Will Split-Cycle Engine Compete With EV Powertrains?
One cylinder of Scuderi's split-cycle engine performs intake and compression, while the other handles power and exhaust. The engine completes all four strokes in one crankshaft revolution. (Figure courtesy of Scuderi Group.)
Hello to all. Scuderiengine.com answers many of your questions. THIS innovative engine technology will definitely shange the engine world (ICE) forever. Lets NOT be "Car-Centric" here. There are ICE Internal Combustion Engines in many other applications and not only the automobile. Lawnmowers, tractors, big generators, boat engines (large + small) basicly ANY ICE with piston technology. As a former Rubber+ Plastics engineer and a youthful "Motor-head",,,, I knew this project was a winner within 30 minutes of a complete inspection of their technologies and developments...
Go to the web-site. This concept "ATDC" is not only central but its been their focus for many years; at Team Scudei. I immediately invested upon being offered the opportunity to get on board with this "Gamechanger" ..
In my opinion....look at the progress and then the depth and gameplan that Scuderi employs. They are asked...they answer beyond expectations and then they engineer beyond expectations. Right now...at 65 mpg proven via simulation,,,there is talk in the 80 mpg range and a longer view of 100 mpg. Will they breach these barriers? I do not know; but they have repeatedly pushed foward beyond their expectations many times before.
Right now....I await the announcement of our 1st leassee of the technology and I am preparing for the push to "Go Public " as Sal Scuderi has stated may times in the past; as the GOAL of Scuderi Motors. The time has come for a real world demonstration. The significant strides foward can no-longer be kept in the closet. It's time to show the public and get ready for the stampede !!!!
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?
If a major catastrophe strikes your area, will you be prepared? Do you know how to modify the tech you've already got or MacGyver what you need to fit your own situation? A free, five-day Continuing Education Center course starting April 6 will show you how.
