INkqubo kaLoliwe eLawulwa ngeKhompyutha yoMbane weDizili

Itekhnoloji kaloliwe elawulwa nge-elekhtronikhi ephezulu kaloliwe eqhelekileyo bubuchwephesha obulawulwa ngombane obuqhele ukusetyenziswa lishishini lejenereyitha yedizili ukuhlangabezana nemigangatho emithathu yesizwe yokukhupha.Umahluko ophambili phakathi kwe-EFI generator ye-diesel kunye nejenereyitha yedizili yendabuko yindlela yokubonelela ngayo amafutha yahlukile.Eyangaphambili isebenzisa inkqubo ye-fuel elawulwa ngombane, ngelixa i-fuel system isebenzisa inkqubo ye-fuel mechanical.Okwangoku, inkqubo yamafutha elawulwa ngekhompuyutha inokohlulwa ibe zezi ntlobo zintathu zilandelayo:

1. Inkqubo yamafutha epompo yempompo elawulwa ngombane;

2. Inkqubo yempompo yokuhanjiswa kombane yolawulo lombane;

3. Uxinzelelo oluphezulu olulawulwa yinkqubo kaloliwe eqhelekileyo.

Okwangoku, inkqubo kaloliwe eqhelekileyo elawulwa ngekhompyutha ye iiseti generator diesel ubukhulu becala yenziwe yimpompo yepetroli yoxinzelelo oluphezulu, isiporo sepetroli soxinzelelo oluphezulu, umbhobho wepetroli woxinzelelo oluphezulu, uqhagamshelo lombhobho wamafutha oxinzelelo oluphezulu, i-injector ye-fuel elawulwa ngombane, umbhobho wepetroli ophantsi, isihluzo se-diesel kunye netanki yamafutha.

1. Ipompo ye-oyile yoxinzelelo oluphezulu olulawulwa nge-elektroniki

(1) Ipompo ye-oyile yoxinzelelo oluphezulu lwenkqubo kaloliwe yeDenso eqhelekileyo

Ipompo ye-oyile yoxinzelelo oluphezulu ineempompo ezimbini zoxinzelelo oluphezulu, impompo yeoli kwisiphelo samavili kunye nempompo yeoli ngaphambili.Iqhutywe ngeekhamera ezimbini (ii-3 flanges kwi-cam nganye), i-fuel efunwa yi-silinda-cylinder emithandathu inikezelwa kwi-high-pressure rail ngexesha.

(2) Impompo yeoli yesandla

Ipompo yeoli yesandla isetyenziselwa ukukhupha umoya kwisekethe yeoli kwinkqubo yokutofa i-fuel.Ipompo yokuhambisa ioli ibekwe kwicala lasekhohlo lompompo we-oyile ephezulu kwaye idibaniswe nepompo ye-oyile yoxinzelelo oluphezulu ukubonelela ngepetroli ngoxinzelelo oluthile lwempompo yeoli.Imizimba emibini yevalve etyheli ebekwe kwindawo ephezulu yempompo yeoli ziivalvu zolawulo loxinzelelo (PCV), ezilawula ubungakanani bonikezelo lwe-oyile kunye nexesha lonikezelo lwe-oyile kwiimpompo ezimbini ngokulandelelanayo.Nganye kwiivalvu ezimbini ze-solenoid zihambelana neplagi yokubopha i-wiring, ivalve (PCV1) kufuphi ne-flywheel kunye nevalve (PCV2) kufuphi nangaphambili.Umsebenzi wayo kukulungelelanisa uxinzelelo lwamafutha kumbhobho kaloliwe oqhelekileyo ngokulungelelanisa ubungakanani bepetroli apho ipompo yeoli icinezela khona kumbhobho kaloliwe oqhelekileyo.

(3) Isivamvo sendawo yeCamshaft (isivamvo se-G)

I-sensor ye-camshaft ye-sensor isetyenziselwa ukugweba ixesha lokufika kwe-compression top of dead center ye-cylinder yokuqala ye-generator ye-diesel njengesalathiso sokubhekisela kwi-injection ye-fuel.I-sensor ye-camshaft isikhundla kunye neediski ezimbini ezihambelanayo zesignali zihlanganiswe kwimpompo yeoli ephezulu.Iplagi ye-camshaft position sensor ibekwe embindini wempompo yeoli.

Xa i-plunger isihla, ivalve yokulawula uxinzelelo iyavuleka, kwaye i-fuel-pressure fuel flowing kwi-cavity ye-plunger ngevalve yokulawula.

Xa i-plunger inyuka, ngenxa yokuba i-valve yokulawula ayinamandla okwangoku, ikwimeko evulekileyo, kwaye i-fuel-pressure fuel flows ibuyele kwigumbi eliphantsi loxinzelelo ngevalve yokulawula.

Xa ixesha lokunikezelwa kwepetroli lifikelelwe, i-valve yokulawula inamandla ukuyivala, i-oyile yokubuyisela ijikelezo iyanqunyulwa, i-fuel kwi-plunger cavity icinezelwe, kwaye i-fuel ingena kwi-high-pressure rail ngokusebenzisa i-valve yokukhupha amafutha. .Sebenzisa umehluko kwixesha lokuvala i-valve yokulawula ukulawula inani leoli engena kwi-high-pressure rail, ukuze ufezekise injongo yokulawula uxinzelelo lomzila we-high-pressure.

Emva kokuba ikhamera idlulile ukuphakama okuphezulu, i-plunger ingena kwi-stroke ehlayo, uxinzelelo kwi-plunger cavity iyancitshiswa, i-valve yokuphuma kweoli ivaliwe, kwaye ukunikezelwa kweoli kumisiwe.Ngeli xesha, i-valve yokulawula imisa ukunikezelwa kwamandla, kwaye ikwimeko evulekileyo.umjikelo olandelayo.

2. Uxinzelelo oluphezulu lwendibano yombhobho kaloliwe oqhelekileyo

Umbhobho oqhelekileyo woxinzelelo oluphezulu unikezela i-fuel-high-pressure fuel enikezelwa yimpompo yokubonelela ngamafutha kwi-injection ye-fuel injectors ye-cylinder nganye emva kokuzinziswa kunye nokucoca, kwaye isebenza njenge-accumulator yoxinzelelo.Umthamo wayo kufuneka unciphise ukuguquguquka koxinzelelo lwe-oyile yempompo ye-oyile ephezulu kunye ne-oscillation yoxinzelelo olubangelwa yinkqubo yokutofa kwe-injector nganye, ukwenzela ukuba ukuguquguquka koxinzelelo kwi-high-pressure rail ilawulwa ngaphantsi kwe-5MPa.

(1) Umsebenzi wevalve yokunciphisa uxinzelelo lukaloliwe kukuba xa uxinzelelo lukaloliwe oluqhelekileyo lungaphezulu koxinzelelo oluphezulu olunokumelana nombhobho kaloliwe oqhelekileyo, isivalo sokunciphisa uxinzelelo lukaloliwe siyakuzivula ngokuzenzekelayo ukunciphisa uxinzelelo lukaloliwe oluqhelekileyo ukuya malunga ne-30MPa.

(2) Kukho iivalvu ezintandathu zokunciphisa ukuhamba (ezifana nenani leesilinda) kwindawo ephezulu yombhobho kaloliwe oqhelekileyo, odityaniswe ngokulandelelana kwimibhobho yeoli yoxinzelelo oluphezulu yeesilinda ezintandathu.Xa umbhobho wepetroli woxinzelelo oluphezulu lwe-cylinder ethile ivuza okanye isitofu se-fuel i-injector isilela kwaye idilesi ye-injection ye-fuel idlula umda, i-valve yokunciphisa ukuhamba iya kusebenza ukunqumla ukunikezelwa kwamafutha kwi-cylinder.Kukho i-1 ~ 2 yokungena kwe-oyile ngaphandle komzila kaloliwe oqhelekileyo, odityaniswe ngokulandelelana kunye ne-oyile yoxinzelelo oluphezulu lwempompo yeoli yoxinzelelo oluphezulu.Inzwa yoxinzelelo lukaloliwe ibekwe kwicala lasekunene lomzila oqhelekileyo kunye nesinxibelelanisi se-harness.

3. Inkqubo yokulawula inkqubo kaloliwe eqhelekileyo

Inkqubo kaloliwe eqhelekileyo elawulwa ngekhompuyutha inokwahlulwa ibe ngamacandelo amathathu: abenzi boluvo, iikhomputha kunye nee-actuators.

Ikhompyuter iyinxalenye engundoqo yenkqubo yamafutha kaloliwe alawulwa ngombane.Ngokolwazi lwenzwa nganye, ikhomputha ibala kwaye igqibezele ukusetyenzwa okuhlukeneyo, ifumana elona xesha lifanelekileyo lokutofa kunye nelona nani lifanelekileyo lokutofa kwamafutha, kwaye ibala ixesha kunye nexesha elingakanani lokuvula isitofu se-fuel.Ivalve ye-Solenoid, okanye umyalelo wokuvala ivalve ye-solenoid, njl., ukuze kulawulwe ngokuchanekileyo inkqubo yokusebenza kwejenereyitha yedizili.Ingundoqo yenkqubo yokulawula i-elektroniki yi-ECU - iyunithi yokulawula i-elektroniki.I-ECU yi-microcomputer.Igalelo le-ECU lizinzwa ezahlukeneyo kunye nokutshintsha okufakwe kwisethi ye-generator kunye ne-diesel generator;imveliso ye-ECU lulwazi lwe-elektroniki oluthunyelwa kwi-activator nganye.

4. Inkqubo kaloliwe eqhelekileyo yokunikezela ngamafutha

Amacandelo aphambili enkqubo yokubonelela ngamafutha yimpompo yokubonelela ngamafutha, isiporo esiqhelekileyo kunye nesitofu samafutha.Umgaqo osisiseko wokusebenza wenkqubo yokubonelela ngamafutha kukuba impompo yokubonelela ngamafutha icinezela i-fuel kuxinzelelo oluphezulu kwaye iyondla kumzila kaloliwe oqhelekileyo;umzila oqhelekileyo ngokwenene ngumbhobho wokuhambisa amafutha.I-fuel egcinwe kumzila oqhelekileyo ifakwe kwi-cylinder generator diesel ngokusebenzisa i-injector ngexesha elifanelekileyo.I-injector ye-fuel kwi-electronic controlled rail system yi-valve ye-injection ye-fuel elawulwa yi-solenoid valve, kwaye ukuvulwa kunye nokuvala i-valve ye-solenoid kulawulwa yikhompyutha.
