Nekuenderera mberi kwekuvandudzwa kwemaitiro ekugadzira maindasitiri eChina, indekisi yekusvibiswa kwemhepo yatanga kukwira, uye zvinofanirwa kuvandudza kusvibiswa kwezvakatipoteredza. Kupindura kune akatevedzana matambudziko aya, hurumende yeChina yakakurumidza kuunza mitemo yakawanda yakakodzera yekuburitsa injini yedhiziri. Pakati pavo, high-pressure yakajairika njanji dizeli injini ine National III uye Euro III emissions mudhiziri jenareta set musika ari kuwedzera uye mukurumbira mumusika.
Iyo yakakwirira-yakajairika njanji yedhiziri injini inoreva nzira yekugovera mafuta inoparadzanisa zvachose chizvarwa chekumanikidza jekiseni uye chirongwa chejekiseni mune yakavharwa-loop system inoumbwa ne-high-pressure fuel pombi, pressure sensor uye electronic control unit (ECU) . Iyo ECU ichaongorora iyo chaiyo-nguva mamiriro einjini munguva chaiyo uye kugadzirisa jekiseni remafuta zvichienderana nenzvimbo yeanomhanyisa pedal. Nguva uye vhoriyamu jekiseni remafuta. Mazuva ano, injini dzedhiziri dzinoshandiswa zvakanyanya muchizvarwa chechitatu "nguva yekumanikidza kutonga" mafuta ejekiseni system, kureva, high-pressure common rail.
Zvakanakira zveyakanyanya-kudzvanywa yakajairika njanji dizeli ishoma kushandiswa kwemafuta, kuvimbika kwakanyanya, hupenyu hurefu, uye yakakwirira torque. Diesel injini dzine njanji dzakajairika dzinoburitsa magasi asingakuvadzi zvakanyanya pane injini dzisina njanji (kunyanya shoma CO), saka dzine hushamwari hwezvakatipoteredza zvichienzaniswa neinjini dzepeturu.
Kuipa kweinjini yedhiziri yepamusoro-inomanikidza njanji inosanganisira mitengo yakakwira yekugadzira nekugadzirisa (mitengo), ruzha rwakanyanya, uye kunetsa kutanga. Kana injini ichishanda kwenguva yakareba, tembiricha yeinjini uye kudzvanywa kwakakwira, uye soot yakawanda uye coke ichagadzirwa mumasirinda, uye injini yemafuta inotarirwawo neoxidation kugadzira chingamu. Naizvozvo, dizeli injini mafuta inoda yakanaka yepamusoro-tembiricha detergency.
