The Volume of an Engine Cylinder calculator  Engine Cylinder  computes the volume (V) of a combustion engine cylinder based on the bore (diameter) and stroke length (see diagram).

INSTRUCTIONS:  Choose your preferred units (defaults are inches), and enter the following:

• (b) The diameter of the cylinder's bore.
• (s) The stroke length of the piston in the cylinder.

Cylinder Volume: The calculator returns the cylinder volume (V) in cubic inches.  However, this can be automatically converted to other volume units (e.g. cm3) via the pull-down menu.

### The Math

The formula for this calculator is as follows:

V = π * (b/2)2 * s

Related Combustion Engine Calculators:

• RATIOS AND LENGTHS:
• Bore (diameter): Compute the Bore Diameter based on the engine displacement, number of cylinders and the stroke length.
• Bore Stroke Ratio: Compute the Bore Stroke Ratio based on the diameter of the bore and the length of the stroke.
• Compression Ratio: Compute the Combustion Ratio base on the minimum and maximum displacements of the cylinder at the beginning (1-Induction) and compressed (3-Power) portions of the combustion cycle (see animation)
• Displacement Ratio: Compute the Displacement Ratio based on the volumes at the beginning and end of the stroke.
• Rod Length Stroke Ratio: Compute the Rod and Stroke Length Ratio base on the two lengths.
• Stroke (length): Compute the Stroke Length based on the total engine displacement, number of cylinders and the bore.
• VOLUMES:
• Total Engine Displacement: Compute the Total Volume (displacement) of a Combustion Engine based on the bore, stroke and number of cylinders.
• Engine Cylinder Overbore Volume: Compute the Volume (displacement) of an Engine with an Overbore based on the stroke, bore, overbore and number of cylinders.
• Rotary Engine Equivalent Displacement: Compute the Equivalent Volume of a Rotary Engine based on the swept volume and number of pistons.
• Compression Volume (V2): Compute the Compressed Volume of a Cylinder when the piston is at the end of the stroke and the chamber is at its smallest (and most compressed) volume, based on the chamber, deck, crevice, chamfer, gasket, valve relief and dome/dish volumes.  This is the second volume (V2) in the Compression Ratio calculation.
• Gasket Volume: Compute the Volume of a Gasket based on the inner and outer diameters and the gasket's thickness.
• Deck Volume: Compute the Volume of a Cylinder Deck based on the deck height and the bore.
• Crevice Volume: Compute the Volume of a Cylinder Crevice based on the piston diameter, cylinder bore and the crevice height.
• Chamfer Volume: Compute the Volume of a Cylinder Chamfer based on the cylinder diameter and the chamfer height and width.
• SPEEDS AND RPMS:
• Piston Speed: Piston Speed (mean) based on stroke length and RPMs.
• Max Piston Speed: Max Piston Speed based on stroke length and RPMs
• RPMs: RPMs based on desired piston speed and stroke length.
