You got any actual figures.
All that I remember about it was platitudes.
ANd nobody says theire idea is a dog
You are AGAIN thinking of only one issue at a time>
The problem is only when you first start up. AS SAID, you would size the battery to manage the peak. You dont' accelerate a car for 20 seconds
Sorry but you're missing the whole point by being single-thinking. Build in what the Stirling engien is doing durign the acceleration of the vehicle and what it is doing durign coast and steady speed ?
Nobody's sayign there are NO batteries but it wouldn't need the SHED LOAD that current hybrids are running
Even if allowed to run at optimim efficiency, then an Otto will be WELL short of the efficiency of a Stirling -- or another "imporoved" combustion engien
First balancer shafts are requried because of the ROTATION rpbblems.
Do you grasp that ?
So it is ONLY reciprocating weight that is the problem and the only part of a Revetec is the PISTON -- no strong conrod or crank out there
So you first recognise that it's a fraction of teh nromal engien weight. So you've done THE MOST IMPORTANT step already which is minimising the mass. Then if necessary they would apply for balance by multiple cylinders -- jstu in teh same way a V8 manages optmimum any paired Revetec piston seupt should.
That's a simplification that only works as long as you're not trygin to maximise the power output or the efficiency. Sadly I believe you've forgotten more than you think
2-strokes are the moust inviromental engines.
BS and you provide the answer yourself - as I had already said.
Rubbish
You can't make an oil have long chains to maxinmise lubrication AND burn efficiently. You are thinking of only one thing at a time again.
let's now jsut save me the hassle. You're wrong.
NO it doens't !!!
You are wrong.,
You are NOT thinking of the whole system again>
A crank does not match the optimal piston pressures because of the angles !! This is what the Revetec designer ( and many others over hte decades ) is trying to recover energy better.
Sorry, think about the CRANK positin as well as piston and do the vector force calucaltion and see how much is goin in to provide OUTPUT force.
Because you've NOT actually looked at the force vectors in all the components.
Do it, you will learn and understand.
Yeah but why is a ball bearing coming in to it ?
Do you mean NEEDLE bearings ?
Needle bearings can handle the pressures.
I think you are still thinking of only one thing at a time. Different materials could provide it, perhaps sacrificial. Oil bath coud deliver it at higher speeds onto the mating surface. WOudl still need strong material tho as it won't benefit from pressure build up from rotation the way a crank does.
But as you are not clearly aware the forces beign talked abotu are the SAME as a normal Gudgeon Pin on a piston is handling
So how come it survives there and yet won't here ??
MATERIALS and oil supply -- the challenge will be having ENOUGH pressure to ensure a minium thicnkess of oil to ride on.
