Ongorora Kuvandudzwa kweDiesel Generator Intake System

1, Cummins jenareta seti yakamanikidzwa mhepo yekudyara system

Turbocharging imhepo compressor inoshandisa makore eexhaust gasi kubva muinjini yekupisa yemukati kuityaira.Iyo supercharging mudziyo inogona kuvandudza kuyerera kwemhepo kupinda mucylinder nekumanikidza mweya unodiwa kupisa mafuta pasi pemamiriro ehuwandu hwekushanda uye kumhanya kweiyo. dhiziri jenareta , uye wobva wavandudza kuwanda kwesimba rejenareta redhiziri.Kuumbwa kweiyo supercharger system haingosanganisire supercharger body, intercooler, supercharger inotonhorera pombi yehardware body, asi zvakare inosanganisira iyo supercharger pressure sensor, air flow meter, speed sensor, detonation sensor, fuel injector, ignition coil uye mamwe ma sensors emagetsi echiratidzo. mhinduro.Turbocharger muviri mukuru unosanganisira exhaust bypass valve uye inlet pressure relief valve, electronic sensor feedback signal, yakadai seEMS system kuburikidza nekumhanyisa kutonga mutyairi kudiwa kwesimba rejenareta redhiziri, kuitira kuti ibudise reshiyo yebasa rekumanikidza, kudzora iyo supercharger nyaya yekupfuura. kuvhurika kwevharuvhu, kuitira kuti kuneta kwakawanda kudivi rekuburitsa turbine, wedzera kudzvanywa, ita iyo inlet kumanikidza kuzadzisa zvinangwa, Wedzera dizeli jenareta simba.Apo EMS inogamuchira motokari kubva kune imwe neimwe sensor yemagetsi haifaniri kuwedzera simba, panguva ino iyo EMS yakabuda yakamanikidzwa basa reshiyo ndeye 0, kupera kubva pakubuda kwepombi yepombi, iyo supercharger haisisiri kumanikidzirwa pakutora;EMS inodzorawo kuvhurwa kweiyo intake pressure relief valve pane supercharger kuti ikurumidze kuderedza kudzvinyirirwa kwekutora kusvika kune-non-pressurized level uye simba rejenareta dizeli kune simba rinotarisirwa.Mamiriro echisikigo e supercharger anoona iyo yakanyanya supercharger intensity.Izvo hunhu hweiyo supercharger hunosanganisira iyo yakanyanya kumhanya inotenderwa neiyo supercharger uye surge line ye supercharger.Kana imwe mhando ye supercharger yasarudzirwa jenareta redhiziri, hunhu hweiyo supercharger system inotemwa.Zvinoenderana nehupamhi hunotenderwa kumhanya kweturbocharger uye tambo yekusevha yeturbocharger, iyo yakanyanya turbocharging reshiyo pane yega yega sipidhi yemagetsi inoyerwa yedhiziri jenareta bhenji calibration.Mushure mekuenzanisa kwejenareta yedhiziri, iyo yekutanga kudzora kutungamira kweturbocharger yakatemwa.

2, Cummins   jenareta set variable valve timing system

Kana kumhanya uye mutoro wejenareta yedhiziri ichichinja, vhoriyamu yekupinda, vhoriyamu yekuburitsa, inlet uye exhaust flow velocity, nguva yekutora uye kupera simba, kupisa kwemoto mucylinder kwakasiyana, uye zvinodiwa zvechikamu chevharuvhu uye kusimudza kwevhavha zvakasiyana. zvakare zvakasiyana.Semuenzaniso: kana kukurumidza kukwira, iyo inlet flow velocity yakakwirira uye inertia simba rakakura, saka zvinotarisirwa kuti valve yekupinda ichavhurwa kare uye yakavharwa gare gare, kuitira kuti ishandise zvizere inertia yekupinza. kuyerera uye kuchaja mweya mutsva mucylinder zvakanyanya sezvinobvira;Pane zvinopesana, kana dhiziri yejenareta yakaderera, iyo inlet inoyerera yakaderera, uye inertia simba idiki.Kana vharafu inopinza yanonoka kuvhara Engle yakakurisa, gasi nyowani rapinda muhumburumbira rinosvinwa kubva muhumburumbira nepiston inokwira mukudzvanya sitiroko.Saizvozvowo, kana vharuvhu yekupinda yakavhurwa kare kare, nokuti piston iri kukwira kupera, zviri nyore kusvina gasi rekubuda mupombi yekutora, kuitira kuti gasi rinosara rinoputika mukuwedzera, asi gasi idzva rinoderedzwa, saka. kuti jenareta redhiziri harina kugadzikana.Nekuda kweizvozvo, hapana yakagadziriswa yevhavha yechikamu chekumisikidza inopa optimal performance yemajenereta edhiziri pane ese akakwira uye akaderera kumhanya.The variable valve timing (VVT) system inogona kuvandudza hupfumi hwemafuta, kushanda kwesimba uye kugadzikana kwekushanda kwemajenareta edhiziri pasi pekumhanya kwakasiyana-siyana uye mitoro nekushandura chikamu chekugovera chemagetsi edhiziri, uye kuderedza kusvibiswa kwemhepo.

3, Cummins jenareta seti yemagetsi valve tekinoroji

Diesel jenareta pamwero wakasiyana.Zvinodiwa pakufamba kwevharuvhu zvinosiyana zvakanyanya.Pakumhanya kwakaderera, nekuti vhoriyamu yekutora idiki, kana vhavha yekufamba yakakura, haizokwanise kuburitsa zvakakwana kupinza kwakashata kudzvanywa, jekiseni haigone kusanganiswa zvizere nemhepo inofemerwa mushure mejekiseni, zvichikonzera kuderera kwekupisa kushanda, yakaderera kumhanya torque ichaderedzwa zvakanyanya, uye emissions ichawedzerawo.Muchiitiko ichi, chirwere chiduku chevhavha chinofanira kushandiswa.Nekuda kwekufamba kwevharuvhu kudiki, kudzvanywa kwakashata kunowedzera, uye iyo inokonzeresa nhamba huru yevortices inogona kusanganisa zvizere musanganiswa kuti isangane neyakajairwa kushanda kwejenereta yedhiziri panguva yakaderera.Pakumhanya kukuru, mamiriro acho ezvinhu anopesana.Panguva ino, uwandu hwekutora hwakakura zvikuru.Kana kufamba kwevharuvhu kuri kudiki, kupikisa kwekutora kuchave kwakakurisa kuti kufema mweya wakakwana, zvichikanganisa kushanda kwesimba.Naizvozvo, pakumhanya kwakanyanya, zvinodikanwa kuve nekufamba kwevharuvhu hombe, kuti uwane iyo yakanakisa valve inoda.Kuderedza kushandiswa kwemafuta, BMW's inogadziriswa vharafu meshini inotungamira huwandu hwemweya mujenareta redhiziri kwete kuburikidza neiyo throttle asi kuburikidza nekusimudza kunogadziriswa kwevhavha yekudya.Kuburikidza nemagetsi anogadziriswa eccentric shaft, chiito checamshaft pane roller valve pressure rod inochinjwa nevepakati lever, zvichiita kuti inogadziriswa intake valve lift.Iyo throttle inoshandiswa chete panguva yekutanga uye nekukurumidza kushanda.Mune mamwe mamiriro ese ekushanda iyo throttle yakavhurika zvizere nekupuruzira kushoma.Tekinoroji yemagetsi tekinoroji inowana yakanakisa chiyero chesimba torque kubuda kwedhiziri jenareta pasi pemamiriro akasiyana ekumhanya kuburikidza nekugadzirisa kusingaite kwevhavha sitiroko.

Kufambira mberi kunopfuurira kwenzanga yanhasi kwakakonzerawo migumisiro yakaipa yakawanda pamhoteredzo yatinogara.Mumamiriro ezvinhu akadaro, pasi pesimba rekuvandudza kweramangwana resainzi uye tekinoroji yekugadzira seti yakaderera kabhoni, kuponesa simba, kuchengetedzwa kwezvakatipoteredza kusimudzira kwave kuita zvishoma nezvishoma, kuvandudzwa kwedhiziri jenareta yemhepo inotora system yekutsvaga, kwete kungobatsira chete. isu tinowedzera kunzwisisa kuvandudzwa kwemaitiro edhiziri generator air intake system, zvakare yenguva yemberi yekudzidza yejenereta yemhepo intake system yekuongorora inoita basa rinotungamira, Kuipa kwekushandiswa kwemafuta kwakanyanya uye kusvibiswa kwakanyanya kwemaseti ejenareta kunogona kugadziriswa nhanho nhanho.
