Injini ye1.4 TDi yakaiswa muVolkswagen, Audi, Skoda uye Seat motokari, i.e. vagadziri vese veboka reVW. Iyo dhiziri ine mafuta akananga jekiseni yairatidzwa nehupfumi hwakanaka, asi pakanga painewo manzwi akabatana nekuremara kunorwadza, semuenzaniso, kudengenyeka kwakasimba kana matambudziko nekugadzirisa aluminium crankcase. Kana iwe uchida kuziva zvakawanda nezve 1.4 TDi, tinokukoka iwe kuti uverenge chasara chinyorwa.

Volkswagen's TDi injini mhuri - ruzivo rwekutanga

Chimiro chehunhu ndiko kushandiswa kweTurbocharged Direct Injection tekinoroji. Turbocharged dhiziri injini zvakare ine intercooler. Zvakakosha kuziva kuti Volkswagen inovaisa kwete pamotokari chete, asiwo paVolkswagen Marine mabhoti, uyewo paVolkswagen Industrial Motor Motors units.

Yekutanga TDi injini yaive inline shanu-cylinder injini yakaunzwa muna 1989 ine Audi 100 TDi sedan. Chigadzirwa ichi chakavandudzwa muna 1999. Vagadziri vakawedzera kwairi iyo Common Rail fuel injection system. Saka zvaive neinjini yeV8, iyo yakaiswa paAudi A8 3.3 TDi Quattro. Sezvineiwo, iyo TDi injini yakashandiswa zvakare mujaho mota muchikamu cheLMP1.

Musanganiswa wematekinoroji maviri - jekiseni rakananga uye turbocharging

Muchiitiko chekutanga, mafuta ejekitori system anopfapfaidza mafuta edhiziri akananga mumakamuri makuru ekupisa. Nokudaro, imwe nzira yakakwana yekupisa inoitika kupfuura mu prechamber, iyo inonzi. jekiseni rakananga, iro rinowedzera torque uye kuderedza kubuda kwemhepo. 

Iyo turbine inofambiswa nemhepo, zvakare, inomanikidza mhepo yekupinda uye inowedzera simba uye torque mune compact, yakaderera-inotamisa unit. Pamusoro pezvo, injini dzeTDi dzakashongedzerwa neintercooler kuderedza tembiricha uye kuwedzera density yemhepo yakamanikidzwa isati yapinda muhumburumbira.

TDi ishoko rekutengesa.

Inoshandiswa nemhando dzeVolkswagen Group, pamwe neLand Rover. Pamusoro peiyo TDi kudomwa, Volkswagen inoshandisawo iyo SDi - Suction Diesel Injection yekumisikidza yemasikirwo aspirated asiri-turbo modhi ine yakananga mafuta jekiseni.

Iyi matatu-cylinder unit, iyo yakagadzirwa muna 2014 kutsiva iyo 1,2-litre modhi kubva kuEA189 mhuri, yakashandiswawo sekutsiva mana-cylinder 1,6 TDi. Sezvineiwo, chikamu chidiki chakashandisa zvimwe zvikamu kubva muinjini yechina-cylinder iyo yakadzoserwa kune matatu-cylinder system.

Iyo 1.4 TDi injini yakagadziridzwa sechirongwa chekudzikisa. Imwe yematanho yaive yekudzikisa huremu hwe crankcase uye cylinder mativi, zvinhu izvi zvakaitwa neALSiCu3 alloy yakawanikwa nekukanda giravhiti. Nekuda kweizvozvo, huremu hweinjini hwakaderedzwa nekusvika 11 kg zvichienzaniswa neyekare 1,2l TDi injini uye 27 kg yakareruka kupfuura 1,6l TDi.

Ndeapi modhi yemotokari yaive 1.4 TDi injini yakaiswa?

Zvimwe zvekugadzira zvinosanganisira mavharuvhu mana pahumburumbira, maviri DOHC camshafts, uye kushandiswa kweiyo humburumbira musoro dhizaini inowanikwa mune ina-cylinder MDB injini. Zvakare zvakasarudzwa kwaiva kutonhora kwemvura, intercooler, catalytic converter, DPF system, dual-circuit exhaust gas recirculation ine yakaderera uye yakakwira pressure EGR, pamwe neDFS 1.20 jekiseni system kubva kumugadziri Delphi.

Data yehunyanzvi - 1.4 TDi injini yakatarwa

Iyo 1.4 TDi injini inoshandisa aluminium cylinder block uye silinda. Iyo yakajairika njanji dhiziri, 4-mutsara, matatu-cylinder kumisikidzwa ine mavharuvhu mana pacylinder mune chirongwa cheDOHC. Masilinda ari mudhudhudhu ane dhayamita ye 79,5 mm, uye piston sitiroko inosvika 95,5 mm. Iyo yakazara injini inokwana 1422 cu. cm, uye compression reshiyo iri 16,1:1.

Inowanikwa mu75 HP, 90 HP modhi. uye 104hp Kuti ishandiswe zvakanaka injini, VW 507.00 uye 5W-30 oiri inodiwa. Uyezve, tangi inokwana 3,8 litres. Inofanira kuchinjwa yega yega 20 XNUMX. km.

Drive operation - ndeapi matambudziko?

Paunenge uchishandisa 1.4 TDi injini, matambudziko ane jekiseni pombi anogona kuitika. Kukanganisa kunodhura kunotanga mushure mekumhanya kweanenge 200 km. km. Kuchengeta mhete zvakare kune kukanganisa. Iyo bushings inopfeka zvakaringana nekukasira uye yakanyorwa seimwe yezvinhu zvisina kusimba zvemusangano wekutyaira. Nekuda kwavo, yakawandisa axial play ye crankshaft inoumbwa.

DPF mafirita zvakare akavharwa, izvo zvakakonzera dambudziko rakawanda pamotokari dzine yakaderera mileage. Zvimwe zvikamu zvinoda kutariswa zvakanyanya zvinosanganisira: majekiseni einjini, kuyerera kwemamita uye zvechokwadi turbocharger. Pasinei nokuti chikwata chave chiri pamusika kwenguva yakareba, kugadzirisa kwega kwega kunogona kutungamirira kumari inokosha. 

Ko 1.4 TDi isarudzo yakanaka here?

Kunyangwe makore apfuura, 1.4 TDi injini dzichiri kuwanikwa pamotokari zhinji dzakashandiswa. Izvi zvinoreva kuti kunaka kwavo kwakanaka. Mushure mekutarisa kwakadzama kwehunyanzvi mamiriro eyuniti, pamwe nemota mauri, unogona kutenga yakanaka mhando mota. Mune ino kesi, iyo 1.4 TDi injini ichave sarudzo yakanaka, uye iwe unozokwanisa kudzivirira imwe mari nekukurumidza mushure mekutenga iyo unit.
