What Causes Incorrect Ignition Timing?

[LeNorah]

Incorrect ignition timing is caused by: misalignment during timing belt replacement or issues with the tensioner causing the timing belt to skip teeth. The timing belt is a crucial component of the engine's valve system, ensuring accurate intake and exhaust timing through its connection to the crankshaft and specific transmission ratio. Belts are used instead of gears for transmission due to their lower noise, minimal self-variation, and ease of compensation. In gasoline engines, ignition timing is key to fuel combustion efficiency. Proper ignition timing promotes complete fuel combustion, maximizes thermal efficiency, ensures normal engine power output for maximum effective power, and prevents a series of faults such as piston top burning, ring breakage, cylinder scoring, and power loss caused by engine knocking.
