What is the normal range for ignition advance angle?

[SanLeila]

The normal range for ignition advance angle is between 6 and 12 degrees. More relevant information is as follows: 1. The ignition advance angle refers to the angle through which the crankshaft rotates from the moment of ignition until the piston reaches the top dead center of compression. This angle allows the engine to achieve better power performance, fuel economy, and emissions. To prevent power loss in the vehicle, it is recommended to set the ignition advance angle above 6 degrees, which is also the required rotational angle for starting the car. 2. An appropriate ignition advance angle can maximize the mechanical work done by the engine in each cycle. If the ignition advance angle is too large, detonation may occur; if it is too small, the engine temperature will rise. Factors affecting the ignition advance include engine speed and the combustion speed of the air-fuel mixture.
