The Kamtech OBE core technology has long history.
The concept of moving pistons with a cam rather than a crank has a long history. One of the first aircraft engines to be certified for flight by the United States Navy was a radial cam engine, the Caminez engine developed by the Fairchild Group of Companies. Yes, the same innovative guy who founded Fairchild Semiconductor, which developed the first computer chip in the late 1950s and spawned California's Silicon Valley. This forward-thinking entrepreneur was positive that the Radial Cam engine was the future of IC engines and spent years developing it. But in 1927, there was a large problem he could not overcome. The milling machines were manual and were simply not able to machine close-tolerance cams, and this prevented the refinement of the concept. Today, Computer Numerical Control or CNC machining has solved that problem. The proof is found in our highly efficient Rad Cam engine.
The visionary who kept saying "It can be done!"
In 1982 Professor Antoni K. Oppenheim, of the University of California coauthored an SAE paper with J. Douglas Dale, of the University of Alberta entitled "A Rationale for Advances in the Technology of IC Engines, (SAE #820047) The underlying message of the paper was that the 1861 Otto cycle engine had reached it peak of dedevelopment and it was time for industry or society to develop an engine that had higher thermal efficiency. Professor Oppenheim later published the books "The Dynamics of Combustion" and "Combustion in Piston Engines". His vision of an ideal IC engine would be a direct-injected two-stroke engine with port positions so that a significant portion of the previous charge was retained. He explained that such an IC engine could transform far more of the heat of combustion into work than the ubiquitous Otto cycle engine. However, the industry had billions of dollars invested in the Otto Cycle engine and was content with add-on technologies like computer controls and catalytic converters, which he called "band-aid" fixes. Antoni was always on the lookout for someone to take up the challenge to develop a more ideal internal combustion engine.
Toni's vision of the Ideal engine finds a designer.
Reading a patent is like brainstorming with some of the most creative minds in the world. The best patents define their innovation in simple, understandable terms, so if needed, the innovations can be defended in front of non-technical judges or jurors. In 1991, at the West Coast Patent Library, Jim first came across the patents on Fairchild's Caminez radial cam engine. This led him to his long association and friendship with Professor Antoni Oppenheim, who urged him to take on his challenge to develop a more ideal IC engine. Pursuing this goal has been a long adventure. It has led Jim to also seek help from Smokey Yunick, who explained why a constant acceleration cam was the best option, as shown in the third image to the left. Over the years, there has become a long list of other people, institutions, and companies in many parts of the world that have contributed their technical skills and ideas to the project..
Jim has long been an advocate of conserving energy, and in the 1970s, he designed and built several energy-saving passive and active solar buildings that saved from 50 to 80% on their energy cost. The first such building was sponsored by the Johns Manville Company. He later spent four years on the speaker's bureau of what became the Illinois Environmental Protection Agency, giving technical lectures at universities, community groups, and companies on methods and benefits to society of saving energy. It was a job offer by a solar company that brought him to California in 1981.
Why Kamtech's OBE the best energy source for EVs!
Kamtech's OBE, or On Board Energy unit, is a small, self-contained electric power plant. It can be tuned to meet US and European emissions regulations. Unlike the energy source for virtually all EVs. namely, the "deadliest energy in the world," the world's electric grid, it does not emit toxic or poisonous gases, only CO2 and water, which are the foundation molecules for all life on earth. CO2 is an organic molecule.
The OBE operates only when needed and runs at its most efficient speed and load. It only generates electric power to charge the EV's batteries or, if needed, drive accessories and the electric drive train. Being "on board" rather than far away the system does not suffer up to 20% distribution, transformer or charging losses as is the case with all EVs that are plugged into the world's electric grid. The Kamtech OBE replaces up to 80% of the EV's batteries. This allows your EVs to be far more efficient, to stop faster, and to handle better. The Rad Cam was developed to give clean, highly efficient power, and the perfect balance of its Rad Cam power plant makes it run as smoothly as your EV's electric motors. The Rad Cam's first licensee was a small aircraft company. Aircraft engines normally operate at around 80% power capacity, and aircraft engines must be robust and efficient.
The Kamtech OBE unit can be sized to the application
- Weight: 40 to 50kg (without fluids)
- Compact Design (50 cm diameter x 50 cm tall)
- If service is needed, it can be quickly unplugged and removed, and replaced in as little as 20 minutes.
- Its low cost allows for leasing to remove the car buyer's fear of reliability.
The Kamtech OBE also has sufficient power to operate an air-conditioning compressor via an output shaft with minimal impact on range.
The true efficiency that sets Kamtech OBE apart was developed under the mentorship of the team's three consultants, Professor Antoni K. Oppenheim, Smokey Yunick, and Professor Huynh Thanh Cong, and the details were worked out through long brainstorming sessions between Jim Duncalf and Phạm Duy Tùng here in Vietnam.
The Pre Vietnam Team players
Professor Antoni K Oppenheim
Luminary Of Rad Cam
Antoni was like the father of this project. He was determined not to let us fail in this challenge he gave us. When things looked insurmountable Toni would open up one of his large file cabinets and in a few minutes would find an answer. Then with the patience of a teacher, he would break down solutions or new concepts into understandable words. He never once said he did not have time to examine our progress. He was determined not to let us fail in this challenge he gave us. He always showed great enthusiasm for developing answers on how to improve the efficiency and performance of the Rad Cam engine concept. He was never short of new and innovative ideas. With quiet modesty, he was happy when we proved his concepts were viable. He is sadly missed.
Smokey Yunick
Mechanical Consultant
Smokey Yunick, was one of the most creative and knowledgeable engine designers perhaps in the world. He did consulting for various automakers during his years, most notably Hudson, Ford, and General Motors. Duncalf contacted him in 1991 shortly after taking on Professor Oppenheim's challenge to develop a truly "ideal engine." A few days after Duncalf explained Oppenheim's thoughts on better piston dynamics Smokey called with a recommended a constant acceleration cam profile. He explained that such a dynamic would put the least initial force on the engine and produce the longest dwell time at both ends of the stroke. His insights into lubrication were also helpful. He too never put a time limit on his contributions. Duncalf went into this project partly because he had long been a fan of Smokey's articles in Popular Science magazine.
Jim Duncalf
CTO and Patent holder
Jim is the guy who took on the challenge to lead the efforts to fulfill Professor Oppenheim's vision of an "Ideal Engine". His zeal for this project was inherited from father. In 1923 Jim's father electrified his parent's farm. The power came from a converted windmill connected to a bank of discarded railroad signal batteries. It was very popular in the area. Then in 1935, the police destroyed the system. A legal monopoly was given to the wealthy owner of a local power company. In many countries, large electric power companies are now seeking a similar legal monopoly to provide electric power to all the world's cars. In the last couple of decades some of the richest people in the world art trying to get a legal monopoly to sell electricity to the world's cars. But today a rising backlash is about to happen. Please resist!
Mark Beierle
Engine designer/builder
Mark Beierly, the head of design and major stockholder of Earthstar Aircraft Company, was our first licensee. Mark and his team built several generations of prototypes, the last one being a production version. Every one of the prototype engines gave clear proof that Professor Oppenheim's writing in several papers and books regarding combustion dynamics were valid. When Duncalf, Yunick, and Beierle turned Oppenheim's concepts into a working design the engine's thermal efficiency was very close to 50%. Beierle efforts, skill, and experience in engine design and his dedication to the building and testing of the engine were key in making the Rad Cam a practical and efficient power plant that will revolutionize the EV sector.

After thoughts of the development process
R&D is not for the faint of heart.
Every new technology goes through three phases: concept, development, and commercialization. In the case of automotive engines, its concept and patent happened in 1861 by Alphonse Beau de Rochas, its commercialization happened 27 years later with the sale of the first “Benz Patent-Motorwagen" in 1888. This has not been a full-time job, even for the patent holder, and many of the contributors were renowned academicians whose enormous innovations are seldom rewarded. The production plans for our first licensee came just as the US and the world entered the Global Financial Crisis.
The Rad Cam engine is the future of On Board Energy
In the case of the Rad Cam engine, it was first fully conceived in the fall of 1991 at a meeting between retired UC Berkeley Professor Antoni (Toni) K Oppenheim and Donald James (Jim) Duncalf. Although the need for a radical replacement of the basic 1861 is much older. It took thirteen years of problem-solving, redesign, building, and testing before Earthstart’s production version clearly demonstrated the efficiency advantage of the radial cam concept over the standard 4-stroke engine. We've lost track of the number of changes. Development of the Rad Cam engine has been a long and expensive process, as there were hundreds of little issues that had to be addressed and solved before we found the way that worked. The last two problems that brought the project to Vietnam have finally been solved, but we had to design, build, and test hundreds of ways that did not work before we found the ways that did..
