2.5 Injini ye-TDi - ulwazi kanye nokusetshenziswa kweyunithi yedizili

Ngemva kweminyaka eminingana yokusebenza, kwaba nezinkinga ezinkulu ngohlelo lomjovo, ukuthambisa, i-ECU yeyunithi kanye nebhande elinamazinyo. Ngalesi sizathu, injini engu-2.5 TDi inegama elibi. Sethula ulwazi olubaluleke kakhulu mayelana nenjini yokukhathazeka kwa-VW.

2.5 Injini ye-TDi - idatha yobuchwepheshe

Izinhlobo ezine zalolu phiko zifakwe ezimotweni. Ngayinye yayifakwe i-turbine yejiyomethri eguquguqukayo kanye nomjovo oqondile we-Bosch onephampu yokusabalalisa elawulwa nge-elekthronikhi ekhiqize umfutho ophezulu. Amayunithi ayenomthamo wokusebenza we-2396 cm3, kanye namasilinda angu-6 V nama-valve angu-24. Bezihambisana namasondo angaphambili no-4×4 oshintshwayo noma ozishintshayo.

Izinguqulo zale yunithi namandla azo

Kodwa-ke, izinguqulo ngazinye zenjini engu-2.5 TDi zinemiphumela ehlukile. Lezi kwakuyizinjini ezingu-150 hp. (AFB/ANC), 155 HP (AIM), 163 HP (BFC, BCZ, BDG) kanye ne-180 hp (AKE, BDH, BAU). Banikeze ukusebenza okuhle kakhulu, futhi iyunithi ngokwayo yayibhekwa njengesimanje. Kube yimpendulo ezinjinini eziphambili zeMercedes neBMW.

Izixazululo zesakhiwo ezisetshenziswa kuyunithi

Kule yunithi, kukhethwe ibhulokhi ye-iron enamasilinda ayisithupha ahlelwe ku-90° V, kanye nekhanda le-aluminium alloy 24-valve elifakwe phezulu. Injini engu-2.5 TDi iphinde yasebenzisa i-balancer shaft eyayiklanyelwe ukunciphisa ukudlidliza nokugedla okuholela esikweni eliphezulu lomsebenzi.

Amaphutha kumodeli ye-2.5 TDi - abangelwa yini?

Izinkinga ezingemnandi kakhulu ezihambisana nokusebenza kweyunithi zihlanganisa ukungasebenzi kahle komjovo. Isizathu ngokuvamile kwakuwukwehluleka kwephampu kaphethiloli, i-electronics yokulawula, noma uzibuthe olawula ukulinganisa kukaphethiloli.

Lokhu kwakungenxa yohlobo lwezingxenye ezisetshenzisiwe. Iphampu yokusabalalisa i-radial izwela kakhulu ukungcola kuphethiloli kunohlobo lwe-axial. Kungenxa yalesi sizathu ukuthi ukulimala komshini ku-elementi kwenzeka kaningi.

Yini engase ibe imbangela yezinkinga?

Kuphinde kwavezwa ukuthi izinga lokufeyila kwenjini engu-2.5 TDi kungenxa yokugadwa kwezinhlelo zokukhiqiza. Ukwehluleka okuningi kufanele kubonakale kalula phakathi nesigaba sokuhlola, ngakho-ke kulindeleke ukuthi onjiniyela bakwaVolkswagen bangazinaki ngokwanele izivivinyo futhi iyunithi ayizange ihlolwe ebangeni elifanele.

Imibuzo ebalulekile kumongo wokusebenza komshini

Kuyaqapheleka ukuthi ngokulungiswa okufanele bekungenzeka ukugwema ukuwohloka okuthile, kufaka phakathi ezibizayo. Lapha sikhuluma ngohlelo lwezikhathi obeluthanda ukubhidlika ngenxa yezinga eliphansi lezinto ezisetshenziswayo. Isixazululo esihle kwaba wukushintsha ibhande lesikhathi njalo ngemuva kwamakhilomitha angama-85. km, okungaphambi kwalokho okunconywe umenzi. Uma isistimu ngokwayo iphuka, lokhu kusho ukucekelwa phansi okuphelele kweyunithi.

Uma ufuna ukuthenga imodeli yemoto enenjini engu-2.5 TDi, kungcono ukhethe imoto eyenziwe ngemuva kuka-2001. Izimo zesithuthuthu ngaphambi kwalolu suku zazibonakala ngezinga eliphakeme lokuhluleka - ngemva kuka-2001, izinkinga eziningi zaxazululwa.

Yiziphi izinguquko ezenziwe kulolu phiko?

AbakwaVolkswagen balwenze kabusha lolu phiko ukuze basuse izinkinga ezibacasulayo. Umsebenzi wawuhlanganisa ukushintshwa kwama-injection, kanye nokubuyekezwa okuphelele kwesakhiwo seyunithi, ushintsho ohlelweni lwesikhathi.

Okuvame kakhulu ukungasebenzi kahle kwenjini engu-2.5 TDi

Ukungasebenzi kahle obekuvela kaningi bekuyizinkinga ngepompo likawoyela, eliqhutshwa yi-crankshaft. Ngenkathi i-motor isebenza, i-pump drive ingase yehluleke, ishiye injini ngaphandle kokugcotshwa. Ngenxa yalokho, amathuba okuvala iphampu kawoyela ngenxa yokugqoka kwe-camshaft ayanda.

I-2.5 TDi izinjini nazo zinezinkinga nge-turbine. Lokhu kusebenza kumamodeli amayunithi asehambe ibanga elingaphezu kuka-200 km. km. Ngezinye izikhathi ukulahlekelwa okukhulu kwamandla nakho kubangelwa ukulimala kwe-valve ye-EGR kanye nemitha yokugeleza.

Yini okufanele uyibheke lapho ukhetha imoto enale yunithi?

Uma ufuna ukuthola iyunithi ongakhetha kuyo okungaba yiphutha elincane, kufanele ubheke injini engu-2.5 TDi V6 enama-155 hp. noma 180 hp Euro 3 ehambisanayo. Ukusetshenziswa kwalawa ma-motor kuhlotshaniswa nezinkinga ezingajwayelekile.

Izinjini ezingu-2.5 TDi zifakwe ezinhlobonhlobo ze-Audi A6 ne-A8, kanjalo nakwi-Audi A4 Allroad, Volkswagen Passat ne-Skoda Superb. Nakuba izimoto zihlome kahle futhi ngokuvamile zitholakala ngentengo ekhangayo, kufanelekile ukucabanga kabili ngokuzithenga, njengoba izindleko zokuzilungisa zingaba phezulu kakhulu.
