Default Shockwave-Generating Wave Discs Could Replace Internal Combustion Engines




Quote:
Michigan researchers have built a prototype of a new auto motor that does away with pistons, crankshafts and valves, replacing the old internal combustion engine with a disc-shaped shock wave generator. It could slash the weight of hybrid cars and reduce auto emissions by 90 percent.

The generator is about the size of a saucepot, and would replace the 1,000-pound power train in most cars — no transmission, cooling system, emissions regulation or fluids needed. Norbert Müller and colleagues at Michigan State University showed off the new motor prototype at a meeting with the Department of Energy’s Advanced Research Projects Agency.

It consists of a rotor carved with wave-like channels. Fuel and air enter through central inlets, and the rotor spins to block their exit through a separate outlet. The sudden build-up of pressure generates a shock wave, compressing the mixture. Then it’s ignited, and as the rotor keeps spinning, the outlet opens again to let the hot gases escape. New Scientist explains in further detail.

The novel generator would use about 60 percent of fuel for propulsion, according to MSU. This is a dramatic improvement over typical car engines, which use only 15 percent of fuel for forward movement. The system could also make cars 20 percent lighter, improving fuel economy even more.
MSU received a $2.5 million ARPA-E grant to develop the technology. Müller said he hopes to have an even larger 25-kilowatt prototype by the end of this year.

this probably has less torque than a rotary. would be interesting to see what the plan is, use this to generate electricity, and then use electric motors to power the wheels?

Riiiiight. I will believe it when I see it. This reeks of one of those engines works on a CFD model. Let me see it in real life and I may believe it. If it is too good to be true, then it probably is.

Sounds like a rotary gimmick, and 1,000lbs? LMAO!

His next invention on the market will be nuclear-fusion powered impulse drive.

His anti-matter warp core is still in prototyping.

Just from the article it doesn't look like something that would be direct drive, but a decent power source for an electric car needing additional range.

Isn't this almost like the concept of antilag on a turbo, except that the cold side wheel is removed and replaced with a torque shaft and used to power a gearbox/generator?

Read teh article. It's for an electric generator.
