Ngaphandle kwamanqaku akhankanywe apha ngasentla, iimfuno zokuchaneka zifuna ingqalelo yakho kwiimpazamo ezahlukeneyo ezamkelekileyo. Ukunyamezela impazamo encinci kuyafuneka kumashishini akhethekileyo afana neekhemikhali kunye nemveliso yamayeza. Uxinzelelo kunye namaqondo obushushu yimida ekukhetheni iimitha zokuhamba ezifanelekileyo, nazo. Iimitha kufuneka zixhathise kwiimeko ezigqithisileyo ngaphandle kokuthotywa kwentsebenzo kwizicelo zoxinzelelo oluphezulu. Kuthetha ukuba ukugcina ukuthembeka kweemitha zokuhamba kwiimeko ezinjalo kubalulekile ekusebenzeni kwexesha elide.

Imingeni kuMlinganiso wokuHamba kwerhasi

Irhasi yendalo, njengomthombo wamandla acocekileyo, iya isetyenziswa ngokunyukayo, kunye nomlinganiselo wayo kulwakhiwo lwamandla onyuka ngonyaka. Ngophuhliso lweProjekthi yoMbhobho werhasi eNtshona-Mpuma eChina, ukugqunywa kwerhasi yendalo kuyakhula, nto leyo eyenza umlinganiselo wokuhamba kwerhasi yendalo ibe linyathelo elibalulekileyo.

Okwangoku, umlinganiselo wokuhamba kwerhasi yendalo usetyenziswa ikakhulu kwiindawo zokuhlala zorhwebo, kwaye umlinganiselo e-China uxhomekeke ikakhulu kwimitha ye-volumetric. Igesi yendalo inikezelwa ngeendlela ezimbini ngokubanzi: igesi yendalo yombhobho (PNG) kunye negesi yendalo ecinezelweyo (CNG).

Ezinye iimitha zenziwe ngokweemfuno ezithile, njengokugqithisileyoumthamo ophantsi kunye ophezulu. Isilinganisi-manzi esivumela amazinga okuqukuqela aqhelekileyo kunye nencopho iqinisekisa ufundo oluqhubekayo noluchanekileyo. Ubungakanani obuncinci okanye obukhulu ngomnye umba ofanele ukuqwalaselwa ngokukodwa ukufaneleka kwecandelo ngalinye lemitha yokuhamba.

Umgaqo wokuSebenza

Imitha yerhasi yendalo isebenza ngokulinganisa ubuninzi berhasi ethunyelwa ngombhobho. Ngokuqhelekileyo, izinga lokuhamba ngumsebenzi wesantya segesi kunye nommandla onqamlezayo wombhobho. Ubalo luqhuba nge-algorithms ephucukileyo, apho iipropati eziguquguqukayo zegesi yendalo zahluka ngobushushu, uxinzelelo kunye nokwakhiwa kolwelo.

Ukusetyenziswa kweemitha zokuHamba kwegesi
