04 model year trucks, are they all egr?

EPA emissions regulations got stricter on 10-01-02. The next stage was some time in 2007 then more in 2010. Sometime around 2005 or so the sulfur content of diesel fuel was (by EPA mandate) gradually reduced from 500ppm down to 15ppm (also, back in the mid 90's sulfur content was reduced from 3,000ppm to 500ppm). That reduction to 15ppm was necessary to reduce particulate matter and also because 500ppm diesel would quickly clog up and render useless any DPF. Although the DPF was installed on 2008+ heavy duty trucks none of the 2007 heavy duty trucks had DPF's. With smaller diesel pickups like Dodge had early 2007 year model Rams with the 5.9L Cummins (produced from June '06 up until Dec '06 - no DPF) and then production switched over with the 2007.5 year model Rams with DPF equipped 6.7L Cummins. It was all a big financial windfall for oil companies, the government collecting fuel taxes, and shops working on untested technology in the name of "saving the world". It made anyone who didn't drive trucks feel warm and fuzzy. Prior to all of the meddling 2002 electronic engines were at the peak of efficiency. It's taken them this long to get past that but even so shops still make money off emmissions problems and a whole new industry was created to sell overpriced DEF.

 

My 04 Star does not have an EGR. Its an MBE 4000. I ordred it in Oct of 03. By Jan of 04 they were out of nonEGR motors in the Mercedes.

 

Well that pretty funny

 

in many cases motors dont get put in trucks right away. An 04 with an older motor could easily be non egr.

 

Wasn't it because of the cycle beating in the emission test, by Detroit Diesel, Volvo, Mack Cummins, and maybe a few others, that the 04 emissions limits were pulled forward and put in force in 02 for the "cheaters".

I think Mercedes was not considered one of the "cheaters", and were allowed to sell the non-egr engines untill 04.

Maybe that was the reason to call the engine Mercedes MBE4000, and not Detroit Diesel Series 55???

Just my thoughts, I may be completely wrong.

 

In some cases pre-emission trucks were built on a "pre-buy" order and stockpiled without being put into service. They would then be put in service at a later date, and would be titled at that time. So you could see a pre-emission '02 truck titled as an '03. That's been more common in recent years when the EPA has changed the rules considering all the past problems.

My carrier did a large pre-buy on '09 trucks before the emission changes for 2010 (DEF) went into effect. That kept them issuing trucks with just the DPF filter and no DEF well into the middle of 2010... those trucks built in '09 were all titled as 2010 trucks.

 

The Mercedes 4000, and 906 were alowed to be polution back dated for a period of time, because they were new to the market.
Please do not tell me anything about the Acert, being problem free, I worked on them. exhaust inserts breaking destroying both turbo's, intake valve actuators, and Cat would try and get you to do 10 hours of work and pay 4 hours. Water pumps.
Just a thought!

 

They started with mbns on 03 model year trucks.

 

I never said that they were problem free. I said that they have less problems. All the EPA 04 Detroit's we've had had at least 1 turbo, several EGR valves and several EGR coolers, VPODS replaced, the list goes on. Very few made it over 700,000 without an inframe due to the cylinders being polished like a mirror and using oil, some just over 500,000 when the warranty just ran out. We only have 1 CM870 Cummins and that got a turbo, 2 EGR valves and 1 EGR cooler so far.

The Acerts have injector harness issues, actuator issues, rocker studs break, ect. But, we are over 900,000 on most of them without pulling heads or throwing big money at them. Ours are all MXS and NXS 475 HP engines, with all the "upgrades" done. We have not had many issues since we replaced the rocker studs and put on the new actuator housings.

Acerts definitely have there issues, but compared to EGR Detroits and Cummins, we're getting much lower cost per mile with the Acerts.
