Yiluphi uhlelo lokupholisa lwemoto eyizingxenye ezimbili?

Uhlelo olupholisa kabili lwemoto

Isistimu yokupholisa kabili. Amanye amamodeli ezinjini zikaphethiloli ezine-turbocharged asebenzisa isistimu yokupholisa yesekethe ekabili. Isifunda esisodwa sihlinzeka ngokupholisa injini. Omunye umoya opholile wokushaja. Amasekhethi okupholisa azimele komunye nomunye. Kodwa banokuxhumana futhi basebenzisa ithangi elivamile lokunweba. Ukuzimela kwamasekethe kukuvumela ukuthi ugcine izinga lokushisa elihlukile le-coolant ngayinye yazo. Umehluko wokushisa ungafinyelela ku-100 ° C. Hlanganisa ukugeleza kokupholisa, ungavumeli ama-valve amabili okuhlola nama-throttles. Isekhethi yokuqala iyisistimu yokupholisa injini. Isistimu yokupholisa evamile igcina injini ifudumele. Ebangeni lika-105 ° C Ngokungafani nezinga elijwayelekile. Esimisweni sokupholisa se-dual-circuit, izinga lokushisa ekhanda le-cylinder libekwe ebangeni lika-87 ° C. Futhi ku-cylinder block - 105 ° C. Lokhu kutholakala ngokusebenzisa ama-thermostats amabili.

Uhlelo lokupholisa olunezigaba ezimbili

Ngokuyisimiso uhlelo lokupholisa olunezigaba ezimbili. Njengoba umjikelezo wekhanda lesilinda udinga ukugcinwa emazingeni okushisa aphansi, okupholile kuhamba kahle kuwo. Cishe i-2/3 yenani eliphelele. I-coolant esele iyazungeza kumjikelezo wesilinda. Ukuqinisekisa ukupholisa okufana kokufana kwekhanda lesilinda, kupholile kusakazwa kuyo. Eqondisweni oluvela ekuphindaphindweni okuphelele kuya kokuphindaphindayo kokudla. Lokhu kubizwa ngokuthi ukupholisa okudlulile. Uhlelo olupholisa kabili lwenjini. Izinga eliphakeme lokupholisa lekhanda lesilinda lihambisana nomuntu opholile kakhulu ophansi. Le ngcindezi iphoqelelwa ukunqoba i-thermostat lapho ivula. Ukwenza lula ukwakheka kohlelo lokupholisa. Enye yama-thermostats yakhelwe ngomthethonqubo osezigabeni ezimbili.

Ukusebenza kwesistimu epholile kabili

Isitofu se-thermostat enjalo siqukethe izingxenye ezimbili ezixhumene. Ipuleti elincane nelikhulu. Ipuleti elincane liyavula kuqala, elikhuphula ipuleti elikhulu. Uhlelo lokupholisa lulawulwa uhlelo lokuphathwa kwezinjini. Lapho injini iqala, womabili ama-thermostat ayavala. Inikeza ukushesha kwenjini okufudumele. Isiqandisini sijikeleza isiyingi esincane esizungeze ikhanda lesilinda. Ukusuka kwimpompo ngekhanda lesilinda, i-heater heat exchanger, i-oyela ebandayo bese kungena ithangi lokunwebeka. Lo mjikelezo wenziwa kuze kufike lapho izinga lokushisa elipholile lifinyelela ku-87 ° C. Ku-87 ° C, i-thermostat iyavula ngokujikeleza kwekhanda lesilinda. Ipholile iqala ukujikeleza isiyingi esikhulu. Ukusuka kwimpompo ngekhanda lesilinda. I-Wmv, i-burn exchanger, i-cooler epholile, i-thermostat evulekile, i-radiator bese ithatha ithangi lokunwebeka.

I-thermostat ivula kuliphi izinga lokushisa?

Lo mjikelezo wenziwa kuze kube yilapho i-coolant ku-cylinder block ifinyelela ku-105 ° C. Ku-105 ° C, i-thermostat ivula i-cylinder block circuit. Uketshezi luqala ukujikeleza kulo. Kulesi simo, izinga lokushisa kumjikelezo wekhanda le-cylinder lihlala ligcinwa ku-87 ° C. Isifunda sesibili yisistimu yokupholisa umoya yokushaja. Uhlelo lwesistimu yokupholisa umoya yokushaja. Uhlelo lokupholisa komoya olushaja luqukethe into epholile, irediyetha kanye nephampu. axhunywe ngamapayipi. Uhlelo lokupholisa luqukethe nezindlu zamabheringi e-turbocharger. I-refrigerant in the circuit isakazwa ngepompo ehlukile. Okwenziwa kusebenze, uma kunesidingo, ngesignali evela kuyunithi yokulawula injini. Uketshezi oludlula endaweni epholile lususa ukushisa emoyeni oshajiwe. Bese ipholiswa kurediyetha.

Imibuzo nezimpendulo:

Yini efakiwe ohlelweni lokupholisa injini? Lolu hlelo luqukethe ijakhethi yokupholisa imoto, ipompo ye-hydraulic, i-thermostat, amapayipi axhumayo, irediyetha kanye nesiphephetha-moya. Ezinye izimoto zisebenzisa amadivaysi engeziwe ahlukene.

Isebenza kanjani isistimu yokupholisa yesekethe ekabili? Uma injini ikwimodi yokushisisa, okokupholisa kuzungeza kuyindilinga encane. Lapho injini evuthayo yangaphakathi ifinyelela izinga lokushisa lokusebenza, i-thermostat iyavuleka bese into epholile izungeza kurediyetha kuyindilinga enkulu.

Kungani udinga isistimu yokupholisa eyiziyingi ezimbili? Ngemuva kokuphelelwa yisikhathi, injini kufanele ifinyelele ngokushesha izinga lokushisa lokusebenza, ikakhulukazi emakhazeni. Umbuthano omkhulu wokujikeleza uhlinzeka ngokupholisa injini.
