What is the effect of ignition advance angle on the engine?
1 Answers
The effect of ignition advance angle on the engine is: 1. An excessively large ignition advance angle will reduce the engine's power, increase fuel consumption, and cause poor idle performance; 2. An excessively small ignition advance angle may result in backfiring in the exhaust pipe and intake port backfire phenomenon. The control methods of ignition advance angle include: 1. Initial ignition advance angle; 2. Knock control; 3. Knock control methods. The ignition advance angle refers to the spark plug firing in advance before the engine piston reaches the compression top dead center. It is the angle through which the crankshaft rotates from the moment the spark plug fires until the piston reaches the compression top dead center.
