Yintoni umgaqo wokukhupha ivalvu yemoto
Umsebenzi osisiseko wevalvu yokukhupha umoya yemoto kukulawula igesi yokukhupha umoya ephuma kwisilinda ukuqinisekisa ukuba igesi yokukhupha umoya emva kokutsha inokukhutshwa ngokufanelekileyo, ukwenza indawo yomoya omtsha kunye nomxube wamafutha, ukuze kugcinwe umjikelo wokutsha oqhubekayo wenjini.
Umgaqo wokusebenza kwevalvu yokukhupha umoya yemoto usekelwe kwiindlela ezine ezisisiseko zenjini: ukungena, ukucinezelwa, ukusebenza kunye nokuphuma komoya. Ngexesha lokuphuma komoya, i-piston iya phezulu kwaye ivalvu yokukhupha umoya ivuleke, ivumela igesi yokukhupha umoya ukuba iphume kwisilinda. Ukuvulwa nokuvalwa kwevalvu yokukhupha umoya kulawulwa yi-camshaft, kwaye imilo ye-CAM kwi-camshaft imisela ixesha lokuvula kunye nobude bevalvu yokukhupha umoya. Ngokukodwa, ivalvu yokukhupha umoya idla ngokuba nevalvu, isihlalo, intwasahlobo, kunye nesiqu. Ivalvu ihlala ivaliwe ngesenzo sentwasahlobo ide i-CAM kwi-camshaft ityhale isiqu kwaye yoyise amandla entwasahlobo ukuvula ivalvu. Nje ukuba i-CAM ye-camshaft idlule, intwasahlobo iyayivala ngokukhawuleza ivalvu, iqinisekisa ukuba igesi yokukhupha umoya ayibuyi .
Ukulungiswa nokugcinwa kweevalvu zokukhupha umoya Ngokusebenzisa itekhnoloji yexesha levalvu eguquguqukayo, iinjineli zeemoto zanamhlanje zilungisa ixesha lokuvula kunye nobude bevalvu yokukhupha umoya ngokwesisindo kunye nomthwalo wenjini ukuphucula ukusebenza kakuhle kokutsha kunye nokunciphisa ukukhutshwa komoya. Ukongeza, ezinye iinjini ezisebenza kakuhle zinoyilo lweevalvu ezininzi ezineevalvu ezininzi zokungenisa kunye nezokukhupha umoya ngesilinda nganye ukwandisa isantya sokuhamba komoya kunye nokuphucula ukusebenza kakuhle kokutsha. Ukugcinwa rhoqo kunye nokuhlolwa kwevalvu yokukhupha umoya kunokuqinisekisa ukuba isebenza kakuhle, kubandakanya ukujonga ukuguguleka kwevalvu kunye nesihlalo, ukutshintsha iindawo ezigugileyo, kunye nokulungisa indawo apho ivalvu ivaliwe khona.
Indima ephambili yokukhupha ivalvu yemoto ibandakanya ezi zinto zilandelayo:
Ukunciphisa ukuxhomekeka kwibhreki yenkonzo: ivalvu yebhreki yokukhupha umoya inokunciphisa kakhulu ukuxhomekeka kwibhreki yenkonzo kwinkqubo yokuqhuba, ngaloo ndlela inciphisa izinga lokuguguleka kwezihlangu zebhreki okanye iidiski, kwaye iphephe ngempumelelo iingozi zokhuseleko ezibangelwa kukugqithisa rhoqo kwebhreki.
Inkqubo ye-turbocharging ezinzileyo: Ivalvu yokukhupha umoya idlala indima ebalulekileyo kwinkqubo ye-turbocharging, enokuzinzisa uxinzelelo lokuqhubeleka kwaye iqinisekise ukusebenza okuzinzileyo kwenjini kunye ne-turbocharger. Ngokulawula uxinzelelo olungasemva lokukhupha umoya, ivalvu yokukhupha umoya yenza ngcono ukusebenza kwenjini, ngakumbi kwi-RPM ephakathi ukuya phezulu.
isandi sokulawula i-exhaust: Isixhobo se-valve exhaust singalawula ubungakanani besandi se-exhaust kwaye silungise isandi sombhobho we-exhaust ngokuvula nokuvala i-valve. Xa i-valve ivaliwe, isandi se-exhaust sincinci, sifanele ukusetyenziswa kwindawo ezolileyo; Xa i-valve ivuliwe, isandi se-exhaust siyanda, njengesandi semoto yezemidlalo.
Iingenelo zokusingqongileyo: igesi yokukhupha umoya ngevalvu ngokurisayikilisha inani elincinci legesi elahliweyo kwi-cylinder combustion, ukunciphisa ubushushu bokutsha, ngaloo ndlela kuthintela ukuveliswa kwe-NOx, ukunciphisa umxholo we-NOx kwi-exhaust gas, kunceda ekukhuseleni okusingqongileyo.
Iindlela ezahlukeneyo zokulawula : iindlela zokulawula ukukhupha ivalvu zahlukile, ezinokufezekiswa ngolawulo olukude, i-APP yefowuni ephathwayo okanye ulawulo lwesantya oluzenzekelayo. Xa usebenzisa ulawulo olukude, cofa nje iqhosha lokuvula, isignali engenazingcingo iya kudluliselwa kumlawuli wevalvu, kwaye umlawuli uya kulawula ivalvu ukuba ivuleke emva kokufumana umyalelo.
