LPG (yakasanganiswa peturu yegesi)
LPG musanganiswa wakanyoroveswa wepropane, butane uye zvimwe zvinowedzera, izvo zvinoumbwa panguva yekugadziriswa kwepetroleum feedstock. Mumamiriro ekutanga, haina ruvara, kuravira uye kunhuwa, saka, iyo inonhuwira inowedzerwa kumusanganiswa - inonhuhwirira (chinhu chine hunhu hwehuhu). LPG haina chepfu, asi haipindi mumhepo uye ine mwero muchetura mhedzisiro. Mumamiriro egasi, inorema kudarika mhepo, uye mumamiriro emvura, inoreruka kupfuura mvura. Naizvozvo, mota dzeLPG hadzifanirwe kusiiwa mumagaraji epasi, sekunge pakaitika kuvuza, LPG inogara yakagara munzvimbo dzakaderera uye ichibvisa mweya unofema.
LPG inogadzirwa panguva yekugadziriswa kwepetroleum feedstocks. Inodhakwa nekutonhora kana kumanikidza kudzikisa huwandu hwayo ka260. LPG inoshandiswa senzira inodhura pane peturu sezvo zvivakwa zvacho zvakafanana. Iyo ipeturu ine yakanaka kwazvo zvivakwa, iine octane chiyero chepakati pe101-111. Mumamiriro edu ezvinhu, iyo inonzi yechando LPG musanganiswa (60% P uye 40% B) uye zhizha LPG musanganiswa (40% P uye 60% B), i.e. shanduko mune zvakaenzana zviyero zvepropane uye butane.

Kuti uwane kutaura kwakanyatsojeka (kukosha kwecalorific, kukosha kwekoriori, nezvimwewo), iyo "Theoretical Equivalence Coefficient" inotsanangurwa sehoriyamu yemafuta ane huwandu hwesimba hwakaenzana necororific value yepeturu. Ipapo iyo "chaiyo reshiyo yakaenzana chiyero" pakati pekushandisa kweinjini yakatemwa, iyo yatinogona kuenzanisa zvakanyanya sezvinobvira.

Ngatitorei mota ine avhareji gasi mileage ingangoita 7 litita. Zvino (tichifunga nezve kuumbwa kwemusanganiswa wezhizha uye kuenzana kwekuenzana, tinowana fomula:
(peturu kushandiswa * (40 muzana propane neakaenzana ne1,27 + 60 muzana butane ine kuenzana kwe1,11 .XNUMX)) = LPG kushandiswa
7 * (0,4 * 1,27 + 0,6 * 1,11) = 7 * 1,174 = 8,218 l / 100 km v
7 * (0,6 * 1,27 + 0,4 * 1,11) = 7 * 1,206 = 8,442 l / 100 km muchando
Saka, mutsauko mune chaiwo mamiriro ekunze achave 0,224/ 100 km. Kusvika pari zvino, idzi dzese nhamba dzedzidziso, asi dzinotsanangura chokwadi chekuti kushandiswa kuchakura chete nekuda kwekutonhora. Ehe, ivo vanewo mhosva yekuwedzera kuwedzera kwekushandisa - matai echando, nguva yechando inotanga, kupenya kwakawanda, chando munzira, pamwe kunyange kushoma gumbo kunzwa, nezvimwe.
