1 Answers
BMW cylinder numbering arrangement: Starting from the front of the car on the left side are cylinders 1234, and on the right side are 5678. That is, the side with the oil filler cap is cylinders 1234, and the other end is 5678. Definition of cylinder count: Cylinder count refers to the number of cylinders in an engine. Common cylinder counts for automotive engines are 3, 4, 6, 8, 10, and 12 cylinders. Engines with displacement below 1 liter typically use three cylinders, 1-2.5 liters generally use four cylinders, around 3 liters usually have six cylinders, around 4 liters have eight cylinders, and above 5.5 liters use twelve cylinders. Relationship between cylinder count and displacement: Generally speaking, with the same cylinder bore diameter, more cylinders mean larger displacement and higher power output. With the same displacement, more cylinders allow for smaller bore diameters, enabling higher engine speeds and thus achieving greater power output.
