Qhov no ua rau qhov tseeb tias hom cav no yuav tsum muaj qhov sib txawv ntawm lub sijhawm sib txawv dua li lub tshuab siv lub taub hau. 

Qhov tsis zoo tshaj qhov zoo

Hmoov tsis zoo, lub cav qis qis muaj qhov tsis zoo tshaj qhov zoo. Qhov no yog ib tug archaic tsim tam sim no tsuas yog siv rau mower cav. Nyob rau hauv xws li ib chav tsev, qhov sib piv compression feem ntau yog tsawg dua 8, uas txhais tau hais tias hom kev siv sij hawm no tsuas yog siv tau rau hauv lub tshuab hluav taws xob. 

Qhov loj tshaj qhov tsis zoo ntawm lub tshuab qis qis yog, qhov tseem ceeb tshaj plaws, kev siv lub tshuab qis. Qhov no txhais tau hais tias, piv txwv li, ib liter ntawm kev hloov chaw ua rau lub zog tsawg dua li ntawm cov khoom siv hluav taws xob valve. Hmoov tsis zoo, lub tshuab hluav taws xob qis tsis mus koom tes nrog kev siv roj tsawg, thiab tib lub sij hawm lub cav tsis muaj zog, kev ncua sij hawm rau qhov sib ntxiv ntawm cov roj tau pom meej meej.

Lub cav qis-valve muaj ntau lub tog raj kheej tsis ua haujlwm, uas deformed vim kev sib cuag tsis tu ncua nrog cov pa cua kub. Tus tsim ntawm lub cev muaj zog tsis tau tso cai rau kev siv lub tog raj kheej ntub dej nrov. Ib qho kev tsis zoo tseem yog qhov ua tiav ntawm qhov qis compression piv. Qhov no yog vim qhov tshwj xeeb tsim ntawm lub taub hau.

Cov txiaj ntsig ntawm lub tshuab hluav taws xob overhead valve

Lub cav hauv qab valve yog qhov yooj yim tshaj plaws tsim ntawm tag nrho plaub-stroke maus taus thiab qhov no yog lub ntsiab kom zoo dua ntawm cov powertrains. Vim nws tsim, nws tau yooj yim ntsia rau ntawm maus taus, tab sis nws feem ntau tsis meej pem nrog lub me me capacitive unit. Txhua tus ua tsaug rau lub taub hau me me uas muab cov ntaub ntawv saib rau tag nrho qhov project. 

Thib peb faib - hybrid sij hawm

Tej zaum koj yuav raug siv los faib cov tshuab hluav taws xob sab hauv rau hauv qis-valve thiab sab sauv-valve. Muaj cov qauv tsim me me uas muab cov kev daws teeb meem ntawm ob lub cav. Lawv raug hu ua cov cav tov sib xyaw thiab raug txheeb xyuas los ntawm lub cim IOE. Nyob rau hauv cov ntaub ntawv ntawm cov units, lub intake li qub nyob rau hauv lub taub hau, thiab cov pa li qub nyob rau hauv lub cav thaiv. Qhov kev daws teeb meem no yog ib daim ntawv qhia rau kev tshem tawm cov teeb meem thermal cuam tshuam nrog deformation ntawm lub tog raj kheej liner. 

Lub cav qis valve - nws tsim nyog xaiv

Yog tias koj tau ntsib teeb meem ntawm kev yuav lub tsheb uas siv lub valve, nws yuav ua pov thawj koj txoj kev mob siab rau lub tsev cia puav pheej tsheb. Koj yuav tsum paub tus nqi kho tsheb uas muaj hnub nyoog tshaj 50 xyoo.
