Electronically Controlled Common Rail System ya Dizilo Generator

Ukadaulo wapamtunda woyendetsedwa ndi njanji wapamwamba kwambiri ndiukadaulo woyendetsedwa ndimagetsi womwe umagwiritsidwa ntchito ndi makampani opanga ma dizilo kuti akwaniritse miyezo itatu yapadziko lonse lapansi.Kusiyanitsa kwakukulu pakati pa jenereta ya dizilo ya EFI ndi jenereta yachikhalidwe ya dizilo ndikuti njira yake yoperekera mafuta ndiyosiyana.Yoyamba imagwiritsa ntchito makina amafuta oyendetsedwa ndi magetsi, pomwe omaliza amagwiritsa ntchito makina opangira mafuta.Pakali pano, dongosolo lamagetsi loyendetsedwa ndimagetsi likhoza kugawidwa m'magulu atatu awa:

1. Makina amagetsi oyendetsedwa pamagetsi pamagetsi;

2. Kuwongolera magetsi kugawa mpope mafuta dongosolo;

3. Pakompyuta ankalamulira kuthamanga wamba dongosolo njanji mafuta.

Pakali pano, pakompyuta ankalamulira wamba njanji dongosolo la ma jenereta a dizilo amapangidwa makamaka ndi pampu yamafuta othamanga kwambiri, njanji yamafuta othamanga kwambiri, chitoliro chamafuta othamanga kwambiri, kulumikiza chitoliro chamafuta othamanga kwambiri, jekeseni wamafuta oyendetsedwa ndimagetsi, chitoliro chotsika chamafuta, fyuluta ya dizilo ndi thanki yamafuta.

1. Pakompyuta kulamulidwa mkulu kuthamanga mafuta mpope

(1) Pampu yamafuta apamwamba a Denso wamba njanji

Pampu yamafuta yothamanga kwambiri ili ndi mapampu awiri othamanga kwambiri, pampu yamafuta kumapeto kwa flywheel ndi mpope wamafuta kumapeto.Poyendetsedwa ndi makamera awiri (3 flanges pa cam iliyonse), mafuta ofunikira ndi silinda sikisi amaperekedwa ku njanji yothamanga kwambiri panthawi yake.

(2) Pampu yamafuta pamanja

Pampu yamafuta pamanja imagwiritsidwa ntchito kutulutsa mpweya mumayendedwe amafuta munjira yojambulira mafuta.Pampu yotumizira mafuta imakhala kumbali ya kumanzere kwa pampu ya mafuta othamanga kwambiri ndipo imaphatikizidwa ndi pampu ya mafuta othamanga kwambiri kuti ipereke mafuta ndi mphamvu inayake ya pampu ya mafuta.Matupi awiri achikasu achikasu omwe ali kumtunda kwa pampu yamafuta ndi ma valve owongolera kuthamanga (PCV), omwe amawongolera kuchuluka kwamafuta ndi nthawi yoperekera mafuta pamapampu awiri motsatana.Chilichonse mwa ma valve awiri a solenoid chikufanana ndi pulagi ya wiring, valve (PCV1) pafupi ndi flywheel ndi valve (PCV2) pafupi ndi kutsogolo.Ntchito yake ndikusintha kuthamanga kwamafuta mu chitoliro cha njanji wamba posintha kuchuluka kwa mafuta omwe pampu yamafuta imakanikizira mu chitoliro cha njanji wamba.

(3) Camshaft position sensor (G sensor)

Chojambulira cha camshaft chimagwiritsidwa ntchito kuweruza nthawi yofika yapakatikati yakufa kwa silinda yoyamba ya jenereta ya dizilo ngati chizindikiro cha jekeseni wamafuta.Sensa ya camshaft ndi ma discs awiri ofananira amaphatikizidwa mu pampu yamafuta othamanga kwambiri.Pulagi ya camshaft position sensor ili pakatikati pa kutsogolo kwa pampu yamafuta.

Plunger ikatsika, valavu yowongolera kuthamanga imatseguka, ndipo mafuta otsika amalowa m'bowo kudzera mu valve yowongolera.

Pamene plunger ikukwera, chifukwa valavu yolamulira siinapangidwebe mphamvu, imakhala yotseguka, ndipo mafuta otsika kwambiri amabwereranso ku chipinda chochepetsera mpweya kudzera mu valve yolamulira.

Nthawi yoperekera mafuta ikafika, valavu yowongolera imakhala ndi mphamvu kuti itseke, gawo lamafuta obwerera limadulidwa, mafuta omwe ali m'bowo la plunger amaponderezedwa, ndipo mafuta amalowa mu njanji yothamanga kwambiri kudzera mu valavu yotulutsa mafuta. .Gwiritsani ntchito kusiyana kwa nthawi yotseka ya valve yolamulira kuti muyang'ane kuchuluka kwa mafuta omwe amalowa mu njanji yothamanga kwambiri, kuti akwaniritse cholinga chowongolera kuthamanga kwa njanji yothamanga kwambiri.

Kamera ikadutsa pamtunda wokwera kwambiri, plunger imalowa m'malo otsika, kupanikizika kwa plunger kumachepetsedwa, valve yotulutsa mafuta imatsekedwa, ndipo mafuta amayimitsidwa.Panthawiyi, valavu yolamulira imayimitsa magetsi, ndipo ili poyera.mkombero wotsatira.

2. High kuthamanga wamba njanji chitoliro msonkhano

Chitoliro chodziwika bwino cha njanji chimapereka mafuta othamanga kwambiri omwe amaperekedwa ndi pampu yoperekera mafuta kwa ma injectors a silinda iliyonse atatha kukhazikika ndikusefedwa, ndipo amakhala ngati cholimbikitsira.Voliyumu yake iyenera kuchepetsa kusinthasintha kwapampu yamafuta othamanga kwambiri komanso kuthamanga kwamphamvu komwe kumachitika chifukwa cha jakisoni wa jekeseni iliyonse, kotero kuti kusinthasintha kwamphamvu kwa njanji yamafuta othamanga kumayendetsedwa pansipa 5MPa.

(1) Ntchito ya valavu yochepetsera njanji ndi yakuti pamene kuthamanga kwa njanji wamba kumadutsa mphamvu yaikulu yomwe chitoliro cha njanji chimatha kupirira, valavu yochepetsera njanji imatseguka kuti kuchepetsa kuthamanga kwa njanji pafupifupi 30MPa.

(2) Pali ma valve oletsa kuyenda asanu ndi limodzi (ofanana ndi kuchuluka kwa masilindala) kumtunda kwa chitoliro cha njanji wamba, omwe amalumikizidwa ndi mapaipi amafuta othamanga kwambiri a masilinda asanu ndi limodzi.Pamene chitoliro chamafuta othamanga kwambiri cha silinda inayake chikutha kapena jekeseni yamafuta ikalephera ndipo adilesi ya jekeseni yamafuta ipitilira malire, valavu yoletsa kuyenda idzachitapo kanthu kuti achepetse kutulutsa kwamafuta kwa silinda.Pali zolowera zamafuta za 1 ~ 2 kunja kwa njanji wamba, zomwe zimalumikizidwa ndi kutulutsa kwamafuta kwapampu yamafuta othamanga kwambiri.Sensor pressure pressure sensor ili kumanja kwa njanji wamba yokhala ndi cholumikizira cha harness.

3. Common njanji dongosolo kulamulira dongosolo

Dongosolo la njanji loyendetsedwa ndi magetsi litha kugawidwa m'magawo atatu: masensa, makompyuta ndi ma actuators.

Kompyutayo ndiye gawo lalikulu lamagetsi oyendetsedwa ndi njanji wamba.Malinga ndi chidziwitso cha sensa iliyonse, kompyuta imawerengera ndikumaliza kukonza kosiyanasiyana, imapeza nthawi yabwino yojambulira komanso kuchuluka kwa jekeseni wamafuta, ndikuwerengera kuti ndi liti komanso kwanthawi yayitali bwanji kuti mutsegule jekeseni wamafuta.Valavu ya Solenoid, kapena lamulo lotseka valavu ya solenoid, ndi zina zotero, kuti muwongolere bwino ntchito ya jenereta ya dizilo.Pakatikati pa dongosolo lamagetsi lamagetsi ndi ECU - unit control unit.ECU ndi microcomputer.The athandizira ECU zosiyanasiyana masensa ndi masiwichi anaika pa jenereta anapereka ndi jenereta dizilo;zotsatira za ECU ndi mauthenga apakompyuta omwe amatumizidwa kwa actuator iliyonse.

4. Wamba njanji dongosolo mafuta mafuta dongosolo

Zigawo zazikulu za dongosolo loperekera mafuta ndi pompa yoperekera mafuta, njanji wamba ndi jekeseni wamafuta.Mfundo yaikulu yogwirira ntchito ya dongosolo loperekera mafuta ndi yakuti pampu yoperekera mafuta imapangitsa kuti mafuta azithamanga kwambiri ndikuzidyetsa mu njanji wamba;njanji wamba kwenikweni ndi chitoliro chogawa mafuta.Mafuta osungidwa mu njanji wamba amabayidwa mu silinda ya jenereta ya dizilo kudzera mu jekeseni pa nthawi yoyenera.Injector yamafuta mu njanji yoyendetsedwa ndi magetsi ndi valavu ya jekeseni yamafuta yomwe imayendetsedwa ndi valavu ya solenoid, ndipo kutsegula ndi kutseka kwa valavu ya solenoid kumayendetsedwa ndi kompyuta.
