Cam Experts: Lobe Separation Angle?

effective compression

Is what the engine sees when it's running, depending on VE it can be lower than dynamic.
How good is your intake and cylinder head? How fast is the cylinder filling.

Ok, maybe it should be called effective stroke length.

Either way it’s still a ratio. That’s like saying you have a variable compression ratio engine.

It’s always the volume above the piston at TDC over the volume above the piston at BDC.

The relationship of those two things never changes.

It’s the same with effect compression ratio engine. It doesn’t change.

I agree and the point the intake closes has an effect on the effective ratio.
are we clear, I said are we clear? lol

This link seems to have a decent explanation of effective compression ratio and all the variables related to it.

lol yes sir! We are clear lol

How efficient too I might add.
