Muinjini inomhanya, ine stethoscope inopesana negomba repombi, uchichinja injini kumhanya, pombi inotakura kupfeka muganho kana kushomeka kwemafuta, unogona kunzwa jecha, jecha, ruzha rwejecha; iruzha rushoma.

Pombi isina kujairika inzwi rinowanzoita pombi shaft inotakura kupfeka, kusununguka kana kushaikwa kwemafuta, pombi shaft inochengeta mhete haina kuisirwa kana kusaiswa, inotakura chiteshi, impeller kumashure uye pombi yemvura inovhara chivharo uye inokonzeresa pulley uye fan impeller ichizunza ruzha. blade neruoko uye ongorora pombi shaft.Kana iwe uchigona kunzwa yakawandisa axial uye radial clearance, zvinoratidzwa kuti faniro yakasakara kana yakasununguka uye inofanirwa kubviswa kuti igadziriswe.

Mumotokari injini cylinder block, kune akawanda ekutonhodza mvura yekutenderera chiteshi, uye anoiswa pamberi pemota radiator (inowanzozivikanwa setangi remvura) kuburikidza nemapombi emvura akabatana kuti aumbe hombe yemvura inotenderera system, yekubuda painjini, ine ine pombi yemvura, inosundwa nebhandi re fan, mukati meinjini cylinder block water heat pombi, pombi ichienda kunotonhora.

Padivi pepombi yemvura uye thermostat, kutonhora (mota), kana mota ichangotanga kusavhurika, ita mvura inotonhorera isina tangi remvura, mukati meinjini kutenderera (inowanzozivikanwa sediki cycle), kukurumidza kukurudzira pamusoro pekushisa kwe. 95 madhigirii, anovhurwa, mvura inopisa inoputirwa mutangi injini mukati, kana mota iri pamhepo inotonhora ichivhuvhuta tangi remvura, kupisa kunogona kubviswa.
