Nekuramba kuchikwira kwemitengo yemafuta uye nemirau yakawedzera kuomesera ekubvisa mafuta, vagadziri vemotokari nevagadziri veinjini vanoshingairira matekinoroji akasiyana epamusoro kuderedza kushandiswa kwemafuta einjini uye kuburitsa.
Simba rinogara riripo rinotora tekinoroji yekupfapfaidza yemukati megomba replasma kupfapfaidza tekinoroji yakasarudzika pamadziro emukati megomba rehumburumbira, uye inoshandisa zvinhu zvakasiyana-siyana zvekuputira kuti isangane nezvinodiwa zveinjini, senge husina kunaka hwemafuta uye kupfeka kwakanyanyisa. , kukwenya kana kukora kunokonzerwa ne exhaust gas recirculation rate (EGR).
Iyi tekinoroji yakashandiswa mumotokari, marori, mudhudhudhu uye mainjini emugungwa, pamwe nemasilinda liners egasi ejini, injini dzemagetsi uye gasi compressors.
Munguva pfupi yapfuura,Zhengheng simbazvakabudirira kuunza batch yechipiri yehupenyu hurefu hwedhizirihumburumbira injiniliner kuenda kune inozivikanwa fekitori injini yedhiziri muChina.
Kune iyi cylinder liner yehupenyu hurefu, iyo yekupfeka yakasarudzwa ndeye cermet composite, iyo ine mukana wekudzikisa zvakanyanya kukweshera uye kupfeka kwecylinder bore wall.
Panguva imwecheteyo, nekuti iyo yekupfekedza ine zvidimbu zveceramic uye zvakakosha zvinhu, kushomeka kwayo kunogona kuvandudzwa, uye hupenyu hwayo hwesevhisi huchave hwakareba kupfuura iyo yechinyakare cast iron cylinder liner.
Scania, anonyanya kuzivikanwa anogadzira marori ekunze, akatotora nzira imwechete yekupfapfaidza uye zvinhu sesimba rinogara riripo painjini yayo, ichiziva ngano yekuti rori rayo harina kugadziridzwa kwemamiriyoni matatu emakiromita.
