Injini entsha ye-BENTLEY Blower Continuation
Injini yemoto yokuqala ochungechungeni lweBentley Mulliner Blower Continuation yethulwe okokuqala embhedeni wokuhlola olungiselelwe ngokukhethekile eBentley's Crewe.
I-Blower Continuation Series iwuchungechunge lwemidlalo esanda kwakhiwa engu-12 ye-Bentley edume kakhulu emlandweni, "Blower" eshibhile kakhulu engu-4½-litre eyakhelwe umjaho ngu-Sir Tim Birkin ngasekupheleni kwawo-1920. Lezi zimoto ezingu-12, ezakha uchungechunge lokuqala lomhlaba olulandelanayo lwangaphambi kwempi, sezidayiselwe abaqoqi kanye nabathandi be-Bentley emhlabeni jikelele.
Lapho i-prototype yobunjiniyela yephrojekthi - i-Car Zero - isivele isathuthukiswa, injini yokuqala yaphinde yakhiwa u-Bentley Mulliner ngosizo lochwepheshe oluvela kochwepheshe. Ngesikhathi injini isakhiwa, iqembu lonjiniyela bakwaBentley laqala umsebenzi wokulungisa omunye wemibhede yokuhlola ukuthuthukiswa kwezinjini endlunkulu kaBentley eCrewe ukuze bathole injini. Imishini yokuhlola injini itholakala e-Bentley kusukela lesi sikhungo sakhiwa ngo-1938, futhi amagumbi aqale asetshenziselwa ukuqhuba nokuhlola amandla izinjini zezindiza ze-Merlin V12 ezakhiwe yisikhungo seMpi Yezwe II Spitfire kanye ne-Hurricane fighters.
Ukulungiswa kombhede wokuhlola kubandakanye ukwenza umfanekiso ofanayo we-blower front chassis ukufaka injini, engabekwa kwi-engine elawulwa yikhompyutha dyno. Uhlobo olusha lwesoftware yokukala nokulawula injini yabhalwa futhi yahlolwa, kwavumela onjiniyela beBentley ukuthi baqaphe futhi basebenzise injini kumingcele eqondile. Ngoba ukudluliswa kweBlower kwehluka kakhulu ngosayizi nokuma kwezinjini ze-Bentley zesimanje, amabhentshi amaningi okuhlola iMerlin, asaphethwe yiBentley, asetshenziselwa ukuguqula ibhentshi lokuhlola ukuze lilingane nalezi zinjini ezikhethekile.
Lapho injini ifakwa ngokuphelele, isiqalo sokuqala senzeke emasontweni amabili edlule, kanti injini yokuqala manje isiya ohlelweni oluthile lokugqekeza ngaphambi kokuba ihlolwe ngamandla aphelele. Izinjini zizohlolwa ngaphezu komjikelezo wamahora angama-20, zikhuphuke kancane kancane zombili isivinini senjini nezimo zokulayisha kusuka kokungenzi lutho kuye ku-3500 rpm. Ngemuva kokuthi injini ngayinye isebenze ngokuphelele, kuzolinganiswa ijika eligcwele lamandla okulayisha.
Njengoba ibhentshi lokuhlola lisebenza futhi, isinyathelo esilandelayo senjini ye-Car Zero sizoba ukwethembeka kwangempela. Uma imoto isiqedile, izokwethula uhlelo lokuhlolwa kwethrekhi, ukusebenzisa izikhathi zobude obukhula kancane kancane nesivinini, ukusebenza kokuhlola nokwethembeka ngaphansi kwezimo eziyinselele kakhulu. Uhlelo lokuhlola luklanyelwe ukuzuza okulingana namakhilomitha angu-35 wamakhilomitha angu-000 okushayela amathrekhi, futhi lilingisa imibuthano edumile efana neBeijing-Paris kanye neMille Miglia.
4½ litre injini eshisiwe
Izinjini ezisanda kwenziwa zeBlower ziyizifanekiselo zezinjini ezinikeze amandla amaTeam Blowers amane uTim Birkin agijime ngasekupheleni kwawo-1920, kufaka phakathi ukusetshenziswa kwe-magnesium kukhrankcase.
Injini yeBlower yaqala impilo iyinjini engu-4½ litre enesifiso ngokwemvelo eklanywe ngu-V.O. Bentley. NjengeBentley engu-3 litre ngaphambi kwayo, i-4½-litre ihlanganise ubuchwepheshe bakamuva benjini eyodwa yosuku – i-single overhead camshaft, i-twin-spark ignition, ama-valve amane isilinda futhi, vele, amapiston e-aluminium e-Bentley manje adumile. Inguqulo yomjaho yenjini engu-4½-litre WO ithuthukiswe cishe ngu-130 hp, kodwa u-Sir Tim Birkin's Bentley Boy wayefuna okwengeziwe. I-WO ibilokhu igcizelela ukwethembeka nokucwengwa phezu kwamandla nje, ngakho-ke isixazululo sakhe sokuthola amandla engeziwe bekulokhu kuwukwandisa amandla enjini. U-Birkin wayenolunye uhlelo - wayefuna ukulayisha kabusha i-4½, futhi lo mbono, ngokusho kwe-WO, "wonakalisa" umklamo wakhe.
Ngoxhaso lwezezimali oluvela kumxhasi wakhe ocebile u-Dorothy Paget kanye namakhono obuchwepheshe ka-Clive Gallop, u-Birkin wathuma uchwepheshe weshaja enkulu u-Amherst Villiers ukuthi akhe ishaja enkulu yabangu-4½. I-supercharger yohlobo lwe-Roots—eyaziwa ngokuthi i-supercharger—yafakwa phambi kwenjini kanye ne-radiator, futhi yashayelwa isuka ku-crankshaft. Ukulungiswa kwangaphakathi enjini kwakuhlanganisa i-crankshaft entsha, enamandla, izinduku zokuxhuma eziqinisiwe, kanye nesistimu kawoyela elungisiwe.
Ngesitayela somjaho, injini entsha ye-Birkin eshajwa kakhulu engu-4½-litre ibinamandla, ikhiqiza cishe u-240 hp. Ngakho, "Blower Bentley" babeshesha kakhulu, kodwa, njengoba kubikezelwe WO, futhi ngandlela-thile buthaka. Ama-Blowers abambe iqhaza emlandweni we-Bentley, okuhlanganisa nokusiza ukuvikela ukunqoba kwe-Bentley Speed Six eshisiwe kakhulu e-Le Mans ngo-1930, kodwa emijahweni engu-12 ama-Blowers ayingenela, ukunqoba akuzange kutholakale.
