Kodi chowongolera utsi chimagwira ntchito bwanji?
Mfundo yogwirira ntchito ya chowongolera mpweya wotuluka ndi makamaka kudzera mu kukhazikitsa kasupe wobwerera, njira ya torque imasiyana ndi njira ya torque yopita patsogolo ya camshaft, kuti zitsimikizire kuti chowongolera mpweya wotuluka chibwerere bwino. Pakugwira ntchito kwa injini, ndi kusintha kosalekeza kwa momwe zinthu zikuyendera, gawo la camshaft liyenera kusinthidwa mosalekeza, ndipo kasupe wobwerera adzazungulira mosinthana ndi kusintha kwa gawo. Kusunthaku kungayambitse kutopa kwa kasupe wobwerera, kotero ndikofunikira kuyesa mphamvu yayikulu yomwe imachokera ku kasupe wobwerera mukamagwira ntchito kuti mudziwe chitetezo cha kutopa cha kasupe.
Mfundo yogwirira ntchito ya exhaust phase regulator imakhudzanso lingaliro la exhaust phase ya injini, kutanthauza nthawi yotsegulira ndi kutseka ndi nthawi yotsegulira ya exhaust valves yolowera ndi yotuluka yomwe imayimiridwa ndi crankshaft Angle. crankshaft angle nthawi zambiri imayimiridwa ndi chithunzi chozungulira cha crank Angle poyerekeza ndi malo a crank apakati omwe ali pamwamba ndi pansi, omwe angawoneke ngati njira yopumira ndi kutulutsa mpweya m'thupi la munthu. Ntchito yayikulu ya valavu ndikutsegula ndi kutseka exhaust valves yolowera ndi yotuluka ya silinda iliyonse malinga ndi nthawi inayake, kuti akwaniritse njira yonse yosinthira mpweya wa silinda ya injini.
Mu ntchito zinazake zaukadaulo, monga ukadaulo wa VTEC, kudzera mu kusintha kwanzeru kwa makina owongolera zamagetsi, imatha kusintha magulu awiri a ma valavu osiyanasiyana pa liwiro lotsika komanso liwiro lalikulu, kuti igwirizane ndi zosowa za mikhalidwe yosiyanasiyana yoyendetsera injini. Mfundo yogwirira ntchito ya VTEC ndi yakuti injini ikasinthidwa kuchoka pa liwiro lotsika kupita pa liwiro lalikulu, kompyuta yamagetsi imatsogolera molondola kuthamanga kwa mafuta kupita ku camshaft yolowera, ndikuyendetsa camshaft kuti izungulire m'madigiri 60 kudzera mu kuzungulira kwa turbine yaying'ono, motero kusintha nthawi yotsegulira valavu yolowera kuti ikwaniritse cholinga chosinthira nthawi ya valavu. Ukadaulo uwu umathandizira bwino kuyaka, kumawonjezera mphamvu zotulutsa, komanso kuchepetsa kugwiritsa ntchito mafuta ndi mpweya woipa.
Kodi ntchito ya wowongolera gawo la utsi ndi yotani?
Ntchito yaikulu ya chowongolera gawo la utsi ndikusintha gawo la camshaft malinga ndi kusintha kwa momwe injini imagwirira ntchito, kuti isinthe kuchuluka kwa utsi ndi mphamvu ya injini, kuwongolera nthawi yotsegulira ndi kutseka ndi ngodya ya valavu, kenako kukonza mphamvu ya injini, kukonza mphamvu ya kuyaka, ndikuwonjezera mphamvu ya injini.
Chowongolera gawo la utsi chimazindikira kukhathamiritsa kwa magwiridwe antchito a injini kudzera mu mfundo yake yogwirira ntchito. Pogwira ntchito, injini ikazima, chowongolera gawo la intake chimakhala pamalo ochedwerapo kwambiri, ndipo chowongolera gawo la utsi chimakhala pamalo apamwamba kwambiri. Camshaft ya injini imazungulira molunjika ku kuchedwerapo pansi pa mphamvu ya torque yotsutsana ndi wotchi. Kwa chowongolera gawo la utsi, malo ake oyamba amakhala pamalo apamwamba kwambiri, kotero torque ya camshaft iyenera kugonjetsedwa kuti ibwerere pamalo oyamba injini ikayimitsidwa. Kuti chowongolera gawo la utsi chibwerere bwino, kasupe wobwerera nthawi zambiri amayikidwa pamenepo, ndipo torque yake imakhala yosiyana ndi torque yotsogola ya camshaft. Injini ikakhala ikugwira ntchito, ndi kusintha kosalekeza kwa momwe ntchito ikuyendera, gawo la camshaft liyenera kusinthidwa mosalekeza, ndipo kasupe wobwerera adzazungulira mosinthana ndi kusintha kwa gawo. Kuchita izi kumathandiza kukonza magwiridwe antchito a injini, kuphatikiza mphamvu yowonjezera, torque ndi kuchepetsa mpweya woipa.
Kuphatikiza apo, kapangidwe ndi kagwiritsidwe ntchito ka zowongolera magawo otulutsa utsi kumaphatikizaponso kutsatira malamulo otulutsa utsi wa injini. Chowongolera gawo la camshaft chakhala chikugwiritsidwa ntchito kwambiri mu injini ya petulo ndi malamulo okhwima a kutulutsa utsi wa magalimoto. Mwa kusintha nthawi zonse Angle ya valve overlap, chowongolera gawo la camshaft chimatha kuwongolera mosavuta komanso moyenera kukwera kwa injini ndi kuchuluka kwa mpweya wotsalira wa utsi mu silinda, motero kukonza magwiridwe antchito a injini ndikuchepetsa mpweya woipa .
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
