Scuderi: Split-cycle engine will soon be licensed

by Jeremy Korzeniewski (RSS feed) on Apr 18th 2008 at 8:02AM

The Scuderi split-cycle engine technology is not new to our pages. Last year around this time, we had an opportunity to interview Nick Scuderi about the company and came away thinking that the idea, though unproven, has some merit. According to an article on Automotive News, Scuderi is confident that they will line up some licensing agreements to use their technology shortly. Apparently, some amount of validation has been completed recently which offered promising results.

Diesel Scuderi engines could post 30 to 50 percent lower nitrous oxide emissions according to the company and gasoline/compressed-air hybrids are also in development. Still, real test-engines are not yet up and running, so there is a long way to go before anybody will know for sure if this engine design is able to meet its expectations. Watch a video after the break of a simulated rendering of the Scuderi engine in action.

I wonder just how much more effiecient it is running off the air tank since it still has to move the compression cylinder.

Leviat, when the engine is running on stored air, the valves would remain open on the compression cylinder to eliminate drag. There is no expectation to maintain compressed air levels in the storage tank when using it as a power source. The tank would be re-pressurized when the engine is running in combustion mode and could even use the compression stroke for braking/slowing, as well.

Seems like the frictional losses will be the real challenge to overcome with this design, or any new engine design. I'm always a little skeptical of fancy promotional videos showcasing a nice computer model of revolutionary new technology that hasn't been tested yet. Granted, it could work quite well, and I'll be very impressed, but I'll believe it when a real engine is in a dyno cell putting out real numbers.

Ingenious design; I just wish it didn't require twice the cylinder count (more weight, more space) than a conventional engine. The air-hybrid version, though, is an interesting possibility compared to electric hybrids.

It doesn't require twice the cylinder count. With a standard 4 cylinder engine each of the 4 cylinders fires with every two revolutions of the crank. With the Split cycle design 4 cylinder the two firing cylinders fire with each revolution. So with 2 revolutions of a conventional engine you'd get 4 fires. with 2 revolutions of the split cycle you'd also have the same 4 fires since the 2 cylinders will have fired twice.

I just read a same article in GreenBizSite.

As for the space/weight argument, they are predicting somewhere in the neighborhood of 130-140hp per liter. That said, a 2L 4cyl scuderi could possibly put out between 260-280hp... without all the added weight of the batteries required by a petrol/electric hybrid. Additional tanks to store pressurized-air may add weight, but not as much as the batteries and are much more environment friendly when it comes time for disposal. Made of carbon-fiber, the storage tanks would be safer in a collision too.
