2-stroke rov qab cav? Tej zaum, hais tias tus thawj coj technical ntawm Formula 1

Anonim

nrhiav ob stroke engine nyob rau hauv tsheb peb yuav tsum rov qab mus rau ib tug ntev txoj kev nyob rau hauv lub sij hawm - ib tug ntawm cov zoo-paub piv txwv yog lub me me ob- thiab peb-lub tog raj kheej DKW. Niaj hnub no nws yog ib hom cav uas yog qhov tseem ceeb nyob rau hauv me me maus taus, nyom mowers, nkoj me, thiab lwm yam.

Kuj tseem muaj ob lub tshuab hluav taws xob sab hauv combustion loj, qhov tseeb, ib qho loj tshaj plaws, yog tias tsis yog lub tshuab hluav taws xob loj tshaj plaws hauv lub ntiaj teb yog lub cav ob-stroke: Wärtsilä-Sulzer 14RT-flex96C.

Tseem muaj kev sim rov ua dua tshiab nyob rau xyoo 90s, thiab ntau qhov qauv tau nthuav tawm hauv qhov kev taw qhia, piv txwv li, los ntawm Ford thiab BMW, tab sis lawv yuav raug tso tseg rau ib qho laj thawj nkaus xwb: emissions.

2-stroke engines.

ob strokes plaub strokes

Ob-mob stroke engine yog li hu ua, raws li lawv ua tiav combustion ntawm ib tug huab cua-fuel-filled lub tog raj kheej nyob rau hauv ib lub kiv puag ncig, tsis zoo li plaub-stroke engines (tus qauv niaj hnub no), uas yuav tsum tau ob revolutions ua li ntawd.

Sau npe yuav mus rau peb tsab ntawv xov xwm

Lawv muaj ntau qhov zoo dua li plaub-mob stroke engine: lawv yooj yim dua thiab sib dua, lawv yooj yim dua los tswj, lawv tau txais ntau lub zog rau lub cav plaub-stroke ntawm qhov sib npaug, thiab lawv tuaj yeem ua haujlwm hauv txhua txoj haujlwm vim tsis muaj kev txhawj xeeb txog. roj ntws (Lubrication yog ua los ntawm kev sib xyaw roj nrog roj thiab lawv tsis muaj li qub).

Tab sis raws li peb tau hais, lawv cov emissions yog ib qho ntawm lawv cov teeb meem loj tshaj plaws. . Qhov no yog vim nws txoj haujlwm uas, raws li tau hais los saum toj no, lub cav yog lubricated los ntawm kev sib xyaw cov roj nws tus kheej nrog cov roj, ua kom pom tseeb cov roj ntsha uas raug tshem tawm los ntawm cov pa tawm, ntxiv rau cov roj tseem tsis raug hlawv.

Qhov rov qab los?

Ob-mob stroke engine zoo li yuav tsum tau doomed, txawm nyob rau mopeds, tab sis nyob rau hauv xyoo tas los no peb tau pom ib tug resurgence ntawm cov no, tshwj xeeb tshaj yog nyob rau hauv ob lub log. Cov hom xws li KTM tau nyob rau hauv pem hauv ntej ntawm ob-stroke engine evolution, qhia technologies xws li kev txhaj tshuaj ncaj qha roj.

Cov kev tsim kho tshiab no, ntawm lwm tus, ua rau ob lub tshuab hluav taws xob rov qab los thiab txawm tias tshaj plaub lub tshuab hluav taws xob hauv emissions thiab txawm tias muaj txiaj ntsig, yog li muaj kev tsom mus rau cov hom cav no ... txawm tias hauv Formula 1.

Qhov ntawd yog qhov peb khaws los ntawm cov lus ntawm Pat Symonds, Formula 1 tus thawj coj ua haujlwm, ntawm lub rooj sib tham ntawm lub zog ntawm Motorsport Industrial Association.

Raws li nws, tej zaum txoj kev zoo tshaj plaws rau lub neej yav tom ntej ntawm Formula 1 powertrains yuav pw hauv ob lub tshuab hluav taws xob (ib qho kev ntsuas raug txiav txim siab rau cov chav kawm tseem ceeb ntawm Moto GP ib yam) - hloov, yog tias txhua yam mus raws li qhov xav tau, tuaj yeem tshwm sim. thaum ntxov 2025:

Ntau npaum li cas, lub suab zoo los ntawm cov pa tawm, thiab ntau yam teeb meem nrog rau ob lub sij hawm qub tsis cuam tshuam rau hnub no. Kev txhaj tshuaj ncaj qha, supercharging thiab cov tshuab hluav taws xob tshiab tau ua rau cov ntaub ntawv tshiab ntawm ob lub tshuab hluav taws xob kom ua tau zoo thiab muaj txiaj ntsig zoo heev. Kuv xav tias yuav muaj yav tom ntej zoo rau lawv.

Tab sis peb yuav tsum tsis txhob xav txog hluav taws xob?

Formula E, ua los ntawm 100% hluav taws xob ib leeg-seaters, tau ntes tag nrho cov xim, muab lub ntsej muag ntawm lub neej yav tom ntej ntawm kev huv thiab kev ua haujlwm zoo motorsport yuav ua tau.

Pat Symonds ntseeg hais tias, thaum tuav cov thawj koom ruam ntawm combustion engines (tam sim no ib feem ntawm electrified), nyob rau hauv lub caij tom ntej Formula 1 yuav raug txiav txim siab (ntxiv) "ntsuab" ua tsaug rau kev siv cov hluavtaws hluavtaws - twb tau tham nyob rau hauv lub tsheb vim li cas - uas ua ke. carbon dioxide (CO2) ntes los ntawm huab cua nrog hydrogen.

Lub neej yav tom ntej ntawm Formula 1 tuaj yeem yog, yog li, nrog ob lub tshuab hluav taws xob, nrog Symonds kuj tseem hais txog qhov muaj peev xwm ntawm cov cav nrog cov pistons opposite (raws li kev tawm tsam ntawm cov thooj voos kheej kheej) - nrog kev ua haujlwm ntawm ib ncig ntawm 50%. Los ntawm nws qhov kev xav, lub cav combustion sab hauv tseem muaj lub neej yav tom ntej ntev:

Tsis muaj dab tsi tsis ncaj ncees lawm nrog lub tshuab hluav taws xob, tab sis muaj cov laj thawj vim li cas lawv tsis yog qhov kev daws teeb meem rau txhua tus. Internal combustion engine muaj lub neej yav tom ntej ntev. Lub neej yav tom ntej uas ntev dua li ntau tus neeg ua nom tswv xav, vim tias cov nom tswv tau twv txhua yam ntawm lub tsheb hluav taws xob. Kuv xav tias muaj qhov ua tau zoo heev uas yuav muaj lub tshuab hluav taws xob sab hauv. Tab sis tej zaum nws ua haujlwm ntawm hydrogen.
