Imoto yeChery EASTAR B11 ene-mileage emalunga ne-80000 km, exhotyiswe nge-automatic transmission kunye nemodeli ye-injini ye-Mitsubishi 4g63. Umsebenzisi uxele ukuba injini yemoto ishukuma emva kokuqala, kwaye imoto ebandayo inzulu. Umnini waxela kwakhona ukuba kuyabonakala xa kulindelwe isibane (oko kukuthi, xa imoto ishushu, injini ishukuma ngokunzulu xa ingasebenzi).
Uhlalutyo lwemposiso: kwi-injini yemoto elawulwa nge-elektroniki, oonobangela besantya sokungenzi nto esingazinzanga bantsonkothile kakhulu, kodwa iimpazamo eziqhelekileyo zesantya sokungenzi nto zinokucazululwa kwaye kufunyaniswe kule miba ilandelayo:
1. Ukusilela koomatshini
(1) Uloliwe wevalvu.
Oonobangela abaxhaphakileyo beziphene zezi: ① ixesha elingalunganga levalvu, njengokungalungelelaniswa kakuhle kwamanqaku exesha xa kuhlonyelwa ibhanti lexesha levalvu, okukhokelela ekutshisweni okungaqhelekanga kwesilinda ngasinye. ② Amalungu othumelo lwevalvu anxitywe kakhulu. Ukuba enye (okanye ngaphezulu) iikhamera zinxitywe ngokungaqhelekanga, ukungena kunye nokukhupha okulawulwa ziivalve ezihambelanayo azilingani, okukhokelela ekuqhumeni okungafaniyo kwamandla okuqhuma kwe-cylinder nganye. ③ Idibaniso yevalvu ayisebenzi ngokwesiqhelo. Ukuba i-valve itywina ayiqinile, uxinzelelo loxinzelelo lwe-cylinder nganye aluhambelani, kwaye kunye ne-cylinder compression ratio iyatshintshwa ngenxa ye-carbon deposition enzulu kwintloko yevalve.
(2) Ibhloko ye-cylinder kunye ne-crank yokudibanisa intonga.
① Ucoceko oluhambelanayo phakathi kwe-cylinder liner kunye nepiston inkulu kakhulu, "ukukhutshwa okuthathu" kweringi yepiston ayiqhelekanga okanye ayinakunwebeka, kwaye "nokuhambelana" kweringi yepiston kwenzeka. Ngenxa yoko, uxinzelelo loxinzelelo lwe-cylinder nganye aluqhelekanga. ② Ukubekwa kwekhabhoni enzulu kwigumbi lokutsha. ③ Ibhalansi eguquguqukayo ye-injini ye-crankshaft, i-flywheel kunye ne-crankshaft pulley ayifanelekanga.
(3) Ezinye izizathu. Umzekelo, iphedi yeenyawo ze-injini yophukile okanye yonakele.
2. Ukungaphumeleli kwenkqubo yokungenisa umoya
Iimeko eziqhelekileyo ezibangela iziphene ziquka:
(1) Ukuvuza kweendawo ezininzi zokungena okanye izivalo zevalvu eyahlukeneyo, njengokuvuza komoya kwegasket yokungena ngeendlela ezininzi, ukukhulula okanye ukugqabhuka kweplagi yombhobho wokufunxa, njl.njl., ukuze umoya ongafanelekanga ungene kwi-cylinder, utshintshe umxube womxube, kunye kukhokelela ekutshisweni kwenjini okungaqhelekanga; Xa indawo yokuvuza komoya ichaphazela kuphela iisilinda zomntu ngamnye, injini iya kungcangcazela ngamandla, nto leyo enempembelelo ecacileyo kwisantya esibandayo esingasebenziyo.
(2) Ukungcola okugqithisileyo kwi-throttle kunye ne-intake port. I-valve yangaphambili yenza i-valve ye-throttle ibambelele kwaye ivalwe ngokukhululekileyo, ngelixa lo mva uya kutshintsha icandelo lokuthatha, eliya kuchaphazela ulawulo kunye nokulinganisa umoya wokungenisa kwaye kubangele isantya esingazinzanga sokungenzi lutho.
3. Iimpazamo eziqhelekileyo ezibangelwa yimpazamo yenkqubo yokubonelela ngamafutha ziquka:
(1) Uxinzelelo lweoyile yenkqubo ayiqhelekanga. Ukuba uxinzelelo luphantsi, inani leoli elifakwe kwi-injector lincinci, kwaye umgangatho we-atomization uba mbi ngakumbi, okwenza umxube kwi-cylinder ibe yincinci; Ukuba uxinzelelo luphezulu kakhulu, umxube uya kuba nobutyebi kakhulu, oya kwenza ukutshiswa kwi-cylinder kungazinzi.
(2) Isitofu sesibaso ngokwaso sinempazamo, njengokuba umngxuma womlomo uvalekile, ivalve yenaliti ixingile okanye i-solenoid coil itshisiwe.
(3) Umqondiso wokulawula isitofu sesibaso awuqhelekanga. Ukuba i-fuel injector ye-cylinder ingaba nokusilela kwesekethe, ubuninzi be-injector ye-fuel ye-fuel injector yale cylinder iyakungahambelani neyezinye iisilinda.
4. Ukungaphumeleli kwenkqubo yokutshisa
Iimeko eziqhelekileyo ezibangela iziphene ziquka:
(1) Ukusilela kweplagi yentlantsi kunye nocingo olunombane ophezulu lukhokelela ekuncipheni okanye ekulahlekeni kwamandla entlantsi. Ukuba i-gap ye-spark plug ayifanelekanga, i-high-voltage wire ivuza umbane, okanye ixabiso le-calorific ye-spark plug ayifanelekanga, ukutshiswa kwe-cylinder kuya kuba yinto engaqhelekanga.
2
(3) Impazamo ye-engile yokulayita kwangaphambili.
5. Iimpazamo eziqhelekileyo ezibangelwa yi-injini ye-electronic control system iimpazamo ziquka:
(1) Ukuba imodyuli yokulawula i-injini yombane (ECU) kunye nemiqondiso eyahlukeneyo yokufaka igalelo iyasilela, umzekelo, isantya se-injini ye-crankshaft kunye ne-cylinder top of dead center signal ilahlekile, i-ECU iya kuyeka ukukhupha umqondiso wokutshisa kwimodyuli yokutshisa, kwaye i-cylinder iya kuvutha kakubi.
(2) Ukungaphumeleli kwenkqubo yokulawula isantya sokungenzi nto, njengemoto yokunyathela engasebenziyo (okanye ivalve ye-solenoid engasebenziyo) ibambekile okanye ingasebenzi, kunye nomsebenzi ongaqhelekanga wokuzifundela.
Phuhlisa amanyathelo:
1. Ukuqinisekiswa kwangaphambili kokusilela kwesithuthi
Emva kokuqhagamshelana nesithuthi esinempazamo, umnini waziswa ngokubuza ukuba isithuthi sangcangcazela ngesantya esingasebenziyo emva kokuqalisa; Ndajonga i-spark plug ndafumanisa ukuba kukho i-carbon deposit kwi-spark plug. Emva kokutshintsha i-spark plug, ndaziva ngathi i-jitter yancitshiswa, kodwa impazamo isekhona.
Emva kokuqalisa injini kwisiza, kufunyaniswe ukuba isithuthi sijija ngokucacileyo, kwaye impazamo ikhona: emva kokuqalisa okubandayo, akukho ngxaki kwinqanaba eliphezulu lokungenzi nto. Emva kokuba i-idle ephezulu iphelile, isithuthi siyajija ngokucacileyo ngokuphindaphindiweyo kwi-cab; Xa ubushushu bamanzi buqhelekile, i-frequency yokugubha iyancitshiswa. Kuvakala ngesandla kumbhobho wokukhupha ukuba umbhobho awulingani ngamaxesha athile, kunye "nokutsha kweposi" kufana nokuqhushumba okuncinci kunye nokukhupha okungalinganiyo.
Ukongeza, sifunde kule ncoko ukuba isithuthi somnini sisetyenziselwa ukuhamba nokuphuma emsebenzini, kunye nomgama oziikhilomitha ezili-15 ~ 20km ngexesha ngalinye, kwaye akufane kwenzeke ukubaleka ngesantya esiphezulu. Xa ulinde isibane se-traffic ukuba sime, kuyisiko ukunyathela kwi-pedal ye-brake, kwaye i-shift handle ayinakubuyela kwi-"n" gear.
2. Chonga impazamo ukusuka kokulula ukuya kwangaphandle, kwaye emva koko uchonge impazamo ukusuka kokulula ukuya kwangaphandle.
(1) Qwalasela izinto ezine zokuxhoma (uzipho) zokudityaniswa kwe-injini, kwaye ufumanise ukuba kukho umkhondo omncinci wokudibana phakathi kwephedi yerabha yesixhobo sokuxhoma sasekunene kunye nomzimba. Ukwandisa ukucoceka ngokufaka i-shims kwi-screws yokukhwela, qalisa isithuthi sokuvavanya, kwaye uzive ukuba i-jitter ngaphakathi kwe-cab iyancitshiswa. Emva kovavanyo lokuqalisa kwakhona, i-jitter isabonakala emva kokuphela kokungenzi lutho. Idityaniswe nesenzeko sokuphuma ngokungalinganiyo, kunokubonwa ukuba esona sizathu siphambili asikho ukumiswa, kodwa umsebenzi ongalinganiyo we-injini.
(2) Khangela inkqubo yokulawula i-elektroniki kunye nesixhobo sokuxilonga. Akukho khowudi yempazamo kwisantya esingasebenziyo; Ukuhlolwa kokuhamba kwedatha ngolu hlobo lulandelayo: ukungena komoya malunga ne-11 ~ 13kg / h, i-injection ye-fuel pulse ububanzi yi-2.6 ~ 3.1ms, 3.1 ~ 3.6ms emva kokuba i-air conditioner ivuliwe, kwaye ubushushu bamanzi yi-82 ℃. Ibonisa ukuba i-injini ye-ECU kunye ne-injini yokulawula inkqubo ye-elektroniki iyinto eqhelekileyo.
(3) Khangela inkqubo yokutshisa. Kufunyenwe ukuba umgca we-high-voltage we-cylinder 4 wonakaliswe kunye nokuvuza kombane. Faka endaweni yomgca we-high-voltage wale cylinder. Qala injini kwaye impazamo ayiphuculwanga kakhulu phantsi kwesantya esingasebenziyo. Ekubeni umniniyo engazange atshintshe i-spark plug ixesha elide, impazamo ebangelwa yi-spark plug inokuhoywa.
(4) Jonga inkqubo yokubonelela ngamafutha. Qhagamshela igeyiji yokujonga uxinzelelo lolondolozo kwisekethe yeoli yenkqubo yokubonelela ngamafutha kunye nesinxibelelanisi se tee. Emva kokuqalisa i-injini, isantya kwaye ubuninzi boxinzelelo lwe-oyile bunokufikelela kwi-3.5bar. Emva kwe-1h, uxinzelelo lwe-gauge luhlala luhlala lu-2.5bar, lubonisa ukuba inkqubo yokubonelela ngamafutha iyinto eqhelekileyo. Ngethuba lokuchithwa kunye nokuhlolwa kwe-injector ye-fuel injector, kufunyenwe ukuba i-injector ye-fuel ye-cylinder 2 inendawo efanayo yokuchithwa kweoli, njengoko kuboniswe kuMzobo 1. Faka indawo ye-injector ye-fuel ephosakeleyo ye-cylinder 2. Qala injini kunye nephutha ayinakupheliswa.
