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 Gobisa 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 sesitofu se-fuel kwisivavanyi se-fuel, kwaye ulungelelanise uxinzelelo lwasentwasahlobo lube phezulu kancinane kunoxinzelelo oluqhelekileyo lokuvula inaliti yamafutha yesitofu samafutha (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 kwe-injini yedizili ukuze ivavanywe.

3.4 Lungisa kuxinzelelo oluchaziweyo lwenaliti yamafutha 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, le ngongoma ilandelayo kufuneka iqatshelwe:

(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 i-oyile ye-diesel ephezulu ingena esikhumbeni kwaye igeleza kwimithambo yegazi, iya kuba nefuthe eliyingozi kumzimba womntu.Ingqwalasela eyodwa kufuneka ihlawulwe ukuze ungaze uyiqwalasele ngokusondeleyo imeko yokutofa kwamafutha ukuthintela umonakalo wamehlo.
