0042 Isidibanisi esitywiniweyo se-LPG CNG yokuTshintsha i-Solenoid Coil

Ikhoyili yevalve ye-solenoid yi-29mm ukuphakama kunye ne-9mm kwi-diameter yangaphakathi.
1. Iimeko zokugweba isilaphu sekhoyili yokutshiza kaloliwe: Jonga ukuba kukho ukuvuza komoya kwingcambu yentambo yocingo nokuba ukuxhathisa kweekhoyili ezine kuphakathi kwe-9 kunye ne-3 ohms.

Okwesibini, imveliso igqunywe ngezixhobo ze-thermoplastic okanye i-flame retardant kunye ne-resin ephezulu yokumelana nokushisa, enokumelana nokushisa okuphezulu kunye nokuxhathisa ukufuma. Isetyenziswa kakhulu kwiimoto ezimbini-zamafutha e-LPG/CNG inkqubo yokulungisa, umzila kaloliwe oqhelekileyo wegesi, isixhobo sesithuthuthu, kunye nesixhobo esixhaphakileyo esisetyenziswa kwi-voltage resistor DC12V.

III: ① Ubume kunye neeparamitha zobugcisa zesitofu esiqhelekileyo sikaloliwe

1, ubume bemilo

Isetyenziswa ikakhulu kwizitofu zamafutha ezithuthi zorhwebo, ezinokuqonda iindlela ezintathu zokutofa: isitofu sangaphambili, isitofu esiphambili kunye nasemva kokutofa. Ubuninzi besitofu samafutha kunye nobude bexesha lokutofa kwepetroli kumiselwa luxinzelelo lwenkqubo kunye namandla ngexesha, kwaye ziqhutywa yiyunithi yolawulo lombane. Okwangoku, ii-injection zezithuthi zorhwebo ikakhulu kwezi fom zilandelayo;

2. Iimpawu eziphambili zobugcisa

Ukuxhathisa ikhoyili: 230mΩ

Elona xesha liphezulu lamandla: 4ms

Ubuninzi boxinzelelo lukaloliwe olusebenzayo: 1600bar

② Umgaqo osebenzayo we-injector kaloliwe eqhelekileyo

umgaqo wokusebenza

Cima (akukho naliti) = > Vula (isitofu sokuqala) = > Ukuvula ngokupheleleyo (isitofu) = > Valiwe (ukuncipha komthamo wesitofu) = > Ukuvala ngokupheleleyo (isitofu sokuyeka)

③ Ukusilela okuqhelekileyo kwezitofu zikaloliwe eziqhelekileyo kunye neendlela zabo zocalucalulo lwangaphambili.

1. Ukutya kwangaphakathi kwamafutha

njectorFault iimpawu: injini isebenza krwada, kwaye umsi omnyama uyaphuma xa ufaka amafutha emnyango;

Isizathu sokungaphumeleli: amanzi amaninzi kwisibaso;

Isisombululo: 1. Qinisekisa umgangatho wamafutha; 2. Khupha amanzi rhoqo kwaye uqinisekise umgangatho we-oil-water separator;

2. Indawo yokuhlala yangaphakathi ye-injector igugile.

Isiphoso sephutha: ukukhanya kwephutha kuvuliwe, umsi omnyama ukhutshwa xa umnyango wegesi uzaliswe, kwaye amandla awanelanga;

Isizathu sokungaphumeleli: i-fuel iqulethe inani elikhulu lamaqhekeza amahle;

Isisombululo: Qinisekisa umgangatho wesihluzo, ngakumbi umgangatho ocolekileyo wokuhluza. Fakela isixhobo sokucoca kumngxunya wokukhupha umoya wetanki yeoli ukunqanda okusingqongileyo kwangaphandle ekungcoliseni amafutha kunye nokuqinisekisa umgangatho wamafutha.

I-3, itywina yobhedu ye-gasket ayilungile, i-cylinder gas channeling.

Iimpawu zempazamo: amandla angonelanga enjini, igesi evuthayo ebalekela kwioyile yokubuya;

Isizathu sokungaphumeleli: i-gasket yobhedu yayifakwe ngamaqhekeza kwaye ayinakutywinwa;

Isisombululo: Qinisekisa ukucoceka kwe-gasket yobhedu, umngxuma wokufaka injini kunye ne-injector xa ufaka i-injector.

Igasket yobhedu ayinakuphinda isetyenziswe. UBosch ucebisa ukuba kusetyenziswe igasket enye kuphela yobhedu ukunqanda ukusebenzisa iigasket ezininzi.

4, ivalve ye-electromagnetic coil iyanyibilika

Uphawu lwesiphoso: i-injector ayikwazi ukusebenza ngokuqhelekileyo;

Isizathu sokungaphumeleli: i-coil yevalve ye-solenoid iyanyibilika ngenxa yombane ophezulu kakhulu okanye ixesha elide lamandla;

Isisombululo: Akuvumelekanga ukwenza amandla okufakelwa kwi-injector yamafutha;

5, mechanical umonakalo owenziwe ngumntu

Uphawu lwempazamo: I-injector ayikwazi ukusebenza ngokuqhelekileyo ngenxa yomonakalo womatshini, kwaye injini ayizinzile.

Isizathu sokungaphumeleli: ukusebenza okungalunganga kunye nofakelo olungenangqiqo.

Isisombululo: 1. Qinisa i-valve ye-solenoid, i-terminal kunye neplagi ye-bundle ukuphepha ukusebenza kakubi; 2. Faka i-injector yamafutha ngokungqongqo ngokuhambelana nencwadana yomyalelo;

IV: Umzobo wesakhiwo sevalve ye-solenoid yesitofu esiqhelekileyo sikaloliwe
. Ivalve yolawulo yangoku ye-solenoid itsala i-armature, kwaye i-armature iqhuba isiqu sevalve kunye nesibini sevalve yenaliti ukuvula isitofu se-fuel se-fuel injection.

Ngoko ke, ukulawula i-injector yamafutha kukulawula i-valve ye-solenoid ye-injector yamafutha. Ivalve ye-solenoid ilingana nekhoyili, eyenza amandla e-electromagnetic ngokudlula okwangoku kwikhoyili. Okukhona mkhulu umsinga, kokukhona amandla amakhulu e-electromagnetic de i-armature inokutsalwa. Kwisicelo esisebenzayo, i-injector idla ngokuvulwa ngombane omkhulu kuqala, emva koko i-valve ye-solenoid igcinwe kunye nombane ophantsi.
