The Basics\nWhen most people think about motors or engines, they think about rotation. For example, a reciprocating gasoline engine in a car produces rotational energy to drive the wheels. An electric motor produces rotational energy to drive a fan or spin a disk. A steam engine is used to do the same thing, as is a steam turbine and most gas turbines.\n\nRocket engines are fundamentally different. Rocket engines are reaction engines. The basic principle driving a rocket engine is the famous Newtonian principle that "to every action there is an equal and opposite reaction." A rocket engine is throwing mass in one direction and benefiting from the reaction that occurs in the other direction as a result.\n\nA rocket engine is generally throwing mass in the form of a high-pressure gas. The engine throws the mass of gas out in one direction in order to get a reaction in the opposite direction. The mass comes from the weight of the fuel that the rocket engine burns. The burning process accelerates the mass of fuel so that it comes out of the rocket nozzle at high speed. The fact that the fuel turns from a solid or liquid into a gas when it burns does not change its mass. If you burn a pound of rocket fuel, a pound of exhaust comes out the nozzle in the form of a high-temperature, high-velocity gas. The form changes, but the mass does not. The burning process accelerates the mass.\n\nAnd that is how the rocket moves foward

It depends entirely on the application for which the motor was designed. \n\nMany very powerful motors (like the starter on your vehicle) are designed specifically to deliver maximum torque for very short periods of time. If you were to continuously crank this type of DC motor, it would burn out quite quickly.\n\nOther motors (like the DC fuel pump motor or the winshield wiper motor in your vehicle) are designed to run reliably and continuously for hundreds of hours without any maintenance (these motors often outlast the vehicle.)

A brushless alternator works very much like a regular alternator: a rotating magnetic field induces an AC in a stator field winding. Whereas in regular alternators the rotating magnetic field comes from permanent magnets or DC excitation carried to the rotor through slip rings and brushes, in brushless alternators the field excitation is coupled to the rotor by AC induction and then rectified. Voltage is regulated by adjusting the intensity of the rotor field. (Note that PM rotors can't be regulated this way.)\nRef. 1 below is another yahoo answer that describes the workings well. Unfortunately the link it refers to apparently no longer exists. The other refs. may be helpful. Ref. 3 descibes an experimental design that uses a synchronously rotating stator field, based on rotor position sensing, to excite the rotor field.

i have study about this before 3 yrs but i will check my memory. this engine is called so because the fuel is burnt inside the combustion chamber means internally.it consists of a combustion chamber having an inlet valve so that fuel can enter inside the chamber and an outlet valve to forward the burnt fuel to the other stage. it also consist the piston which is one of the main parts of the engine without it we cant rotate the wheels. piston is also is in a closed cylinder which also have two valves andperform the same functions as they do in comb. chamb. after piston there is another cylinder which is used to throw out the exhausted fuel outside. i think this is enough

It's a very clever device actually.  You have a circular armature that spins in the middle sorrounded by circular coils.  Both of these parts have conducting coils of wire in them. So you have a series of electromagnets shaped around each other.  \n\nThere are also switches that move the current around the particular sections.  When you plug the motor in, the magnetic field can be manipulated so that it moves around in a circular path.  The magnets in the armature are drawn to it and move toward it.  But as soon as it gets close, it is switched off and the next one along the circle is turned on.  Again, pretty tricky to make, but we've figured it out - great device.

The jet engine has impellors inside it thatpull air into the engine through a channel called a venturi that tapers towards the center of the engine to a very small diameter.  The force of air through the venturi creates large amounts of heat from friction (like a diesel engine), and what happens is the jet fuel is introduced just before the smallest part of the venturi, causing it to combust and create the energy, or "thrust" you mentioned.  At the rear of the engine, there are dampers to restrict the output of the thrust, controlling the vehicle's speed.  The weight of the vehicle MUSt be less than the thrust that is put out by the engine, or the engine won't have enough power to move the vehicle.\n\nAs far as recycling, no idea.  Hoped the jet answer helps.

Turbochargers are a type of forced induction system. They compress the air flowing into the engine. The advantage of compressing the air is that it lets the engine squeeze more air into a cylinder, and more air means that more fuel can be added. Therefore, you get more power from each explosion in each cylinder. A turbocharged engine produces more power overall than the same engine without the charging. This can significantly improve the power-to-weight ratio for the engine. \nIn order to achieve this boost, the turbocharger uses the exhaust flow from the engine to spin a turbine, which in turn spins an air pump. The turbine in the turbocharger spins at speeds of up to 150,000 rotations per minute (rpm) -- that's about 30 times faster than most car engines can go. And since it is hooked up to the exhaust, the temperatures in the turbine are also very high.\n\ni sugest to you to read my source

Here are a couple of web sites that approach this in different ways. \n\nhttp://www.circletrack.com/techarticles/84199/\n\nhttp://www.diracdelta.co.uk/science/source/e/n/engine%20excitation%20mechanisms/source.html\n\nHope these help.

yes:\n\nThe first answer is in the right direction.\n\nA reaction engine is one that moves in a direction opposite to the thrust of combustion.\n\nA reaction engine works on the basis of Newton's third law of motion: \n\n"For every action there is an equal and opposite reaction."\n\nIn a reaction engine fuels are burnt and the extra pressure due to formation of more volume of gases is directed to get out of a nozzle. This forms "action"\n\nAs a result of action the engine or the body containing the system moves in opposite direction.\n\nRockets and Jet Planes are the examples of reaction engine.\n\nThe movement of a balloon as a result of escaping gas from an opening is one very simple example.

In order for gasoline to produce power in an engine, it must burn under pressure. What happens is the fuel mixture enters a cylinder then is compressed by a piston to place the fuel under pressure. Once under pressure, the fuel is ignited to burn (explode). This drives the piston back down and the up/down motion of the piston moving is captured to use as power to drive a machine. This process happens over and over again very quickly within an engine.\n\nFour stroke engines work like this:\n1. The fuel mixture enters the cylinder while piston is going down \n2. The mixture is compressed while piston is going up\n3. Fuel is ignited (combustion) forcing piston down (this is the powerstroke)\n4. The spent gas/smoke is pushed out by piston going up\n\n\nTwo stroke engines take a short cut:\n1. The fuel mixture enters the cylinder while piston is being forced down from combustion (powerstroke)\n2. The spent gas/smoke is pushed out by piston going up\n\nSince the two stroke engine combines the intake and exhaust   steps they aren't as efficient. This is because there is still some smoke left in the cylinder during combustion, and some spent fuel being forced out with the smoke.\nThe four stroke engine purges the smoke before taking in new fuel.

"turbo" used in normal piston driven engines uses the exhaust gasses energy to drive a (typically) radial turbine that is connected to a compressor that compresses the intake air. \n\nThe increased amount of air (mainly the oxigen in interesting) allows to add more fule to the mix and create a larger explosion in the cilinder yielding more power.\n\nThe air can optionally be cooled using an "intercooler" (air-to-air heat exchanger)\n\nFor diesel powered engines the result is an increase in power of the engine and an improvement of the fuel economy. For gasoline powered engines the results are an increased power, but the fuel economy might go either way.

Most of the time, it's a turbocharged engine.

Umm, that depends on the pulley used.  The smaller pulley on the blower, or the larger on the crank, the faster the impellers spin, the more pressure, and HEAT are generated.  Thing is, before long you're creating so much heat that you lose power.  Since engines, intakes, fuel, and intake coolers (intercoolers, alcohol injection, etc..) vary from application to application, there is no one correct answer.  And even if you could run absolute maximum theoretical pressure, which you would never want to run becasue you'd get so little power, you would burn up the blower and/or your motor in a matter of seconds.  literally.  So you probably want to talk to Paxton; tell them what car, engine, mods, etc., and they will tell you how to get the most out of that blower.  Good luck!

Im not really clear what you mean by settings but the best physical part swap for acceleration in ring and pinion swap to lower the final drive ratio which means the engine revs faster hope i could help

The crank shaft is what connects the pistons together with the transmission to change reciprocating motion (up and down) into rotating motion (turning.  This process is necessary to turn your wheels so you can get to work.

Okay... If ur serious then I'm game!!  The piston is attached to the piston rod.  When the rod is pulled down by the crackshaft, kinda like bicycle pedals.. the piston draws air into the cylinder.  Then the crankshaft pushes the rod and piston up causing compression.  Then the spark plug ignites and blasts the piston and rod back down creating power.  Then the crankshaft pushes the rod and piston back up expelling the waste.  The piston is the 'plunger' of the system, kina like the black rubber plunger in a hypodermic needle.
