addition of a single component part, the yoke-arm.


New Technology for Piston Engines

Big-Step Engine Technology™

Yoke-Arm Technology Substantially
Advances Engine Performance
Finding important break-thru energy innovations to save fuel and money should be one of America’s top priorities. To date, the engine and auto industries have exhausted most avenues to improve the piston engine and little or no consideration has been given to the piston-rod mechanical linkage. Big-Step is a “leap frog” initiative by Fisher Technologies to move forward with a proven, patented linkage and modern-day break-thru for the piston-rod/crankshaft connection substantially improving the performance of conventional piston engines.

Both automobile manufacturers and engine designers historically have been mostly of the mind-set to design and develop “small-step” improvements, and such a mind-set has slowed the progress for discovering the much greater break-thru needed today. Piston engine improvements should be top priority for the American public who now have the opportunity to contribute and help advance the implementation of a new and innovative change needed today. Fisher Technologies has discovered a revolutionary break-thru which provides the necessary changes for all piston engine types including aircraft piston engines, but additional funding is required to prevent the interruption of development for a technology which should affect everyone soon with proper funding. Important funding is needed now to accelerate development instead of waiting the usual 3-6 year interval for completion.

Donations are wanted so that funding will not be the main cause to slow down a revolutionary change that will affect and change people's lives in a positive and substantial way. Our privatized development team wants to accelerate development.

To learn more about an innovative and progressive technology which can improve all our lives, review our website (ref. summary below) and see for yourself just how relatively simple changes for conventional engines provide substantial benefits for everyone. Benefits like 2-3 times present-day fuel economies that result in more than 100 mpg for smaller vehicles and 50 mpg or more for much larger vehicles. Greater fuel economies for diesel engines are especially realized because the slower burning diesel fuels become even more efficient than gasoline because of the increased piston dwell during combustion. Other benefits affecting all piston engines are significant power increases and much fewer emissions because of the substantial increases in combustion efficiencies provided by the added piston dwell. Donations to maintain the development for such a progressive technology are very important and most welcomed. Once you have reviewed our website you will have seen an animation of just how all this works, and will also find out how you can donate to maintain and perhaps accelerate our development and implementation.

Thank you for your consideration.

Simplicity of the Yoke-Arm for Such
Large Performance Benefits
Fisher Technologies has developed a modern-day performance increase for all piston engines which dramatically improves the efficiency for conventional engines, both gasoline and diesel. This unique cutting edge technology provides substantial increases in fuel economy, significant reductions in exhaust emissions and more power just by adding a "yoke-arm" between the piston rod and power-shaft. A simple mechanical combination, never before developed for piston engines, uses a unique yoke-arm linkage that connects the piston rod to the crankshaft, yet leaves the remaining mechanical arrangement for conventional piston engines relatively unchanged.

This new arrangement uses a unique yoke-arm which substantially increases piston dwell during combustion to significantly increase combustion efficiencies. Surprisingly, this simple modification not only provides large gains in combustion efficiencies, but also greatly decreases piston rod angularity and the associated piston friction. The result is superior fuel economy, increased power and reduced emissions for both conventional crankshaft powered gasoline and diesel engines. Most all conventional engines can be accommodated such as single-cylinder, V-type, in-line, horizontally-opposed and radial with no restrictions to engine size or application.

The low cost and simplicity to implement the Fisher yoke-arm surprisingly translates to large performance benefits for both piston engines and compressors. As it turns out, piston driven air compressors and air conditioners also become a viable application with significant increases in mechanical efficiencies that require much less power. This new technology offers an easy approach to substantially increase engine performance and fuel economy while also reducing the engine size through increased power. Diesel engines will especially gain a large advantage because the slower burning diesel fuels derive great benefit from the added piston dwell during combustion. Such large increases in piston dwell are not possible with conventional engines or the many other experimental engine technologies you might have read about. The Fisher yoke-arm technology for piston engines has finally achieved the much needed combustion efficiencies with the necessary simplicity, low cost and superior performance that so many other attempts using mechanical arrangements have failed to do.

 

Summary of Benefits
The essence of this advancement is the dramatic increase in combustion and mechanical efficiencies just by using a simple modification for the piston rod/crankshaft linkage. It is well known that fuel savings occur at slower speeds and lower engine rpm which correlate to increased piston dwell. The added dwell provided by the yoke-arm makes the engine think it is running at a slower speed. Increased piston dwell provides this "virtual" slower speed advantage, but without the loss in power associated with conventional engines running at reduced speeds and lower rpm. The fuel savings made possible by the Fisher yoke-arm might be compared to the effects of a “super” overdrive for automobiles during highway driving. Of course, such a super overdrive with the same fuel savings and power as Fisher does not exist in today’s transmissions. However, those familiar with the benefits of overdrive might consider that the Fisher Technology in combination with the transmission overdrives used today, will realize increases in fuel economies and savings that will be quite astonishing. Also, the substantial power gains and significant reductions in exhaust emissions will be a great addition to the substantial fuel economies.

The Problem
The Automobile Industry and the many other various engine manufacturers need improved engine performance in keeping up with the necessary changes to protect our wallets and environment. Both the Automotive and Engine Industries are now struggling to comply with Government requirements and are falling behind in keeping up with proposed future regulations and Government mandates that will provide the necessary advancements to protect us and the Earth’s environment. The Automotive Industry has requested that the US Government reduce the fuel economy and emission requirements for future vehicles because, by their own admission, they do not have the technology to meet such fuel economy and pollution mandates for the forseeable future. Fisher's yoke-arm has changed all of this.

The Solution
The yoke-arm “linkage” offers a solution to the Automotive Industry and piston engine manufacturers by providing the necessary advancement to help us all keep up with the much needed improvements required to protect the Earth's environment. Those that have influence within the automotive, trucking, marine, aircraft, or motorcycle industries, and especially the diesel engine industry, can email us relevant contact names, suggestions and/or comments to help us implement this technology. A technology that saves an enormous amount of fuel while helping to protect our Planet. Relevant contacts within the Departments of Energy and Transportation, the EPA or other environmental groups will help us advance this much needed technology. Please email your suggested and relevant contacts.

Continued Development Required
Ongoing development for the Fisher Yoke-Arm will be necessary to ensure that this innovative and creative solution can be transferred or “handed over” to the automotive and engine manufacturers this year or next. When this occurs, much less development by engine manufacturers will be required because most of the preliminary design work has been completed and should “jump start” these important industries into production. The yoke-arm linkage advancement will help the Automotive Industry because their focus and priorities have been on other means to improve fuel economy and emissions. The yoke-arm linkage for vehicles and worldwide engine applications will provide dramatic energy savings while helping to conserve a most important and limited natural resource, petroleum.

A first prototype was constructed which produced very encouraging dyno test results. Fisher Technologies and is currently constructing a second and larger prototype to obtain additional data to support what dyno testing and computer modeling has already shown to be a very viable advancement. Our R&D has been ongoing for some time to find ways to substantially improve the performance of the piston engine which has resulted in the yoke-arm linkage design. However, additional funding is required to ensure that our ongoing development will not be stopped, and important funding through continued contributions will greatly help ensure the completion of timely development and quicker implementation for the Vehicle Industry.
