Hello Tom.
No, quoting:HCCI is a low temperature combustion technology utilizing
compression
ignition of well-mixed air-fuel mixture.Unlike the conventional diesel
engine,
HCCI emits ultra low emissions of NOx and PM. On the negative side,
it can produce increased HC and CO emissions.
This is a diesel engine, no doubt. The Sterling engine works with external
combustion and takes advantage of the expansion (not combustion) of the
working gas (hydrogen, helium, or air).

Hi all,
Are these HCCI engines related to the Sterling engine I've just starting
to
learn about?

Study predicts growth of HCCI engines
A new study analyzing trends in heavy-duty vehicle powertrain
technologies by 2020 has been released by TIAX, a collaborative
product and technology development firm, and Global Insight, an
industry forecasting firm. One of the findings of the study is a
predicted growth in homogeneous charge compression ignition (HCCI)
engine technology which will be displacing conventional heavy-duty
diesel engines. The study also predicts greater use of heavy-duty
hybrid vehicles.
The study, titled The Future of Heavy-Duty Powertrains, was
commissioned by a group of oil companies, engine and vehicle
manufacturers, and component suppliers to investigate the impact of
more stringent emissions regulations, increased traffic congestion,
and a shortage of skilled drivers for large vehicles on the
heavy-duty vehicle industry in North America, Europe, and Japan.
Key findings of the report include:
- HCCI engines will power nearly 40% of heavy-duty vehicles by 2020.
Initially HCCI will only be able to power light loads at low speeds
so early versions of the engine will also incorporate conventional
diesel combustion to supply more power when greater demand is placed
on the engine. A full mode HCCI engine will eventually supersede the
mixed mode HCCI/diesel technology.
- By 2020, 15-25% of heavy-duty vehicles globally will incorporate
either hybrid electric or hydraulic hybrid technology. The rapid
deployment of hybrid technology in the heavy-duty vehicle industry
will be driven by savings on fuel and brake maintenance by vehicle
operators.
- The demand for self-shifting transmission technology in heavy- duty
vehicles will increase dramatically over the next 15 years. The
self-shifting transmissions can maximize fuel efficiency and to
broaden the labor pool from which drivers can be recruited because
trucks with automated or automatic transmissions are easier to drive.
HCCI is a low temperature combustion technology utilizing compression
ignition of well-mixed air-fuel mixture. The major technical
challenge in HCCI is the control of combustion, with most of today's
engine prototypes being able to sustain the HCCI combustion mode only
at low to medium engine loads. Unlike the conventional diesel engine,
HCCI emits ultra low emissions of NOx and PM. On the negative side,
it can produce increased HC and CO emissions.
The predicted growth in HCCI engines is particularly significant in
that the exhaust gas aftertreatment systems currently being
developed- -targeting mostly NOx and PM emissions--and expected to
reach the market in the next few years will start to become obsolete
by 2020. Instead, HCCI emission aftertreatment would need to target
HC and CO emissions at very low exhaust temperatures.
