Yooj yim hauv kev tsim thiab pheej yig ob-stroke engine - lub hauv paus ntsiab lus ntawm kev ua haujlwm yog ob-stroke. Nws txawv li cas ntawm plaub-stroke engine ntawm maus taus? Koj puas muaj XNUMX stroke diesel?
Kev ua haujlwm ntawm tshuab

Yooj yim hauv kev tsim thiab pheej yig ob-stroke engine - lub hauv paus ntsiab lus ntawm kev ua haujlwm yog ob-stroke. Nws txawv li cas ntawm plaub-stroke engine ntawm maus taus? Koj puas muaj XNUMX stroke diesel?

Raws li lub npe qhia, lub cav ob-stroke muaj ob lub voj voog ib lub voj voog. Nws yog hais txog compression thiab ua haujlwm. Cov qauv plaub-stroke kuj muaj qhov nkag thiab tso pa tawm. Txoj kev no ntawm kev ua haujlwm ntawm lub zog ua haujlwm tau pab txhawb rau lawv txoj kev yooj yim hauv kev sib piv nrog rau kev tsim ntawm plaub-stroke xyaw. Txawm li cas los, nws muaj nws drawbacks. Nws puas muaj txiaj ntsig thiab? Puas tseem tsim nyog muab cov cav no? Peb yuav muab cov lus teb meej rau cov lus nug no!

Ob-stroke engine - tsav tsim

Nyob rau hauv txhua lub cav piston, lub combustion chamber plays lub luag haujlwm tseem ceeb, thiab qhov no tsis muaj kev zam. Nyob rau hauv lub chamber, ib tug piston nyob rau ntawm ib tug txuas pas nrig reciprocates. Lub cav ob-stroke kuj feem ntau yog nruab nrog lub carburetor, txawm hais tias muaj cov chav nyob nrog cov hluav taws xob txhaj tshuaj. Ib qho tseem ceeb tshaj plaws yog lub crankcase, uas yog lub luag haujlwm rau kev tsim lub tshuab nqus tsev thiab lub zog ntawm tus neeg sawv cev combustible. Nyob rau hauv ib tug 2-stroke combustion engine, ntawm chav kawm, muaj ib tug lub tog raj kheej taub hau. Kuj tseem muaj inlet, siab thiab qhov hluav taws xob channel. tswm ciab kuj muab tso rau hauv lub taub hau.

Dab tsi yog qhov ploj lawm hauv lub cav ob-stroke? Puas yog nws muaj lub sijhawm zoo ib yam li lub tshuab plaub stroke?

Yooj yim hauv kev tsim thiab pheej yig ob-stroke engine - lub hauv paus ntsiab lus ntawm kev ua haujlwm yog ob-stroke. Nws txawv li cas ntawm plaub-stroke engine ntawm maus taus? Koj puas muaj XNUMX stroke diesel?

Piv nrog rau lub cav plaub-stroke, lub cav ob-stroke tsis muaj ob peb yam tseem ceeb. Nws yog hais txog:

  • lub tog raj kheej li qub;
  • roj sau;
  • lub sijhawm system.

Vim li cas cov ntsiab lus no tsis nyob hauv cov lus piav qhia? Valves tsis xav tau vim tias qhov txav ntawm lub piston yog lub luag haujlwm rau kaw thiab qhib qhov nkag thiab qhov chaw nres nkoj. Feem ntau lawv lub xub ntiag tsis tas yuav tsum muaj. Tsis xav tau lub twj tso kua mis roj, vim cov khoom ua haujlwm yog lubricated los ntawm cov roj uas muaj nyob rau hauv cov roj-cua sib tov. Lub sijhawm tseem tsis tau paub los ntawm 4-stroke units, vim tias nws yooj yim li sai tau.

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm ob-stroke engine - piav qhia

Yuav kom lub cav ob-stroke ua nws txoj haujlwm, nws yuav tsum tau txais lub zog. Lub voj voog ua haujlwm pib ntawm BDC ntawm lub piston. Thaum nws txav mus, lub tshuab nqus tsev yog tsim nyob rau hauv lub crankcase uas muaj cov sib tov. Thaum lub piston txav mus, cov pa tawm thiab qhov chaw nres nkoj tau raug kaw. Nyob rau theem no, qhov sib tov yog compressed thiab ignited. Yuav ua li cas thaum lub piston mus dhau TDC? Nws yog qhia downwards thiab lub tso pa channel qhib, los ntawm qhov uas cov pa pa tawm mus rau sab nraud. Cov pa roj ntau hauv lub crankcase tshuab tawm ntau dhau los ntawm lub combustion chamber, ntxuav cov pa tawm channel.

Dab tsi yog qhov zoo ntawm lub cav ob-stroke?

Yooj yim hauv kev tsim thiab pheej yig ob-stroke engine - lub hauv paus ntsiab lus ntawm kev ua haujlwm yog ob-stroke. Nws txawv li cas ntawm plaub-stroke engine ntawm maus taus? Koj puas muaj XNUMX stroke diesel?

Hauv qee lub tsheb, ob-stroke engine yog nrov vim qhov yooj yim ntawm kev tsim. Yog li ntawd, ntau qhov chaw tsis tas yuav tsum tau tsim, ua rau cov nqi qis dua. Tsis tas li ntawd, units ua haujlwm nyob rau hauv ob-stroke hom, raws li txoj cai, muaj ntau lub zog thiab torque. Qhov tsis muaj lub lauj kaub roj txhais tau tias lawv tuaj yeem ua haujlwm hauv txhua txoj haujlwm, tsis tas yuav ntsug. Pib lub cav zoo li no kuj yooj yim heev. Chav tsev sai sai ncav cuag qhov kub thiab txias, uas yog lwm qhov zoo dua.

Ob peb qhov tsis zoo ntawm Ob-Stroke Cav

Yog li, yog tias 2T units (raws li ob-strokes hu ua) muaj ntau qhov zoo, vim li cas lawv thiaj li tsis zoo? Qhov laj thawj tseem ceeb yog vim li cas ib puag ncig. Lub cav 4-stroke hlawv roj ntau dua li XNUMX-stroke engine thiab emissions ntau yam teeb meem. Cov neeg siv tsheb kuj xav tias yuav ua haujlwm ntsiag to (tshwj tsis yog cov kis las kis las). Ntawm qhov tod tes, ob-stroke qauv yog nrov nrov, thiab qhov no yog ib qho kev rho tawm loj heev rau cov tswv tsheb.

Ob-stroke diesel - nws puas ua tau?

Yooj yim hauv kev tsim thiab pheej yig ob-stroke engine - lub hauv paus ntsiab lus ntawm kev ua haujlwm yog ob-stroke. Nws txawv li cas ntawm plaub-stroke engine ntawm maus taus? Koj puas muaj XNUMX stroke diesel?

Lub cav diesel yuav tsis yog ob-mob stroke. Muaj ob yam uas yuav tsum paub qhov txawv ntawm lub cav diesel thiab lub cav diesel. Thawj lub cav tseem tuaj yeem khiav ntawm cov roj diesel hauv ob lub voj voog. Txawm li cas los xij, lub voj voog diesel muaj 4 qhov kev hloov pauv: ob lub adiabatic, isochoric thiab isobaric. Yog li ntawd, cov yam ntxwv ntawm lub voj voog diesel tsuas yog ua tau rau 4-stroke units. Ob stroke diesel? Tsis muaj. Ob stroke diesel? Yog lawm.

Ob-stroke engine - dab tsi roj nws siv tau?

Ib qho nthuav tsim yog chav tsev los ntawm Cummins thiab Achates. Lub hwj chim chav tsev yog ob-stroke engine nrog 4 pistons rau 8 lub tog raj kheej. Lawv txav tawm ib leeg, thiab tag nrho cov qauv khiav ntawm cov roj diesel. Txawm li cas los xij, tom qab kev hloov kho me me, lub cav ob-stroke kuj tseem tuaj yeem khiav ntawm roj av, roj lossis hydrogen. Yav dhau los, nruab nrab siab tsim kuj tau siv los ntawm cawv thiab kerosene.

Kuv tuaj yeem nrhiav ob-stroke nyob qhov twg?

Yooj yim hauv kev tsim thiab pheej yig ob-stroke engine - lub hauv paus ntsiab lus ntawm kev ua haujlwm yog ob-stroke. Nws txawv li cas ntawm plaub-stroke engine ntawm maus taus? Koj puas muaj XNUMX stroke diesel?

Niaj hnub no koj yuav pom ib tug ob-stroke engine nyob rau hauv:

  • tshuab txiav;
  • scooters;
  • me me maus taus;
  • roj av saws. 

Interestingly, lub zog tshaj plaws nyob rau hauv lub ntiaj teb no Wartsila-Sulzer RTA96-C kuj yog ib tug ob-stroke engine thiab tsim 109 hp. Txawm li cas los xij, koj tsis zoo li yuav ntsib nws, vim nws txoj haujlwm yog los tswj cov nkoj ntim khoom. Lwm qhov tseeb nthuav yog tias chav tsev no siv lub zog hluav taws xob Common Rail. Cov txheej txheem no tau ua rau muaj kev txo qis hauv cov pa phem emissions thiab muaj kev cuam tshuam zoo rau kev tsim khoom.

Yuav ua li cas kom zoo siv lub cav ob-stroke?

Koj puas muaj txhuam hniav, scooter lossis maus taus nrog lub cav ob-stroke? Qhov tseem ceeb tshaj plaws yog xaiv cov roj. Siv ib qho kev pom zoo los ntawm cov cuab yeej lossis tshuab tsim khoom. Nws kuj tseem ceeb heev uas lub cav ob-stroke yog khiav hauv cov roj-roj sib tov nrog qhov sib txawv ntawm qhov sib txawv ntawm lub sijhawm ua haujlwm ib txwm muaj. Txwv tsis pub, lub durability ntawm kev sib txhuam cov ntsiab lus nyob rau hauv lub cav yuav txo qis heev.

Thaum ua haujlwm 2T cav, nws yog ib qho tsim nyog yuav tsum siv cov khoom sib tov hauv 14 hnub. Tom qab lub sij hawm no, cov roj uas muaj nyob rau hauv cov roj av hloov nws cov khoom lubricating thiab ua rau lub cav hnav ntau dua.Lub cav ob-stroke puas yuav rov qab los? Cummins thiab Achates tus qauv tsim yog pov thawj tias ob-stroke engine tseem tsis tau tuag. Tsis tas li ntawd, lawv yuav txuas ntxiv siv rau hauv cov tshuab dej muaj zog thiab cov khoom siv hluav taws xob me me thiab cov maus taus. Vim li no, nws yog qhov nyuaj rau kev cia siab tias lawv qhov kev txom nyem zaum kawg. Tab sis lawv puas yuav rov qab mus rau tsheb mus ib txhis? Nws yog ib qho nyuaj rau hais kom meej, tab sis lub suab nrov lawv ua feem ntau tig tawm cov neeg tsim khoom thiab cov neeg tsav tsheb.
