Ɗaya daga cikin mafi sauƙi hanyoyin ƙara ƙarfin injin shine cajin caji, wato, tilasta iska a cikin silinda. Daga cikin nau'ikan compressors daban-daban, mafi mashahuri shine turbocharger, wanda yawanci ana haɗa shi da injin dizal.
The turbocharger kunshi biyu rotors located a kan wannan shaft. Jujjuyawar na’urar rotor, da kuzarin iskar gas da ke barin injin, ya sa na’ura ta biyu ta jujjuya a lokaci guda, wanda ke tilasta iska a cikin injin. Don haka, ba a buƙatar ƙarin tushen makamashi don fitar da turbocharger.
A cikin kowane injin fistan, kusan kashi 70% na makamashin da ake samu daga konewar man fetur ba a yi amfani da shi ba a cikin yanayi tare da iskar gas. Turbocharger ba wai kawai inganta aikin injiniya ba, amma kuma yana ƙara yawan aiki.
Abin takaici, kamar yadda yakan faru a cikin fasaha, babu wani tsari mai kyau, don haka turbocharger na gargajiya yana da lahani. Da farko dai, ba shi da yuwuwar "canji mai laushi" a cikin haɓakar matsa lamba na silinda kuma yana nuna jinkirin amsawa don danna fedal gas. Ya ta'allaka ne da gaskiyar cewa ƙarfin injin baya ƙaruwa nan da nan bayan saurin latsawa akan feda na totur. Sai bayan ɗan lokaci injin ɗin ya ɗauki sauri da sauri. Waɗannan gazawar sun kasance sananne musamman a cikin injunan dizal na farko na gama gari. Wannan shine yadda aka ƙirƙira injin turbocharger na VTG tare da madaidaicin juzu'in juzu'i.
Yana aiki ta hanyar canza kusurwar injin turbine, ta yadda aikin turbocharger yana da kyau sosai har ma a ƙananan nauyin injin da ƙananan gudu. Bugu da ƙari, ya zama mai yiwuwa a daidaita matsi na haɓakawa da kyau.
A cikin injunan diesel na VTG, ba a sami tsaiko a cikin aiki ba, kuma karfin juyi yana da girma har ma da ƙarancin saurin injin, kuma ana ƙara ƙarfi.
