k-jetronic adjusting warm-up valve, system & control pressure on golf mk2 gti

[paulme33]

Thanks to you - ive sorted my xr4x4 speedboats engine as it was the little sreen or filter in the inlet part of the warmup regulator that was blocked and crap under it. this made the pressure go too high and so the cold start did not work.

Thanks for the video, I'm trying to get my head around Bosch fuel injection on a Saab 99.

GREAT STUFF! :D

Remember, don't let your T-handle hex wrench rest on the adjustment screw because it will weigh down the metering plate and throw off your CO adjustment readings.

thanks for the video!!

My 323i e21 runs only "good" because the injection is complitely original hehehe.I must do a recalibration...

@reserbil1

also to find out the mixture, think of the difference of the pressures. As i sold the car 2 years ago, i cannot tell you with certainty, but as i remember, increasing the dif. results to a richer mixture (as you saw, the control pressure starts at 1.5 bar, giving a richer mix for warming up.) So increasing SP or decreasing CP gives you richer mix.

The warm up line is not something that works only during warm up and it does not close up the line.. The warm up valve does 2 things: regulating the pressure for 2 minutes untilthe engines warms up, and controlling the pressure to a steady (3.4 bar) point after that . The difference of the 2 pressures is that matters. The "warm up valve" is kind of a wrong name. When i shut the switch, then i shut down the line and get a reading of the system pressure for a few seconds.

Do you know how to setup presure in ke-jetronic system?

[meremetia]

@MalutkaLol sorry, no!!



[sexycengiz5]

so if you remove washers you decrease system pressure am i rite?

[safedrivergr]

yes, as you "relax" the spring, you decrease pressure, as you tighten the spring (adding washers) you increase the pressure..

Be careful, the difference of the upper-lower compartment is that matters, not the actual pressure (5 or 5.3 or 5.5 bar etc) The difference is set by the warm up valve (3.4 bar on the warm-up when the system is at 5-5.2 bar)

Fantastic, very informative. I knew very little about these systems before watching this. Thanks.
