High egt and blacksmoke.

01-18-2014, 11:29 AM #1I get a little high exhaust temperatures from my 606. About 8-900 degrees celsius under full load on 4500-6000 rpm. I got Precision 6766 turbo, 140cc Dieselmeken pump and runs 1,7bar boost. There is also a good amount of blacksmoke. Can pump timing do something with this?

return the pump timing to stock(my 602 is in atdc 15deg, idk same as 606)
and reduce the intake temp if you can
but.... my buddy's 7.5mm OM602 2.9L
About 1100~1200 degree c.
i don't think it's too high

I can help you out with all your manual transmission, clutch, flywheel, intake and exhaust manifold issues.
Just turn the boost up to 1.9bar and log the difference in EGT. Higher boost = lower EGT.

Wind up the boost, you can basicly lower the exhaust temp with enough air

cant get more boost.. pump is set on standard timing 15atdc

01-18-2014, 05:44 PM #5Needs stiffer wg spring then cant get more boost.. pump is set on standard timing 15atdc
well i did not like what happened after running my 605 at 800ºc , not much but one cylinder dead in idle , lots of white blue smoke, compression on the dead cylinder 10bar or less and the others around 14 , everithing points to valves burned.
i´m amased somebody run on 900ºc and didn´t face the same problems.

I know there are many threads on this, but cant find them.. What method is the best to check timing?
Maybe the turbo spools faster also if i advance it?

01-23-2014, 09:00 AM #9Prechambers are stock.. Maybe i should try to advance the timing ti 12 then?

I ran my 602 up to 1500+ F all the time and during the disassemble i found no issues or evidence of heat damage.
I think the problem for some of use if that you only know the overall exhaust temperatures. For example. say you have poor air flow to on cylinder or the pump is incorrectly balanced. You will get extreme heat on just one cylinder causing heat issues. Not that i think its practical to monitor all the cylinders for egt, but it is important to ensure your injectors are up to par and who ever did you pump can show the fuel flow being fairly even. I think at some point there could be an issue with the factor intake leaking or no providing enough air flow....but that's probably more for the extreme cases.
Just my thoughts!

01-23-2014, 03:02 PM #11I believe Duncan here have a point. Does the orginal OM606.910 intake deliver equal amount of fuel to each cylinder? Any experiences? Also have the standard crossover pipe.
anyway i will have to disasemble the think and i get u posted with the findings.

hy ,maybe u guys have a point. but belive me it is not a problem of injection unbalance or bad intake in one cyl, maybe and maybe is because i use my turbo waste gate simply closed , closed . and the head is a N/A one . probably is that 50ºC diff. and another i use to work with turbine engines and very few allow working temps above 850ºC, since turbine engines are heat engines u get my point.
