LPG (mafuta amadzimadzi amafuta)
LPG ndi chisakanizo chamadzimadzi cha propane, butane ndi zowonjezera zina, zomwe zimapangidwa panthawi yokonza mafuta amafuta. Poyambirira, ilibe mtundu, kukoma ndi kununkhira, choncho, fungo limawonjezeredwa kusakaniza - fungo (chinthu chokhala ndi fungo). LPG ndi yopanda poizoni, koma simalowa mu mpweya ndipo imakhala ndi poizoni wochepa. Pamene mpweya uli ndi mpweya, umakhala wolemera kuposa mpweya, ndipo mumadzimadzi umakhala wopepuka kuposa madzi. Chifukwa chake, magalimoto a LPG sayenera kusiyidwa m'magalasi apansi panthaka, chifukwa ngati kutayikira, LPG imakhazikika m'malo otsika kwambiri ndikuchotsa mpweya wopumira.
LPG imapangidwa pakupanga mafuta amafuta. Imadzilowetsa pozizira kapena kukanikiza kuti ichepetse kutsika kwake 260. LPG imagwiritsidwa ntchito ngati yotsika mtengo m'malo mwa mafuta chifukwa zida zake ndizofanana. Ndi mafuta abwino kwambiri okhala ndi octane ozungulira 101-111. M'mikhalidwe yathu, zomwe zimatchedwa nyengo yachisanu ya LPG osakaniza (60% P ndi 40% B) ndi chisakanizo cha LPG chachilimwe (40% P ndi 60% B), i.e. Kusintha magawano ofanana a propane ndi butane.

Kuti mumveke bwino (calorific value, calorific value, etc.), "Theoretical Equivalence Coefficient" imafotokozedwa ngati kuchuluka kwa mafuta okhala ndi mphamvu inayake yofanana ndi mtengo wamafuta wa calorific. Kenako "chiyerekezo chenicheni chofanana" pakati pamomwe amagwiritsira ntchito injini chatsimikizika, chomwe titha kufananiza bwino kwambiri.

Tiyeni titenge galimoto yomwe ili ndi mtunda wamagesi pafupifupi 7 malita. Kenako (poganizira kaphatikizidwe ka chisakanizo cha chilimwe ndi kufanana koyerekeza, timapeza chilinganizo:
(mafuta ogwiritsa ntchito * (40% propane ofanana ndi 1,27 + 60% butane ofanana ndi 1,11)) = Kugwiritsa ntchito LPG
7 * (0,4 * 1,27 + 0,6 * 1,11) = 7 * 1,174 = 8,218 l / 100 km nthawi yotentha
7 * (0,6 * 1,27 + 0,4 * 1,11) = 7 * 1,206 = 8,442 l / 100 km m'nyengo yozizira
Chifukwa chake, kusiyana kwa nyengo zomwezo kudzakhala 0,224/ 100 km. Pakadali pano, awa onse ndi ziwerengero zongoyerekeza, koma amafotokoza kuti kumwa kumakula kokha chifukwa chakuzizira. Zoonadi, amakhalanso ndi udindo wowonjezeranso kugwiritsira ntchito - matayala achisanu, nyengo yozizira imayamba, kuunikira kochulukirapo, matalala pamsewu, mwinanso kutsika kwa mwendo, ndi zina zotero.
