A 75 cc engine has following parameter as 75 cc: 

Explanation:

Cylinder block is the important part of the engine, where the reciprocating motion of the piston creates the moving boundary of the combustion system.

The Boundaries are:

Top Dead Centre:

It is the centre where Piston is farthest away from the crankshaft. It is denoted by TDC.

Bottom Dead Centre:

It is the dead centre where piston is nearest to the crankshaft. It is denoted by BDC.

Swept Volume:

It is the volume swept by the piston by travelling from one dead centre to another dead centre. It is denoted by Vs

Swept Volume = Volume of cylinder at BDC (VBDC) - Volume of cylinder at TDC (VTDC)

Clearance volume:

It is the volume of the combustion chamber above the piston when it is a TDC. It is denoted by Vc

Compression Ratio:

It is the ratio of total volume of the cylinder when piston is at the BDC to the clearance volume. It is denoted by r.

\(r = \frac{{{V_{BDC}}}}{{{V_c}}} = \frac{{{V_s} + {V_c}}}{{{V_c}}} = 1 + \frac{{{V_s}}}{{{V_c}}}\)

1. Fuel tank capacity: This refers to the amount of fuel the tank can hold, usually measured in liters or gallons.
2. Swept volume:
   • This is the volume of air/fuel mixture an engine can draw in during one complete engine cycle, measured in cubic centimeters (cc).
3. Clearance volume: This is the volume remaining in the cylinder when the piston is at top dead center, usually measured in cc.
4. Cylinder volume: This is the total volume of the cylinder, including the swept volume and clearance volume, measured in cc.

Since the given value is 75 cc, it matches the definition of the swept volume
