Cars are machines and like every other machine, they also encounter a fair share of issues throughout their life span. Generally, few signs are given by the car to alert the driver about any impending issues and one such sign that is commonly associated with problems is the knocking noise coming from the engine under the hood. The knocking sound indicates mechanical problems of the car. Go through the slide to know the issues related with the knocking noise in the car.

1. Issues Related With the Knocking Noise in Car

2. Many times the engine
will produce strange
noises which are coming
from under the hood and
that should be difficult to
diagnose.

3. The knocking sound is
the most typical one
which indicates the
mechanical problems of
the car and needs to be
diagnosed and fixed by
the mechanic correctly.

4. The knocking sound also
occurs in the car when
the air and fuel mixture is
incorrect and causes the
fuel to burn in uneven
pockets rather than the
uniform bursts.

5. If you left it untreated,
then it will damage the
piston and cylinder wall.
The knocking sound also
causes due to the lack of
lubrication in the upper
cylinder head area.

6. The following points help
you to recognize the
knocking noise issues in
your car.

7. Low octane rating
fuel

8. If you are putting the fuel
in your car which octane
rating is low, then it will
create a knocking noise in
your car.

9. The octane rating
generally refers to
measure the fuel's ability
to resist the premature
detonation of the air-fuel
mixture in the engine.

10. Then the combustion
causes the knocking
sound in your car. To
prevent these issues use
the gasoline which has
octane fuel rating as per
manufacturers
recommendation.

11. The octane booster of
the car can be purchased
from an auto part store
to restore the proper
octane rating and stop
the knocking.

12. Wrong spark plug

13. If you are not using the
recommended spark plug
recommended by the
manufacturer, then it will
cause knocking sound in
your car.

14. The spark plug has a
certain heat range that
can withdraw those heats
from the combustion
chamber.

15. The spark plug gap refers
to the place where the
spark plug ignites the
mixture of air and fuel to
power up the car.

16. In other hands, when the
spark plug gap is too
wide, then the engine
also causes the knocking
sound due to the spark
stopped firing or misfire
rapidly.

17. Carbon deposits

18. The fuel of the car need a
carbon cleaning
detergent to clean it, but
the thing is they unable
to prevent the carbon
deposits from forming.

19. The gasoline and diesel
are made up of multiple
carbon molecules, so the
residuals of carbon will
form the valves, spark
plugs and other
components in the
combustion process.

20. When the fuel mixes the
oxygen, it is burned. It
can reduce the amount of
volume inside the
cylinder and increase the
compression.

21. By using the fuel injector
cleaner, you can clean the
carbon deposits on the
engine components and
resolve the issues.

22. Conclusion

23. Resolving the engine
knocking problems of
your car is simple and
your car owners can also
easily resolve it.

24. If you unable to do it,
then consult with a
professional technician to
diagnose the sources of
knocking noise and
perform the necessary
repairs of the car.
