This joins a long list of
innovative engine designs that have been worked on over the years. They all have specific advantages that make
them attractive to continue development, yet usually run into the limitations imposed
by materials. That is why we still use
the same engine geometry developed a century ago.
This one looks attractive and
looks to be naturally light. One hopes
it makes it into the market.

MSU researchers create a new engine prototype (w/ video)

(PhysOrg.com) -- Researchers at Michigan State University have built a
prototype, based on the research first released in 2009, of the Wave Disk
Generator -- an engine that does not have pistons, crankshafts or valves.
This new
model, which does away with the internal combustion engine of the past, has the
potential to reduce auto emissions up to 90 percent, when compared to the
current emissions level. This is because the engine uses roughly 60 percent of
its fuel for propulsion, when you compare this to the typical cars engine that
uses only 15 percent of fuel for propulsion, we can see how the increase is
possible.
The new engine prototype is built with a disc-shaped shock wave
generator that is about the size of a sauce pan, and will require no
transmission system, cooling system, emissions regulation or fluids, which
means that you will end up not only doing something good for the planet, but
you will end up with less in maintenance costs, if this new prototype ever
comes to the market.
The engine works like this: a rotor, with a wave-like pattern carved
into channels. The fuel and air enter and mix through the central inlets. The
rotor then spins, blocking the exit of gasses. As the pressure builds it will
generate a shock wave that will compress the mixture. Once it is ignited an
outlet opens to let the hot gases escape, and your car can move as usual.
The engine prototype was shown off by Norbert Müller and other
colleagues at Michigan
State University
at a meeting with the Department of Energy’s Advanced Research Projects Agency.
