A yayin aikin kera mota, injiniyoyi ba kawai suke tunanin aiwatar da sabuwar fasahar zamani ba, fitowar zamani da amincin farko. Injinan kona ciki na yau suna ƙoƙarin yin ƙasa da samun ƙwarewa sosai. Gabatar da supercharger na inji ɗayan waɗannan hanyoyi ne - don “matse” iyakar, ko da daga ƙaramin injin 3-cylinder.

Menene kwampreso na injiniya, yadda yake aiki da aiki, menene fa'idodi da rashin amfani - zamuyi magana game da wannan gaba.

Menene supercharger na inji

Mai injin busa wani inji ne wanda yake bayar da iska da karfi a matsin lamba don kara yawan cakuda mai-iska. Ana motsa kwampreso ne ta juyawa na jujjuyawar kwanya, a matsayin mai doka, ana amfani da na'urar ta hanyar bel. Airarfafa iska tare da turbocharger na injiniya yana ba da ƙarin 30-50% na ƙarfin da aka ƙayyade (ba tare da damfara ba).
