hehe, let's start the ignition timing control discussion ba.
first I clearify some basic points.
timing means: when to ignite the fuel and air mixture.
ignition is done through applying 15000-20000 high voltage
to the spark plug and generate a spark. hehe.
usually it needs to be done before piston reach TDC, since
fuel needs some time to burn. it is often represented in
degrees (rotation angle for crankshaft) before TDC.
for my car, during idle, the timing should be 15+-2 degree.
but don't think

enh. right. it is +-2 degree on my car.
hehe. let's continue.
since we know what is timing. then it comes how the car can set
timing. how to control when to generate the spark?
on traditional cars, there is one important device called distributor.
it is devoted purely for this purposes.
usually a distributor is mounted on one top side of engine.
there is a shaft inside and driven by the camshaft.
and there is a small rotor mounted on the shaft.
when engine rotates, the distributor shaft will rot
