What is Ignition Advance Angle?
1 Answers
From the moment of ignition until the piston reaches the top dead center of compression, the angle through which the crankshaft rotates during this period is called the ignition advance angle. Adjusting the ignition advance angle: Remove the secondary chamber vacuum hose from the vacuum advance compensation device and block the two ports connected to the hose. Run the engine at idle speed, then use a timing light to check the ignition advance angle. Verifying the ignition advance angle: Start the engine and repeatedly press the accelerator pedal. If the engine feels powerful and there are no abnormal knocking sounds, it indicates that the ignition advance angle is appropriate. A timing light can also be used to confirm the ignition advance angle. As the engine speed increases, the timing mark will move in the direction of increasing ignition advance angle.
