got it to idle for was around 10seconds and it backfired a good bit. im sure the fuel delivery is not the issue. but im sure the idle air control valve is not working
