Selling your car in Dubai because you think it sounds funny? Maybe your modern car is making sounds for other reasons, but a vintage engine would probably be experiencing something known as knocking. It is a term all car owners should know.

Science behind it: The incorrect composition of air and fuel inside your car’s cylinder can cause engine knocking to occur. This uneven burning of fuel creates the phenomenon of fuel burning in larger amounts as opposed to smaller segments. The chemistry of fuel burning is such that when one pocket of fuel burns it causes a chain reaction and burns neighboring pocket until all the fuel is burned in that stroke. When these smaller segments of fuel do not burn evenly they cause shocking sensations against the cylinder wall which creates the knocking sound.

Common Causes: Fuel in your car with low octane rating can cause this problem. The anti-knock index can help you determine the octane rating of gasoline. Other reasons for engine knocking could be carbon deposits on the walls of the cylinder or the use of incorrect spark plugs.

Solution: Engine knocking can be fixed by using  higher octane fuels. Or if your car has incorrect spark plugs then check on the specific part number of your spark plug as each is designed to run at a given range. Check the exact requirement of your car specific spark plug and get them installed. Reduce carbon build up by using an unleaded gasoline and a good quality fuel stabilizer. These maintenance steps are needed regularly for your car.

Selling your car in Dubai, would be a much easier task if you take care of it and make sure the engine is not making any knocking sounds. If you still find it difficult to sell your car in Dubai then allow CarSwitch to take up the job.
