API CK-4? When? & what's different from CJ-4?

[djten4]

Just had a meeting with maxum and was told about the API CK-4 which is in the works to replace the API CJ-4 from 2006 to now. Does anyone know about this?

here are the required specs for API CJ-4: http://www.apicj-4.org/performance_specs.html

Have the specs for CK-4 been released. What are the benefits? (i'm assuming it is better for emissions and DPF, EGR, DOC, etc...) I would love to see an updated list of the required ASTM bench test scores. i.e. sulfated ash, sulfur, phos., anything else that may have changed, or become harder to meet.

Thanks guys, i'm sure someone on this website knows something about this!

I believe the upcoming HDEO specs will have lower HTHS (below 3.5; like 3.1 or 2.9) for better fuel economy. They will NOT be backwards compatible for older engines.

Scheduled for release in 2016. Global emissions specs met with EGR, DPF, SCR with Urea injection.
It also called "PC-11". PC-11 HT/HS 2.9, xW-30 will be OEM dependent, not backward compatible.
New tests:
CAT C13 Aeration control
Volvo T13 Oxidation control to prevent copper lead bearing corrosion
Daimler DD13 Scuffing test, and other tests still under development.

That would be correct. The primary purpose of the new classification is for economy. This is because of the 2014 mandate on heavy commercial diesels to exhibit a 20% improvement in fuel economy. The government has just about tweaked the emissions requirements to death, so now they are moving towards CAFE standards for heavy commercial trucks. All current production heavy commercial trucks have EGR, DPF, SCR now. That standard in place with 2010 EPA standards. Now it is primarily about economy.

However, when spec'd right and operated right, a pre-emission heavy commercial truck will get better fuel mileage than even the 2014 standards dictate. My 2000 Detroit Series 60 is getting 25% better mpg than the average fleet standard. The 2014 government standard calls for 20% improvement. I am already ahead of the game with an engine that isn't saddled down with all the other junk and is over a decade older. Sure it is "dirtier" according to the EPA. But it has also been shown that the fast food industry, by grilling burgers, emits more environmentally destructive components than commercial trucks. I would have to drive 143 miles to emit the same particulates and other matter out of my semi truck engine, as it takes to grill 1 hamburger.

As indicated in the above posting: all reason and common sense have been thrown out the window when it comes to over-regulation.

If the (soon-to-be bankrupted) State of CA could differentiate between the water vapor that comes out of a tailpipe vs. regular ol' H2O vapor (the number 1 so-called "greenhouse gas" by a mile!) they would set a standard and try to regulate it!
