9.5 to one compresion and above HIGH......7 To 9.5 LOW. Fuel is compressed by piston and head before fuel is ignited. More compression means more violent explosion in cylinder.More compression usually means more power. Computers help us safely use higher compression ratios with-out pre-ignition .(pre ignition-BAD). Pre-ignition often called PINGor KNOCKING. Hope this helps a little. I tried to keep the explanation simple. Deisel engines usually have higher compressin ratios due to fact Deisel is not normally as volatile (explosive) as gasoline.You must study for a long time to get it all correct ! Disassembling an engine to measure eveyting (Volumes,etc.)is part of blueprinting an engine.This can be fun and if I can do it so can you.If you build an engine from scratch you must blueprint to be absolutely certain of your comp. ratio
