Are the number of pistons equal to number of number of cylinders?
Is there any situation where the number of pistons might not be equal to the number of cylinders in a car engine?
It is rare, but there are some engines that have two pistons sharing one cylinder, such as the V-twin engine in some motorcycles. There are also engines that have more than one piston per cylinder, such as the Wankel rotary engine.
