The only type of current used by automobiles is dc current although the alternator produces ac current which is converted to dc by rectifiers built into the alternator. Even the alternator is controlled by dc current though through the use of a voltage regulator which limits the amount of negative dc sent to the stator and positive dc current sent to the rotor of the alternator which limits the EMF.
The typical automobile operates on DC (Direct Current) even though the typical alternator produces AC (Alternating Current) which is then converted to DC.
You can block AC current by using a filter with a pass-band that is outside the frequency of the AC current.

No. Batteries can only produce dc current which can further be converted to AC using inverters.
AC current can be transmitted with less loss
Current filtering
AC current (alternating current) like in a wall outlet
Yes, the current used by a typical light fixture in a house is alternating current (AC). This type of current is commonly used for household electrical systems as it can easily be converted to different voltages using transformers.
Yes, the AC current can be amplified by using Step-down transformers, but one problem is the AC voltage will decrease with Step-down transformer.
The suffix "-tor" turns the word into an "agent noun" (for Latin and other Italic languages). Agent nouns designate a person/thing that perform a particular action. In this case, the action taking place is the altering of electrical current (AC); that which alternates the current is the alternator.
