The Wankel is still being produced in small numbers. It is good for
being compact, but is still hard to keep sealed and less efficient
than piston types. You could run one from a gasifier, but I wouldn't
bother if I had a piston engine available. We've already lost the
"compact" description.

There is a similar looking engine in the Science museum in London,
which was removed from a WW 2 German Aircraft. It was a high
compression Diesel.
Being flat, it fitted into the wing improving the Luft flow thus
increasing the furrshluggerindurger.
However, I seem to remember another innovative "Hardly any moving
parts engine" called the Wankel which was heralded as being
extremely wondrous,
Whatever happened to it's final development? and would it run on a
gasifier product?

The Fairbanks Morse OP engines that propelled the WWII subs were
that design. There are still a few cogen plants around today that
use those engines as well in dual fuel configuration, but they were
supercharged, not turbocharged.

Hi Pete
Eco motor is innovative modern IC engine evolution
You can see video , animated pictuures too
http://www.ecomotors.com/
The opoc® engine comprises two opposing cylinders per module, with
a crankshaft between them -- each cylinder has two pistons moving
in opposite directions. This innovative design configuration
eliminates the cylinder-head and valve-train components of
conventional engines, offering an efficient, compact and simple
core engine structure. The result is an engine family that is
lighter, more efficient and economical, with lower exhaust emissions.
EcoMotors' opoc® engine has a number of distinct advantages over
traditional internal combustion engines. The opoc® engine has very
high power density of nearly one horsepower per pound resulting in
an unprecedented lightweight and compact engine. The opoc® engine
is perfectly balanced enabling stackable power modules. This unique
modular displacement capability is one of the long standing, but
elusive goals of engine engineers' quest for high efficiency. In
addition, it also results in much less NVH than a conventional
engine of comparable power. Its elegantly simple design allows for
low cost, efficient manufacturing and increased operating durability:
50 percent fewer parts than a conventional engine
Straightforward assembly
No cylinder heads or valve-train
Uses conventional components, materials and processes
"Consistent with our leadership strategy, Navistar continues to
seek innovative products which differentiate us from the
marketplace, while others embrace the status quo," said Eric Tech,
president, Navistar Engine Group.
Power Density
The internal combustion piston engine has been the primary means of
automotive propulsion for more than a century. Today, thousands of
engineers around the world are hard at work trying to improve this
19th century invention. Some are striving to make incremental
gains; some are hoping for a breakthrough. For all of them, one
measuring stick is the "acid test" for any engine -- power density.
As greater power density is achieved, a range of critically
important attributes will result, including:
Lower weight
Smaller size
Lower material costs
Lower friction
Greater fuel efficiency
Lower emissions
Lower heat rejection
Electrically Controlled Turbocharger
EcoMotors' intellectual property also includes an electrically
controlled turbocharger technology which incorporates an electric
motor in the turbo assembly to regulate boost pressure resulting in
a long list of unique advantages:
Improved combustion efficiency to meet emissions
Electrically controlled variable compression ratio
Improved vehicle fuel economy
Enhanced vehicle drivability due to improved low-end torque
Eliminates Turbo lag
Waste heat recovery by generating electricity
