Nabani na othanda ubunjineli beemoto kufuneka akhulule umnqwazi aye kwaMazda. Ngezixhobo ezinqongopheleyo kuninzi lwabavelisi kwihlabathi liphela- abathi baxhathise intsebenziswano yamaqela ukufikelela kuqoqosho olukumgangatho ophezulu-iMazda iyaqhubeka nokucwangcisa indlela yayo ngokuzimeleyo. Iphuhlisa amaqonga ayo, iinjini zayo, izisombululo zayo. Kwaye konke oku ngaphandle kokubhenela kwiinkonzo zezinye iimpawu. Kuyaphawuleka, akunjalo?
Kodwa iMazda yaya nangakumbi. Xa bonke abanye abavelisi babheje ekunciphiseni umthamo weenjini (okuthiwa ukunciphisa), usebenzisa i-supercharging kunye neenkqubo zokutofa ngokuthe ngqo, iMazda yagcina ukufuduka kweenjini zayo kwaye yasungula isizukulwana esitsha sepetroli ye-SKYACTIV yeenjini zomoya ezibheja kwelinye icala: ukunciphisa ilahleko yamandla. ngenxa yokhuhlane kunye nokwanda komlinganiselo woxinzelelo. Bonke bathi: indlela ayiyo le Mazda. Kodwa kwafika ixesha lokungqina uphawu lwaseJapan lulungile: emva kwayo yonke loo nto, ukuhla bekungeyompendulo.

Isiphumo? I-Mazda iyaqhubeka nokubeka iirekhodi zokuthengisa ngokupheleleyo kuzo zonke iimarike kunye nokutsho ukuba ngaphambi kokufakelwa kombane kwimoto, kusekho indlela ende yokuhamba kwiinjini zokutsha ngokubhekiselele ekusebenzeni kakuhle. Njengoko besixele kule veki, iMazda ifuna ukulinyusa izinga kwakhona.Uyathanda?
Ukuphunyezwa kwisizukulwana esilandelayo seenjini zepetroli ze-SKYACTIV (ezinokufikelela kwimarike kwangoko ngo-2018) iteknoloji yeHCCI, emele "I-Homogenous Charge Compression Ignition", okanye "Ignition by compression with homogeneous charge". Ngobu buchwepheshe, ukutshiswa kwamafutha kuphunyezwa ngomlinganiselo ophezulu woxinzelelo lwe-injini, ukuphelisa iiplagi zentlantsi zemveli ukuqalisa ukudubula komxube. Okanye ngamanye amazwi, uxinzelelo kumxube lunjalo kangangokuba lubangela ukuvutha kwayo.
Ngokusisiseko, oku yinto esele yenzeka kwiinjini ze-Diesel, ezisebenza ngakumbi kuneenjini ze-petroli zendabuko ngokubhekiselele kusetyenziso lwamandla, kodwa kwelinye icala zingcolise ngakumbi (ngenxa yeegesi eziveliswa kukutsha kwedizili).
Xa kuthelekiswa neenjini ze-diesel, enye inzuzo yeenjini ze-HCCI kukuba ayifuni i-injection ngokuthe ngqo okanye iinkqubo zikaloliwe eziqhelekileyo: i-fuel ifafazwe kwigumbi lokutshisa ngamanani amancinci kwaye i-homogeneously - eyona nto ibalulekileyo yokuchithwa kwepetroli ngokulinganayo. Bona umfanekiso ongezantsi:
Iimpawu ezininzi sele zizamile ukuphumeza le teknoloji kwiinjini zabo zokuvelisa: i-Nissan, i-Opel (GM), i-Mercedes-Benz kunye ne-Hyundai. Zamile zonke kodwa akukho nanye ephumeleleyo.
Kuyabonakala ukuba, i-Mazda ikwazile ukunyusa umlinganiselo wokunyanzeliswa kweenjini zayo ze-HCCI ukuya kwixabiso eligqithisileyo elimele ukuba lisondele kwi-18: 1. Ngokuthelekisa, ii-injini zedizili zine-avareji yoxinzelelo lwe-16: 1, ngelixa kwi-injini yepetroli yesintu la maxabiso ahluka phakathi kwe-9: 1 kunye ne-10.5: 1 (kuxhomekeke ekubeni i-atmospheric okanye i-turbo).
Phawula: Umlinganiselo wokunyanzeliswa ubhekisa kwinani lamaxesha umthamo womxube wamafutha omoya wesilinda uxinaniswe kwigumbi lokutsha phambi kogqabhuko-dubulo.
Izinto eziluncedo kule nkqubo
Ngokutsho kwe-Mazda, ukusebenza kunye ne-HCCI detonation endaweni yokusebenza ngokutshisa kwendabuko kunciphisa ukuya kwi-30% yokuveliswa kwe-NOx ekutshani. Kwaye ayisiyiyo nje into ekhutshwayo eyehlayo, ukusetyenziswa nako kuyancipha - amaxabiso, njengoko sisazi, angadityaniswanga.Le vidiyo yeGeneral Motors ibonisa indlela esebenza ngayo inkqubo yeHCCI:
Iingxaki, iingxaki, iingxaki
Ngokwethiyori, umgaqo ulula: umlinganiselo woxinzelelo oluphezulu + umxube olinganayo = ukusebenza kakuhle kunye nokutshisa okucocekileyo. Umgaqo ulula kodwa ukuphunyezwa kunzima.
Ukuze le nkqubo isebenze ngokuchanekileyo, isofthiwe kunye ne-hardware ekwazi ukubeka esweni ukushisa kwigumbi lokutsha, ukujikeleza, i-injection ye-fuel kunye nokuvulwa kunye nexesha lokuvala i-valve iyafuneka. Kuntsonkothe kakhulu ukuthelekisa zonke ezi zinto ngexesha lokwenyani, kugcina umsebenzisi ethandeka. Iimpawu ezininzi zizamile, akukho namnye ophumeleleyo.
Enye ingxaki kukusebenza okubandayo, ngelixa igumbi lokutsha alifiki kubushushu obufanelekileyo bokusebenza, ukutsha akuqhelekanga.
Kubonakala ngathi i-Mazda, ngokungafaniyo neempawu esele zikhankanyiwe, ikwazi ukucombulula zonke ezi ngxaki. Uyathanda? Siza kufumanisa kungekudala. Injongo ye-Mazda kukuba isizukulwana esilandelayo se-Mazda3 siya kufika sele sixhotyiswe ngeenjini ze-SKYACTIV HCCI, imodeli ecwangciselwe ukuqaliswa kwangoko ngo-2018.
Nangona kunjalo, sinethemba lokuba iMazda ayilibali ngale njini kwakhona…
