Zomera zosakaniza phula zimapangidwa ndi machitidwe ambiri, omwe ali ndi ntchito zosiyanasiyana. Dongosolo loyaka moto ndilofunika kwambiri pakugwiritsa ntchito zida ndipo limakhudza kwambiri magwiridwe antchito ndi chitetezo cha zida. Masiku ano, matekinoloje ena akunja nthawi zambiri amagwiritsa ntchito makina oyatsira gasi, koma machitidwewa ndi okwera mtengo ndipo sali oyenera makampani ena.

Kwa China, zida zoyatsira zomwe zimagwiritsidwa ntchito nthawi zambiri zimatha kugawidwa m'mitundu itatu, monga malasha, mafuta ndi gasi. Kenaka, ponena za dongosololi, pali mavuto ambiri akuluakulu, makamaka kuphatikizapo kuti phulusa lomwe lili mu ufa wa malasha ndi chinthu chosayaka. Kukhudzidwa ndi kutentha kwa chomera chosakaniza phula, phulusa lalikulu limalowa muzitsulo za asphalt. Komanso, phulusa ndi acidic, lomwe lidzachepetsa mwachindunji kusakaniza kwa asphalt, zomwe sizingatsimikizire moyo wautumiki wa mankhwala a asphalt. Panthawi imodzimodziyo, ufa wa malasha umayaka pang'onopang'ono, choncho zimakhala zovuta kuti ziwotche m'kanthawi kochepa, zomwe zimapangitsa kuti mafuta azikhala ochepa komanso kugwiritsa ntchito mphamvu.
Osati kokha, ngati malasha amagwiritsidwa ntchito ngati mafuta, kulondola kwapangidwe komwe kungapezeke pazida zachikhalidwe zomwe zimagwiritsidwa ntchito pokonzekera ndizochepa, zomwe zimachepetsa mwachindunji kupanga kulondola kwa osakaniza. Komanso, kuyaka kwa ufa wa malasha muzomera zosakaniza phula kumafuna chipinda chachikulu choyaka moto, ndipo zida zokanira m'chipinda choyaka ndi zida zosatetezeka, zomwe zimafunikira kuyang'aniridwa ndikusinthidwa nthawi zonse, ndipo mtengo wokonza ndi wokwera kwambiri.
Ndiye, ngati gasi atagwiritsidwa ntchito ngati zopangira, kuchuluka kwa kugwiritsidwa ntchito kumatha kupezeka. Dongosolo loyatsirali ndi lofulumira kwambiri ndipo lingapulumutse nthawi yochuluka. Komabe, njira yoyaka moto yamafakitale osakanikirana ndi phula omwe amawotchedwa ndi gasi alinso ndi zolephera zambiri. Iyenera kulumikizidwa ku payipi ya gasi yachilengedwe, yomwe si yoyenera pamikhalidwe yomwe imayenera kukhala yoyenda kapena nthawi zambiri imayenera kusamutsidwa. Komanso, ngati payipi ya gasi ili kutali, zidzawononga ndalama zambiri kukhazikitsa ma valve ndi kuyala mapaipi ndi zida zina zothandizira.
Ndiye, bwanji za njira yoyaka moto yomwe imagwiritsa ntchito mafuta ngati mafuta? Dongosololi silingangopulumutsa ndalama zopangira, komanso zimapangitsa kuti zikhale zosavuta kuwongolera kutentha kwamafuta. Dongosolo la kuyaka kwa zomera zosakaniza phula lopangidwa ndi mafuta amafuta limakhala ndi phindu pazachuma, ndipo limathanso kupeza mphamvu zoyatsira zoyenerera powongolera kuchuluka kwamafuta amafuta.
