How to Control the Ignition Advance Angle?

[DiKate]

Optimal ignition advance angle not only ensures the engine's power and fuel economy reach their best, but also minimizes the emission of harmful substances in the exhaust. The specific control methods are as follows: 1. Open-loop control of ignition advance angle. Open-loop control is when the electronic control unit extracts the corresponding basic ignition angle from its internal data based on the engine operating conditions provided by relevant sensors. 2. Closed-loop control of ignition advance angle. Closed-loop control can continuously monitor the engine's relevant working conditions, such as whether the engine is vibrating or the idle speed is stable, while controlling the ignition advance angle.
