3975375 Pump injection mmanụ ụgbọala dabara maka akụkụ Cummins QSL9 Engine

Enwere ụdị sekit njikwa mgbapụta mmanụ mmanụ atọ: sekit njikwa mgbapụta mmanụ ọkụ na-achịkwa ECU, sekit njikwa mgbapụta mmanụ ọkụ na-achịkwa, yana sekit njikwa mgbapụta mmanụ na njikwa ọsọ.

1.ECU na-achịkwa sekit njikwa mgbapụta mmanụ

(1) Mgbe agbanyere mgba ọkụ ọkụ, nke ugbu a na-aga site na eriri relay isi, kọntaktị na-emechi, na ọkụ ọkụ na-enye EFI ike.

(2) Mgbe injin malitere, a na-ejikọta ọnụ na-amalite ngwaọrụ (ST) nke mgba ọkụ ọkụ, na eriri L2 na sekit relay relay na-agba ume, nke na-emepụta suction iji mechie kọntaktị nke sekit relay relay.A na-enye ọkụ eletrik na mgbapụta mmanụ ọkụ, a na-etinyekwa mmanụ ọkụ na-arụ ọrụ.

(3) Ozugbo a malitere engine ahụ, ihe mmetụta ọsọ ga-etinye akara ọsọ engine Ne n'ime ECU.N'oge a, transistor VT na ECU na-agbanye, na eriri L1 na sekit relay relay na-enye ume, nke mere na kọntaktị ya na-anọgide na-emechi, na mmanụ ụgbọala mgbapụta na-aga n'ihu na-arụ ọrụ.

(4) Mgbe injin ahụ kwụsịrị ịrụ ọrụ, a na-ewepụ VT, a na-ewepụ kọntaktị relayer sekit, eriri ọkụ nke mgbapụta mmanụ ọkụ na-akwụsị, na mgbapụta mmanụ ọkụ na-akwụsị ịrụ ọrụ.

2. Mgbanwe na-achịkwa mgbapụta mgbapụta mmanụ ọkụ

(1) Gbanyụọ mgbanaka ọkụ, a na-emechi kọntaktị relay isi, na ọkụ ọkụ na-enye ike na usoro EFI.

(2) Mgbe ị na-amalite, a na-ejikọta ọkụ ọkụ ọkụ na njedebe ST, a na-eme ka ọkpụkpụ relay relay L2 na-eme ka ọ dị ike, na-emechi kọntaktị kọntaktị relayer, na mmanụ ọkụ na-amalite ịrụ ọrụ.

(3) Igwe ahụ na-agba ọsọ, ikuku na-abanye n'ime injin ahụ na-esi na mita ikuku eruba.Efere nha na mita ikuku na-agbagharị na-atụgharị, na-agbanye ọkụ mgbapụta mmanụ ọkụ, na eriri L1 nke mgbanaka sekit na-amalite inwe ume.

3. Ogwe njikwa mgbapụta mmanụ ọkụ na njikwa ọsọ

(1) Mgbe injin ahụ na-arụ ọrụ na obere ọsọ ma ọ bụ ọkara na obere ibu, a na-agbanye transistor dị na ECU, a na-agbanyekwa eriri mmiri nke mgbapụta mgbapụta mmanụ ọkụ, na-eme ka kọntaktị B mechie.N'ihi resistor etinyere n'usoro na sekit, mgbapụta mmanụ na-arụ ọrụ na obere ọsọ.

(2) Mgbe injin na-agba ọsọ na nnukwu ibu na ibu dị arọ, a na-ebipụ transistor dị na ECU ma mechie kọntaktị A.A na-ejikọta mgbapụta mmanụ ọkụ ozugbo na ọkụ ọkụ ma na-agba ọsọ ọsọ ọsọ.
