Engine Geometry: Swept Volume and Compression Ratio

Engine Geometry: Swept Volume and Compression Ratio

Original quantitative learning practice in English. All 24 questions are included. Four supplied cases exercise six related calculation targets; they form one topic, not four separate tests. Every question includes the complete initial data. Use the stated model and retain intermediate precision. Choose one answer. Learning target: 20/24, not an official pass mark. This bank covers the calculation topic in its title; it is not a complete professional examination, design approval or operating instruction.

An ideal cylinder has bore 78 mm and stroke 70 mm. There are 2 identical cylinders. Clearance volume per cylinder is 36 cm³. Use π=3.1416 and compression ratio=(swept+clearance)/clearance. Ignore tolerances. This is a geometric model, not an engine modification specification. Calculate the volume per cylinder at the larger-volume endpoint in cm³. Keep intermediate values unrounded; round the final result to four decimal places if necessary.
