Izinjini zedizili, njengedivaysi yamandla asebenza kahle, zisetshenziswa kabanzi kwezokuhamba, embonini, ezolimo nakwezinye izinkambu. Okulandelayo ukufingqwa kolwazi oluyisisekelo kuwe kusuka ezicini ezinjengemigomo eyisisekelo, izici ezihlelekile, izinzuzo nokubi, izimo zohlelo lokusebenza kanye nentuthuko yezobuchwepheshe:
Isimiso Esiyisisekelo: I-Charm yokucindezela ukucindezela
Umehluko omkhulu phakathi kwezinjini zedizili kanye nezinjini zikaphethiloli indlela yokulahla:
Izinjini ze-Diesel zifinyelela ekuphumeni ngo- "Ukushisa umoya ocindezelwe" - umoya ongenanhlonipho ucindezelwe yi-piston (isilinganiso sokushintshana kwesinye isikhathi kungu-15-22: 1, okuphezulu kakhulu kune-8-12 Ngalesi sikhathi, i-ufake ugesi ifaka udizili oluphakeme lwe-disel kwisilinda, futhi udizili ovele ulibhale ngokuhlangana nomoya wokushisa aphezulu, ecindezela ipiston ukwenza umsebenzi. Injini kaphethiloli "iyakhishwa": ingxube yamafutha negesi kubhalwe yi-plug ye-spark.
Izakhi eziyinhloko zenjini yedizili zifaka:
Isilinda kanye ne-Piston: Qedela umjikelezo wesifo sohlangothi ezine (ukudla → ukucekelwa phansi → amandla → ukhetho).
I-High-Full Pull Pump + I-Indercr: I-Diesel (izinhlelo zesitimela zesimanje (zesitimela sanamuhla zingafinyelela ngaphezulu kwe-2000bar), elawula kahle isikhathi nenani lomjovo we-petrol.
I-turbocharger: Isebenzisa amandla okuqeda amandla ukushayela i-turbine, icindezele umoya omningi kumasilinda kanye namandla okuthuthukisa.
I-EGR (uhlelo lokuphinda usebenzise igesi)
