Ichitevera nyika dzakawanda dzeEurope, hurumende yeRussia ichangobva kuita kuti mafuta edhiziri ekirasi yechipiri zvisiri pamutemo. Izvo izvi zvakabatana nei uye chii chinonzi hazard class diesel fuel, ichakurukurwa munyaya yanhasi.

Tembiricha yemhando yemafuta edhiziri

Nekuda kwekuti mafuta edhiziri ane parafini, inoomesa pazasi-zero tembiricha, iyo (mafuta) inokamurwa zvichienderana nemamiriro ekunze. Imwe neimwe yezvikamu zvinotevera ine yayo yekusefa tembiricha.

  • Kirasi A +5° C.
  • Kirasi B0° C.
  • Kirasi C -5° C.
  • Kirasi D-10° C.
  • Kirasi B -15° C.
  • Kirasi B -20° C.

Zvinokosha kucherechedza kuti kune nzvimbo uko tembiricha ambient inogona kuwira pasi pepamusoro parameters, mamwe makirasi anopiwa - kubva 1 kusvika 4. Izvi zvinotevera: kirasi, cloud point uye filterability.

  • 0:-10° C, -makumi maviri° C;
  • 1:-16° C, -makumi maviri° C;
  • 2:-22° C, -makumi maviri° C;
  • 3:-28° C, -makumi maviri° C;
  • 4:-34° C, -makumi maviri° C.

Zvinoitika kuti kana uchishandisa mafuta edhiziri munzvimbo dzakasiyana dzemamiriro ekunze, haufanirwe kunetseka zvachose nezvekuti ichatonhora uye, semhedzisiro, basa rakakosha richakundikana.

Makirasi engozi

Ikozvino GOST inopa makirasi matatu ane ngozi yezvinhu zvinokuvadza.

Pano ivo ndevaya:

  • I kirasi - ine ngozi zvikuru;
  • II kirasi - zvine mwero ngozi;
  • III - njodzi yakaderera.

Uye tichifunga nezvekuti tembiricha yemafuta edhiziri panguva yekupenya inodarika 61° C, inorongedzerwa sechinhu chakaderera-chengozi (kureva, kukirasi VI). Zvinoda kuziva kuti zvinhu zvakaita semafuta egasi kana mafuta ekudziya zvakare ndezvechikamu chimwe chete. Mushoko rimwe chete, mafuta edhiziri haana kuputika.

Zvimiro zvekufambisa uye kushanda

Diesel mafuta anogona kutakurwa chete pamotokari yakagadzirirwa chinangwa ichi, iyo iyo mvumo yakakodzera yakapihwa. Mukuwedzera, kana pakaitika moto, michina yakadaro inofanira kuva nemidziyo yakakodzera yekudzima moto. Chekupedzisira, mapasuru ese anofanirwa kumakwa zvakanaka - UN No. 3 kana OOH Nha.

Mumamiriro ezvinhu akajairwa, mafuta edhiziri anobatidza zvisina kunaka patembiricha yakaderera, kunyanya kana ichienzaniswa nemamwe masanganiswa anopisa - semuenzaniso, nepeturu. Asi muzhizha, apo tembiricha yakadzikama inogona kusvika pakupera kwegore, zvinokurudzirwa kubata mafuta edhiziri zvakanyanya. Kunyanya kana iwe uchireva mavhoriyamu makuru emafuta.

cetane number

Iyi nhamba inoonekwa sechiratidzo chikuru chekupisa kwemafuta uye inosarudza kugona kwayo kupisa, nguva yekunonoka (nguva iri pakati pejekiseni nekudzima). Zvese izvi zvinokanganisa kumhanya kwekutanga injini, pamwe nehuwandu hwekubuda kwemhepo. Iyo yakakwirira nhamba, zvakanyanya kutsetseka uye zvinobudirira mafuta edhiziri anopisa.

Panewo chinhu chakadai secetane index. Inoreva kusanganiswa kwezvinowedzera kuwedzera chiyero checetane. Zvakakosha kuti mutsauko pakati penhamba uye index ishoma, sezvo zvakasiyana-siyana zvinowedzera zvinokanganisa kemikari yemafuta edhiziri nenzira dzakasiyana.

Fuel classifications

Munguva pfupi yapfuura, hurumende yeRussian Federation yakasaina chibvumirano chekushandira pamwe neEuropean Union maererano neindasitiri yekuchenesa oiri. Ichi ndicho chikonzero icho cheEuropean classification yezvinhu zvinopisa zviri kuuya kuRussia zvakarongeka.

Ziva kuti nhasi kwatove ne2 zviyero:

  • mudzimba GOST;
  • European kana, sezvainodanwawo, Euro.

Izvo zvine hunhu kuti mazhinji ezviteshi zvekuzadza zvinopa data pamafuta edhiziri panguva imwe chete mune ese ekutanga neyechipiri sarudzo. Asi, kutaura chokwadi, zviyero zviviri izvi zvinoteedzerana mune zvese, saka kune muridzi wemota anoziva GOST, zvichave nyore kujairana neEuro.
