Nekufambira mberi kuri kuita maindasitiri muChina, chiyero chekusvibiswa kwemhepo chatanga kukwira, uye zvakakosha kuvandudza kusvibiswa kwezvakatipoteredza. Mukupindura matambudziko aya, hurumende yeChina yakabva yatanga mitemo yakawanda yakakodzera yekuburitswa kwemhepo muinjini yedhiziri. Pakati payo, mainjini edhiziri ane simba guru repamusoro ane utsi hweNational III neEuro III mumusika wejenareta yedhiziri ari kuwedzera kufarirwa mumusika.
Injini yedhiziri ine simba guru inoreva sisitimu yekupa mafuta inoparadzanisa zvachose kugadzirwa kwesimba rekuisa jekiseni uye maitiro ekuisa jekiseni muhurongwa hwakavharwa hunoumbwa nepombi yemafuta ine simba guru, sensor yepressure uye electronic control unit (ECU). Injini dzedhiziri dzinodzorwa nemagetsi hadzichavimbi nekudzika kwethrottle yemutyairi kudzora huwandu hwepombi yemechanical injection, asi dzinovimba neECU yeinjini kuti igadzirise ruzivo rwemuchina wese. ECU ichaongorora mamiriro einjini panguva chaiyo uye ichagadzirisa injection yemafuta zvichienderana nenzvimbo yeaccelerator pedal. Nguva uye huwandu hweinjection yemafuta. Mazuva ano, mainjini edhiziri anoshandiswa zvakanyanya mu "time pressure control" fuel injection system yechizvarwa chechitatu, kureva, high-pressure common injection system.
Zvakanakira mainjini edhiziri emhando yepamusoro anoshandisa simba rakawanda remagetsi ndekuti anoshandisa mafuta mashoma, akavimbika zvakanyanya, anogara kwenguva refu, uye ane simba rakawanda. Mainjini edhiziri ane common rail anoburitsa magasi asina njodzi zvakanyanya pane mainjini asina common rail (kunyanya CO shoma), saka haakuvadzi nharaunda kana tichienzanisa neinjini dzepeturu.
Zvakaipa zvemainjini edhiziri ane simba guru zvinosanganisira mitengo yakawanda yekugadzira nekugadzirisa (mitengo), ruzha rwakanyanya, uye kuoma kwekutanga. Kana injini ichishanda kwenguva yakareba, tembiricha yeinjini nekumanikidzwa kwayo kwakakwira, uye soot necoke zvakawanda zvinogadzirwa mumasilinda, uye oiri yeinjini inogonawo kuoxidation kuti igadzire gums. Saka, oiri yeinjini yedhiziri inoda detergent yakanaka yekupisa kwakanyanya.
