2024 Tus sau: Erin Ralphs | [email protected]. Kawg hloov kho: 2024-02-19 16:10

Thaum lub sijhawm saib xyuas cov khoom siv uas khiav ntawm lub cav ob-stroke, cov lus nug feem ntau tshwm sim txog kev siv cov roj thiab lubricants, roj, thiab lwm yam. Daim ntawv thov raug, xaiv thiab cov hauv paus ntsiab lus ntawm kev siv 2T roj yuav tham ntxiv..

yam ntxwv dav dav

Thaum ib chav yuav khoom nrog lub cav ob-stroke, nws yuav tsum tau muab kev saib xyuas kom raug. Cov chav no suav nrog:

• chainsaw;
• scooter;
• motokosa;
• boats;
• lwm.

Qhov no yog cov txheej txheem uas muaj zog ceev thiab lub teeb yuag yog cov yam ntxwv tseem ceeb. Txhua tus neeg yuav khoom xav kom cov khoom siv yuav khoom siv tau ntau xyoo, tsis txhob poob rau lub sijhawm. Tab sis nws nyob ntawm kev saib xyuas kom raug ntawm lub cav. Yog li ntawd, muaj 2T-semi-synthetic roj, ntxhia thiab hluavtaws hom uas muaj high-class compositions. Lawv yog tsim los siv nyob rau hauv ob-stroke roj av cav.

Qhov txawv ntawm cov cav

Ob-stroke roj yog qhov sib txawv ntawm plaub-stroke formulations. Qhov no tau piav qhianta ntawm cov qauv ntawm mechanisms. Lub cav roj av ob-stroke tsis muaj qhov tsim nyog lubrication system. Cov roj yog ntxiv rau lub tank roj, qhov twg nws yog tov nrog roj av thiab ces muab tso rau hauv lub cav. Nws yog tus yam ntxwv los ntawm tag nrho cov pa taws uas tsis muaj combustion. Vim nws cov tshuaj muaj pes tsawg leeg, cov khoom sib tov yooj yim nrog cov sib tov sib xyaw.

2T roj tau noj ib txhij nrog roj. Txawm hais tias ib feem me me ntawm nws yog emitted nrog cov pa pa hauv daim ntawv ntawm cov roj pos huab. Hauv cov qauv qub ntawm xws li cov cav, cov txheej txheem sib xyaw ua tiav manually. Ib koob tshuaj ntawm 1:20 txog 1:100 yog siv. Cov chav tshiab tshiab twb tau siv tshuab tsis siv neeg dosing. Cov tshuab zoo li no yuav siv cov roj nyob ntawm seb lub nra ntawm cov khoom siv. Ua tsaug rau cov txheej txheem tshiab, kev siv roj kuj tau txo.

Tsis zoo li yav dhau los muaj pes tsawg leeg nyob rau hauv plaub-stroke engine, cov roj loj yog poured rau hauv ib tug cais compartment. Cov roj no muaj ntau yam additives uas txhim kho lub cev thiab kev ua haujlwm ntawm cov khoom. Yog li ntawd, nws yog txwv tsis pub siv lawv nyob rau hauv ib tug ob-stroke engine. Txwv tsis pub, deposits yog tsim rau ntawm qhov chaw ua hauj lwm, lub tog raj kheej-piston pawg. Qhov no ua rau kev tawg, nrog rau txhaws ntawm chav tsev.

Daim ntawv thov

Feem ntau rau cov tshuab ob-mob stroke ib txwm siv, lub carburetor roj xa system yog siv. Ib txhij muab cov roj thiab tshem tawm ntawm lub tog raj kheej yog vim li cas txog 30% ntawm cov sib tov nkag mus rau hauv lub cev tsis hlawv. Lawv raug tso tawm nrog cov pa pa.

Qhov no yog qhov tsis zoo ntawm ob lub tshuab hluav taws xob. Piv nrog rau ib nrab combustion ntawm cov roj nyob rau hauv plaub-stroke engine, 2T hom roj ua rau muaj teeb meem emissions, smog, thiab pa luam yeeb. Yeej, cov phenomena tshwm sim nyob rau hauv cov teb chaws Es Xias vim yog oversaturation ntawm txoj kev nrog maus taus nrog ob-stroke engine.

Tsis ntev los no, muaj kev hloov pauv hauv kev tsim khoom. Cov kev tsis txaus no tau txais txiaj ntsig zoo heev los ntawm qee qhov kev tshawb fawb txog kev txhim kho ntawm ob-stroke engines. Qhov tshiab indirect roj txhaj system pom qhov txo qis hauv emissions, txo roj noj.

ob-stroke roj yuav tsum

Rau qhov ua tau zoo thiab kev ua haujlwm zoo ntawm cov cuab yeej, nws yog qhov yuav tsum tau siv cov roj zoo dua. Cov ntsiab lus tseem ceeb uas ua kom zoo yog cov khoom sib xyaw tshwj xeeb rau 2T roj. Lawv raug xaiv rau txhua hom cav, suav nrog qhov yuav tsum tau siv.

Zoo ib yam li plaub-stroke engine blends, ob-stroke roj yog formulated nrog anti-hnav additives. Ua tsaug rau cov khoom siv tshuaj, lawv tiv thaiv cov hlau. Mineral roj 2T muaj ib yam tshwj xeeb ntawm additives los txhim kho ib puag ncig tus phooj ywg.

Rau kev ua haujlwm ntev ntawm lub cav, qee qhov yuav tsum tau muab tso rau pem hauv ntej rau roj. Lawv yuav tsum muaj:

• lubricating thiab tiv thaiv hnav;
• ntxuav muaj nuj nqi;
• tiv thaiv kev tsim cov pa phem hauv cov pa tawm;
• tso tseghaus luam yeeb;
• zoo sib xws rau kev sib xyaw nrog roj txawm tias qhov kub thiab txias;
• tiv thaiv corrosion siab;
• zoo fluidity;
• kev ua tau zoo ib puag ncig.

Nyob rau hauv cov ntaub ntawv no, muaj pes tsawg leeg yog zoo. Nws tiv thaiv lub cev muaj zog ntawm qhov tsis zoo.

Hom thiab kev faib tawm

Hnub no, 2T roj muab faib raws li lawv lub hom phiaj. Muaj cov sib xyaw ua ke uas tuaj yeem siv los ntawm cov tshuab hluav taws xob qis qis rau cov maus taus ua haujlwm siab. Lawv raug faib feem ntau raws li API tus qauv. Nws suav nrog cov chav kawm hauv qab no:

• TA - lubricating roj rau cov tshuab cua txias me me (mopeds, chainsaws, thiab lwm yam).
• TB yog cov roj nplua nyeem pom zoo rau cov tshuab cua txias.
• TC - cov roj tsim los rau cov chav tsev uas xav tau siab. Lawv siv cov roj nplua nyeem ntau (mob lub tsheb kauj vab, snowmobiles thiab lwm lub tsheb uas tsis yog lub nkoj tsav tsheb).
• TD - cov ntaub ntawv tsim los rau cov chav nyob sab nraud, cov nkoj ua dej txias.

Txij li thaum pib xyoo 1993, TC thiab TD APIs tau ua haujlwm tawm. Ntawm cov ntsiab lus muag, 2T roj nrog cov yam ntxwv ntawm cov hom yav dhau los tseem pom.

Tom qab ua kev tshawb fawb hauv cov chaw pabcuam hauv St. Petersburg, cov kws tshaj lij tau xaus lus tias hauv 90% ntawm cov neeg mob, qhov tsis ua haujlwm ntawm chav tsev yog cuam tshuam nrog kev hnav ntawm qhov chaw ntawm lub hauv paus cua sov. Cov teeb meem lubrication yog feem ntau ua rau tawg. Yog li ntawd, nws tsim nyog muabua tib zoo saib xyuas cov roj xaiv.

Producers

Cov kws tshaj lij sau tseg cov tuam txhab nrov tshaj plaws ntawm cov roj cav ob-stroke, uas tau ua pov thawj lawv tus kheej hauv kev lag luam ntawm qhov zoo vim lawv qhov zoo thiab kev ntseeg siab. Cov no suav nrog Husqvarna, Hitachi, ECHO, ALCO, Stihl. Tus nqi ntawm 2T roj (synthetics) yog hais txog 300-500 rubles / l. Semi-synthetics nqi 250-400 rubles / l, thiab ntxhia muaj pes tsawg leeg - 150-250 rubles / l.

Tom qab xav txog cov yam ntxwv ntawm cov roj rau ob-mob stroke engine, koj tuaj yeem xaiv txoj cai muaj pes tsawg leeg rau kev tu lub cav.
