tændingsrækkefølger

Tændingsrækkefølgen refers to the specific order in which the spark plugs in an internal combustion engine ignite the fuel-air mixture in each cylinder. This sequence is crucial for the smooth and efficient operation of the engine. The firing order is determined by the engine's design, particularly the configuration of the crankshaft and camshaft. For example, in a four-cylinder inline engine, a common tændingsrækkefølge is 1-3-4-2. This means cylinder 1 fires, then cylinder 3, followed by cylinder 4, and finally cylinder 2.

The purpose of a specific firing order is to balance the forces generated by the combustion process. By staggering the ignition events, engineers aim to minimize vibrations and ensure that the engine runs as smoothly as possible. An incorrect tændingsrækkefølge can lead to rough running, loss of power, increased fuel consumption, and potential engine damage. In engines with more cylinders, such as V6, V8, or even 12-cylinder engines, the firing orders become more complex but still follow the principle of balanced forces.

The tændingsrækkefølge is typically specified by the engine manufacturer and is essential information for mechanics when performing maintenance or repairs, especially when working on the ignition system. Understanding this sequence is fundamental to comprehending how an engine functions and how its components interact to produce power.
