why do the engine of car gets seized if we put sugar in fuel tank?

It doesn't.  The Mythbusters proved that the engine is not harmed very much even with a huge amount of sugar in the gas.

The wooden engine would be highly flammable and would explode during ignition or driving. The wooden seat would be extremely uncomfortable, and the wooden wheel would have to control a wooden rod that controlled a wooden gear that controlled a wooden rack/pinion that controlled the wheels, or the ones that turn anyways.

Most would settle to the bottom of the tank and join all the rust that's already there. Carbon and Potassium Nitrate aren't soluble enough in gasoline (and neither is the graphite form of carbon used to polish the granules in commercial gunpower).\n\nHowever, the sulfur would partially dissolve and eventually ruin the car's catalytic converter. It might even lead to a bit of a smelly exhaust for a while.\n\nNow, if you didn't mean gunpowder, but mean nitrocellulose (which is a more common propellant in modern guns), then you could give him a nice octane boost. However, it takes several days to a week for nitrocellulose to dissolve in gasoline (depending on temperature and 'shaking'). So, don't expect much very soon.\n\nI think the thing you are missing here is that gasoline isn't burned in the tank. Only a small, filtered amount is burned in the engine at one time. That's why you get miles per gallon and not gallons per mile.

The ability of gasoline to float on water is not CALLED any of those.\n\nIt is an effect that arises from the specific gravity of gasoline being less than one.\n(this implies that the density of petrol is less than the density of water, and so petrol floats on water.)

If you're doing this to save on fuel economy, you're kind of missing the point.  Your engine needs the same stoichiometric amount of fuel to run, no matter the dilution level.  In other words, your engine will burn the same number of gasoline molecules, whether or not there is water present.

That 'Hard Luck' knows NOTHIN about cars!  By adding more air to your engine, your air-fuel mixture improves resulting in less fuel required to get the same if not better effect.  So, you get better fuel economy and possibly up to 10 extra ponies squeezed under the hood.  I have witnessed this first hand with our Honda fourwheeler after installing a K&N air filter and a custom Glass pack exaust. It sounds fricken AWESOME!

You've taken the first step in a good scientific inquiry.  You observed a phenomenon and began trying to explain it.  Now you can work toward an answer.  You could see if sugar (glucose?  sucrose?) is a molecule similar to salt for elevating the boiling point of water. (It depresses the freezing point like salt does.)  You could try measuring water just as it boils, and then with the same instrument, measure sugar-water just as it boils, and see if it really is elevated.  You can learn more about the subject by reading.  The melting point of glucose (C6 H12 O6) is 113 degrees Centigrade, higher than the boiling point of water.\n\nThen you can formulate theories as possible explanations.  You've started doing that.  Then you can investigate those.  Here's another.  Perhaps dissolving sugar is an endothermic reaction.  Mix some sugar and water which are both at the same temperature.  Does the temperature of the mixture change?\n\nIt takes a certain amount of energy to raise the temperature of water.  Look up the definition of calorie.  It takes additional energy to convert it from its liquid state to its gaseous state.\n\nIt often takes some discontinuity for a supercooled solution to freeze or form crystals, or for a superheated solution to boil.  The bottom of the pot has such discontinuities, and particularly irregular parts of the pot are where boiling likely starts.  When you add granulated sugar, you are adding lots of discontinuities.  What happens when you add dissolved sugar instead of granulated sugar?\n\nKeep good records, sign and date your notes and get them witnessed periodically.  They could be your first steps toward a very good science fair project or perhaps a bigger discovery and a patent.  Then, tell the world I helped you along.  That would REALLY make my day!

Car manufacturers were forced to switch to fuel injection do to government regulations on emissions. Regulations which do more harm than good I might add. Fuel injection is good for most vehicles, but INEXPENSIVE sports cars would be better off with carbs.

Gasoline is ignited by the spark plug, which causes a small explosion in the motor. The explosion causes pressure, which moves the piston, which moves the crank, etc.

The goal of a carburetor is to mix just the right amount of gasoline with air so that the engine runs properly. If there is not enough fuel mixed with the air, the engine "runs lean" and either will not run or potentially damages the engine. If there is too much fuel mixed with the air, the engine "runs rich" and either will not run (it floods), runs very smoky, runs poorly (bogs down, stalls easily), or at the very least wastes fuel. The carb is in charge of getting the mixture just right. \n\nOn new cars, fuel injection is becoming nearly universal because it provides better fuel efficiency and lower emissions. But nearly all older cars, and all small equipment like lawn mowers and chain saws, use carbs because they are simple and inexpensive.

You say it runs good when you block the air intake. That means the engine is getting less air, creating a richer fuel/air mixture. Remove the carb and clean it. The pilot jet might be restricted (clogged), and not allowing enough fuel to enter. Turn on the choke a little. If it runs better, then that's the problem - clean the carb.

more info please. have you made sure you are getting gas to the carb? all the fire in the world cant run an engine with a bad fuel pump or clogged filter. are you getting spark? pull a plug wire and sick a screw driver in it. place the screw driver near the manifold(less than half an inch from it) and turn the engine over. if no spark jumps from screw driver to exhaust manifold you still have a spark issue. if you are getting fire then it should be a fuel issue. if you have both fuel and fire and it turns over but doesnt catch then it gets interesting. also if it turns over but jerks hard you may have the timing out so far it can't catch. eliminate possibilities one at a time and eventually you will eliminate the problem.

The sugar in the mentos reacts with the carbonate in the coke causing gasses to form and pressure to increase inside the bottle, when this pressure is released the gasses will shoot out causing it to "rocket".

The burning of the fuel (chemical) caused the water to turn to steam (heat) which causes the piston to move the rod (mechanical) which moves the engine,\n\nIf you are looking for more in-depth,

Separating the Hydrogen and the Oxygen from regular water is a simple grade school physic's experiment. I have included a link to a experiment page. Now whether it is illegal in Great Briton, I do not know. Now why we don't use it, you would have to ask the major car manufactures that question. The technology is not new, there has been powerful fuel cells floating in outer space for almost 4 decades. The problem with hydrogen as a fuel, is that if it expands uncontrollably you will have one big explosion on your hands.
