Akụkụ ụgbọ ala maka Dongfeng Cummins ihe mmetụta nrụgide oriri 4921322

Ihe mmetụta nrụgide zuru oke (MAP).

Ọ na-ejikọta ihe oriri na-eri ihe na tube na-adịghị ahụ ọkụ, na ibu nke ngwa ngwa dị iche iche nke engine, ọ na-achọpụta mgbanwe mgbanwe na ntinye ihe oriri, wee gbanwee ya na mgbama voltaji site na mgbanwe nke nguzogide n'ime nke ihe mmetụta maka ECU iji dozie ya. ọnụ ọgụgụ ịgbanye mmanụ ọkụ na akụkụ mgbanye oge.

Na engine EFI, a na-eji ihe mmetụta nrụgide oriri na-achọpụta ụda ikuku nke oriri, nke a na-akpọ D-ụdị injection system (ụdị njupụta ngwa ngwa). Ihe mmetụta nrụgide ikuku na-achọpụta olu ikuku n'ụzọ na-edoghị anya kama ọ bụ ihe mmetụta ikuku na-erute ozugbo. N'otu oge ahụ, ọ na-emetụtakwa ọtụtụ ihe, ya mere enwere ọtụtụ ọdịiche dị n'etiti nchọpụta na nlekọta nke ihe mmetụta ikuku nke oriri, na mmejọ nke ya kpatara nwekwara ihe pụrụ iche.

Ihe mmetụta nrụgide oriri na-achọpụta nrụgide zuru oke nke ọtụtụ ihe oriri n'azụ trottle. Ọ na-achọpụta mgbanwe nke nrụgide zuru oke na manifold dị ka ngwa ngwa na ibu nke engine si dị, wee gbanwee ya na voltaji mgbaàmà ma ziga ya na njikwa njikwa engine (ECU). ECU na-achịkwa ọnụọgụ ntụtụ mmanụ ọkụ dịka voltaji mgbama siri dị.
