* Dwell angle is a term used in ignition systems with points or breaker systems. It refers to the amount of time the points are closed, allowing current to flow to the ignition coil and build up a magnetic field.
* Modern 3-cylinder engines typically use electronic ignition systems, eliminating the need for points. These systems use sensors and electronic control units to precisely time the spark plug firing.
Instead of dwell angle, we consider these factors for 3-cylinder engine ignition timing:
* Firing order: The sequence in which cylinders fire. In a 3-cylinder engine, a common firing order is 1-2-3.
* Ignition timing: The precise point in the engine cycle when the spark plug fires, measured in degrees before top dead center (BTDC).
* Spark duration: The length of time the spark plug is energized.
Understanding how these factors work together is important for engine performance, fuel economy, and emissions.
If you have a specific question about ignition timing in a 3-cylinder engine, please provide more context, and I'll be happy to help.
