Umgangatho oPhezulu uMbhobho weDizili oNtsha wokuTofa iDizili DLLA144P2273 0433172273 0 433 172 273 Umbhobho wesitofu esiqhelekileyo sikaLoliwe weBosch Spare Parts

Inkqubo yokuhlola isitofu samafutha

Ukuhlolwa kwendibano yevalve yenaliti kubandakanya: ukuhlolwa kwendawo ebonakalayo, ukuhlolwa kwe-sliding, ukuhlolwa kokutywinwa kunye nokuhlolwa kokutshiza, njl.

3.1 Umphezulu we-cylindrical wesikhokelo wevalve yenaliti kunye ne-injector body mayingabi nomonakalo ocacileyo wokukhuhlana kunye nemikrwelo, kwaye indawo yokutywina iphelele.

3.2 Gobela ivalve yenaliti kwindawo engama-45 °, tsala ivalve yenaliti kumzimba wevalvu malunga ne-1/3, kwaye inokutyibilika ngokucothayo kumzimba wevalvu phantsi kwesenzo sobunzima bayo ngaphandle kwento encamathelayo.

3.3 Fakela isitofu esidityanisiweyo sesibaso kwisivavanyi sesitofu se-fuel, kwaye ulungelelanise uxinzelelo lwasentwasahlobo lube phezulu kancinane kunoxinzelelo oluqhelekileyo lokuvula inaliti yesitofu sefutha (ngokuqhelekileyo yi-12~14MPa ngaphezulu kwe-3~5MPa). Ukuba uxinzelelo lweoyile luyenyuka luye kwi-20MPa, linganisa ixesha elithatha ukuba uxinzelelo lweoyile lwehle ukusuka kwi-20MPa ukuya kwi-18MPa, hayi ngaphantsi kwe-9 ~ 12s.

Kungenjalo, ukusebenza kokutywina kumbi, kwaye akufuneki kubekho amathontsi eoyile acacileyo ajikeleze umngxuma wombhobho. Xa kungekho mvavanyi wesitofu samafutha, isitofu esilungisiweyo sesitofu sinokufakelwa ngokuthe ngqo kwimpompo yokutofa kwamafutha enjini yedizili ukuze ivavanywe.

3.4 Lungisa kuxinzelelo oluchaziweyo lwenaliti ye-petroli ye-12MPa, kunye ne-oyile yepompo kwisantya sempompo malunga nama-60 ~ 70 amaxesha / min. Isibaso esitshiziweyo kufuneka sicoleke kwaye silungelelaniswe iatom, kwaye kufuneka kubekho izandi ezinkcunkcayo nezimane zintyiloza. Akukho nto ithontsizayo ioyile, kwaye akukho kuvuza kubi kumngxuma wombhobho womzimba wesitofu.

Beka iqhekeza lephepha elimhlophe 10 ~ 20cm kude nombhobho phantsi kwesitofu, kwaye ulinganise umgama h ukusuka emlonyeni ukuya kwibala le-oyile kunye nobubanzi d bebala leoli. Emva koko ubale ngokwefomula.

Fumana i-engile ukusuka kumsebenzi we-trigonometric, kwaye kabini i-angle yi-angle ye-cone injection ye-fuel. Ukuba iimfuno azikwazi ukufezekiswa ngalo msebenzi ungentla, kufuneka kutshintshwe isitofu esitsha sesibaso.

Ekugqibeleni, kufuneka kuqatshelwe ezi ngongoma zilandelayo:

(1) Nikela ingqalelo kule khowudi ingasentla xa usebenzisa isitofu sokufutha ukuphepha ukusisebenzisa ngokungafanelekanga. Ngaphandle koko, iimfuno ezifanelekileyo aziyi kufunyanwa, i-fuel iya kutshiswa ngokungaphelelanga okanye ingatshisi, umsi omnyama uya kukhutshwa kwi-exhaust, i-fuel iya kuchithwa, kwaye amandla aya kuchaphazeleka.

(2) Xa ulungisa uxinzelelo lwenaliti yamafutha, ungaze uvumele ulusu okanye iminwe isondele kumngxuma wombhobho kwaye itofwe ngesibaso esitofwayo. Ngenxa yokuba ioli yedizili enoxinzelelo oluphezulu ingena eluswini ize iqukuqelele kwimithambo yegazi, iya kuba nefuthe eliyingozi kumzimba womntu. Ingqwalasela eyodwa kufuneka ihlawulwe ukuze ungaze uyiqwalasele ngokusondeleyo imeko yokutofa kwamafutha ukuthintela umonakalo wamehlo.
