Iitreyila -ezikhenkcezisiweyo, eziyilelwe ngokukodwa ukuthutha iintlobo ngeentlobo zeempahla ezifuna ukufakwa efrijini, ziye zaba ngumdlali ophambili- kunye{2}}nomgama omde wokuthuthwa ngetsheyini ebandayo ebulela kwikhabhathi yazo ephangaleleyo, ilahleko yezothutho ephantsi, kunye nomngcipheko omncinci wokutyeba. Imfuno yemarike ihlala yomelele. Xa ukhetha isikhenkcezisi semi-itreyila, kubalulekile ukuqwalasela ngokubanzi imiba efana netreyila chassis, ikhabhathi egqunyiweyo, kunye neyunithi yesikhenkcisi ukuqinisekisa eyona ifanelekileyo.
Iitreyila -ezifakwe efrijini, ngenxa yekhabhathi ephangaleleyo, ilahleko yezothutho ephantsi, kunye nomngcipheko omncinci wokutyeba, ziye zaba ngumdlali ophambili{1}}nemgama{2}}uhambo olude olubandayo. Semi{4}}iitreyila ezifakwe efrijini, njengodidi lwelori efakwe efrijini, zidlala indima ebalulekileyo kushishino lwezothutho zamatsheyini abandayo. Ngokuyintloko zisetyenziselwa ukuthutha iimpahla ezifuna ukugcinwa kobushushu obuphezulu, njengeziqhamo kunye nemifuno, inyama yehagu, intlanzi yaselwandle, kunye nobisi. Ezi zithuthi ziyilwe ngobunono ukuhlangabezana neemfuno zabasebenzisi abohlukeneyo, ezibandakanya i-chassis yetreyila, ikhabhathi egqunyiweyo, iyunithi yefriji, kunye noluhlu lwezixhobo. Ikhabhinethi inokuxhotyiswa ngokungena komoya, ifriji, irakhi, ukuxhoma, kunye neenkqubo zokukhusela imithwalo njengoko kufuneka ukuqinisekisa ukuba iimpahla zihlala zibanda kwaye zintsha ngexesha lokuhamba.
Izizathu zokunyuka kweMfuno yeMarike
Kwiminyaka yakutsha nje, ngokunyuka kweemfuno zomgangatho womthwalo kulungiselelo kunye nokwaziswa kwemithetho emitsha yelizwe, imfuno yeesemi{0}}iitreyila ezifakwe efrijini ikhule kakhulu. Oku kuqala ngenxa yezinto ezininzi: Okokuqala, ukunyuka kweemfuno zomgangatho wemithwalo kwilizwe lonke, ngakumbi ukutya okutsha, okubangela ukuba kusetyenziswe iilori ezifakwe efrijini ukuthutha; okwesibini, ukungeniswa kwemimiselo emitsha yesizwe kuphucule ngokumandla isakhono semi{2}}erhuqwayo ukunqanda ukugcwala xa kuthelekiswa nezinye iilori ezifakwe efrijini; kwaye okwesithathu, iisemi{3}}iitreyila ezikhenkcezisiweyo zinokufikelela kwiqanda{4}}ilahleko yokuthuthwa kweziqhamo nemifuno, ngelixa zikwaphucula ukusebenza kakuhle kwamafutha kunye nokunciphisa ukuguquguquka kweqondo lobushushu kumthwalo, zehlisa kakhulu ilahleko yezothutho kunye nokuphucula ukusebenza kakuhle kwezothutho. Ngaphaya koko, uyilo olude lomzimba weetreyila{6} ezifakwe efrijini zivumela umthamo omkhulu wokulayisha, ukonga amafutha, kunye negalelo elincomekayo ekusebenzeni kakuhle kothutho ezindleleni.
