New Car Engine Sends Shock Waves Through Auto Industry
Discovery News ^ | Apr 6, 2011 | Nic Halverson

Posted on 05/21/2011 2:18:29 PM PDT by Windflier

Despite shifting into higher gear within the consumer's green conscience, hybrid vehicles are still tethered to the gas pump via a fuel-thirsty 100-year-old invention: the internal combustion engine.

However, researchers at Michigan State University have built a prototype gasoline engine that requires no transmission, crankshaft, pistons, valves, fuel compression, cooling systems or fluids. Their so-called Wave Disk Generator could greatly improve the efficiency of gas-electric hybrid automobiles and potentially decrease auto emissions up to 90 percent when compared with conventional combustion engines.

The engine has a rotor that's equipped with wave-like channels that trap and mix oxygen and fuel as the rotor spins. These central inlets are blocked off, building pressure within the chamber, causing a shock wave that ignites the compressed air and fuel to transmit energy.

Continuing from the article:

"The Wave Disk Generator uses 60 percent of its fuel for propulsion; standard car engines use just 15 percent. As a result, the generator is 3.5 times more fuel efficient than typical combustion engines.

Researchers estimate the new model could shave almost 1,000 pounds off a car's weight currently taken up by conventional engine systems.

sounds good, but stuff like this disappears

and never makes it to market.

So it’s like a diesel engine (no spark plugs) and a turbo somehow combined.

I’d like to see a working model.

We'll see. This thing has a whole lot of sunshine on it. Sorta hard to suppress it out of existence, when millions are reading and talking about it.

Did you also notice that these folks have a $2.5 million dollar grant from the Advanced Research Projects Agency to develop this engine?

$2.5 million in funding

If they can take $2.5 million and increase efficiency from 15% to 60% that will be the best investment in the history of the world.

Similar concept to a turbine engine and much cheaper to make probably. If they can produce it cheap then this is huge.

My neighbor has a Mazda RX-8 and approximately once a month I see a rollback truck comes and picks it up, and after a few days (of apparent shop work) it brings it back. Must be a real bow-wow!

Let's hope it is better than one. There is a reason you don't see 70's and 80's RX7's around.

IMHO Nothing wrong with the modern combustion engine if ya remove the EPA mandated drag anchors errrr pollution control errr.... accessories.

X-Prize an affordable 2 seat commuter ride with nerf like qualities run flat tires and 300hp to the rear wheels that gets 100mpg. Don’t forget a Sat Sirrus / XM FM radio with bluetooth and GPS !

Oh an a bubba mug holder !

Resale value says they are. Nice looking cars, very fast. I haven’t driven any of recent vintage but the original RX-7 was a blast, very linear, hummed right up to redline and felt as if it could have kept on going. No wild thrashing, almost turbine-like.

But, they use something like a quart of oil every 2,000 miles as a matter of course, it was in the owner’s manual. They also suck gas like a semi. I suspect all the autopilot American owners and drivers are being too casual about checking and changing the oil in the things, among other bad habits. The Wankel engine is not forgiving of that. Kaboom.

In terms of sealing, particularly corner sealing, pretty much the exact same problems.

Perhaps better materials and new manufacturing techniques will overcome the problems this time.

My thought exactly. I knew a fellow where I worked who bought one of those Wankel-engined Mazdas, and we used to have a lot of fun at his expense when it refused to start on really cold mornings.

I would guess it wouldn't have much torque as it isn't spinning much of a flywheel. Could be good for a generator but not for direct power.

It is for a generator. They plan to use it in plug-in hybrids. It will run at a constant speed at it's most efficient RPM.

Fuel is just part of the total cost of ownership. Doesn't matter how fuel-efficient it is if it needs tuneup/repair every week, or if it needs replacing after 25K miles. I would want more reliability figures before wanting to buy it.

If I were the developer, I would put a few dozen on the road as taxis or other high-mileage commercial vehicle. Get 50K-100K miles on it in a year or so, see the reliability figures, and THEN market it (and yes, a NYC taxi would get that kind of mileage in a year or two -- a medallion taxi often gets driven round the clock by shifts of drivers)

The major component of both designs require a centrifugal fan. The big difference is the angle of the combustion fan blades by adjesting them to near 90 degrees.

The major obstacles of this design would be the design of the engine block, ignition timing and exhaust elimination. The concept looks cool.

I'm not really qualified to say, but it looks to me like there are some real differences in the two motors.

I also don't think the developers would have gotten a $2.5 million dollar grant from the Advanced Research Projects Agency to copy and paste an existing ICE technology.

I remember reading an article about the Wankle when Mazda first put it in a car. They said the mileage was slightly worse and it wasn’t quite a clean but experts say it is the ideal power plant for a car.

I said - ok then.
