Please tell me that how is petroleum used to move a car?
Answer:
In a car engine, a petrol/air mixture is supplied by a mixing device called a carburettor (or injector), which feeds the mixture into the intake manifold.
When the engine is running, the cylinder pistons go through the following timed sequences.
1...Intake stroke..the intake valve opens and a portion of fuel/air mixture enters the cylinder on the 'Down-stroke' or Suction stroke.
2...This is followed by upward or 'Compression' stroke..All valves are closed and, the mixture is compressed to a high pressure.
3...Next is the downward 'Power' stroke..All valves remain closed. Just as the end of the upward stroke is completed, the electrical system (distributor), provides power to a spark plug which ignites the mixture. The ignition causes an explosion as combustion of the mixture takes place and the huge increase in pressure and volume due to this, forces the piston down.
4...Finally, on the next upward stroke, the exhaust valve opens and the exhaust gases are expelled into the exhaust pipe to atmosphere.
The reciprocating motion of the pistons is transferred to the camshaft and converted to rotation which, in turn, drives the gears in the gearbox from where the drive shaft goes to the 'Differential' gear driving the wheels.
The above sequence is called the 'Otto' 4-stroke cycle.
A simple way to remember the cycle is ...1..'Suck', 2..'Squeeze', 3..'Bang', 4..Blow.
The exhaust gases are the products of combustion and consist mainly of CO2 and Water vapour.
If the air/fuel mixture is not quite right and air content is a little low, then some CO (carbon monoxide) may be present.
Other gases will include nitrogen compounds and maybe sulphur compounds.
(If leaded petrol is used, then lead compounds are also produced).
A mixture of air and "petrol" is fed into the piston of the engine where it is ignited. This mixture undergoes a chemical reaction which generates a great deal of heat and energy. The increase in heat/energy inside the piston increases the pressure acting on it, driving the piston upwards. This corresponds to mechanical work which moves the car
Petroleum is a a carbon molecule. In a car. the carbon molecule and oxygen/misc air is put into a piston. a spark is delivered and the carbon is broken up and made into mostly CO2, HC, NO2 and H2O, which takes up much more space than the C6H12O6. The new "air" pushes out the piston. the moving piston turns a crankshaft, which eventually turns a wheel on the car.
A motor is basically an air pump.
It is burned, which makes a mini explosion, it pushes the piston down, while the other piston is pushed up . And it goes on and on and on on on on so forth
petrol is mainly used as a combustion medium inside any petrol engine used to drive cars. The combustion of petrol produces pressure inside the combustion chamber of the engine which in turn is used to cause the motion of the piston inside the combustion chamber. The petrol is sprayed in the combustion chamber of the engine and is ignited by the carborator. Petrol after ignition is converted into gas which creates high pressure inside the chamber and pushes the piston outwars. The gas expands and as the pressure inside the ignition chamber becomes less than the atmospheric pressure the pistons are again pushed inwards. Again the ignition takes place and same process is repeated again and again causing the motion of vehicle. The pistons are connected to the shaft which is connected to the wheels of the automobile which in turn drives the vehicle. The same principle is used in diesel engine, the only diffference is that in diesel engine we use diesel as fuel or combustion medium.
The petrol is drawn out of the gas tank and up the fuel line to the carbeurator or fuel injection system by the fuel pump. The gasoline is then mixed with air to create a certain ratio od air to fuel. The air/fuel mixture is then sprayed into the combustion chamber and is ignited by the spark plug, which causes the fuel to explode. The explosion drives the piston down, turning the crankshaft, spinning the flywheel in the transmission, which turns the driveshaft, which turns the gears in the rear axle, which turns the wheels.
(It's explained more in-depth at howstuffworks.com)
Petrol vapor is injected into a cylinder by a fuel pump and is compressed on top of piston by the piston rising and compressing the gas When the compression is complete the coil sends an electrical charge into the spark plug. the electricity jumps the gap in the sparkplug. This spark ignites the vapor which causes a small explosion to drive the piston down which turns the crankshaft which brings another piston up into firing position as well as turning the flywheel.
The trick is to get a piston to rise the first time. This is done with an electric motor called a starter.
After that it is similar to the old song "bones" by Mills Brothers I believe:
Piston connected to piston rod
Rod connected to crankshaft
crankshaft connected to flywheel
flyweel connected to clutch
clutch connected to transmission
transmission connected to drive shaft
drive shaft connected to differential
differential connected to axle
axle connected to wheel
and wheel goes round and round
