Ua kom lub cav torque rau nws tus kheej

Txhua engine muaj ib co yam ntxwv. Nyob rau hauv ib co lawv muaj ntau tshaj li lwm tus. Tag nrho peb paub tias rau qhov zoo tshaj plaws kev kawm ntawm cov tsheb yuav tsum tau ntau lub hwj chim, tab sis ob peb paub dab tsi torque lub cev muaj zog. Cias muab - nws yog ib lub caij ntawm kev quab yuam, uas yog txuas mus rau lub crankshaft tig nws nyob rau hauv ib tug tag nrho cov voj voog. Nws yog ib zajlus kom muaj kev pov plob hais tias yog ib tug quab yuam, nws yog ntsuas nyob rau hauv nm. Yog li, lub siab dua qhov qhab nia, qhov ntau dynamic tsheb.

Tab sis, yog hais tias lub hwj chim tsub kom mus txog 5500-6000 rpm, lub siab tshaj plaws torque ntawm lub engine yog tsim ntawm ib tug loj tsawv ceev. Raws li rau diesel xyaw, lawv muaj xws li ib tug yam ntxwv tiag superior roj av, txij li thaum cov neeg kawm ntawv ntawm compression nyob rau hauv lawv yuav luag ob zaug kom ntau li ntau, yog li ntawd, lub piston txuas zoo zog, uas yog ces kis tau mus rau lub crankshaft.

Zoo li nws los yog tsis, feem ntau engine yog lub "Quartet". Lawv ntim txawv, tab sis manufacturers raws precisely qhov no, vim nws yog yooj yim mus rau qhov chaw tus ntoo khaub lig, Ntxiv, nws tsis yog raws li kim rau tsim li, hais tias, "rau". Tab sis ib tug indisputable qhov tseeb yog qhov point uas qhov kev nce rau hauv lub xov tooj ntawm thooj voos kheej kheej, tsis muaj kev hloov lwm yam ntxwv, ua rau yus mus rau ib tug proportional nce nyob rau hauv torque. Piv txwv li, yog hais tias tus cav torque, uas muaj ib tug kheej kheej 4 thiab 2 liv ntawm volume, yog 150 nm, lub nce nyob rau hauv lub xov tooj ntawm thooj voos kheej kheej 6 tsa nws mus txog 225 nm. Lawm, nws yog tsim nyog los noj mus rau hauv tus account losses vim kev sib txhuam thiab lwm yam sab nraum rog, li ntawd, lub net nce yog hais txog ib feem peb, uas yog thaum kawg - 200 nm.

Torque thiab lub hwj chim tas li ua kom. Qhov yooj yim txoj kev uas yuav ua li no - kom txo tau qhov ntim ntawm lub combustion chamber los yog lwm yam txhais tau tias yuav ua tau kom lub compression ratio. Nyob rau hauv cov ntaub ntawv no, nws yog ib nqi nco ntsoov cav Tshuag, vim hais tias lub tog raj kheej taub hau yuav tsuas nyuaj siab nrog studs los yog bolts.

Qhov thib ob hom - qhov chaw kawm lub crankshaft nrog ib tug loj lub hauv caug. Nyob rau hauv cov ntaub ntawv no, lub cav revving lub caij nplooj zeeg yuav tsum tau hloov thiab thooj voos kheej kheej, vim hais tias cov piston stroke hloov. Nyob rau hauv qhov tseeb - qhov no yog ib tug yooj yim nce nyob rau hauv cov ua hauj lwm ntim.

Tam sim no - ib tug me ntsis kev tshawb xav. Rov qab mus rau peb nce tus naj npawb ntawm thooj voos kheej kheej. Yuav ua li cas yog nws thiaj li zoo? Qhov tseeb hais tias nyob rau hauv thawj cov ntaub ntawv (4) nyob rau hauv lub combustion chamber tawg tshwm sim txhua txhua 180 degrees. Qhov no txhais tau hais tias tag nrho ntev ntawm lub piston stroke yog siv lub zog ntawm ib tug kheej kheej. Nyob rau hauv lub rau-lub tog raj kheej engine tawg tshwm sim txhua txhua 90 degrees ntawm crankshaft kev sib hloov. Nyob rau hauv cov ntaub ntawv no, kom txog thaum lub piston kom dhau ib nrab ntawm cov ua hauj lwm mob stroke, muaj lwm tawg nyob rau hauv lwm lub tog raj kheej, lub crankshaft yog tam sim no tig rau ob piston. Thaum tus thawj nce mus txog rau hauv qab tuag center, thiab lub thib ob yuav tsum tau muaj partway, tawg nyob rau hauv lub thib peb, thiab hais txog. Obviously, xws li ib tug tsim yog zoo.

Cav torque - nws yog heev ib qho tseem ceeb feature, uas muaj peev xwm txheeb xyuas lub tsev ntawm tag nrho cov. Nyob rau hauv xaus, nws yog tsim nyog ntxiv hais tias lub bulkier xyaw muaj siab torque thiab ntau lub hwj chim.
