How should Audi start?

The traditional ignition method of 1 is that the crankshaft drives the distributor shaft to rotate, and the cam on the distributor shaft rotates to make the primary contact of the ignition coil on and off, resulting in high voltage electricity. At this time, the spark plug will emit an electric spark to ignite the gas in the room, and the engine will enter the working state. 2 Electronic Ignition Mode The electronic ignition mode is different from the traditional ignition mode because the engine ignition is controlled by an electronic control device. The driving computer judges the working state of the engine through the engine speed sensor, intake pipe vacuum sensor (engine load sensor), throttle position sensor and crankshaft position sensor to create the best ignition time.
