Attention Gear Heads - A totally new engine design

Have you guys seen this yet?
a new engine design with applications possible from Big Trucks to Cars, Motorcycles, ect......
I think that it's pretty cool!



A really good Demo Video:

.The OPOC has been in development for several years, and the company claims it’s 30 percent lighter, one quarter the size and
achieves 50 percent better fuel economy than a conventional turbo diesel engine.
They’re predicting 100 MPG in a conventional car!

Perhaps not toally new, but significantly different from its predecessor. The company where I was an apprentice (in it's military aircraft branch - now BAE) was called English Electric. In the 1950 - 1970 timeframe they had a railway locomotivre division. They made a locomotive called "Deltic", becuse of its engine configuration. During my apprenticeship, I had about 3 months in the engine build shop. I got one ride on a break-in run of a new loco - spectacular acceleration without a train on behind!

Each "slice" of the engine had three double-ended cylinders in an equilateral triangle. There was a combustion chamber at each corner of the triangle and a crankshaft in the middle of each side. The two pistons came together at the combustion chamber, giving a higher compression ratio than a sngle cylinder. The three crankshafts were geared together to a common final drive.

The complete engine could be assembled in modules, each containning a "slice", but the production engines were either 12 or 16 slices, I think, and were about 6000 horsepower. The Deltic loco had two engines. British Rail found out, after the Deltic went into service, that one engine was sufficient for normal running, up to about 120 mph, so the procedure was to have them both running for the start-out from a station stop, then shut one of them off when cruise speed was reached. It was re-started as the train approached the next stop.

The "popular history" was that someone dropped a "pi" in the calculations and the engines were actually 3-times more powerful than they expected. This was long before all the modern electronic control of turbos and injection systems we have these days. They locos served fo many years, eventually phased out as main inter-city lines were converted to electric proulsion, with 60KV overhead catenary wiring. The Deltics were too powerful and had too high a fuel consumption to be used on local trains. I believe a couple of examples survive and are on restored "enthusiast" railways in the UK.

Yip, its still on the same page
