Yes.
1. The mixture is too thick: The mixture is too thick, which will prevent the mixture from burning completely. After the exhaust valve is discharged, the exhaust manifold will ignite again when encountering high temperature. causing gunshots.
2. Intermittent Spark Plug Ignition: When the spark plug fire is weak or misfires, the unignited combustible mixture enters the exhaust pipe and encounters the exhaust gases at high temperature and high pressure evacuated from the next combustion cycle. , and ignites and causes the cannon to fire.
The reasons why BMW 5 Series ignition coil failure causes high voltage in the generator are:
1. The external environment temperature is high and the temperature is too high, causing the ignition coil to overheat.
2. The engine is overheating.
3. The generator regulation voltage is too high.
4. The ignition coil may not match the engine.
