HP2g 110mpg Hybrid Engine Patent Issued !

[Frank Lee]

I didn't look at the patent either; I saw the lil picture.

No meat here. Just meat flavoring.

Sorta like, "where's the beef?" ?

Not meat flavoring, so much as meat by-products.

Just as a f'rinstance, like a not-too-exotic N45 neodymium, the critical temp is...what?

[looks up "Curie temperature"]

Okay, never mind. Inside the engine is hot, but not THAT hot.

It's more complicated than that. Things like "temperature coefficient of coercivity" that the electrical engineer in the next office understood far better than I did. Which is why he chose samarium cobalt magnets for use in a liquid cooled electric motor operating at 250 deg F. My electromagnets ran at slightly above room temperature, so I chose neodymium magnets for the higher energy product.

The temperatures of a piston pretty much rule out any permanent magnet.

It looked to me like he was describing the magnets being attached not to the piston directly, but to the crankshaft. It's a little cooler there.

And still I give the idea no credence. I mean, it isn't without some merit but really it only appears to be shoving the IMA bits inside the crankcase, like the other guy said. And that's just daft. There are no unique gains to be had by it, it would likely necessitate making the crankcase bigger to accommodate the extra bits - try finding a manufacturer who's going to do THAT - and it would radically complicate the process of working on the engine AND the hybrid system. As if labor charges weren't high enough already.

If you really stuffed an engine full of electromagnets, you could maybe get the engine to turn over. But you would never get useful power out of it.

Electric motors have only a few thousandths of an inch clearance between the rotor and stator for a reason. Increasing that clearance by only a thousandth of an inch measurably reduces power and efficiency.

Pelmear's patent talks about an electromagnet in the cylinder head pulling up on a permanent magnet in the piston when the piston is near the bottom of the stroke. A real world electromagnet that fit in the head would have trouble picking up a paper clip at that distance. It's clear that the Pelmear engine is pure vaporware.

Thanks for inquiring. There is no big battery bank, fuel is used instead of plugging in. You should go to the Energy Technology Company w/ 110mpg Hybrid V8 Engine. website for answers to your questions

When is the electric crankshaft motor adding power? With a V-8, I wouldn't think you'd need any assistance in reaching 400 hp. Does the test car use a battery pack or is this motor generating that much energy and not storing it? If the motor is making that much energy, doesn't that use valuable E85 power just to spin a generator/alternator? It takes energy to make electricity, so how much fuel is used just to power the electric motor crankshaft? Isn't this the same argument as HHO systems? In real applications, it would take a large amount of electricity to generate an ample amount of hydrogen, which would end up making the engine use way more fuel? How much torque can your electric motor crankshaft deliver?

How do the magnets work? Do they pull and then push the piston down? I am assuming the pistons have a piece of iron in them or an electromagnet of some sort. Does that add a lot of weight to the rotating mass of the engine? Is this used in conjunction with the electric crankshaft motor, like running both at the same time?

During the cylinder deactivation, are the valves opening to allow the rotating mass to spin freely or do the valves stay shut? During cylinder deactivation, are the cylinder magnets running and is the crankshaft electric motor running? Can one cylinder effectively push the vehicle along and generate enough electricity to power the magnets/motor?

Do you have any pictures of this engine? I'd like to see what you have aside from an animated Youtube video. It’s patented, so would it hurt to show us a few pics of the crankshaft and cylinder magnets??

Go to your website for answers? I don't mean this in a critical way, but couldn't you just provide them?

[sarguy01]

Your website is vague. There are no pics of the motor. Lots of marketing and little proof of an actual product.

No wonder no one believes anything you write.
