NO. A knocking noise in the engine is a problem in the engine.
Engine knocking can be caused by numerous things. Having the incorrect spark plugs, carbon deposits on the cylinder walls, and being low on engine oil may all cause a knocking sound.
if your engine is knocking that means you need oil. go get an oil change or add a quart asap or the engine will burn out
In SI engine knock occur due to spontaneous ignition of end gases , as propagating flame compresses the mixture causes high temp & pressure reaction take place in end gases that burns rapidly with high pressure peak called knock. Where as in CI engine knocking or detonation occur due autoignition fuel & air not mixed homogeneous prior to combustion.pressure peaks of knock come before Top Dead Center(TDC) in CI engine where as in SI engine it comes after the TDC.
Detonation involves a supersonic exothermic. Knocking in a engine is spark-ignition internal combustion.
if the engine is knocking really loud you probably need to overhaul the entire engine or get a new or used engine because loud knocking is not good
When the fuel in an engine cylinder ignites prematurely or unevenly to cause power fluctuations and a "knocking" sound. usually occurs when an engine is very how or improperly timed.
