The compression ratio of an engine is the ratio of the volume of the cylinder and combustion chamber when the piston is at the bottom of its stroke (the maximum volume) to the volume of the combustion chamber when the piston is at the top of its stroke (the minimum volume).
In this case, the maximum volume of each cylinder is given as 500 cubic centimeters and the minimum volume is given as 50 cubic centimeters. Therefore, the compression ratio can be calculated as follows:
Compression ratio = (maximum volume + combustion chamber volume) / combustion chamber volume
We know that the maximum volume is 500 cubic centimeters, and the minimum volume is 50 cubic centimeters. Therefore, the combustion chamber volume can be calculated as the difference between the maximum volume and the minimum volume, which is:
Combustion chamber volume = maximum volume - minimum volume
= 500 - 50
= 450 cubic centimeters
Now, we can substitute these values into the compression ratio formula:
Compression ratio = (maximum volume + combustion chamber volume) / combustion chamber volume
= (500 + 450) / 450
= 1.1111 (rounded to four decimal places)
Therefore, the compression ratio for this engine is 1.1111 or approximately 1.11 to 1.
