Da farko, Duk wani kwaikwaiyo na kwarara iska ta turbocharger kwampreso.
Kamar yadda muka sani, an yi amfani da compressors a matsayin ingantacciyar hanya don inganta aiki da rage fitar da injunan diesel.

Abu na biyu, tsarin sanyaya ruwa na turbocharger.
An gwada ƙara yawan ƙoƙarin da ake yi don inganta tsarin sanyaya don haɓaka fitarwa ta hanyar yin amfani da ƙarar aiki mai tsanani.
