EURO emissions cov qauv yog cov txheej txheem kev cai tsim los ntawm European Union kom txwv qhov muaj kuab paug paug tawm los ntawm lub tsheb. Txhua tus qauv EURO teev cov kev txwv tshwj xeeb rau ntau yam kuab paug, xws li nitrogen oxides (NOx), cov teeb meem me me (PM), carbon monoxide (CO), thiab hydrocarbons (HC). Qhov siab dua tus lej EURO, qhov kev txwv tsis pub tshaj tawm. Nov yog qhov sib txawv tseem ceeb ntawm EURO 6, 5, 4, 3, thiab 2:
EURO 2: EURO 2 cov qauv tau qhia hauv xyoo 1996. Lawv feem ntau tsom rau kev txo cov pa roj carbon monoxide (CO) thiab hydrocarbon (HC) emissions los ntawm roj av (gasoline) xyaw thiab cov teeb meem (PM) emissions los ntawm diesel xyaw.
EURO 3: EURO 3 cov qauv tau pib siv rau xyoo 2000. Lawv ntxiv cov kev txwv ntawm CO, HC, thiab PM emissions thiab qhia thawj qhov kev txwv ntawm nitrogen oxides (NOx) emissions rau roj av thiab diesel xyaw.
EURO 4: EURO 4 cov qauv tau muab coj los siv rau xyoo 2005. Lawv txo qis NOx emissions los ntawm cov cav diesel, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau tshem tawm cov pa phem, lawv txo qis NOx emissions los ntawm cov roj av.
EURO 5: EURO 5 cov qauv tau qhia hauv xyoo 2009. Lawv ntxiv txo cov kev txwv rau NOx thiab PM emissions los ntawm diesel xyaw. Tsis tas li ntawd, EURO 5 cov qauv tau tsim cov kev txwv nruj dua ntawm cov teeb meem me me (PM) emissions los ntawm cov roj cav.
EURO 6: EURO 6 cov qauv tau siv nyob rau hauv ob theem: EURO 6a hauv 2014 thiab EURO 6b hauv 2017. Cov qauv no coj qhov tseem ceeb tshaj plaws hauv kev txo cov pa tawm mus rau hnub tim. EURO 6 tau qhia txog kev txwv nruj ntawm nitrogen oxides (NOx) emissions los ntawm ob qho tib si roj av thiab diesel xyaw, nrog rau kev txo qis ntxiv ntawm cov teeb meem (PM) emissions los ntawm diesel xyaw.
EURO 6d-TEMP thiab EURO 6d: Cov no yog qhov txuas ntxiv mus rau EURO 6 cov qauv uas tau teeb tsa txawm tias qis dua kev txwv. EURO 6d-TEMP tau tshaj tawm xyoo 2019, thiab EURO 6d hauv 2020. Cov qauv no ntxiv txo qis NOx emissions hauv ntiaj teb tiag tiag thiab suav nrog cov txheej txheem sim nruj dua kom ua raws li ntau yam kev tsav tsheb.
EURO 6d-TEMP thiab EURO 6d tau dhau los ua cov qauv emissions tam sim no thiab nruj heev, tsom mus rau kev txo cov pa phem thiab txhawb kev huv thiab ntau dua ib puag ncig cov tsheb. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias txhua tus qauv EURO siv rau ntau hom tsheb (xws li tsheb, tsheb thauj khoom, tsheb npav) thiab tej zaum yuav muaj cov hnub siv sib txawv rau cov qauv tsheb tshiab. Cov qauv EURO txuas ntxiv hloov kho los daws qhov kev txhawj xeeb loj zuj zus txog huab cua zoo thiab kev cuam tshuam ib puag ncig.
