D4D cav los ntawm Toyota - koj yuav tsum paub dab tsi txog chav tsev?

Lub cev muaj zog tau tsim nyob rau hauv kev koom tes ntawm Toyota thiab Denso Corporation. Nws siv cov kev daws teeb meem uas paub los ntawm lwm lub tshuab hluav taws xob niaj hnub no. Cov no suav nrog, piv txwv li, kev ua haujlwm ntawm daim ntawv qhia hluav taws xob thaum tswj lub cav siv TCCS.

Thaum twg yog lub cav D4D tsim thiab nyob rau hauv cov tsheb uas nws siv?

Ua haujlwm ntawm D4D thaiv tau pib rov qab rau xyoo 1995. Kev faib tawm ntawm thawj lub tsheb nrog lub cav no pib xyoo 1997. Lub khw tseem ceeb yog cov teb chaws Europe, vim hais tias chav tsev tsis nrov heev nyob rau hauv Asia lossis Tebchaws Meskas, txawm hais tias Toyota muag cov tsheb feem ntau nyob ntawd.

Lub cav D4D yog siv nyob rau hauv Toyota diesel xyaw, tab sis muaj kev zam rau txoj cai no - qhov no yog rooj plaub thaum nws los txog rau cov chav uas D-CAT system siv. Qhov no yog ib qho kev txhim kho ntawm D4D system thiab kev txhaj tshuaj siab tshaj qhov qub system - 2000 bar, thiab tsis yog qhov ntau ntawm 1350 rau 1600 bar.
