Mechanical Engineering start-over!

    Declaration of Need To Improve World Life Style, and Environment, Through Better Energy Management!

    In relation to the energy field, current technology is leading us into stagnation! Today, piston engine technology is available that will effectively renovate the machine age. Society is conditioned to accept mediocrity by its concern for peak performance instead of efficiency. For us to advance as a society it appears we have to take one step back, and apply technology with the progressive facts that will propel us into a future with less greenhouse emissions, noise pollution, inflation, while improving public safety.

    The scope of this announcement is much larger than 'the uninformed' will generally admit. Demand for the insistence of continuing glut by the general public needs to be abated! Academia wants to increase sophistication and complexity by hybrid vehicles, whereas their concept is too early if applied onto engines who's mechanical technology is more than 80 years past their peak of design (and should be scrapped)!

    Now building hybrids using Fisher engines for 200 mile per gallon ideology should occur after about 20 years or so after the improved machine age commences - inspired by the Fisher Brothers!

    If this spikes your curiosity, please check out the lecture components that I am preparing for the Metaphysical group in Garland Texas. This happens to be my current engineering project and I am consulting with Pat Fisher. The Fisher Brothers now wish to gain notoriety for their 2005 patent.

    Reinventing the Machine Age

    In the modern world, the rush toward more sophistication sometimes encourages emotionalism to overrule wisdom and logic. Academia and institutions seems to encourage scatterbrain thinking, where what novel projects which appear to be breakthroughs; thereby encouraging effort into less productive, more expensive and complex venues. The open projects discarded then take almost superhuman effort to reinstate because of the status quo opinion passed onto high ranking authoritarians. This entanglement of knowledge over wisdom seems to be a pervading weakness with the academia's over educated fraternity.
    [Note: Over educated means knowledge that overwhelms rather than assists a project]

    75 years ago Russel Bourke came up with a very effective engine design that was quite remarkable. It was forced into the 'sophistication loop' to compete with the state of art four cycle engines that had prominence in that period of time. This simple engine is still outperforming the current (high tech) “modern” state of art engines, but was blackballed at the time because of high wear, and resistance to change? Reviewing Bourke's technology with our modern world materials we uncover the fact the high wear experienced is now non existent! Bourke's concept becomes even more effective with a mechanical engineer's approach of interweaving his patented cam technology to improve effective dwell time of the loaded piston up to 250%! This means more power for less fuel induction, for considerably better fuel efficiency for a given engine displacement. Patrick T. Fisher is the inventor (and holder of the Fisher engine patent) that uses a yoke on a pivot to create a cam action on the piston to extend its Top Dead Center and Bottom Dead Center dwell. Broadening the high pressure dwell gives many advantages like a complete burn for creating minimal greenhouse gases, making ignition timing uncritical (so a computer controlled timing advance system becomes obsolete); low exhaust back-pressure simplifies noise reduction (with appropriate small muffler), eliminating an aircraft's need for intense acoustic insulation (for example). Modulating the form of the yoke itself to proscribe an arch, finesses the piston dwell via subtle cam articulation to reach the surprising 250% effective dwell increase mentioned above - that is also controlled by the trailing arm length to pivot, which also improves transfer piston combustion pressure by reducing connecting rod angularity, for totally improved mechanics over the conventional “modern” engine. Bourke was right all along with his original claim that we are building engines WRONG!

    Interesting characteristics of the Fisher engine are:
    1. High torque at low rpm. In motorcycle and automobile applications this means transmissions of fewer gears are needed.
    2. Lower back-pressure for a cooler exhaust means smaller mufflers and catalytic converters.
    3. Lighter engines that have improved rpm regulation for aircraft - making variable pitch props more effective.
    4. Coupled piston supercharger makes the engine work up to 60,000 feet MSL. [Replacing the jet engines in a 727, you would have an aircraft that would fly from America to Germany, and back to America without refueling! And still cruise at 500 mph - smooth and quiet!] 2 stroke diesel simplicity and reliability, with jet fuel the fuel of choice.
    5. Supercharged options for the Fisher piston engines are inexpensive to produce, and service. Rotary engines like the Wankel, Atkinson etc. require expensive centrifugal superchargers; and these engines cannot be scaled up to power large ocean vessels; like the Queen Mary (with its 8 foot stroke pistons). The rotary designs are definitely not noted for fuel economy.
    6. Because the Fisher is stingy with fuel, due to an extremely lean burn, the smaller lighter Fisher engine is a natural for emergency power generators.
    7. Marine applications gain because of great torque at lower rpm, and less critical timing.
    8. Small bikes and scooters will travel more than a hundred miles on less than a gallon of fuel; while needing only 2 gears to be quite peppy.
    9. Power tools will be more effective because of better torque with less fuel storage.
    10. This is the needed engine for ultra lights!

    The wear factor is a non existent concern, meaning the Fisher designs life will equal, or exceed that of a conventional engine in operational hours - with future overhaul being inexpensive and simple because the prime wear components are in the removable cylinder, piston, and head. Obviously we have a Win Win situation here.

    The biggest hurtle to overcome is the thought of retooling. Too many years have past doing engine design wrong! So it will take the public and Government together to overcome oligarchy resistance. Obviously the benefits are extreme with higher performance vehicles sipping on a lot less fuel. Smaller less expensive 'catalytic' converters although not necessary, most likely will be insisted upon - following attitudes of being difficult for our Government to let go of that control, would be lasting considerably longer.

    Today, there is a thrust for the hybrid automobile, with high technology a guiding light. In engineering terms, this attempt is quite “foolish!” This would excessively, and unnecessarily, complicate the automobile by having two propulsion systems that require computers to interface them with complex programs (with corresponding updates); all done with a basic fact that it would not compete in performance, or economy, with the simpler Fisher design, that is the better scavenger of energy. To move a vehicle takes energy whether it is stored electrical, or chemical. Two systems that are serially linked by computers, is 4 times less reliable compared to one basic simple, high efficiency system.
    [Serial linkage: The mechanical engine has to run to charge the battery. The battery discharges through the electrical motor to aid the mechanical engine's torque. Add the fact that the fuel weight must include battery weight (that also reduces carrying capacity volume )!]
    The bottom line is that the Fisher engine would be considerably less expensive to implement and maintain.

    Lets go further with the Fisher concept, like the Fisher pump! Air conditioning systems require a compressor pump. Instead of the regular rapid compression piston pump, lets replace it with the longer dwell Fisher, and what do we gain? The longer dwell yields better temperature dissipation of the pressurized gas at the compressor pump, with improved diversion efficiency to improve heat dissipation at the condenser coils that is attempting to liquefy the gas. The longer dwell improves the one-way valve's time constants, improving the pressure transfer exhaust. The liquid that lost the bulk of its compression temperature traveling through the condenser coils, is now feeding the evaporator coils that permit the liquid to convert back to gas, expanding and thus dropping temperature. The Fisher pump would be a small price to pay to improve thermal and mechanical efficiency from less piston friction.
