Number of pistons for 6 cylinder four stroke gasoline engine running at 2200 rpm:
A
24
B
6
C
91.67
D
NOTA
Explanation: 

Detailed explanation-1: -Four Stroke Cycle Engines. A four-stroke cycle engine is an internal combustion engine that utilizes four distinct piston strokes (intake, compression, power, and exhaust) to complete one operating cycle. The piston make two complete passes in the cylinder to complete one operating cycle.

Detailed explanation-2: -at 2000 rpm in a 4-stroke engine there are 1000 cycles/min or 16.67 cycles/s.

Detailed explanation-3: -By the way, the mean piston speed for this 1-cylinder engine at 6, 000 rpm is 3, 000 fpm, and the maximum piston speed (using our previous formula) is 4, 712 fpm.

Detailed explanation-4: -At 6000RPM the piston will do 12000strokes. This does not matter if it is a two stroke or four stroke engine. If you have more cylinders than one then multiply the number above by the number of cylinders. If you’re counting up and down strokes, 6, 000rpm = 12, 000 strokes.
