Tambaya: Yana throttle body mai ƙarfi zai sanya wani ƙarfi?

Amsa: Ba a matsayin hukuma a cikin engine na stock. Throttle body mai ƙarfi da yawa zai haifar da karamin tashin airflow a lokacin da aka yi amfani da shi a yawan rmp kuma zai iya haifar da karamin idlen. Wani ƙarfi zai samu ne kuma a lokacin da aka yi amfani da wani mod mai ƙarfi kamar cams ko forced induction wanda ya nuna yawa da airflow. Lamba na bolt-on alone ba zai iya canza dyno a cikin stock EFI map. Kammala bore da build, kuma koyi yadda za a iya canza drivability, ba horsepower.

Tambaya: Yana cable throttle body zai iya canza drive-by-wire?

Amsa: Ba tare da kafin. Mota na drive-by-wire ta bukata kontroli na motor da sensori na gaba daya; amma unit na kabilu ba ta karuwa wadannan. ECU zai nuna alama na kuskure da zai ci gaba da ‘limp mode’. A cikin sauya, yana bukata sauya na kabilu, sauya na pedal, da sauya na firmware wanda ba ta kasance a kan throttle body kuma. Idan ba dukkanin system an sauyawa ta hanyar rarrabuwa, koma a yi amfani da type na ETC wanda manufacturer ya bayyana shi don kula da safe da legal.

Tambaya: Wace abu ne ya zama sabonin ‘throttle body limp mode’?

Amsa: Yadda yake a matsayin farko da yadda yake a watsi na plate ya zama sabonin ‘safety limit’. Kusura na carbon, motor mai tsoro, ko TPS sensor wanda ya faru daga kari ya zama sabonin ‘out of tolerance’ na throttle body. ECU ya ci plate don kula da engine. A cikin sauya, a rubuta, ko a sauya unit din zai iya sauya aiki daidai. Ku sanya codes na kuskure kafin; kada ku sauya su kuma ku ji kyau.

Tambaya: Yaya za a rubuta throttle body da safe?

Amsu: Amfi kuma ETC cleaner da yin gaba mai kyau; ba za a yi karin kari ne ko kari na plate. Throttle body wanda yana da carbon a kudura ta hanyar yin gaba ya zama mai tsoro a yin gaba da yin gaba ta hanyar yin gaba, kuma ya zama mai tsoro a yin gaba.

Kimiyya mai tsoro ko alatun da suka dace suka taka kudura da suka raba sensor.

Tambaya: Sensor suna bukata in samu kamar yadda suka dace a lokacin yin kari?

Amsu: Ee. TPS slope da redundancy type suka dace da ECU map. Throttle body wanda yana da sensor mara dace ya bayyana bayani mai tsoro a cikin airflow kuma ya shiga faults. OEM ko aftermarket units wanda suka dace suna da curve da connector dace. Tabbata part number da, idan yake muna iya, sensor spec.

Tambaya: Yana kuma emissions compliance yana dace da throttle body?

Amsa: Ya zama. Kwallon tashin da ba a sanya shari ya zama kamar yadda ya kamata ko ya kashe tsarin da ke bayyana abin da ke aiki (closed-loop trim) kuma zai iya gudan kafin amfani da OBD ko test na gas.
