What is the function of a spark plug in a vehicle?
Answers:
The spark plug ignites the air/petrol mixture in the cylinder head with a spark. The explosion it causes drives down the piston which is connected to crank shaft which turns as the piston goes down. This happens in sequence in all 4 or 6 cylinders thereby maintaining the crank shaft continually turning. Yes it does spark all the time as the car is kept moving in this way. The crank shaft is connected to the road wheels via a clutch and gear box.
The spark is made by an electric current passing through a coil or some other electrical circuit to increase it's intensity and by some form of sequencer called a distributor this current is fed to all cylinders in turn.
Hope this helps.
Yes, it still sparks while the vehicle is in motion.
The spark plug is quite simple in theory: It forces electricity to arc across a gap, just like a bolt of lightning. The electricity must be at a very high voltage in order to travel across the gap and create a good spark. Voltage at the spark plug can be anywhere from 40,000 to 100,000 volts.
The spark plug is what keeps the car running. The engine sucks in a mix of air and petrol and the spark plug ignites the mixture.
A spark plug ingites the petrol/air mixture in the cylinder.
Every time the piston fires, the spark is used to ignite the fuel/air mix that makes the piston expand and drive the shaft. It doesn't self ignite.
quit cheating on you homework..otherwise you would know and you, my friend, obviously know nothing about cars!
A spark plug (also very rarely nowadays in British English, a sparking plug) is an electrical device that fits into the cylinder head of some internal combustion engines and ignites compressed aerosol gasoline by means of an electric spark.
the spark plug fires every time the piston comes to the top of the stroke on compression ,this is controled be sensors and coils and computers
the ignition of compressed fuel moves the piston in each chamber,so every time one piston is forced down another piston is forced up and so on.so yes even the car is in motion the spark plugs do ignite
a brief description?
The spark ingnites the petrol/air mixture
when the engine is runnig (petrol) it need contiuas power (spark) as not like a diesel it does not have the compresion to creat the heat! with me so far? ( a diesel no plugs ok)
now at just befor tdc (top dead center ) of a stroke piston very close to top, on modern day car ecu will tell the coil to fire Whitch then corses the plug to fire then cousing a bang in the chamber the fuel and air mix send the piston back down at great force back down the bore.
this is the power stroke ok!
hope this helps more
let me guess a female ? hah
Got to be a split to ask a question like that.
yes it does spark when the car is moving it works on electrical power
spark plugs are used in the piston chambers of your engine for when the cylinder draws fuel in and compresses it. As it is compressed, the spark plug creates a spark (much like the ones created on a gas stove) which ingnites the petrol and pushes the piston back up. The piston is connected to the crank shaft which, through the flywheel and the propshaft make your wheels turn.
The spark plugs don't actually help your car start up. Instead, there is a separate motor (the starter motor surprisingly) which is electirc and helps turn the main engine over so that the pistons will start moving in the first place.
Hope to have been of help.
