there are a few reasons for engines knocking......... - bad type of fuel
- higher gear ratio at slower speeds
if your engine knocks when you start it up then you have probably got a bad or dirty fuel in your car... change the filters or just get away with using it and change your petrol station if the engine knocking happens during driving then its because you are putting more gas on at lower speeds and higher gear ratios...you just need to lower your gear. say change from gear 3 to gear 2 and try increasing the gas gradually and slowly and the knocking should go away....
knocking noise
If you have knocking from the engine and smoke from the exhaust then you have far more problems than the car just not starting. Sick professional help immediately.
engine knocking hard,and shaking a bit
Either get higher octane fuel, or retard the timing. That is about the only thing that will help
NO. A knocking noise in the engine is a problem in the engine.
Lead was added to gasoline to inexpensively increase octane ratings and to also help reduce engine knocking.Increasing octane and reduce engine knocking are exactly the same thing, as the test method to measure octane of a fuel is to see when a standard engine begins knocking. The higher compression ratio the standard test engine can be operated at without knocking, the higher the octane of the fuel being tested.
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
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.
