Matairi mavara. Kuaverenga sei?
Kubva muna Mbudzi 1, 2012, nyika dzenhengo dzeEU dzakaunza chisungo chekumaka matayi emotokari yevafambi nezvimiti. Iwo ane graphically akafanana neaya atinoziva kubva mumidziyo yemumba.
Iwo mavara, kuburikidza neakajeka mapikicha uye chiyero chiri nyore kuzivikanwa chekuenzanisa, akagadzirirwa kubatsira vatengi kunzwisisa akakosha matayi paramita uye nekudaro kuita sarudzo ine ruzivo rwekutenga.
Pazita rega rega, tinowana mapikicha matatu ane arufabheti kana manhamba anotsanangura zvimiro zvevhiri rega rega, zvinoti:
- Kushanda kwemafuta etai (tire- rolling resistance);
- kubata kwetai nemugwagwa wakanyorova;
- iyo ruzha level inogadzirwa netai.
Mafuta ehupfumi ematairi
Inozivisa mutengi nezve kutenderedzwa kwetai, izvo zvinokanganisa kushandiswa kwemafuta. Iyo yakakwirira yekirasi yemafuta ekufambisa zvakanaka, inoderedza kushandiswa kwemafuta. Zvinofungidzirwa kuti musiyano mukushandiswa kwekirasi "A" matai uye kirasi "G" matai inofanira kukosha. kuchengetedza kwe7,5%.
Onawo: rezinesi rekutyaira. Ndinokwanisa here kuona bvunzo dzichirekodhwa?
Kuti tive nyore, tinogona kufunga kuti nekuderera kwekirasi yehuni yehuni nedhigirii rimwe chete, musiyano mukushandiswa kwemafuta uchawedzera. anenge 0,1 litres pamakiromita zana ega ega. Saka, matai emakirasi "A", "B" uye "C" anogona kuverengerwa seyakaderera kutenderera kushomeka uye kuderera kwemafuta ekushandisa, uye matai emakirasi "E", "F" uye "G" - nepamusoro pekushandisa mafuta. . Kirasi "D" ikirasi yemhando uye haishandiswe kuona matayi emotokari yevafambi.
Tire rinobata panzvimbo dzakanyorova
Sezvinoita mafuta ekufambisa zvakanaka matayi, kubatwa kwemvura kunoiswawo mumapoka uye vhiri rimwe nerimwe rine tsamba yaro. Kugoverwa kwetai rimwe nerimwe kune imwe kirasi kunoitika nekuongororwa kwakakosha uye kuenzanisa kwetai iri neinonzi "Reference tire". Musiyano unosvika pakubhuraki chinhambwe pakati peKirasi A neKirasi F matai ari vanenge 30 muzana (Makirasi "D" uye "G" haashandiswe kumatayi emotokari yevafambi). Mukuita, mutsauko webhureki chinhambwe kubva pa80 km kusvika zero pakati peClass A neClass F matayi eiyo yakajairwa compact mutakuri mota ndeye. anenge 18 metres. Izvi zvinoreva, kutaura zviri nyore, kuti nekirasi yega yega inotevera, chinhambwe chekumira chinowedzera. anenge 3,5 metres - inenge kureba kwemotokari.
Tire ruzha level
Pano, pachinzvimbo chemavara, isu tine chiratidzo chemafungu matatu eruzha uye mwero weruzha rwunoburitswa netai mu dB.
1 fala - zvinoreva yakaderera ruzha mwero (inenge 3 dB pazasi peiyo Union muganho);
2 fale -avhareji yekutinhira mwero (pakati peiyo Union muganho uye pazasi payo ne3 dB);
3 fale - inoratidza yakakwira vhoriyamu mwero (pamusoro peEU muganho).
Ruzha nhanho inoverengerwa pachikero chelogarithmic, saka yega yega 3 dB yakawanda inoreva kupetwa kweruzha rwunoburitswa. Izvi zvinoreva kuti vhiri rine kirasi ine ruzha rakanyorwa nemasaisai matatu eruzha rinenge richikwira nekana kupfuura vhiri rakanyorwa nesaisai rimwe chete.
Onawo: Maitiro ekutarisira matai ako?
