TENSION
AND THE
ELECTRIC
TAKEOVER
The average age of
vehicles in the U.S.
continues to rise -
complicating the role
of automakers and
suppliers charged with
assuring adequate
supply of replacement
parts even as they
hasten the move away
from legacy propulsion.
because they have the least amount of portability into
EV world, " Mark Wakefield, global co-leader of consultancy
AlixPartners' automotive and industrial practice,
told Reuters in October 2022.
" We have jumping to an entirely new architecture,
we have a rapid acceleration in the supplier [transition]
required and we have an incredible restriction on
the source material, the critical materials, " observed
Ohio State's Atkinson. " So, how that's all going to pan
out is just not at all clear. "
" If in 2030 we're in the 30% range [for EV sales in
the U.S.], I think that that would be a home run for this
industry towards electrification, " said Standyne's
Pinson. " And I think it's going to take everything the
industry has got to get there. In the meantime, we
have these overriding objectives to get carbon out of
the transportation sector. "
At Stanadyne, as with most other suppliers, IC enThe

100% EV by 2040, etc. The specifics, however are a bit less detailed.
For the coming decade of propulsion transition, suppliers are at
the tip of the spear. They, as much as OEMs, will be burdened with
the unenviable task of balancing the industrial ledgers. And for now,
most agree, that will mean a careful and steady management of internal-combustion
investments - even though many in the industry
are prone to an accelerated view of the EV takeover. " Engine parts
makers are ground zero for the most amount of pain in this transition
26 December 2022
gine-technology development continues The company
is developing a new generation of high-pressure, gasoline
direct-injection (GDI) fuel-injectors. They're designed
to operate at 500 bar (7252 psi) and 1000 bar
(14,504 psi), ultra-high pressure that Pinson said will
provide significant efficiency gains and emissions reductions.
Stanadyne also intends to introduce electric
GDI fuel pumps that enable total decoupling from the
engine, reducing parasitic losses.
Schaeffler Group, while transitioning its business to
electrification, nonetheless has a litany of new components
and systems aimed at improving ICE efficiency
and power. It's new " e-rocker " electromechanical variable
valve-timing system eliminates hydraulics and
improves response time and other engine performance
and NVH parameters.
