Cylinder volume (cc)

Inside our cylinder, the piston is reciprocating to provide power to the car. Displacement is the volume swept by the piston during this process, which is the effective volume, and the cylinder volume is the total volume of the cylinder. The cylinder volume is actually larger than the displacement (as to the question of why the displacement number is larger, it is Since the displacement has an integer logic, it is impossible to write a displacement of 1.999 liters.) We know that car work is through the burning of fuel. The fuel must be compressed in the cylinder first, and then it will instantly burn and expand the outline power.

The general car's compression ratio is about 10:1 or so. It can be understood that 10 is the cylinder volume, and 1 is the invalid volume, and their difference 9 is the displacement. If we compress the fuel to a volume of zero, it is that the volume is equal to the displacement, and this is impossible.
