A New Energy Conversion Principle with Potential to Double the Efficiency of Today's Engines

Teacher Naitoh of Waseda University's Faculty of Science as well as Engineering has discovered a brand new compressive combustion principle that may yield engines with the greatest level of efficiency. With a energy efficiency of 60% or more within applications including automobiles, energy generation, and aircraft, will certainly their low fuel usage be superior to that of HV vehicles?

Professor Ken Naitoh of Waseda University's Teachers of Science and Anatomist (Department of Applied Technicians and Aerospace Engineering, College of Fundamental Science and also Engineering) and his associates have found a revolutionary energy conversion theory (new compressive combustion principle) able to yield stand-alone motors with double or higher the actual thermal efficiency potential associated with conventional engines, independent of the size. If engines making use of this principle can be put to include in practical applications, it is considered that they could become improvements with the ability to solve today's instant environmental energy problems.

The brand new compressive combustion principle had been formulated by Professor Naitoh through the development of a new thermofluid dynamics theory, as well as believed experiments, supercomputer simulations, along with high-speed airflow experiments working with that theory. The fundamental rule is that while thermal effectiveness can be raised by achieving a high compression ratio, accomplished through pulsed collisions regarding multiple high-speed jets of the air-fuel gas mixture in microscopic regions in the main area of a combustion slot provided, expanded uses and varies of application were achieved with the further addition of three new measures. This method can also be considered to be lower in cost compared to batteries, as well as having opportunities for noise reduction and also the potential to eliminate the need for air conditioning mechanisms.

If the effectiveness of the principle can be confirmed via combustion tests, it will not just open up the doors to brand new lightweight, high-performance aerospace automobiles, but would also result in prospects of next-generation, high-end engines for automobiles. The utmost thermal efficiency of present-day gasoline engines for cars is on the order of 30%, considered to fall to a level as little as 15% in states through idling to low-speed town driving. Therefore , if motor vehicles could be equipped with "low-cost, ultimate-efficiency engines, " reaching the stand-alone thermal efficiency involving 60% or higher over a broad variety of driving conditions, it is thought that a substantial fuel intake superior to that of current mixed system automobiles could be a fact. Furthermore, if such vehicles, equipped with these high-efficiency machines, could be used to generate strength at individual households, it might open up possibilities for enhancing the total energy efficiency of our own entire society (The pictures above are of main prototype engines produced to verify the new principle, at the beginning of ignition testing).

These research effects were announced in research documents at events including the springtime congress of the Society connected with Automotive Engineers of The japanese (JSAE), held in May 2013, and the conference of the United states Institute of Aeronautics in addition to Astronautics (AIAA), held in North park in June 2013, along with journals and magazines upon science and technology.
