Turbocompound - chii icho? Nheyo yekushanda

Kuvandudza kushanda kwemasimba emagetsi, vagadziri vari kugadzira matekinoroji akasiyana siyana nemidziyo. Pakati pavo pane turbocompound. Ngationei kuti nderudzii rwechigadzirwa, kuti turbocompound injini inoshanda sei uye ndeapi mabhenefiti ayo.

Chii chinonzi turbocompound

Shanduko iyi inoshandiswa pane injini yedhiziri. Mune fomu yechinyakare, injini ine turbine inoshandisa gasi rekuzadza kuwedzera mweya kumanikidza mune yakawanda yekudyira.

Iyo turbine yegasi inopa zviri nani kupisa kweHTS mumasirinda, nekuda kwekuti iyo mhepo inogamuchira zvinhu zvisina kukuvadza, uye injini inowana simba rakawedzera. Nekudaro, iyi michina inoshandisa chidimbu chete chesimba rinoburitswa kana gasi rekubuda rasiya iyo yakawanda yekuzadza

Heano mamwe manhamba. Iyo yekupedza gasi tembiricha pane iyo nzira yekubuda kweinjini inogona kusvika anenge mazana manomwe emadhigirii. Gasi parinopfuura nepane turbine, rinotenderera mashizha, izvo zvinopa mota imwezve huwandu hwemhepo nyowani. Panobuda turbine, magasi achiri kupisa (tembiricha yavo inodonha nemadhigirii zana chete).

Simba rinosara rinoshandiswa neyakavakirwa dhizaini panopinda chiutsi. Chigadzirwa chinoshandura simba iri kuita chiito chema mechanical, izvo zvinowedzera kutenderera kwecrankshaft.

Kusarudzwa

Musimboti wedombo remubatanidzwa ndiko kuwedzera simba re crankshaft nekuda kwesimba rinongobviswa muchadenga mune yakajairika injini. Diesel inowedzera kuwedzera torque, asi haishandisi mafuta anowedzera.

Mashandiro anoita turbo remubatanidzwa

Classic turbocharging ine maviri maitiro. Yekutanga igasi, iyo impeller iyo inoiswa mukufamba nekuda kwekuti kumanikidza kunogadzirwa mune yekuzeya turakiti. Yechipiri mashandiro ndeye compressor inosangana neyekutanga chinhu. Chinangwa chayo kupomba mweya nyowani muma cylinders.

Pamwoyo peyuniti yekuwedzera, turbine yemagetsi inoshandiswa, iri kuseri kweiyo huru. Kuti abvise musiyano mukuru pakati pekutenderera kweiyo turbo komputa uye iyo flywheel, iyo hydraulic element inoshandiswa - batira. Kutsvedza kwayo kunovimbisa kuenderana kwetorque inouya kubva pachigadzirwa uye injini crankshaft.

Heino vhidhiyo ipfupi yekuti mashandisiro einjini dzeVolvo turbocompound anoshanda sei:

Volvo Marori - D13 Turbo Injini injini

Turbo komputa yekushanda scheme

Hechino chinokurumidza dhizaini yekuti turbo komponi injini inoshanda sei. Kutanga, gasi rekuzadza rinopinda mukati meiyo turbocharger, ichitenderera turbine huru. Kupfuurirazve, kuyerera kuno tenderedza iyo impeller yeiyi michina. Uyezve, iyo inomhanya inogona kusvika zviuru zana paminiti.

Dombo remubatanidzwa rakaiswa kuseri kwedunhu repamusoro. Rukova runopinda mukati maro, kutenderera turbine yayo. Iyi nhamba inosvika zviuru makumi mashanu nezvishanu paminiti. Tevere, iko kusanganisa kwemvura uye giya rekudzikisa rakabatana necrankshaft rinoshandiswa. Pasina kubatanidzwa kwemvura, chishandiso hachizokwanisa kupa kuwedzera kwakatsiga musimba reinjini yemukati yemoto.

Iyo scania injini ine chirongwa chakadai. Maitiro aya anoshandiswa kushandira magetsi DT 1202. Iyo yakasarudzika turbocharged dhiziri injini yakakwanisa kugadzira simba mukati me420hp. Mushure mekunge mugadziri avandudza simba remagetsi riine turbo komponi system, mashandiro ayo akawedzera nemakumi mashanu emabhiza.

Kubatsira uye kuipa

Iko kusarudzika kwekuvandudza kwehunyanzvi kwakaita kuti zvikwanisike kuwana mibairo yakanaka yakadai:

• Kuwedzera kwakadzikama mukushanda kweinjini, asi panguva imwechete iyo crankshaft haina kutenderera kupfuura zvakajairwa;
• Panguva yekushanda, kumisikidzwa hakudi kuwedzerwa mafuta, izvo zvisingaite kuti mota iwedzere kushata;
• Nekuda kwekuvapo kwe hydraulic coupling, kugadzikana kwechikwata kunovimbiswa nekuchinja kwakapinza mumutoro;
• Injini inomhanya zvakanyanya kutsetseka nekuti simba rekuwedzera rinopihwa neanoshanda crankshaft kutenderera, asi kwete nekuda kwejolts kubva kune crank mashini;
• Kugara kwechikwata hakuregi, sekunge turbine yakaiswa pane yakajairwa injini. Pane zvinopesana, nekuda kwekuburitswa kwepiston michina, zviwanikwa zvekushanda zvinowedzera.

Izvo zvinokanganisa zvinosanganisira chokwadi chekuti mari zhinji yakashandiswa mukuvandudza uye kumisikidza kwekuwedzera kunodawo kubhadhara kweinjiniya yazvino. Pamusoro pekudhura kweinjini pachayo, dhizaini yayo inova yakaoma. Nekuda kweizvi, kugadzirisa uye, kana zvichidikanwa, kugadzirisa kunodhura, uye zvinonyanya kuoma kuwana tenzi anonyatsonzwisisa chishandiso chekumisikidza.
