Audi A6L2.4 cylinder arrangement sequence and ignition sequence, please tell me, thank you.

Cylinder arrangement sequence: V-shaped arrangement, with 123 from front to back on the left and 456 from front to back on the right.

Order: 153624 as long as it is in-line six cylinders.

Cylinder 4 can't ignite at this time, only cylinders 2 and 3 are at the top dead center, so only cylinders 2 or 3 can ignite; When cylinder 2 is ignited, cylinder 3 cannot ignite, and only 1 cylinder or cylinder 4 can ignite; Therefore, the ignition sequence of a four-cylinder engine is 1342 instead of 1234 (because cylinders 2 and 3 cannot ignite adjacent to each other).

Extended data:

Ignition sequence principle:

Ignition sequence is a machine that can convert one form of energy into another more useful energy. It is mainly composed of cylinder block, crankcase, cylinder head and cylinder gasket.

Generally, chemical energy is converted into mechanical energy. Sometimes engines are suitable for both power generation devices and complete machines including power devices, such as gasoline engines and aero-engines. The main part of power is the cylinder, which is the power source of the whole car.
