Njira yopangira njerwa yoyatsira moto ndi yosiyana ndi ya zinthu wamba wandiweyani. Pali njira zambiri, monga njira yowonjezera yowotcha, njira ya thovu, njira yamankhwala ndi njira ya porous, etc.
1) Njira yowonjezera yowotcha ndikuwonjezera zinthu zoyaka zomwe zimatha kuyaka, monga ufa wamakala, utuchi, ndi zina zambiri, kudongo lomwe limagwiritsidwa ntchito popanga njerwa zomwe zimatha kupanga ma pores ena munjerwa pambuyo kuwombera.
2) Njira ya thovu. Onjezani chopangira thovu, monga sopo wa rosin, mu dongo lopangira njerwa, ndipo pangani thovu pogwiritsa ntchito makina. Pambuyo powombera, zinthu za porous zitha kupezeka.
3) Njira ya mankhwala. Pogwiritsa ntchito mphamvu zamagetsi zomwe zimatha kupanga gasi moyenera, chinthu cha porous chimapezeka popanga njerwa. Nthawi zambiri kugwiritsa ntchito dolomite kapena periclase ndi gypsum ndi sulfuric acid ngati thovu wothandizira.
4) Porous zinthu njira. Gwiritsani ntchito zida zachilengedwe za diatomite kapena zopangira thovu zadongo, mipira ya aluminiyamu kapena zirconia yopanda kanthu ndi zida zina zopangira njerwa kuti mupange njerwa zoyaka moto.
Kugwiritsanjerwa yoyatsira moto yopepukandi otsika matenthedwe madutsidwe mphamvu pang'ono kutentha monga ng'anjo kapangidwe zipangizo akhoza kupulumutsa mafuta ndi kupititsa patsogolo ntchito ng'anjo kupanga bwino. Itha kuchepetsanso kulemera kwa ng'anjo yamoto, kufewetsa kapangidwe ka ng'anjo, kuwongolera zinthu zabwino, kuchepetsa kutentha kwa chilengedwe, ndikuwongolera magwiridwe antchito. Njerwa zoyatsira moto zopepuka zopepuka zimagwiritsidwa ntchito ngati zotsekera, zomangira zounikira.
