To lower compression you would have to increase the combustion chamber volume at TDC. Since piston and rod heights are fixed the only way to increase chamber volume is to alter the stroke.

I suggest mentally picturing the system on end and consider how the cylinder bore and crankshaft axis of rotation are both fixed.

I'm lucky if they even put the plates on the rack and wipe down their equipment when done at my gym. The evening crowd is lazy.

Being able to tune the compression ratio gives you the best of both worlds in the same engine. |
