Injini ikhipha i-exhaust gas e-grey-white, okubonisa ukuthi uphethiloli othile uyaphuma epayipini le-exhaust ngenxa yamazinga okushisa aphansi enjini, ukungangeni kahle kwe-athomu kawoyela negesi, kanye nophethiloli osephuze kakhulu ukuthi ungasha.

Izizathu eziyinhloko zalesi simo yilezi:

1) Uma isikhathi sokujova uphethiloli sekwephuze kakhulu, umjovo unamadriphu lapho ujova uphethiloli, umfutho womjovo uphansi kakhulu, futhi i-atomization impofu. Uma izinga lokushisa lomshini liphansi kakhulu, sekwephuzile kakhulu ukuthi lingasha futhi likhishwa ngendlela yentuthu emhlophe. Isixazululo ukulungisa isikhathi somjovo nokuhlola isimo sokusebenza komjovo.

2) Ukucindezela okunganele ku-cylinder. Ngenxa yokuguga kwe-cylinder liner kanye ne-piston ring ring, kanye nokuvalwa kahle kwe-valve, injini ikhipha intuthu empunga nemhlophe uma isanda kuqalwa, bese iphenduka intuthu emnyama encane noma intuthu emnyama njengoba izinga lokushisa lenjini likhuphuka. Isixazululo ukufaka esikhundleni se-cylinder liner egugile, iringi ye-piston noma ukunquma iringi ye-valve nesihlalo se-valve.

3) Kukhona amanzi ku-diesel fuel. Uma injini ikhipha intuthu emhlophe ngokumpunga ngemva kokuba iqalile, futhi intuthu emhlophe empunga isekhona njengoba izinga lokushisa lenjini likhuphuka, kungenzeka ukuthi kunamanzi amaningi axutshwe kudizili. Isixazululo ukuvula i-valve yokudonsa ithangi ngaphambi kokuqala umshini nsuku zonke ukukhipha intlenga namanzi phansi ethangini.

Ukufingqa, ukuphuma kwentuthu okungavamile kuwukubonakaliswa okuphelele kokuhluleka kwangaphakathi kwenjini. Ngakho-ke, ukuthi i-exhaust ijwayelekile noma cha ingenye yezimpawu ezibalulekile zokwahlulela isimo sokusebenza senjini. Uma ingaphathwa ngesikhathi, ingaqinisekisa ukusetshenziswa kahle kwenjini kadizili futhi igweme ukulahlekelwa kwezomnotho okungadingekile..
