Fuel Distributor Sequential Order

[zalsaigh]

I would like to know how the fuel distributor in Bosch mechanical injections system works (for Mercedes, 1980 450 SL). Does it work by distributing fuel in sequential order starting from cylinder #1 to 8? How the fuel distributor hooked up to the injectors. I can see that #1-4 on the fuel distributor are hooked up to cylinder 1-4 in order, however, #5 on the distributor is hooked up to cylinder 8 rather than #4 (according to the engine numbering system). Also #8 on the distributor is hooked up to cylinder #4. So, the distributor 4-8 is not hooked up in order to cylinder #4-8. Would it matter which # on the distributor connected to what cylinder #? Thank you.

The fuel is distributed exactly as the name implies...continuously. CIS is the acronym for Continuous Injection System. It is a very simple system, your car will be equipped with K-Jetronic with Lamba. European models were equipped K-Jetronic without lamba. Google "CIS" and you will get some good reading material that will help you better understand the workings.

I have an European model (260E 1988,w124) equipped with K-Jetronic without lamba and without catalysator.

Is the lambda sensor simulated in the ECU? or is it just ignored?

The lambda sensor can't be ignored if it doesn't exist in the system to begin with. Your system is "computer free."

Here's a link to the official Bosch Technical Information Sheet for K-Jetronic which describes CIS with/without lamda.
