Why does ignition occurs during the power stroke in spark ignition engines?

In normal running conditions, the ignition does not happen during the power stroke, but just before, at the end of the compression stroke, because it takes time for the burn to propagate through the ...

Is it possible to have a good looking spark but but still not suitable for ignition?

Inside the cylinder is quite a hostile environment. What looks like a strong looking spark at atmospheric pressure outside of the cylinder can become nothing at high pressures in a fuel rich ...

Should I retard the ignition timing on higher RPM on natural aspirated engine?

Because there is less time for ignition events to occur at higher RPM, the timing should be advanced. If you retard the timing at higher RPM, the ignition event will be happening too late in the ...
