motor explained??

[roscoe]

ok so i have helped my buddies and worked on a few cars... but i'd kinda like to find a pretty good, in depth explination of how a motor works exactly. i kno that alot of u out there r thinkin what a retard but i'm new in the game so whatever. so plz keep the hating to yourself. thanx for any info

[slostang]

suck squish bang blow...

[SixSquared]

Air enters through intake valve

Fuel injector squirts in fuel

Spark plug goes kaboom

pushes piston down

Motion of other pistons being pushed down turns crank

makes power.

That's in the most BASIC sense.

Well, there is an external casing that has two magnets mounted on either side of it. Then there is an armature/rotor assembly that is wound with copper wire that protrudes through the center of it and out through the front of the casing. Then there is usually a gear connected to the portion protruding from the casing. And on the other end of the armature shaft there is a cap to the casing that contains some brushes that transfer electrical current to the armature. When the casing is charged with - current and the armature is charged with + current the armature will begin to spin inside the magnets.

repped for explainng a MOTOR!!!!

pretty sure he's talking about a car engine/"motor"... not an electric motor.

somebody got it....

[roscoe]

somebody got it....

so the "ALL MOTOR" section on this forum is electric cars then?

[roscoe]

u kno what i mean. take the hating elsewhere

I'm glad someone knows the difference!

where are my reps for finding you a diagram AND explaining it?

Intake, compression, ignition, exhaust.

Actually its

Intake, Compression, Combustion/power, Exhaust

[Vteckidd]

Intake
First stroke, starts with piston at TDC (Top Dead Center). This term refers to the location of both the piston and the crankshaft. TDC refers to the point where the piston is at the top of the bore and the crankshaft is at 0 degrees of rotation. Due to the geometry involved in connecting the pistons linear travel to the crankshafts circular motion, it is possible to have the piston at the top of the bore and the crankshaft located some degrees before or after 0 degrees of rotation.

Compression
when the crankshaft has reached 180 degrees after TDC, it is referred to as BDC or Bottom Dead Center. At this point the piston is at the bottom of the bore and is ready to begin its travel back up the bore to compress the air and fuel taken in on the intake stroke.

POWER
When the piston returns to the top of the bore again, the crankshaft is now at 360 degrees of rotation. At this point the mixture ithat is compressed is expanding rapidly because of the combustion event caused by the ignition system firing the spark plug. This expansion is where the negine produces its power and actually forces the piston back down the bore and applies rotational force to the crankshaft.

EXHAUST
The Final stroke begins when the piston returns to BDC and begins to push the expanded and burned up gases back up and out of the cylinder to clear it for the next incoming cycle. At this point the crankshaft is at 540 degrees of rotation and will complete the cycle at the top of the cylinder at 720 degrees of rotation.
