The temperature of air rises, when compressed, because of the increased friction of the air molecules brought about by their reduced volume and increased density. The compressor side of the Scuderi engine will compress the air and, under compression, transfer that air to the power cylinder. Because the compression ratio remains constant, when transferred, the temperature of the air also remains constant and fuel ignition is successful.

When, however, that compressed air is transferred into a compressed air tank, which has a far different volume, it becomes very difficult for me to envision the mechanics by which the compression ratio can be maintained. Without this high compression, there can be no doubt that the air temperature will be reduced; this makes me wonder how this air can be used in a diesel engine.

When I interviewed Mr. Scuderi he assured me that this issue had been addressed and further stated that the air pressures developed by the Scuderi design were much higher than those seen in any previously designed diesel engine. You should listen to the interview.

I know, you have probably figured out that I am a dentist, not a trucker. I was looking at the scuderi stuff because I was interested in Air/Gas or Diesel hybrids. Charging an air tank with power returned via decompression through a piston or turbine engine like a dental slow speed handpiece (piston) or a dental high speed handpiece(turbine) to assist in propelling the vehicle like a hybrid Prius but with a reverse engine rather than a battery and electric motor. The Scuderi has the capapbility to utilize this system and has a built in compressor. Some of their illustrations show this “extra tank” over the two working pistons and a valve off the compressed air side manifold(what do you call some of this stuff). This tank could also receive compressed air from “braking energy recovery.”

Like I said, I know that I am not a trucker, but the mechanics intrigued me. Picture a BMW Motorcycle in 4-cylinder diesel boxer engine configuration sipping soy-bean oil. Who knows??

I’m not going to change my skeptical interest in the thing to enthusiastic interest until they build a prototype that performs on a near equal level to the virtual (computer) testing that’s been performed. My opinion of computer analysis (i.e. global warming) is that it’s one step above “totally useless” in providing real world data.

If indeed I get the opportunity to interview the CEO I’ll pursue this line of questioning. Thanks for taking the time to look at this, Everitt.

Apologies in advance please….my initial impressions are disturbing.

First off…their use of hybrid and my understanding of it’s use are different. The Scuderi is an ICE.. (internal combustion engine)…even if it does have an integral piston supercharger…and it supplies rotational energy….a hybrid in general usage is a combination of two (or more) energy formsICE-electric, ICE-Hydraulic…electric-hydraulic…..etc.

Second….. this appears to me to be very similar to a two-stroke engine. A mechanically supercharged two stroke perhaps? Or “An integraly supercharged two stroke” since the supercharger is part of the engine instead of being a bolt on.

And this is not a BAD thing. Nothing wrong with two strokes and a whole lot GOOD about them. But why hide it?

Like I said…I’m no mechanic…not by any stretch. There’s every chance I’m wrong.

Third thing….the faint odor of scam.

If this is so good…build it…and dispell that odor.

I’m a truck driver. I get lied too daily. Hourly sometimes. By engineers even.

“What?…It’s can’t be that HEAVY! It only weighs….yadda yadda…” I’m hypersensitive to lies….you might call me a cynic.

Build it Now.

A prototype built with a large number of “off the shelf” parts can’t be all THAT expensive. Then put it in a truck…give it to me…and I’ll test it for ‘em.

Like Tuco Benedicto Pacifico Juan Maria Ramirez said in that Great American Sphagetti Western….” The Good, the Bad and The Ugly”…..http://www.youtube.com/watch?v=VUslGSoEH8I

“When you have to shoot…shoot…don’t talk”

If the Scuderi is so good…or even half as good…as they claim….

………”build it and they will come.”
