Thus, the engine of your car burns the right amount of air/fuel mixture for the smooth combustion process. During acceleration, many times you will hear some metal knocking noise from the Porsche Cayenne that gets louder and faster when you speed up the car. Apparently, the knocking noise can be more noticeable when you are running the engine under a heavy load. Go through the following slide to know about the causes behind your Porsche Cayenne producing a knocking noise when you accelerate.

1. What Causes A
Knocking Noise When
You Accelerate Your
Porsche Cayenne in
Cary?

2. For the smooth
combustion process,
the engine burns the
right amount of air/fuel
mixture in the car.

3. During acceleration,
many times you will
hear a knocking noise
while driving the
Porsche Cayenne.

4. In general terms, when
the fuel in the tank is
igniting at the wrong
time, it will cause a
knocking sound.

5. Typically, the knocking
noise can be more
noticeable when you
are running the engine
under a heavy load.

6. The following points define the causes
behind your Porsche Cayenne
producing a knocking noise when you
accelerate.

7. Lean air/fuel mixture

8. Lean air/fuel mixture
indicates that the
amount of fuel in the
combustion chamber is
lower as compared to
the air.

9. Due to the lack of fuel
in each cylinder, the
engine produces some
detonations and causes
a knocking noise when
you accelerate.

10. Too low fuel octane

11. Thus, the engine of all
the vehicles is designed
in such a way as to run
on a certain number of
octane.

12. Using low-octane fuel
can reduce engine
performance and
produce a knocking noise
during acceleration.

13. Bad spark plugs

14. Spark plug can provide
the spark to the engine
for igniting the right
mixture of air/fuel in
the combustion
chamber.

15. If it is failed, then it could
cause a problem within
the combustion process
that may lead to a
knocking noise.

16. Worn out bearing

17. Engine bearing of the
car are keeping the
piston moving properly
and opens and closing
the intake valve
smoothly.

18. When the bearing of the
Porsche is failed, then
the engine is making a
knocking noise.

19. Bad knock sensor

20. Knock sensors can
monitor the noises
produced by the engine
and regulate the fuel
combustion time of the
engine.

21. When the sensor is
failed, the check engine
might flip up and
produce a knocking noise
from the engine.

22. Conclusion

23. Drive your Porsche with
an engine knocking
noise during
acceleration may cause
major engine damage.

24. If the engine of your
Porsche Cayenne is
making a knocking noise
when accelerating, then
get it fixed immediately.
