Dirty Common Rail Injectors

Dirty Common Rail Injectors.



There are many Cummins guys now days who have a concern about the particulates emitting out of the tailpipes of their Mighty Dodge Cummins Turbo Diesels. With all the scrutiny we all are under and emissions testing common throughout the USA.



This is just a little discussion about common rail injectors and the myth that ALL larger aftermarket injectors are Dirty. While there are some CR injectors out there that ARE filthy dirty, not all fall into that category. Done correctly, a larger than stock injector can offer much better flow efficiently AND remain clean.



On the real serious higher output injectors, one needs tuning and one needs to do it properly.



Enjoy this correspondence borrowed from a forum post.

Exergy gives, IIRC, something like 30 days to return your cores before then

charge you for them. So 100% overs from Exergy are still cheaper than BBi's.

I was also talking to Gordon and he was telling me Les was tuning a guy with

stage 3's and compound garrett's and they are very dirty. Said he had to do

a lot to get them to run half way clean. I'll stick with Exergy. Have yet to

hear/see any bad things about their injectors.

On the big ones good tuning is needed.



Another example. Take a look at these emissions testing sheets on a 2012 with stage BBi Stage 1. 5s. Lets let these sheets do the talking. This shows what a well engineered injector is capable of as far as emissions particulates go. http://smartyresource.com/images/2012 Emissions Test.pdf This truck is set up a bit simpler. Smarty JR on level 1 and all defaults. STG 2 compressor upgrade on the charger also.



This example should show that those wanting the best quality Injector for an efficient increase of power can have the power and run clean too.
