does this works in practical?

car running without fuel
first i will take some water in petrol tank of a car.now i will connect it to a electrolysis box. the electrolysis gets electricity from battery. now 2H2O[water] on electrolysis divides into 2H2 + O2 this in the engine with the help of glow plug combines and gives 2100C -2800C temperature  and water [in gaseous state] with that temp[ car works as in normal case].The water in the exhaust cools down and again goes back to the water tank. By this the cycle continues and car keeps on working.
it will be like this,
Electrolysis box  [water to it comes from water tank ] 
2H2+02 [in engine]    
2H2O + 2100-2800 Celsius temperature [engine works]

water tank

please tell me does it really works out or not

I read the first line and thought - NO - It won't work.

I did read the rest and still have the same opinion.

A 4 cyl 1 ltr engine doing 4000RPM is turning 66.6 time per second!

every rotation pulls in 1 cylinder worth of fuel+ air - lets say 250 cc H +O2.

That's 16666.6 ccs of fuel per minute you can't generate this amount of H + O2 in that time without expending enormous amounts of electrical energy AND having a huge generating plant to give the surface area you would need.

Sorry been tried and despite the Youtube videos insisting it can work - No.

I have seen a electrolysis machine model which can produce 1 mole of hydrogen in 2.6 min.But as per what i know a engine [250cc] won't take 1 mole of diesel in 2.6 min. The energy produced by 1mole of hydrogen is more than 1mole of diesel can generate.
And the machine only takes 150 watts as input.
No and No - Simply on the basis that the big car manufacturers wouldn't have overlooked something so simple and obvious it won't work, and you concern is to produce the volume of hydrogen and oxygen - I have not seen anything that can produce it in ltrs per min with a reasonable amount of energy.

All this in addition to trying to combat some basic laws of physics.

Batteries are best used to direct-drive traction-motors. There is no good sense in using them in that way. (theoretically you could get it to run.)

This works, but not exactly as you think:

What charged your battery?
That energy comes from somewhere. It's a LAW of conservation of energy. The energy required to split water into h2 and o2 is the same amount you'll get back when you recombine them, MINUS LOSSES.

Electrolysis of water is extremely slow -- a few cc's per second at most with a car battery...
Cars consume thousands of litres of fuel/air per minute...so one electrolysis chamber would make 1/(1000cc/litre*1000litre/minute)...one MILLIONTH the energy required to run the engine of an average car. Very generalized numbers, but suitable for this example.

Internal combustion engines are notoriously brutally inefficient. 25% with gasoline...ish.
Using hydrogen as a fuel doesn't really increase this.

If i use platinum i think the process would become fast
And i think the battery would get charged as in normal [when it is used for car accessories]
Even with a catalyst, it would not be fast enough.
The engine cannot power the machine that powers the engine -- that breaks the laws of thermodynamics. Try charging a battery with a dead battery and see what happens.

I even thought of using the sound from the engine to produce electricity
sound is 1/10000th of the energy coming from the engine.

sir,can i know how a oxy hydrogen torch could work if the electrolysis process is that much slow.please tell me
HHO torches use bottles of H2 and O2 that were refined in a factory using massive industrial processes. They do not supply the gases "on demand" from electrolysis of water.
some home models do, but much, much lower quantity :)
Because an oxyhydrogen torch
A) uses a lot less energy than a car
B) uses a lot MORE energy than a car battery could provide (it's plugged into the wall
