Txawm hais tias cov tsheb niaj hnub no tuaj yeem ua tau yooj yim nce mus txog 50mpg ntawm txoj kev tsheb, cov tsheb thauj khoom (lwm lub npe hu ua HGVs thiab artics) ua tiav tsis muaj dab tsi zoo li ntawd. Hauv xyoo 2003, cov ntaub ntawv los ntawm Lub Tsev Haujlwm Saib Xyuas Kev Thauj Khoom tau pom tias qhov nruab nrab 'mais ib nkas loos' ntawm artic hnyav tshaj 33t yog 7.6mpg. Nyob rau hauv 2015, tus naj npawb ntawm cov roj siv tau dhia mus rau 7.9mpg, nce ntxiv ntawm 0.3mpg. Thiab, rau cov neeg ntawm koj lub hlwb ua haujlwm hauv litres / 100km, txhais tau hais tias lub tsheb thauj khoom niaj hnub siv 29.774 litres roj ib 100km. Rau cov neeg ntawm koj uas txaus siab, koj tuaj yeem nyeem cov ntaub ntawv luam tawm DFT rau koj tus kheej ntawm no.
Nrog rau qhov kev tshwm sim saum toj no uas artics rov qab zoo li kev lag luam roj tsis zoo, tej zaum koj yuav xav tsis thoob vim li cas qhov ntawd yog qhov xwm txheej thaum txawm tias cov tsheb muaj kuab paug tshaj plaws ntawm kev ua lag luam ua tiav kev lag luam roj zoo dua. Zoo, muaj ob lub laj thawj tseem ceeb rau qhov no:
1. Cov log tsheb muaj qhov hnyav heev los rub
6-axle lorries tuaj yeem hnyav txog 44-tonnes, thaum ntau dua 2-axle tsheb thauj khoom (nrog 3-axles ntawm lub trailer) tuaj yeem hnyav txog 40-tonnes. Muab piv rau cov niaj hnub diesel saloon xws li BMW 320d, uas muaj qhov hnyav tag nrho ntawm 2.105-tonnes, thiab koj tuaj yeem pom yog vim li cas qee lub cav tsheb, xws li cov los ntawm Scania, muaj peev xwm txog li 14.0-liters nrog lub zog loj. - kom lawv tuaj yeem rub qhov hnyav uas lawv nqa nrog, tsis hais txog kev ua haujlwm.
2. Tsis muaj kev nyuaj siab rau kev lag luam kom cov lorries ua haujlwm zoo dua
Lwm yam uas yuav tsum tau nco ntsoov yog tias thaum lub tsheb tuam txhab lag luam nyob rau hauv lub zog loj los ntawm EU los ua kom lawv lub tshuab ua haujlwm zoo dua, cov tuam txhab tsheb tsis yog. Yog li ntawd, feem ntau cov tuam txhab tsheb tau ditched loj, ib txwm aspirated cav nyob rau hauv kev pom zoo ntawm me me, turbo petrol xyaw (piv txwv li Ford nrog lub 1.0 EcoBoost, txawm hais tias qee cov tuam txhab tsis tau ua raws li, piv txwv li Mazda nrog lawv 2.0 SKYACTIV cav).
Piv nrog rau lub siab uas cov tuam txhab tsheb nyob rau hauv kev txhim kho kev ua tau zoo thiab txo qis emissions, cov tuam txhab tsheb thauj khoom muaj tsawg heev.
Qhov ntawd tuaj yeem hloov sai sai, vim tias hauv Tebchaws Meskas, Lub Chaw Tiv Thaiv Ib puag ncig (EPA) thiab National Highway Traffic Safety Administration (NHTSA) tau teeb tsa cov cai tshiab hauv xyoo 2016 los txo cov tsheb emissions thiab roj siv. Cov kev cai no xav kom cov tuam txhab lag luam txo qis 25 feem pua ntawm lawv cov tsheb tshiab. Cov tswv yim zoo sib xws tuaj yeem tsim rau UK, thiab EU, nyob rau lub sijhawm kom txo qis emissions. Tam sim no, emission qauv rau cov tsheb thauj khoom hauv EU tau txhais los ntawm lub tshuab hluav taws xob tso zis thiab g / kWh.
