This is likely to be what gets the automakers to the 54 mpg 2025 limit. If automakers are foreward thinking enough, they can trumpet they got there 10 years early, too.
Still, this takes away from the goal of weaning off fossil fuels. The innovation that DOES make a storage battery approach the power density of liquid fuels is what is needed.
This sounds a lot like our two stroke engine, except for being more complicated and having six valves. Clearly it allows much more variation in timing of all the several parameters like when to start the air intake portion and when to inject the fuel. Depending on the timing requirements, the same functions could possibly be delivered by a standard two-stroke engine, even better if it had direct fuel injection. Such an engine might possibly also fare better in emissions testing, although efficiency and low emissions seldom peak at the same time. But as the split stroke is compared to a two stroke, it is clear that they are similar.
Seems to me that any kind of technology that has the potential to advance the cause of fuel efficiency is to be taken seriously. Glad to hear that analyst groups and automotive OEMs have this on their radar screens even if it's some time out before we see the actual technology in production vehicles.
I think this is going to be a good technology to watch. With the government mandating higher fuel efficiencies and "good enough" battery technology still a few years away, this might be the technology that gets us there.
Proving this works in high output engines will be an important factor. It does have some interesting characteristics, for one, the hot side of the engine stays hot and the cool side does not heat up too much. This is in contrast to the Otto cycle characteristics.
I would be very curious as to just why the retardation of the spark helps so much in this design compared to the Otto cycle. And another obvious question to me is if the split cycle is amenable to creating a split Diesel cycle? Would there be any benefits in that?
By refining topologies and using new fluid technology, Moog's new peak sine drive controller increases available power without increasing controller volume.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
