Even with the many advancements evident on today’s internal combustion engines…the basic premise is pretty much the same. A four-stroke setup delivers air and fuel , getting one “power” stroke out of every four. It’s not exactly efficient, though there are many ideas on how to improve the process. Scuderi Engines has developed a design utilizing compressed air and a unique four-stroke setup.
Normally, a four-stroke engine goes through 2 up and 2 down cycles; intake, compression, power, exhaust. Of these four strokes just one, the power stroke, puts any energy to the wheels, and each cylinder is responsible for its own four-stroke cycle.
The Scuderi engine breaks the four stroke cycle up between two cylinders. The cylinders are paired together, with one cylinder handling intake and compression and the second cylinder handling power and exhaust. The Scuderi engine also fires just after top dead center on the power stroke, giving the piston more leverage over the crankshaft.
That isn’t the only fuel-saving feature on this engine though. A compressed air tank can recapture air during braking procedures, and use that air to help propel the vehicle forward much more efficiently. Add on a turbocharger, and Scuderi reports a 35% improvement in fuel consumptiuon, boosting MPG’s by over 50% in tests.
What’s more, this little engine is quiet. Just watch the video below if you don’t believe me.
So just how serious is this engine? Currently
11 automakers 19 automakers have signed non-disclosure agreements while looking ways to implement this technology into their own vehicles. Scuderi has done a computer simulation using as a test vehicle a Nissan Sentra using the EPA MPG measuring system, conducted by an independent lab. There is no working, road-going example of this engine…yet.
But Scuderi conducted another computer simulation measuring its performance compared to Europe’s top fuel economy performers. The simulation estimated that the Scuderi engine could return an average of 65 mpg, compared to 52 mpg that many fuel-frugal Euro cars get (which we assume is on the U.S. testing cycle.)
Some say we’ve reached the peak of ICE engine efficiency, but I would beg to differ. Creative ideas like the Scuderi engine could usher in an age of ultra-efficient engines at a time when gas prices seem destined to climb ever higher.
