Yoke-Arm Technology Substantially
Advances Engine Performance
Fisher Technologies has developed a modern day engine that provides dramatic improvements in the performance of both gasoline and diesel engines. This unique and cutting edge technology provides substantial increases in fuel economy, significant reductions in exhaust emissions and more power all just by changing the linkage between the piston rod and power-shaft. A simple mechanical combination, never before developed for piston engine applications, uses a unique “yoke-arm” that connects the piston rod to the crankshaft, yet leaves the mechanical arrangement for conventional piston engines relatively unchanged. This new arrangement, patent protected, uses a yoke-arm to substantially increase piston dwell during combustion considerably increasing combustion and fuel efficiencies. Surprisingly, this simple modification not only provides large increases in combustion efficiencies, but also significantly decreases piston rod angularity and piston friction. The result is superior fuel economy and increased power with reduced emissions for conventional crankshaft powered gasoline and diesel engines. Most all conventional engines can be accommodated such as the 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 also become a viable application with significant increases in mechanical efficiencies. 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 engine applications will especially gain a large advantage because the slower burning diesel fuels derive great benefits 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 and low cost that so many other attempted 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 relatively simple modification for the piston rod/crankshaft linkage. It is well known that fuel savings occur at slower speeds or lower engine rpm which correlates to increased piston dwell. Such added dwell 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 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 are quite astonishing. Also, the significant power gains and substantial reductions in exhaust emissions are a great addition to the superior fuel economies.

The Problem
The Automobile Industry and the many other various engine manufacturers are lagging behind in keeping up with the necessary requirements to protect our 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 changes 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 distant future. Fisher's yoke-arm has changed all of this.

The Solution
The yoke-arm “linkage” offers a solution to the Automotive Industry and all piston engine manufacturers by providing the necessary breakthrough to help 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 us your suggested and relevant contacts.

Continued Development Required
Our ongoing development for the Fisher's 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 soon. When this occurs, there will be much less development required because most of the preliminary design work has been completed which should “jump start” these important industries into production. The yoke-arm linkage advancement will help the Automotive Industry since their focus and priorities have been on other means to improve fuel economy and emissions. The yoke-arm linkage technology for vehicles and worldwide engine applications will provide dramatic energy savings while helping to conserve a most important and limited natural resource, petroleum.

Fisher Technologies has produced a first prototype and is currently constructing a second and larger prototype to obtain additional data to support what computer modeling has shown to be a viable breakthrough. 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 implementation for the Vehicle Industry.
