Why does the engine need timing alignment?

[McAriel]

The reason the engine needs timing alignment is that the timing system is a crucial component of the engine's valve train. By connecting to the crankshaft and maintaining a specific gear ratio, it ensures the precise timing of the engine's intake and exhaust cycles. The function of the timing system: When the engine is running, the piston's stroke, the opening and closing of the valves, and the ignition sequence must remain "synchronized" under the coordination of the timing system. Through the engine's timing mechanism, each cylinder achieves the perfect moment where the piston reaches top dead center, the valves close precisely, and the spark plug fires at the right instant. Components of the timing system: It typically consists of the timing belt, tensioner pulley, tensioner, water pump, and other related accessories.
