  • pls give ur ideas...... can we work the piston of engine using the principle of magnetic levitation.i.e.using the picton that made of superconducting material and giving magnetic force on the cylinderical head by changing the poles of magnet....and my the continuous repulsion and attraction the piston will work...is it works...????/

    Worth trying out practically. But maintaining super conductivity in higher temperature is always a challenge when we have moving parts

    So piston has to be ideally at lesser temperature to maintain super conductivity and this will make the need of Highly effective Temperature sink (Heat sinks). This will increase the size of Engine which is not advisable
    Are you sure? This action cannot be undone.

    but insted of super conductors can we use the same strong magnet at the top of the cylinder head..thus the magnets ll repels each other at a moment and attracts at another moment ...thus the pistons ll work as like a two stroke engine ...is it feasible?????do we need high power to rotate that magnet above the piston???

    not sure but we will have really poor efficiency and the driving power we get will not be that high to run a large vehicle

    We have to test it before we can say anything more SO I am out of this talk sorry

    I thought of this idea a couple of years ago. i tried developing it, and this is what i found:

    firstly you need to create a very strong magnetic field to cause the attraction and repulsion of the piston, and this can be achieved only by using electromagnets. and for this you require a large amount of current.

    so then with this you are back to square one, because since electricity is involved, then it is better to use an electric motor, instead of wasting time developing this engine.

    second: even if this thing works, it won't be applicable for automobile purposes, because speed control will not be possible (if natural magnets are used).

    @#-Link-Snipped-# I have a small doubt in it.
    Consider we are using eitger attraction or repulsion because the momentum will be able to move the piston from TDC to BDC and vice versa.If you know kindly share the current required to do it.Will the 12 volt or 24volt battery able to do it?

    the momentum will not remain for long, thanks to the frictional resistance at the bearings and journals of the crankshaft.

    So it is better if we use both attraction and repulsion. As for the voltage, well we can use any voltage, and the final mechanical output power will depend on the magnitude of the voltage used.

    as for the mathematical relation between the input voltage and the output mechanical torque: that we will have to discover.

    @#-Link-Snipped-# : There is no point in using magnetic levitation in slider crank mechanism.Why waste your energy and time in running a mechanism which cannot be balanced. Try out something following the same priniciple in a balanced mechanism. You will save a lot of weight because you will not have balancing weights. try out something which can rotate about its own axis using magnetic levitation.
