How the Scuderi Air Hybrid Engine works

An1MuS Says:

Jul 2, 2009 - But maybe the compression of the air that'll go into the next piston makes up for that unproductivity.

Jul 12, 2009 - hey hey hey man. were all friends here. no need to caps lock at me.

Jul 23, 2009 - its just a fancy supercharger.

Jul 24, 2009 - Fancy indeed. Using the compressed air in the combustion process directly is a huge advantage over other hybrid systems, which for example just air-motor.

Aug 10, 2009 - Try touching an air compressor after 5 mins of operation. Its really not "cool" after all

Bloodcurling Says:

Aug 10, 2009 - I don't think its worth it, just seems like too big of a loss for it to be effective

Aug 12, 2009 - It's a massive increase in size, weight, complexity, and cost for a tiny increase in efficiency.

mastersduhgree Says:

Aug 12, 2009 - Right.And you would think if it were revolutionary than it would be used in recent machines.

Aug 13, 2009 - might as well call it a 2 stroke or even better a 3 stroke lol

Aug 14, 2009 - There are many hundreds of patents over the last 50 years, with all sorts of ingenious ways to improve the standard internal combustion engine. How many have made it in widespread use? I don't know of any, excepting ancilliary devices, such as catalytic converters, alternators, fuel injection, etc. Sad, but true. Maybe the Miller Cycle could be one case, but made only by Mazda, and then dropped. The Scuderi engine will have a very uphill battle.

Aug 18, 2009 - fancy 2 stroke

lavid2006 Says:

Aug 23, 2009 - simple too...but how does it control the air to fuel mixture? Is it fuel injected or carbureted or what?

GILBERTORACE Says:

Aug 25, 2009 - why not buying a turbocharger w/ air to air intercooler it will work the same in your 4 stroke engine it will be more efficient and less expensive its just the same system bye more complicated :S since i don,t like to travel at 65mph in the free way :S

russ13b Says:

Aug 26, 2009 - would have to be fuel injection, don't think a carb would manage with these different modes and suddenly having more intake pressure etc. Now that i've told you that, can you tell me how it's throttled please,,,,

russ13b Says:

Aug 26, 2009 - as boiling water has 4x the expansion rate of burnign fuel, why not get the old 6 stroke engine working?

lavid2006 Says:

Aug 26, 2009 - do you already know the answer or do you want me to tell you? Im not 100% sure but to accelerate the valve letting more air into the powder cylinder, and the fuel injector would have to increase simultaneously. That would be my guess. To slow down simply slow the rate of fuel being pushed into the power cylinder.

Fox111one111eleven1 Says:

Sep 15, 2009 - Only 40% effeciency? Well it's about time someone stepped up to the plate and kicked the Jumo 204's ass. So all the money that's going into this won't be going into more effecient drivetrains, lighter chassis, and more aerodynamic bodies? Guess we're still stuck driving our overweight, gear driven, drag chutes down the highway. Seriously, is a continuous bellypan and ducted airflow for cooling too much to ask for?

Oct 8, 2009 - Two years later and...?

SWATsqad Says:

Oct 12, 2009 - its 4 stroke

physiist777 Says:

Oct 22, 2009 - 6-cycle? interesting....

mongrelchild Says:

Nov 4, 2009 - ahh the old binary cycle studied in every thermodynamics textbook. This is a very interesting implementation.

shukiikuhs Says:

Nov 16, 2009 - But you see, most gasoline engines are 10-20% efficiency. Most of the energy is converted to heat, and very little to motion.

zamzungas Says:

Nov 19, 2009 - its split cycle
