Iyo 396 yakatevedzana injini yedhiziri yakashandiswa zvakanyanya mungarava dzepamba, mota uye maindasitiri emagetsi emagetsi, nezvimwewo, nekuti injini ine mashandiro akavimbika, hupenyu hurefu hwesevhisi, simba repamusoro uye hupfumi uye inogona kushandurwa kuita mamwe mafuta akadai segasi rechisikigo. .1-3. Nekuwedzera kuderedzwa kwemafuta epetroleum, kushandiswa kwebiodiesel uye doro mafuta (senge methanol uye ethanol) mujini yedhiziri inowedzera.

Sezvo mafuta edoro asingakanganisi nedhiziri, chikamu chemafuta edoro mumafuta akavhenganiswa ehuni yedoro uye dhiziri kazhinji isingasviki 10%. Mafuta akavhenganiswa ane kugadzikana kwakaderera, akaiswa nyore nyore uye haagoni kuchengetwa kwenguva yakareba kunyange nekuwedzera kwe cosoluent.4-6 Inokurudzirwa kushandisa doro remafuta mujini yedizeli ne-dual-injection. Imwe nzira ndeyekupfapfaidza mafuta edoro mune yakawanda uye kupfapfaidza dhiziri sehuni yekubatidza muhumburumbira, uye imwe nzira ndeyekupfapfaidza mafuta edoro nedhiziri muhumburumbira nemajekiseni akasiyana, nedhiziri rinobatidza mafuta edoro.

Iyo jekiseni yemafuta eiyo yekutanga 396 yakatevedzana dizeli injini yakagadziridzwa, uye maviri akafanana 4-gomba majekiseni akaiswa muhumburumbira yega yega. Naizvozvo, dhiziri rinogona kupfapfaidzwa nemajekiseni maviri, kana jekiseni rimwe chete rinogona kushandiswa kupfapfaidza dhiziri uye rimwe jekiseni roshandiswa kupfapfaidza biodiesel kana mafuta edoro.

Iyo 3D combustion modhi ye396 yakatevedzana injini yedhiziri inotangwa nekushandisa computational fluid dynamics software MOTO, uye maitiro ekupisa apo yunifomu 5-gomba uye 8-gomba majekiseni uye 4-gomba mbiri-injector yakagamuchirwa uye yakaongororwa nekuenzanisa. nzira yekuvandudza nzira yekupisa ye396 yakatevedzana dizeli injini ine mbiri-injector pamwe chete kupa hwaro hwekushandisa biodiesel uye doro mafuta mune ramangwana.7, 8.
