Probably the boldest ACERT innovation is variable intake-valve actuation, and its electronic controls. Cat employs a solenoid adapted from HEUI which allows the on-board computer to work with the camshaft. Refinements to MEUI enable it to inject varying amounts of fuel several times during each compression stroke.
What is an ACERT engine?
ACERT is an assemblage of reasonably familiar componentry that might appear unspectacular compared to the attention this technology has garnered. The C7 and C9 ACERT engines retain hydraulically actuated electronic unit injectors (HEUI), used on Cat mid-range engines since 1997.

If tuned correctly, the C15 ACERT can be a strong, reliable engine. There are some problems with earlier models however, which we'll go over. At the beginning of production a common issue was broken rocker studs. This shouldn't be a problem anymore, because by now most ACERTs have updated studs.
Does a CAT Acert have an EGR?
In contrast to 2002/2004 engines from other manufacturers, the ACERT technology did not utilize cooled EGR for NOx control. Instead, it relied on an advanced proprietary combination of in-cylinder NOx control techniques, possibly including elements of partial HCCI combustion and internal EGR.

what is an ACERT Cat? are they good engines? I don't want or have one but im curious of whats the difference between a normal CAT and an ACERT is
Gear head Medium Load Member
acert is advanced emmisions reduction technoligy. It means that they have intake valve actuators that open the valves under pulls to help clean up exhaust output. They are good engines the only problem is the intake valve actuators go up sometimes but they are easy to change.

I've been running one for almost 200k and it's been ok. The only emission related problems I've had has been a sensor that's went bad three times, but it is a five minute job to replace it so it's not too bad.

What is the difference between a computer adaptive test and a paper-and-pencil test?
The obvious difference is one is taken on a computer and the other isn’t. (Care to take a guess which one is the computer exam?)
How Does CAT work?
Computer adaptive testing works by measuring your competency with each question asked.
How Does the Computer Determine Passing or Failing?
Whether you pass or fail the NCLEX is determined by one of the following three rules:
