Early Detection and Troubleshooting of the Causes of Engine Knocking
The combustion is a controlled explosion that is used to set the engine in motion. Knocking occurs when an unintentional second combustion takes place alongside the first. This results in pressure spikes that put a strain on the engine. This can damage the pistons, connecting rods, and crankshaft. To prevent damage, the engine control system intervenes. Causes of engine knocking can include an incorrectly set ignition timing, hot components inside the combustion chamber, or deposits in the intake system. In the case of deposits, the affected parts must be cleaned thoroughly, and the source of contamination must be located.
In the tenth episode of the MWM Service Tutorial series “Do it the smart way”, Kevin Kolbe offers helpful tips on how to detect and fix engine knocking at an early stage.
The issue of knocking combustion is complex, and the causes are manifold. The more you know about knocking combustion, the sooner you can take action. If you have any maintenance issues or questions, the MWM Service will be happy to assist you.
