Ndi chitukuko chosalekeza cha chitukuko cha mafakitale ku China, chiwerengero cha kuwonongeka kwa mpweya chayamba kukwera, ndipo ndikufunika kupititsa patsogolo kuwonongeka kwa chilengedwe. Pothana ndi mavutowa, boma la China lakhazikitsa nthawi yomweyo mfundo zambiri zofunikira pakutulutsa mpweya wa injini ya dizilo. Pakati pawo, ma injini a dizilo othamanga kwambiri omwe ali ndi National III ndi Euro III pamsika wamagetsi amagetsi akukhala otchuka kwambiri pamsika.
The mkulu-anzanu wamba njanji dizilo amatanthauza dongosolo mafuta kotunga kuti kwathunthu kulekanitsa m'badwo wa kuthamanga jekeseni ndi ndondomeko jekeseni mu dongosolo chatsekedwa-lupu wopangidwa ndi mkulu-anzanu mafuta mpope, kuthamanga sensa ndi magetsi unit control (ECU) . zamagetsi ankalamulira dizilo injini salinso kudalira dalaivala throttle kuya kulamulira jekeseni mafuta voliyumu ya makina makina a ECU ndondomeko ya makina a pampu. ECU idzayang'anira nthawi yeniyeni ya injini mu nthawi yeniyeni ndikusintha jakisoni wamafuta molingana ndi malo a accelerator pedal. Nthawi ndi kuchuluka kwa jekeseni wamafuta. Masiku ano, injini za dizilo zimagwiritsidwa ntchito kwambiri m'badwo wachitatu wa "time pressure control" jekeseni wamafuta, ndiye kuti, njanji yothamanga kwambiri.
Ubwino wa injini za dizilo za njanji zothamanga kwambiri ndizotsika mafuta, kudalirika kwambiri, moyo wautali, komanso torque yayikulu. Ma injini a dizilo okhala ndi njanji wamba amatulutsa mpweya wocheperako kuposa ma injini opanda njanji wamba (makamaka CO yocheperako), motero ndi ochezeka ndi chilengedwe poyerekeza ndi injini zamafuta.
Kuipa kwa injini za dizilo za njanji yothamanga kwambiri kumaphatikizapo mtengo wapamwamba wopanga ndi kukonza (mitengo), phokoso lambiri, ndizovuta poyambira. Ngati injini ikugwira ntchito kwa nthawi yayitali, kutentha kwa injini ndi kupanikizika kumakhala kwakukulu, ndipo mwaye wochuluka ndi coke zidzapangidwa m'masilinda, ndipo mafuta a injini amatha kukhala ndi okosijeni kuti apange chingamu. Chifukwa chake, mafuta a injini ya dizilo amafunikira kutentha kwapamwamba kwambiri.
