Kumvetsetsa Gear Valve ndi Impact Yake pa Kutulutsa Kwa Injini

Zida za valve ndi chimodzi mwazinthu zofunika kwambiri za injini, makamaka pozindikira zomwe zimatuluka.Ili ndi udindo woyang'anira kayendedwe ka mafuta ndi mpweya zomwe zimalowa ndi kutuluka m'zipinda zoyaka moto za injiniyo.Zida za valve zimakhala ndi zigawo zingapo zolumikizana, kuphatikizapo camshaft, tappets, pushrods, rockers, ndi valves, zomwe zimagwirira ntchito limodzi kuwongolera momwe injini ikuyendera.

Chimodzi mwazofunikira pankhani ya zida za valve ndi kuchuluka kwa kukweza ndi kutalika kwa kutseguka kwa valve.Kukweza kumatanthawuza mtunda umene valve imatsegula pamene nthawi ndi nthawi yomwe valve imakhala yotseguka.Kuchuluka kwa kukwezedwa ndi kutalika kwake kumatanthawuza kuchuluka kwa mpweya ndi mafuta omwe injini ingatengere, zomwe zimakhudza zotsatira zake.

Pali mitundu yosiyanasiyana ya ma valavu omwe amagwiritsidwa ntchito mu injini, kuphatikizapo single-overhead cam (SOHC), dual-overhead cam (DOHC), ndi pushrod.Iliyonse mwa ma giya a valvewa ili ndi maubwino ndi zovuta zake, ndipo kumvetsetsa kusiyana kwawo kungakuthandizeni kusankha yoyenera kuti mugwiritse ntchito injini yanu.

Mwachitsanzo, zida za valavu za SOHC, ndizosavuta koma zimatha kupereka mphamvu, torque, komanso mafuta.Komano, zida za valavu za DOHC zimakhala zovuta kwambiri koma zimatha kupititsa patsogolo magwiridwe antchito a injini pogwiritsa ntchito mpweya wabwino komanso kutulutsa mpweya, makamaka pa RPM yapamwamba.Zida za Pushrod valve, zomwe nthawi zambiri zimagwirizanitsidwa ndi injini zakale, nthawi zambiri zimakhala zotsika komanso zimapangidwira ma torque ambiri kuposa mphamvu za akavalo.

Zikafika pakukhathamiritsa kutulutsa kwa injini pogwiritsa ntchito zida za valve, cholinga chachikulu ndikukwaniritsa mpweya wabwino kwambiri.Izi ndichifukwa choti kuyenda kwa mpweya ndikofunikira popanga njira yoyaka yomwe imapanga mphamvu.Njira imodzi yowonjezerera kutuluka kwa mpweya ndiyo kugwiritsa ntchito zida zokwezera kwambiri kapena valavu yanthawi yayitali, zomwe zimalola injini kuti itenge mafuta ndi mpweya wambiri.Komabe, njirayi ili ndi malire ake, kutulutsa komaliza kutengera zinthu monga kusamuka kwa injini, kapangidwe ka mutu wa silinda, komanso kuyaka bwino.

Njira ina yowonjezerera kutulutsa kwa injini pogwiritsa ntchito zida za valve ndikuwongolera nthawi ya valve kuti muthe kugwiritsa ntchito mphamvu ya injiniyo komanso mphamvu zamahatchi.Mutha kukwaniritsa izi poyesa ma profailo osiyanasiyana a cam, omwe amawonetsa kuti ma valve amatseguka ndi kutseka liti komanso kuchuluka kwake.Cholinga apa ndikuwonetsetsa kuti ma valve amatsegulidwa mokwanira panthawi ya kuyaka, zomwe zimalola kuti mafuta ndi mpweya azisakanikirana kuti apange mphamvu zambiri.

Pomaliza, zida za valve ndizofunikira kwambiri mu injini iliyonse, ndipo kumvetsetsa momwe zimakhudzira kutulutsa kwa injini kungakuthandizeni kukhathamiritsa ntchito ya injini yanu.Onetsetsani kuti mwasankha giya yoyenera ya valavu kuti mugwiritse ntchito injini yanu ndikuyesani nthawi ya valavu kuti mukwaniritse mpweya wokwanira komanso kutulutsa mphamvu.Pomaliza, nthawi zonse ganizirani zachitetezo ndi kudalirika mukakonza momwe injini yanu imagwirira ntchito ndipo funsani katswiri ngati simukutsimikiza zakusintha pamagetsi a injini yanu.
