CIS fuel distributor

I'm sure how far you took it apart, but I know they are designed to be disassembled, as you can add shims to modify the pressure.

Clean it up with carb cleaner, make sure there are no obstructions to the slits, and go for it: what have you got to lose?

FWIW, here's a link you might enjoy.

I've done it before and what do you have to lose? Put it back together and see what happens, OK? It really doesn't take too long to reassemble the unit if you have kept everything in order. If it doesn't work, then I'd get a rebuilt unit because if you get a used component, you just might have the same problem with all of the sediment and buildup.

You are wrong.

Very wrong.

This statement of yours is demonstrably inaccurate: "For once and all...K-Jetronic is "Electronic" with each injector being controlled electrically."

No.

Here's a good link:

The non-Turbos switched from mechanical to electronic in the early

Oh yeah, the electronic injection?

It's called LH Jetronic.

Next time, before you deign to chastise or correct someone, get your facts straight.

Otherwise, you look the fool.

The first Volvo fuel injection was electronic with an analogue computer. It was called by bosch D-Jetronic, D for Druck, German for pressure. It measured intake manifold pressure, and used that information along with engine speed information to calculate injection time.

Next there was K-Jetronic. This was non-electronic, K for Kontinuerlich, German for continuous. The injectors were always injecting fuel when the engine was running (even when the intake valve was closed), flow through them was varied by the fuel distributor, the signal from a plate moving in a venturi was transferred to the fuel distributor by a lever. There was a variation of this KE-Jetronic that was never used by Volvo, which basically added electronic control of the control pressure, and thus the mixture.

Also not used by Volvo was L-Jetronic. This was electronic, L was for Luft, German for air. Air volume was measured by a spring loaded door in the intake flow. Note K-,KE- and L-Jetronic measure air volume, not mass.

A variation of L was LH-Jetronic, the H for Heiss, German for hot. This used a heated wire in the intake flow to measure air mass, not volume. The computer calculated air flow by its cooling effect on the hot wire.

Then came various forms of Motronic, which combined fuel and ignition systems into one computer box.

Mike, I must thank you for that clear explanation of the various fuelling systems mentioned.

All the best, Peter.

Actually, I'd rather believe the Volvo shop manuals. Your handle says it all.

You must have misread the manual.

Facts are facts.

"Your handle says it all."

What, "zencraps?"

It's about casino play.

C'mon, "Administrator" (a douche bag name if ever there was one), you screwed the pooch big time on this one; just admit your error and move on.
