Wannan lambar ita ce lambar watsawa gaba ɗaya. Ana ɗaukarsa ta duniya kamar yadda ta shafi duk kera da ƙirar abin hawa (1996 da sabuwa), kodayake takamaiman matakan gyara na iya bambanta kaɗan dangane da ƙirar.

Akwai kayayyaki daban-daban na tsarin sake zagayowar iskar gas, amma duk suna aiki iri ɗaya. Ƙarƙashin Gas Recirculation Valve wani bawul ne da PCM (Powertrain Control Module) ke sarrafawa wanda ke ba da damar auna yawan iskar iskar gas don komawa cikin silinda don konewa tare da cakuda iska / man fetur.

Ba a buƙatar EGR a lokacin fara sanyi ko lokacin bacci. EGR yana samun kuzari a ƙarƙashin wasu sharuɗɗa, kamar lokacin farawa ko ragi. Ana ba da iskar gas ɗin da aka ƙera a ƙarƙashin wasu sharuɗɗa, kamar juzu'i na juzu'i ko raguwa, gwargwadon zafin injin da kaya, da dai sauransu. . Idan ya cancanta, ana kunna bawul ɗin, yana ba da damar iskar gas ta shiga cikin silinda.
