Jockey after flameout, somebody can hear car bottom to have clack reputation, some car noise are quite big still, in summer particularly apparent, general noise returns to normal after 35 minutes, somebody still runs designedly 4S inn makes an inspection, is this the car has a problem? This is not the car has a problem, this is the sound that vent-pipe gives out. After what the car leaves became long, the temperature of vent-pipe will be very high, forehead can achieve 779 degrees, at this moment vent-pipe is to be in expand condition. Should jockey after flameout, vent-pipe no longer be heated, begin to cool, be in medicinal powder hot condition, the metal of vent-pipe can contract and sound at this moment, so this sound is metallic systole sound, it is normal, do not run to was checked in vain again. Somebody has heard this voice, somebody had not been heard, what average car attends a meeting became long ability appears, open 35 kilometers to jockey to appear not quite easily, because vent-pipe still is not very hot, what did not expand is too much, also won't contract give out noise, not be to drive every time so the metropolis after flameout is heard.
Cars of some turbine pressure boost contain delay time to come loose hot function, flameout hind also can hear the voice that fan rotates, this also is normal, the function of to protect turbine supercharger designed design. Besides, won't give out other sound after engine flameout, want flameout only, all equipment that use phone quit the job entirely, because cut off the power, mechanical component also quited the job certainly, although which component damaged, also won't sound is given out. So, the sound that after jockeying, appears is normal commonly, need not check maintenance, in travel if heard unusual voice, need seasonable examination.
As similar as this still have vent-pipe drop water, this also is not breakdown. Some people see vent-pipe drop water is serious, consider as a car which component slack, also be to hasten 4S inn goes checking. Actually this also is normal phenomenon, do not need to check. Gasoline burns completely generation is most is carbon dioxide and water, ordinary water is the formal eduction with vapor, if do not condense into little water,we also cannot see. At ordinary times we see, it is vapor when walking along minor details vent-pipe, because vent-pipe temperature is so not high, come up against vent-pipe wall to be able to condense into urine drop to adhere to above, accumulate more more form current finally to go out.
If can decide those who pour out of to the liquid on the ground is vent-pipe, do not need to make any inspections so, because although there is other liquid leak on the car, also won't in inpour vent-pipe, flow from vent-pipe. If drive see there is a liquid on the ground, do not know to come from where leakage, removed the car seeing a liquid is oil or water, if be water,be normal, if be oil criterion,need makes further examination. There is a liquid on the ground, if be to be among car rear the position, it is the water in vent-pipe commonly, if be in engine bottom, may be oily fluid is divulged, if opening air conditioning travel to pass, also may be air conditioning water.
