In this video find out how to adjust the sensor plate if you experienced detonations which made your sensor plate resting too high, higher than usual, or if you out of who knows which reason hammered a wedge that regulates the starting position of the sensor plate height. If the sensor plate is too high or too low you will have vacuum leaks you won't be able to start your car easy and many other issues may arise. The detonations happen when the mixture is too lean - this is a common issue for those who drive their cars on LPG. The detonations can curve the sensor plate and then only the replacement is the solution. In this video I show what to do and how deep or high you can go when setting the height of the sensor plate. In some segments of this video I did it extremely high so DON'T DO THIS LIKE ME!!! I just wanted to show you what happens and how it looks like if you hammer the wedge too much. On some occasions you may curve the sensor plate when lowering it back. The last thing to do when you are done is to recalibrate the potentiometer because you changed the signal This is why this operation is very delicate and painful. Under normal circumstances you won't have to do this operation as well as nothing concerning the sensor plate except for the potentiometer replacement. Once again - DON'T EXPERIMENT ON YOUR CAR, IT CAN BE A BIG PAIN TO GET IT BACK RUNNING AS IT WAS!!!
Follow my advice and you will have a happy running car!
Happy Mercedesing!!!
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.
