1) Taw qhia rau diesel cav qhov chaw tsim khoom lag luam
Diesel xyaw yog cov qauv uas muaj kev ua haujlwm siab tshaj plaws, kev siv lub zog zoo tshaj plaws, thiab kev txuag hluav taws xob tshaj plaws ntawm txhua yam ntawm cov tshuab fais fab tam sim no siv hauv kev lag luam. Lawv tau dhau los ua neeg nyiam hauv kev lag luam tsheb, tshuab ua liaj ua teb, engineering machinery, nkoj, diesel locomotives, geological thiab roj drilling rigs, tub rog, Nws yog lub ntsiab txhawb zog rau cov khoom siv dav dav, mobile thiab backup fais fab chaw nres tsheb thiab lwm yam khoom siv. Muaj ntau hom diesel xyaw. Tam sim no, feem ntau siv kev faib tawm yog raws li tus naj npawb ntawm lub tog raj kheej thiab lawv siv: lawv feem ntau muab faib ua plaub pawg raws li tus naj npawb ntawm lub tog raj kheej, uas yog ib lub tog raj kheej diesel xyaw, me me-bore multi-lub tog raj kheej diesel xyaw, nruab nrab. - bore multi-lub tog raj kheej diesel xyaw thiab nruab nrab-tsawg ceev diesel xyaw. Ob pawg tom kawg Feem ntau hu ua nruab nrab thiab hnyav-lub luag haujlwm diesel cav, lawv yog cov kev taw qhia tseem ceeb ntawm kev txhim kho lub cav diesel tam sim no; Raws li lawv siv, lawv tuaj yeem muab faib ua ob pawg: marine diesel xyaw thiab tsheb diesel xyaw.
Kev lag luam diesel cav yog ib ceg tseem ceeb ntawm kev lag luam tshuab. Txoj kev loj hlob ntawm kev lag luam diesel cav muaj kev cuam tshuam loj heev rau kev lag luam, kev ua liaj ua teb, kev thauj mus los, kev tsim kho hauv tebchaws, thiab tib neeg lub neej. Diesel cav qhov chaw tsim kev lag luam yog kev lag luam nce toj ntawm lub tshuab hluav taws xob kev lag luam thiab feem ntau koom nrog kev tsim cov khoom tseem ceeb xws li diesel cav cylinder blocks, lub tog raj kheej taub hau, pistons, crankshafts, txuas rods, thiab camshafts.
2) Cov yam ntxwv ntawm diesel cav qhov chaw tsim khoom lag luam
Diesel xyaw yog dav siv thiab nyob rau hauv ib tug tseem ceeb txoj hauj lwm nyob rau hauv lub lag luam saw uas lawv koom. Nyob rau hauv kaum xyoo dhau los ntawm txoj kev loj hlob, kev lag luam diesel cav tsim tau tsim cov tuam txhab txhawb nqa. Ntau lub tuam txhab diesel cav ua si ntau lub luag haujlwm ua cov khoom sib dhos. Qee qhov tseem ceeb ntawm lub cav diesel: crank txuas pas nrig, Pistons, lub tog raj kheej liner, camshafts, thiab lwm yam tau tsim los ntawm cov tuam txhab kev tshaj lij. Kev faib ua haujlwm tshwj xeeb tso cai rau cov tuam txhab tsim hluav taws xob diesel tsom mus rau lawv tus kheej qhov zoo thiab tsom mus rau kev tsim thiab tsim cov cav diesel.
Tom qab xyoo ntawm txoj kev loj hlob, kuv lub teb chaws lub diesel cav tshuab tau ua tau zoo, thiab qhov sib txawv ntawm tag nrho cov kev kawm theem ntawm kev lag luam thiab lub ntiaj teb no cov kev txawj ntse theem tau maj mam nqaim. Tshwj xeeb tshaj yog nyob rau hauv xyoo tas los no, nyob rau hauv cov kev taw qhia ntawm lub teb chaws lub tswv yim ntawm kev taw qhia, digestion, absorption thiab re-innovation, cov tuam txhab uas muag nyob rau hauv kev lag luam tau them nyiaj ntau thiab ntau rau cov kev siv technology tshiab thiab cov reserves ntawm technology, raws li zoo raws li daim ntawv thov ntawm tshiab technologies thiab txheej txheem. Cov lag luam hauv tsev tau nce lawv cov cuab yeej thev naus laus zis los ntawm kev qhia, kev zom thiab nqus ntawm txawv teb chaws diesel cav technologies, tshwj xeeb tshaj yog diesel cav lub zog-txuag thiab emission txo technologies, thiab cov txheej txheem ntawm cov khoom siv diesel cav kuj tseem tau txhim kho tas li los ntawm kev nqus thiab rov tsim dua tshiab. .
3) Kev lag luam nqes qis ntawm cov cav diesel cav yog qhov loj
Txij li thaum lub tshuab hluav taws xob yog siv rau hauv cov khoom txhawb nqa zaum kawg, cov khoom siv cav diesel tau siv dav hauv kev lag luam xws li tsheb thauj khoom, tsheb npav, kev tsim kho tshuab, tshuab ua liaj ua teb, nkoj, railway diesel locomotives, chaw nres tsheb thiab cov khoom siv hluav taws xob. Txoj kev loj hlob ntawm lub cav diesel thiab qhov chaw lag luam yog sib txuas nrog cov kev lag luam hauv qab. Txoj kev loj hlob ntawm lub diesel cav qhov chaw tsim kev lag luam nyob rau hauv ib tug loj npaum li cas ntawm kev ua lag luam tej yam kev mob ntawm cov khoom kawg.
Raws li kev txheeb cais los ntawm Tuam Tshoj Internal Combustion Engine Industry Association, kuv lub teb chaws tag nrho cov cav diesel muag hauv 2021 yog 6.1084 lab units (xws li 238,300 units rau cov neeg caij tsheb, 2.9675 lab units rau kev lag luam tsheb, 1.0481 lab units rau engineering machinery, 1.4648 lab units rau ua liaj ua teb machinery, thiab 1.4648 lab units rau marine machinery. 40,200 units, 317,500 units rau kev tsim hluav taws xob, thiab 31,900 units rau kev siv dav). Xyoo 2022, kuv lub teb chaws tag nrho cov cav diesel muag yog 4,286,600 units (suav nrog 188,700 units rau cov neeg caij tsheb, 1,670,100 units rau kev lag luam tsheb, thiab 837,200 units rau engineering machinery. 311.700 Nws tau siv rau kev tsim hluav taws xob, thiab 16,900 units tau siv rau lub hom phiaj dav dav). Qhov laj thawj tseem ceeb yog vim li cas kev muag khoom ntawm diesel xyaw rau kev lag luam tsheb poob sai heev.
