Flipping filters
One of the most noticeable changes for the new X15 is the change
from canister style to cartridge filters for both fuel and engine oil.
" With steel canister filters, when you need to change oil, you take it
off and throw the whole thing in the trash, " Marsh explained. " Also,
when you drop the filter off the engine it's full of hot oil and very
heavy. It's not a great solution for the environment or for the person
servicing it. The new design is a reusable plastic housing with a media
that you change as a cartridge by pulling it out of the top. "
Engineers added a drain to aid the serviceability of the filter. " You just
put a hose on there, spin the housing cover loose, the oil drains out and
then you just drop the filter off the engine. It's much simpler to service
when it's lighter, and you're only throwing away the media, " Marsh said.
" We're doing the exact same thing on the fuel filter side as well. We
chose not to do a top load design because as you service them, any debris
that's on the top can get caught where the filter goes. We wanted to
be able to drop the whole thing off and clean it before reassembly. "
Forward thinking
With the latest X15, Cummins has exhausted a lot of resources and
engineering hours to produce a powertrain that still meets customer
expectations while also satisfying the looming North American

There is a critical challenge to advancing vehicle technology: optimizing hydrogen
connection systems for performance and safety. This 30-minute webinar will
address the difficulties engineers face with traditional clamping ring systems used in
hydrogen applications and will present a superior solution that improves assembly
behavior and safety. The program will focus on an advanced system that offers a
more efficient and reliable alternative.

The new X15 features pistons
with a revised bowl to improve
combustion efficiency. The centerline of the
pin has also been moved closer to the firing deck.
regulations that go into effect in 2027.
" A lot of what we've been trying to do is improve overall
CO2 performance and make the engine lighter, while
at the same time maintain the robustness of the product
while adopting the global platform, " Marsh said.
Holcomb added, " The importance of the latest X15
is that we're meeting those new NOx regulations but
still offering improved fuel economy and similar DEF
consumption. "
