Genius. I love when math is applied to engine function. Thank you. As an ex-engineer, this video blows away everyone else’s on the subject on the net and helps a lot! 🙌

Thank You for such a fantastically informative video. The Bosch German engineers who designed this system were so far ahead of their time.

excellent video, and I'm really looking forward to the finished calibration equipment and its operation!

They make calibration fluids used for fuel system testing without all the dangers

Truly terrific video. Thank you for sharing your invaluable knowledge!

Great video, very interesting good luck with project. 🍀

Interesting what you say about the necessity to rebalance the ports after a rebuild. Makes me wonder how many of the rebuild companies actually do this.

Hi, i really love your videos because they have contain much useful information that you cant find elsewhere! Do you by any chance have the flow values for this? (I already tried finding information on this but without luck) And maybe a recommendation for the flow measuring device? I have a M103 that i tested and (if broken) replaced everything (including every sensor, eha, resealed the fuel distributor, injectors, seals, rubbers, even the caps on the ecu, etc....) but i just cant get it to run right (High fuel consumption (over 20L/KM) and under certain loads high pitched vibration on the gas pedal). I also measured the pressures and adjusted the duty cycle. I also measured the differences in flow between each cylinder but they are pretty even (~3-4%). I even bought a wideband lambda tool but under full load a weird symptom is showing -> It starts at like Lambda ~0.92 at 2000rpm and ends up at ~0.77 at 5500rpm, so way too rich. Maybe you know a way to make that curve flatter? Maybe with these adjustment screws? Many thanks in advance from germany!

Thx for your video, very interesting about Bosch historical information ! isn’t it possible to calibrate by juste measuring the volume of fuel of each cylinder during an amount of time and calculate the flow (at different level of the plunger) ? It will be cheaper (but longer) then expensive flow meter ? But perhaps it is not accurate enough.

The plunger on my 230E k-jet has a clip to retain it. The clip simply bends to stop the plunger dropping out so theres no freeplay in the venturi plate. There doesnt seem to be anyway to set the resting position of the plunger.

hello sir what ratio of citric acid to water should be used to clean a fuel divider in an ultrasonic cleaner?

Hi Peter. I have a used fuel distributor I just got off eBay. The plunger is sticky. What would you recommend to use to unstick it? I plan on putting this one on my car to see if it works. Thanks

Hi Peter. I rebuilt mine and discovered the internal filter where the barrel plunger sits has a hole in it. I couldn’t find a replacement for that. Next when I was putting the springs and discs the divider tipped over and they all got mixed up from their original locations. I did remove the hex screws for cleaning but didn’t mess with the flow rates. Is it game over since all the springs and cups aren’t in their original locations?
