There are several means by which the compression ratio of an engine might be reduced although all involve extensive mechanical rework to accomplish.
1) Remove the heads from the motors and grind the compression chambers of the head(s) to make the area larger.
2) Install replacement pistons that have a different shaped piston top (usually a larger "dished" area)

How do you calculate compression ratio?
compression ratio = compressed size / uncompressed size the ratio should be between 1 and 0 (multiply with 100 to get the ratio in percent) a ratio greater than 1 means, the compressed size is actually greater than the uncompressed size a ratio just below 1 means bad compression the lower the ratio, the better the compression
How does compression ratio affect engine efficiency and performance?
Engine efficiency is increased though compression ratio by allowing a more thermodynamic energy to be converted into mechanical energy. Energy transfer is the key to efficiency.
What is the compression ratio of diesel engine?
between 18 and 25 to one depending on engine I agree. It all depends on what engine you have.
What is the total displacement in cubic inches of a v6 engine when the compression ratio is 3-3 and 1 half Does it equal 173 cubic inches?
The compression ratio doesn't deal with the displacement, the bore and stroke do. If it's a modern engine it should say the size of the engine in liters. You can use this to convert the engine size to cubic inches. A 173ci engine is a 2.8L engine when converted.
What is the compression ratio for an engine if each cylinder has a maximum volume of 500 cubic centimeters and a minimum volume of 50 cubic centimeters?
Compression ratio is exclusive to each cylinder, though they will all have the same result if they are the same dimensionally ( and they always are) > Divide the total engine capacity by the number of cylinders, this gives the capacity or swept volume of each cylinder (bore * stroke) > So in a 2.0 (2000 cc) litre 4 cylinder engine, each cylinder has a 2000 / 4 = 500 cc swept volume (bore * stroke) > The combustion chamber is the volume remaining at top dead centre (TDC) > Compression ratio = volume at BDC (swept volume + volume at TDC) / volume at TDC
