Rotoblock (OTCBB:ROTB) Inspires Innovation for the 100-Year-Old Internal Combustion Engine

SANTA ROSA, Calif.--May 15 2008 --For the past 100 years there has been relatively little innovation in the Internal Combustion Engine (ICE), but with gas prices at record highs and the economy squeezing average Americans, engine developer Rotoblock, Inc. (OTCBB: ROTB.OB) has a new innovation called the Oscillating Piston Engine (OPE).

Not since Ernest Godwin developed his Economizer in 1908 have experts recognized any remarkable innovation in Internal Combustion Engine (ICE) technology. Online encyclopedia Wikipedia lists the year 1908 as the last milestone in their overview on the history of the ICE.
With gas-electric hybrids quickly becoming the fastest-selling cars in America, the future of the ICE seems uncertain. Some major automakers are even predicting in the future all their models may be hybrid or electric. While the days of the ICE seemed to be numbered, Rotoblock, a small startup in Northern California, still believes in pistons.
Rotoblock has patented what is called the Oscillating Piston Engine, which they believe can increase the power-to-weight ratio by up to four times that of today's ICE. What's more, they are researching other drive train and power delivery technologies that may increase the efficiency of thousands of today's consumer products exponentially. The Company has attracted an ambitious new management team led by a Chinese-American entrepreneur who is exploring new business opportunities in China that can bring the Oscillating Piston Engine and other technologies to world markets.


An Oscillating Piston Engine (OPE), unlike the standard ICE, incorporates four pairs of pistons. Each piston is a segmented toroidal section traveling within the closed toroidal chamber of a rotating cylinder block. The combustion chamber is formed between each pair of pistons and as they rotate these pistons oppose each other creating a four-cycle interaction of combustion and exhaust. The repetition of these four combustion cycles produces sixteen power strokes for each revolution of the cylinder block.

What this could mean for the average user of a gas engine is that, with a Rotoblock OPE, fill-ups could be once a month instead of every week.
