Seti ya jenereta ya gasi imapangidwa ndi injini ya gasi, jenereta, kabati yowongolera ndi zinthu zina. Injini ya gasi ndi jenereta zimayikidwa pa chassis imodzi yachitsulo. Chipangizochi chimagwiritsa ntchito gasi wachilengedwe, gasi wogwirizana ndi chitsime, gasi wa mgodi wa malasha, gasi wamadzi, gasi woyenga ndi wa mchira wa mankhwala, gasi wa biogas, gasi wa uvuni wa coke, gasi wa ng'anjo yoyaka ndi gasi wina woyaka ngati mafuta.
Imayamba mwachangu ndipo ili ndi ndalama zabwino. Makamaka chifukwa cha kufunika kwa moyo wabwino kwambiri m'mizinda, majenereta opangidwa ndi gasi akhala akugwiritsidwa ntchito kwambiri m'ma telecommunications, positi ofesi, mabanki, malaibulale, zipatala, mahotela ndi madipatimenti ena ngati magetsi othandizira. Phokoso lopangidwa ndi jenereta ya gasi nthawi zambiri limakhala 110 ~ 95 dB pansi pa momwe ntchito ya mgodi imayendera poyamba. Muyezo wa GB 3096-93 wa phokoso lachilengedwe m'mizinda uli ndi malamulo okhwima okhudza momwe phokoso lilili m'mizinda. M'madera a kalasi yachiwiri (malo okhala, amalonda ndi mafakitale osiyanasiyana), ndi 60 dB (a) masana ndi 50 dB (a) usiku; 55 dB (a) masana ndi 45 dB (a) usiku m'dera la kalasi yoyamba (malo okhala, chikhalidwe ndi maphunziro). Phokoso lopangidwa panthawi yogwira ntchito ya chipangizochi labweretsa kuipitsidwa kwakukulu kwa phokoso m'mizinda, lakhudza ntchito ya anthu ndi moyo wawo, ndipo lachepetsa kugwiritsa ntchito kwa majenereta opangidwa ndi gasi. Pepalali likupereka njira zingapo zowongolera kuti muchepetse phokoso la mayunitsi opanga gasi ndikulimbikitsa kufalikira ndi kugwiritsa ntchito mayunitsi opanga gasi.
Phokoso la injini ya gasi ndiye gwero lalikulu la phokoso la jenereta ya gasi. Phokoso la injini ya gasi lingagawidwe m'magulu awiri: phokoso la aerodynamic, phokoso la kuyaka, phokoso la makina, phokoso la utsi ndi phokoso la kugwedezeka. Phokoso la aerodynamic limaphatikizapo phokoso la kugwedezeka kwa mpweya lomwe limayambitsidwa ndi kulowa, kugwedezeka ndi kuzungulira kwa fan, komwe kumatumizidwa mwachindunji kumlengalenga. Kugwedezeka kwa mphamvu komwe kumapangidwa ndi kuyaka mu silinda kumadutsa pamutu wa silinda, ndipo phokoso lomwe limatuluka kuchokera mthupi limatchedwa phokoso la kuyaka; Kukhudza kwa pistoni pa silinda ndi phokoso la kugwedezeka komwe kumapangidwa ndi zinthu zosuntha monga valavu ndi dongosolo lopangira mpweya zimatchedwa phokoso la makina. Chipangizocho chikagwira ntchito, mpweya wa utsi umatuluka mu valavu yotulutsa mpweya mwachangu kwambiri, kulowa mu muffler motsatira manifold ya utsi, ndipo pamapeto pake umatulutsidwa mumlengalenga kuchokera ku tailpipe. Phokoso la utsi ndiye phokoso lalikulu kwambiri la injini, lomwe nthawi zambiri limakhala pafupifupi 15 dB (a) kuposa la wolandila injini, kutsatiridwa ndi phokoso la kuyaka, phokoso la makina, phokoso la fan ndi phokoso la intake.
