P14. What is spark plug carbonization ? Its a phenomenon through which the ignition end adhered coal causes electrical leaks that produce ignition failures.
|
||
|
|
As the coal is conducting of energy, the electric does not pass between the electrodes. It is lead through the coal provoking functioning problems and making it difficult the ignition. Carbonization
|
|
|
Isolation resistance depending on the voltage generated by the ignition coil
|
||
 |
While coal accumulates, spark plug isolation capacity disminishes and voltage requirement diminishes too causing ignition failure. | |
|
Causes that can provoke the carbonization in the sparkling plugs: The available voltage for the ignition diminishes proportionally to the decrease of the insulation resistance. In this condition the available voltage diminishes until provoking misfire. |

Solutions
|
||
| •
Air/fuel mixture (A/F) too rich - Incorrect carburator adjustment - Defective throttling system - Defective fuel injection system |
It is necessary to regulate the carburator, the throttling system and the fuel injection system. | ||
• Defective ignition system - Defective high tension wire connection |
It is necessary to fix the ignition system. | ||
|
|
It is necessary to ride the vehicle at a higher rotation for the combustion chamber to reach the ideal temperature. |
||
| • Spark plug too cold | Use an appropriate spark plug |
