I-Intake Air Cooler: Indima Yomqaphi Wamandla kanye Nezimpawu Zephutha
Emndenini wezinjini ezine-turbocharger, i-input air cooler ngokungangabazeki "iyisivikelo samandla". Ibonakala ithobekile kodwa idlala indima ebalulekile ekukhuliseni amandla nasekuvikeleni injini. Ngesikhathi esifanayo, ukwehluleka kwayo kungaba nemiphumela emibi eminingi ekusebenzeni kwezimoto, okudinga abashayeli ukuba bayiqaphele ngaso sonke isikhathi.
1. I-Intake Air Cooler: I-Core Assist yezinjini ze-Turbocharged
Izinjini ezine-turbocharger zandisa umthamo womoya ongenayo ngokucindezela umoya, ngaleyo ndlela zithuthukise amandla. Kodwa-ke, ngesikhathi sokucindezela, izinga lokushisa lomoya likhuphuka kakhulu, lifinyelele ku-150°C noma ngaphezulu. Ukwanda kwezinga lokushisa kunciphisa ukuminyana komoya kanye nokuqukethwe komoya-mpilo, okuthinta ukusebenza kahle kokushaja kwenjini. Kuleli qophelo, i-input air cooler iyaqala ukusebenza.
Umsebenzi oyinhloko wesithasiselo somoya opholile ukwehlisa izinga lokushisa lomoya ocindezelwe. Ngokusebenzisa izinhlelo zokupholisa umoya noma zokupholisa amanzi, singapholisa umoya oshisayo ongenayo ufike ku-50-80°C. Umoya obandayo oqinile ungandisa ivolumu yokungenisa cishe ngo-30%, okuvumela ukushiswa kukaphethiloli okuphelele kanye nokukhishwa kwamandla okunamandla. Idatha ikhombisa ukuthi ngaphansi kwezimo ezifanayo zesilinganiso somoya-kaphethiloli, njalo ukwehla ngo-10°C kokushisa komoya okune-turbocharged kungandisa amandla enjini ngo-3% kuya ku-5%.
Ngaphezu kokukhulisa amandla, i-input air cooler nayo "iyisivikelo" senjini. Umoya oshisayo ongapholisiwe ongena ekamelweni lokushisa uzobangela amazinga okushisa aphezulu kakhulu okushisa, okwandisa kakhulu ingozi yokuqhuma, futhi ezimweni ezimbi kakhulu, kulimaza ama-piston, ama-valve, nezinye izingxenye. I-input air cooler inganciphisa amathuba okuqhuma ngaphezu kuka-60%, kanti izinga lokushisa lomoya okungenisa elizinzile linganciphisa nokuqukethwe kwe-NOx ku-exhaust yenjini, kwehlise ukukhishwa okuyingozi ngo-20%-30%, kusize izimoto zihlangabezane nezindinganiso eziqinile zokukhishwa.
Ngokuphathelene nokonga uphethiloli, i-air cooler ethatha umoya nayo iyasiza. Umoya opholile ophakeme ungathuthukisa ukusebenza kahle kwe-atomization kaphethiloli ngo-15%, kuhlanganiswe nokulawulwa okunembile kwesilinganiso somoya-kaphethiloli, kufinyelele ukwanda okungu-5%-8% kokonga uphethiloli. Izinjini ezine-turbocharger ezine-air cooler ezithatha umoya zidla uphethiloli ongaphansi ngo-10%-15% kunezinjini ezizithungela zona ezinamandla afanayo. Ezindaweni eziphakeme, i-air cooler ethatha umoya ingandisa ukuminyana kokungenisa ngo-25%, kuhlanganiswe ne-turbo enesilinganiso sokucindezela okuphezulu, kunciphisa ukulahlekelwa kwamandla kusuka ku-35% kuya ku-15%, okuvumela izimoto ukuthi zigcine amandla aqinile ngisho nasemigwaqweni ephakeme.
2. Ukuphazamiseka Kwephutha: Izimpawu Ezivamile Zokwehluleka Kokupholisa Umoya Okungenisa
Uma isiqandisi somoya esingenayo singasebenzi, imoto izothumela ngokushesha "isignali yokuphepha". Abashayeli kudingeka baqaphele lezi zimo ezingavamile.
Ukwehla kwamandla kuyisibonakaliso esisobala kakhulu. Lapho i-air cooler yokungenisa ihluleka, umoya oshisayo awukwazi ukuphola ngempumelelo, okuholela ekunciphiseni kobuningi bokungenisa. Ngesikhathi sokusheshisa okusheshayo, i-turbo isabela kancane, ijubane lenjini liyakhuphuka kodwa ijubane lemoto alikhuphuki kakhulu. Lapho idlula noma ikhuphuka, kuzoba nokuntuleka kwamandla okuphawulekayo. Imisebenzi eyayilula kakhulu ngaphambili izoba nzima kakhulu, futhi ukushelela kokushayela kuzoncishiswa kakhulu.
Ukwanda okukhulu kokusetshenziswa kukaphethiloli nakho kuyisibonakaliso esivamile. Ukungasebenzi kahle komoya opholile kuzobangela ukwehla kokusebenza kahle kokungenisa, futhi uphethiloli awukwazi ukushiswa ngokuphelele. Ngaphansi kwebanga elifanayo, imvamisa yokugcwalisa uphethiloli izokwanda kakhulu, futhi izindleko zokusebenzisa imoto zizokhuphuka kakhulu. Ngesikhathi esifanayo, ukusha okungaphelele kuzobangela intuthu emnyama emgqonyeni wokukhipha uphethiloli, okungagcini nje ngokungcolisa imvelo kodwa futhi kuyisibonakaliso esisobala sokusebenza okungajwayelekile kwenjini.
Isiqandisi somoya esingena kahle singadala umonakalo ngaphakathi kwenjini. Uma isiqandisi somoya esingena sivuza kakhulu, izinhlayiya zesihlabathi zingangena kwisilinda, zikhulise ukuguguleka kwesilinda, zibangele ukusebenza kwenjini okungazinzile, ukuthuthumela okungavamile, nomsindo. Ukusha okungaphelele isikhathi eside kuzobangela inani elikhulu lekhabhoni kuma-valve nasemakhanda esilinda, okuholela ebunzimeni bokusha kwenjini, ukungahlali kahle okungazinzile, kanye nokugxuma okungazinzile kokungenzi lutho lapho ulinde izibani zomgwaqo. Ekuseni, kuzothatha isikhathi eside ukuqala imoto, futhi ukungahlali kahle kuzohlala kungazinzile lapho ulinde izibani zomgwaqo.
Ngaphezu kwalokho, ngokutholwa kwe-OBD, kungatholakala ukwanda okungavamile kokushisa komoya ongenayo. I-air cooler esebenzayo ingapholisa umoya ocindezelwe kusukela ku-200°C kuya ku-50-80°C. Uma inephutha, izinga lokushisa lomoya ongenayo lingadlula i-100°C, futhi izinga lokushisa eliphakeme eliqhubekayo lizobangela ukuqhuma. Ngokuhamba kwesikhathi, lizolimaza i-piston nesilinda. Uma i-coolant ivuza ku-intercooler epholiswe ngamanzi, noma uma kukhona amabala kawoyela ebusweni be-intercooler epholiswe umoya, kuzothinta umphumela wokushabalalisa ukushisa futhi kuholele ochungechungeni lwamaphutha.
III. Ukulungiswa Kwansuku Zonke: Gcina i-Intercooler "iku-inthanethi"
Ukuqinisekisa ukusebenza okuqhubekayo kwe-intercooler, ukulungiswa kwansuku zonke kubalulekile. Kunconywa ukuhlanza isinki yokushisa ye-intercooler njalo ngamakhilomitha angu-20,000, ikakhulukazi ngemva kokushayela ibanga elide, ukuvimbela uthuli ukuthi lungavimbeli futhi kuthinte ukusebenza kahle kokushabalalisa ukushisa. Ngesikhathi esifanayo, hlola njalo ipayipi lokungenisa. Uma kutholakala amabala kawoyela, kungase kube ngenxa yezimbozo ezigugile, futhi kudingeka zishintshwe ngesikhathi. Uma usebenzisa i-antifreeze ebusika basenyakatho, khetha incazelo enephuzu leqhwa elingu--35°C ukuvimbela i-intercooler ukuthi ingabi makhaza ngaphakathi.
Ukuze uhlole ukuthi i-intercooler iyavuza yini, ungangeza isisombululo se-sodium carbonate esingu-2% ku-70 kuya ku-80°C ku-intercooler ize igcwale. Linda imizuzu eyi-15 bese ubheka ukuthi kukhona yini ukuvuza. Uma kukhona ukuvuza, kudinga ukulungiswa ngesikhathi.
Nakuba i-intercooler ingeyona into ebonakala kakhulu emotweni, idlala indima ebalulekile ekukhipheni amandla, ekuvikelweni kwenjini, kanye nokonga uphethiloli. Ukuqonda umsebenzi wayo, ukujwayelana nezimpawu zayo zephutha, kanye nokwenza ukulungiswa njalo kungagcina injini ene-turbocharger isesimweni esihle kakhulu futhi kunikeze umshayeli ulwazi lokushayela olubushelelezi.
