Rotoblock Advanced Engine Technology on Display at NADA 2008 in San Francisco


SAN FRANCISCO--Feb 6,2008 Advanced engine developer Rotoblock (OTCBB:ROTB - News) will display its patented Oscillating Piston Engine (OPE) technology at NADA 2008, February 9-12, at San Francisco's Moscone Center, the largest convention for auto dealers in North America.ADVERTISEMENT Rotoblock's patented OPE engine technology uses the principle of rotating opposing pistons in a rotary-style engine that reduces the weight and size of the engine while increasing the output. The engine represents advantages in power-to-weight ratio as well as energy efficiency being sought for fossil fueled vehicles.

Rotoblock Chief Executive Officer Mr. Chien Chih Liu will be on hand at NADA to discuss the most recent developments for the Oscillating Piston Engine. He is also scheduling meetings to collaborate on future development and implementation of the OPE with prospective partners.
The US produces approximately 35 million small engines annually that are sold and used in the US alone. These numbers do not include engines used as power sources in automobiles, aircraft, construction equipment, recreational vehicles, stationary applications and more. They also do not include small engines used outside the country.

The problems with standard small engines include: an inefficient weight to power ratio; cumbersome water cooling system which can lead to rust; complex friction movement causing frequent wear and tear; expensive and time consuming maintenance; not being adaptable to a variety of uses; and the release of a high percentage of toxic and carcinogenic emissions causing environmental damage.

Based on Rotoblock's experience as well as careful calculations and preliminary testing, the OPE was found to: be dramatically lighter, up to 50 percent depending on the application; significantly increase the power to weight ratio; be simpler to assemble, maintain and repair; require no valves and valve train; not require a water cooling system; and be adaptable to a wide variety of sizes and uses. In addition, because of its rotating intake/output design, the Rotoblock OPE releases significantly reduced emissions into the atmosphere even with regular fuels. The OPE is also highly adaptable for use with blended fuels or hydrogen which increases its environmental efficacy.
