I-valve yokulawula uwoyela.
Ikuphi i-valve yokukhulula uwoyela ye-MAXUS G10?
Ivalvu yokukhulula uwoyela ye-MAXUS G10 ngokuvamile itholakala kubhulokhi yenjini. Ukuze uthole ivalvu eqondile yokukhulula uwoyela, landela iphasishi likawoyela eduze nesihlungi sikawoyela nepompo likawoyela. Lolu lwazi lwendawo lubalulekile ekuqondeni ukusebenza nokugcinwa kwesistimu kawoyela, ikakhulukazi lapho kwenziwa ukunakekelwa okuhlobene nokucindezela kukawoyela kanye nomsebenzi wokulungisa, lapho ukubeka ngendlela efanele kuqinisekisa ukusebenza kahle nokuphepha 1.
I-valve yokulawula uwoyela ibizwa nangokuthi i-OCV valve, ikakhulukazi ngomzimba we-valve (okuhlanganisa ikhoyili kagesi, isixhumi semojula yokulawula), i-slide valve, i-spring yokusetha kabusha nokunye.
Isimiso sokusebenza se-valve yokulawula uwoyela: Ukunikezwa kwamandla okusebenza kwekhoyili ye-solenoid yevalvu yokulawula uwoyela kunikezwa i-relay eyinhloko elawulwa yiyunithi yokulawula injini. Iyunithi yokulawula injini isebenzisa isignali yokushintshashintsha kwe-pulse ukulawula ikhoyili kagesi yevalve yokulawula uwoyela ngemva kokumiswa kanye nokunika amandla ukukhiqiza indawo kazibuthe ukuze ilawule ukusebenza kwe-spool, ukuze iguqule ngokuqhubekayo ubudlelwano besikhathi phakathi kwe-crankshaft ne-camshaft, ukuze injini ikwazi ukuthola isigaba se-valve esingcono kakhulu ngaphansi kwezimo ezihlukene zokusebenza. Qaphela ukulawulwa kwesigaba se-valve.
Umsebenzi we-valve yokulawula uwoyela: Isigaba se-valve esifanele ngokulawulwa kwe-valve yokulawula uwoyela sisiza ukukhulisa ukusebenza kahle kwenjini, ukuthuthukisa ukuzinza okungenzi lutho futhi kunikeze i-torque namandla amakhulu, kuyilapho kusiza ukuthuthukisa ukonga kukaphethiloli nokunciphisa ukukhishwa kwe-hydrocarbon ne-nitrogen oxide.
Izimpawu eziyinhloko zokuhluleka kwe-valve yokulawula umfutho kawoyela
Imoto ingase icime kungazelelwe ngesikhathi ishayela : lokhu kungenxa yokuthi i-valve yokulawula uwoyela ayikwazi ukulungisa umfutho kawoyela ngendlela evamile, okuholela ekugcobeni kwenjini okwanele.
umfutho kawoyela ongajwayelekile : uma umfutho kawoyela uphezulu kakhulu, lokho kuzoholela ekuhlanganiseni okukhulu kakhulu, intuthu emnyama evela epayipini lokukhipha umoya, futhi amandla emoto awanele.
ukwanda kokusetshenziswa kukaphethiloli : Ngenxa yokuthi i-valve elawula umfutho kawoyela ayikwazi ukulawula umfutho kawoyela ngokujwayelekile, okuholela ekutheni umjovo ngesikhathi esifanayo ujove uwoyela owengeziwe, ngaleyo ndlela andise ukusetshenziswa kukaphethiloli.
Ezinye izimpawu ezihlobene
umfutho kawoyela ongajwayelekile : umfutho kawoyela ungaba phezulu kakhulu noma ube phansi kakhulu, kuphazamise ukusebenza okujwayelekile kwenjini.
isivinini sokungenzi lutho esingazinzile : Ukulimala kwevalvu elawula umfutho kawoyela kungase kubangele isivinini esingazinzile sokungenzi lutho.
Intuthu emnyama evela ku-exhaust : Uma i-valve elawula umfutho kawoyela yonakele, ingxube izoba nkulu kakhulu bese kukhishwa intuthu emnyama epayipini le-exhaust.
Amandla enjini anganele : ukulimala ku-valve elawula umfutho kawoyela kuzophazamisa ukusebenza kwamandla enjini, kubangele amandla anganele.
Ukusetshenziswa kukaphethiloli okuphezulu : ukulimala kwevalvu elawula umfutho kawoyela kuzoholela ekusetshenzisweni kukaphethiloli okuphezulu.
Ingabe i-valve yokulawula umfutho kawoyela idinga ukuhlanzwa?
Idinga
Ivalvu yokulawula uwoyela kawoyela idinga ukuhlanzwa. Lapho intwasahlobo yevalvu yokunciphisa ingcindezi isithambile kakhulu noma iphukile, kuba khona ukungcola okubhajwe kuvalvu, futhi umfutho kawoyela uyoba phansi kakhulu uma isiphethu noma ivalvu (ibhola lensimbi) ingafakwanga ngesikhathi sokulungiswa; Uma ukucindezela kwentwasahlobo kukhulu kakhulu noma i-valve ayikwazi ukuvulwa ngenxa yokuxhuma okungcolile, ukucindezela kwamafutha kuzoba phezulu kakhulu. Ngakho-ke, ukuhlolwa kwesevisi kudinga ukuhlanza umhlangano we-valve futhi kuhlole ukuguquguquka kokushelela kwe-plunger noma ibhola kanye nokunwebeka kwentwasahlobo. .
Ukuvama kanye nesidingo sokuhlanza: Ukuhlanza isekethe kawoyela kuwumsebenzi obalulekile wokulungisa, kodwa akudingekile ukwenza konke ukulungisa. Ukuhlanzwa njalo kwesekethe kawoyela kuzodala umonakalo omkhulu kusiguquli se-catalytic yezindlela ezintathu. Imvamisa yokuhlanza ejwayelekile kufanele ibe ngu-30,000-40,000 km/isikhathi, futhi ikhule noma yehle ngokuya ngezimo zomgwaqo nezimo zemoto. Ukuhlanza isifunda samafutha akudingekile, kodwa uma umfutho wamafutha uphansi, buyisela isihlungi samafutha.
