Hnub no, muaj ntau yam khoom siv rau kev pabcuam lub cev muaj zog. 2T roj yog tus cwj pwm los ntawm cov khoom tshwj xeeb. Yuav tau tham ntxiv.

cov ntaub ntawv dav dav

scooters feem ntau yog muab faib ua ob pawg. Lawv tuaj nrog ob-mob stroke thiab plaub-stroke engine. Txhua pawg muaj nws qhov zoo thiab qhov tsis zoo. Kev hloov pauv tsis tau.

Hauv ob lub tshuab hluav taws xob, roj av, roj thiab oxygen hlawv ib txhij hauv chav roj. Nrog plaub-stroke engine, txhua yam yog yooj yim. Nws tsuas yog tsim nyog los saib xyuas cov roj. Ob-stroke hom yog capricious heev. Nyob rau hauv cov ntaub ntawv no, tshwj xeeb yuav tsum tau muab tso rau pem hauv ntej rau qhov zoo ntawm 2T roj.

Kev faib tawm

Muaj peb hom 2T lub cev muaj zog roj: hluavtaws, semi-synthetic thiab ntxhia. Nyob rau hauv xyoo tas los no, kev ua lag luam tau nce conquered los ntawm cov roj hluavtaws. Nws yog qhov xav tau tsawg tshaj plaws ntawm kev ua haujlwm (kub qhov sib txawv). Nws yog ib qho tseem ceeb uas cov khoom sib txuas emit ib qho me me ntawm cov kua qaub thaum lub sij hawm combustion, uas nyob rau ntawm lub muffler thiab cov ntaub ntawv soot nyob rau hauv lub cav chamber. Raws li qhov yuav tsum tau ua ntawm tus qauv API, 2T lub cav roj tau muab faib ua hom hauv qab no:

1. Rau lub cavmopeds, nyom mowers thiab lwm yam cav tov. Lawv raug TA.
2. Rau cov maus taus uas tsis muaj zog thiab lub cev muaj zog. Marked as TV.
3. Rau av raws cov cav. This is TS.
4. Rau cov motors sab nraud. Marking TD.

Ntxiv rau, muaj ob qho qauv ntxiv rau kev txiav txim siab cov khoom ntawm cov roj nplua nyeem - JASO thiab NMMA. Raws li thawj qhov kev faib tawm, tag nrho cov roj tuaj yeem muab faib ua pawg hauv qab no: FA, FB thiab FC. Lawv txawv ntawm cov pa luam yeeb tsim tawm. Qib FA muaj qhov tseem ceeb tshaj plaws.

Raws li qhov thib ob, kev saib xyuas yog them rau cov txheej txheem tseeb ntawm decomposition ntawm cov roj residues thiab tseem haus luam yeeb tiam. Tus qauv no txawv ob pawg ntawm cov khoom sib xyaw: TC-W2 thiab TC-W3. Ib tug niaj hnub muaj pes tsawg leeg yog TC-W3.

Nws yog ib qho tseem ceeb heev uas yuav tau xaiv lub tshuab ntxhua khaub ncaws kom raug. Txhua lub chaw tsim khoom ntawm cov khoom siv no tsim cov qauv raws li cov qauv tsim. Tsuas yog qee hom lubricants yuav tsum tau ntxiv rau hauv lub cev.

Ob-stroke oil properties

Rau qhov tsis muaj teeb meem, siv sijhawm ntev, cov txheej txheem xav tau cov roj zoo. Cov cim tseem ceeb uas 2T roj rau lub scooter yuav tsum muaj yog:

• tiv thaiv hnav kev ua haujlwm;
• muaj peev xwm lubrication;
• pa luam yeeb;
• qis deposits;
• roj txuas ntawm txhua qhov kub;
• fluidity thiab corrosion resistance.

Cov roj huv rau ob lub tshuab hluav taws xob tsis yogsiv. Feem ntau nws ib feem ntawm tag nrho cov huab hwm coj yog los ntawm 85 mus rau 98%. Lwm cov khoom xyaw yog ntau yam additives uas kuj yog siv rau plaub-stroke engine. Cov tshuaj ntxiv tau nkag rau hauv cov roj kom tau txais qhov kev ua tau zoo.

Ntxiv

Txhua yam khoom siv esters ntxiv rau 2T roj rau lub scooter lossis lwm yam khoom siv nrog lub cav ntawm cov qauv tsim kom tau txais cov yam ntxwv xav tau. Qhov no yog cov khoom siv biodegradable. Qhov kev ua tau zoo no tsis yog cov hom hydrocarbon.

Ob-stroke engine oil additives raug xaiv raws li kev ua haujlwm. Siv cov khoom tiv thaiv hnav. Lawv pab tiv thaiv cov hlau los ntawm kev puas tsuaj. Ua ke nrog zinc-raws li additives, ash-free additives nyob rau hauv daim ntawv ntawm esters thiab phosphoric acids yog siv.

Ob lub xab npum-dispersant thiab phenolic formulations yog siv los ua additives kom lub cav huv si thiab txo cov build-up nyob rau hauv lub combustion chamber. High molecular hnyav tebchaw kuj pom lawv daim ntawv thov rau ntxiab cov kab mob. Ntau yam antioxidants uas inhibit cov tshuaj tiv thaiv ntawm kev txhim kho corrosion, anti-foam additives feem ntau ntxiv rau cov muaj pes tsawg leeg. Polybutylene tau ntxiv los txo cov tailpipe emissions.

Kev tshuaj xyuas

2T roj hluavtaws yog qhov zoo tshaj plaws hnub no. Kev txhim kho tsis tu ncua, kev txhim kho ntawm cov tshuab tsim khoom tso cai rau ua tiav ntau duakev ua haujlwm siab nyob rau hauv kev sib piv nrog cov ntxhia muaj pes tsawg leeg. Yog li ntawd, niaj hnub no cov nyiaj no tsuas muaj ib qho txiaj ntsig - tus nqi.

qhov txiaj ntsig no yog qhov ua tau zoo los ntawm kev ua tau zoo. Cov hmoov tshauv ntxiv, ua rau cov nyiaj tso cia, degrades lub cav ua haujlwm hauv lub sijhawm luv luv. Cov muffler deteriorates, carbon deposits tshwm nyob rau hauv lub pistons thiab rings nyob rau hauv lub combustion chamber. Vim li no, compression poob, uas txhais tau hais tias lub zog txo.

Txhawm rau zam qhov xwm txheej zoo li no, nws yog ib qho tsim nyog yuav tsum tau ntxuav txhua qhov ntawm cov kua qaub. Tag nrho cov no tuaj yeem zam tau los ntawm kev siv roj nrog cov khoom ntxiv.

Kev tshuaj xyuas cov neeg siv khoom

Saib ntawm kev tshuaj xyuas ntawm 2T roj uas cov neeg yuav khoom tawm mus, peb tuaj yeem hais tias cov khoom sib xyaw zoo ntawm cov khoom nruab nrab thiab cov nqi siab saib xyuas cov kab ke. Ntxiv rau tus nqi, cov roj hluavtaws tsis muaj qhov tsis zoo. Koj muaj peev xwm yuav xws li ib tug muaj pes tsawg leeg ntawm tus nqi ntawm 300-450 rubles / l. Nws yuav tsum tau borne nyob rau hauv lub siab hais tias kev siv cov ntxhia roj ua rau ghostly txuag. Txij li kev kho me me thiab kho loj thaum siv cov roj ntxhia yuav xav tau cov nqi nyiaj txiag loj.

Nws hloov tawm tias cov khoom siv hluavtaws ntawm cov roj tso cai rau koj kom ua tau raws li cov kev cai ntawm kev siv tshuab hauv cov roj lubrication zoo. 2T hluavtaws roj yog ruaj khov thiab xis nyob. Txawm li cas los xij, thaum xaiv qhov tsim nyog muaj pes tsawg leeg, cov lus pom zoo ntawm cov chaw tsim khoom yuav tsum raug coj mus rau hauv tus account. Nws txoj haujlwm ruaj khov nyob ntawm nws.

Tom qab xav txog cov yam ntxwv thiab cov caikev xaiv cov roj nplua nyeem rau lub tshuab ob-mob stroke, txhua tus tuaj yeem xaiv qhov muaj pes tsawg leeg rau lawv cov khoom siv.
