Startup Working to Commercialize Direct Injection Ethanol Boosting + Turbocharging
25 October 2006

Ethanol boost with turbocharging promises a cost-effective means to obtain high fuel efficiency in gasoline and flex ethanol/gasoline powered engines. MIT scientists and engineers earlier this year founded a company—Ethanol Boosting Systems, LLC (EBS)—to commercialize their work on direct-injection ethanol boosting combined with aggressive turbocharging in a gasoline engine. (Earlier post.) The result is a gasoline engine with the fuel efficiency of current hybrids or turbodiesels—up to 30% better than a conventional gasoline engine—but at lower cost.


EBS has a collaborative R&D agreement with Ford, and anticipates engine tests in 2007 with subsequent licensing to Ford and other automakers. If all goes as expected, vehicles with the new engine could be on the road by 2011.

The engine would operate with a wide range of ethanol consumption from a minimum of less than 5% up to 100%.

The combined changes could increase the power of a given-sized engine by more than a factor of two. But rather than seeking higher vehicle performance, the MIT researchers cut their engine size in half. Using well-established computer models, they determined that their small, turbocharged, high-compression-ratio engine will provide the same peak power as the full-scale SI version but will be 20 to 30% more fuel efficient.

The ethanol-boosted engine could provide efficiency gains comparable to those of today’s hybrid engine systems for less extra investment: about $1,000 as opposed to $3,000 to $5,000. The engine should use less than five gallons of ethanol for every 100 gallons of gasoline, so drivers would need to fill their ethanol tank only every one to three months. The ethanol used could be E85.

1. Aquygen™ Hybrid Hydrogen Car

Product: Aquygen™ Gas

Imagine cutting steel or running a car with ordinary water.

Aquygen™ is a novel gas made from ordinary water through our patented electrolysis process. It replaces oxyacetylene for most welding and cutting applications with superior efficiency, quality, cost-effectiveness, and safety without the need to replace existing equipment. An Aquygen™ flame in open air burns at only 259° F, but applied to a substrate it can produce temperatures of over 10,000° F depending on the target media. Aquygen's unique properties also make it an ideal additive for fossil and other fuels, increasing BTUs while decreasing emissions. It even works for a hybrid hydrogen-powered car.

Under direct inspection, Aquygen™ Gas proves to be odorless, colorless and lighter than air. It has a number of unique features that distinguish it from water vapor and the Brown gas produced by standard electrolysis.

In the production of Aquygen™ Gas, there is no evaporation process at all, the electric energy used being insufficient for evaporation. This feature alone establishes that the H2O Model 1500 Aquygen™ Gas Generator produces a new form of water that is gaseous and combustible.

2. "Gaseous and combustible" water

:eyes:

Now all this website needs is a link to a zero-point or perpetual-motion energy source to round things out.

3. There is nothing perpetual about their system

Nothing magical about water converted to hydrogen via electrolysis and burned by an engine. This is old technology and has been done before. The major drawbacks are corrosion from water if the engine sits too long (remedied with gasoline) and wasted energy from the electrolysis process.

Now, if they claimed it can run close looped or create more energy, it would be a perpetual machine.

4. Water is not combustible

One of it's constituents, hydrogen, is, but water itself is not. That alone makes me question the scientific knowledge of the people who wrote it.

"Nothing magical about water converted to hydrogen via electrolysis and burned by an engine. This is old technology and has been done before."

Exactly, we've known about generating hydrogen from water through electrolysis for many decades. So, why is this so revolutionary? Why the need to include such erroneous phrases such as "gaseous and combustible" water?

5. getting back to reality 101 - here is a link to an MIT site that goes into some detail on the direct

injection ethanol boosted engine. In case you don't recognize the initials MIT they stand for the Massachusets Institute of Technology, a fairly well thought of university known for excellence in various technical areas of research.

Ethanol having a considerably higher octane than gasoline enables you to use a higher compression ratio in your engine design or through the use of compression of the air fuel mixture fed into the combustion chambers (through the use of turbo or super-charging). thus the BTU discrepancy between gasoline and ethanol is a non issue. It's just a matter of using an engine that takes advantage of the superior characteristics of ethanol. With turbo charging come much higher power output which can be used for reduced fuel consumption (by using a smaller engine, for example).

Here is an excerpt from a document produced by the MIT Plasma Science and Fusion Center,
Mechanical Engineering Dept. and Sloan Automotive Laboratory

Ethanol biofuel could play an important role in meeting these goals by enabling a
substantial increase in the efficiency of gasoline engines. In this paper, we discuss an
ethanol boosted engine concept where a relatively small amount ethanol is used to
increase the efficiency of use of a much larger amount of gasoline by approximately
30%. Gasoline consumption and the corresponding CO2 emissions would thereby be
reduced by 25%. In combination with the additional reduction that results from the
substitution of ethanol for gasoline as a fuel, the overall reduction in gasoline
consumption and CO2 emissions is greater than 30%. This approach involves only modest
changes to the present gasoline engine systems and fueling infrastructure. The increase in
vehicle cost could be modest (approximately $600). This leveraged use of ethanol could
substantially increase its energy value and help to alleviate concerns about a low energy
output/ input ratio (energy provided by the ethanol/energy need to produce the ethanol).

Direct Injection (DI) Ethanol Boosting

A substantial increase in gasoline engine efficiency can potentially be achieved by use of
a strongly turbocharged small engine to match the performance of a much larger engine.
The aggressive turbocharging (or supercharging) provides increased boosting of naturally
aspirated cylinder pressure. The engine thus produces increased torque and power when
needed1. This downsized engine at the loads used in typical urban driving has a higher
efficiency due to its low friction while providing the maximum torque and power
capability of a much larger engine. Engine efficiency can also be increased by use of
higher compression ratio.
