Ziziphi iingenelo ezibalaseleyo zezithuthi ze-LNG xa kuthelekiswa nezithuthi ze-CNG?

Inkqubo ye Isityalo esincinci se-LNG (isityalo esincinci se-LNG) ikakhulu ziiyunithi ezi-4 ngolu hlobo lulandelayo.

Imoto ye-LNG yenye yezona zinto zisetyenziswa kakhulu kwi-LNG fuel.

(1) Chaza ngokufutshane inkqubo yokuzaliswa kwezithuthi ze-LNG kunye nokunikezelwa kwegesi.

Impendulo: Ukuzaliswa kolwelo: I-LNG iphuma kwizibuko lokuzalisa iye phezulu kwitanki yokugcina ngevalvu yendlela enye. Igesi engaphakathi kwitanki iyaxinwa, kwaye uxinzelelo luyehla. Xa izaliswe ukuya kwinqanaba lolwelo elilinganisiweyo, iyayeka ngokuzenzekelayo;

Ubonelelo ngegesi: Xa injini iqala, ivalvu yesolenoid iyavuleka, kwaye i-LNG iphuma phantsi koxinzelelo ngaphakathi kwitanki, ingena kwi-vaporizer ukuze kutshintshiselwane ubushushu kunye negesi, kwaye inikezelwa kwinjini.

(2) Ziziphi iingenelo ezibalaseleyo zezithuthi ze-LNG xa kuthelekiswa nezithuthi ze-CNG?

Impendulo: I-LNG inobuninzi bamandla (malunga nokuphindwe kathathu kune-CNG), umgama omde wokuqhuba ongaphezulu kwe-400km, kwaye igcina amandla kakuhle kwaye ikhupha umbane omncinci.

(3) Zithini iingenelo zezithuthi ze-LNG xa zithelekiswa nezithuthi zedizili?

A. Uqoqosho. I-1m3 LNG ilingana ne-625N m3 yegesi yendalo. Ukusebenza kwezithuthi zedizili ezinamandla afanayo kubonisa ukuba i-1m3 yegesi yendalo ilingana nelitha e-1 yedizili engu-0 #, kwaye ixabiso le-1m3 yegesi yendalo limalunga ne-5.2 yuan yepetroli, eliyi-70% yexabiso lelitha e-1 yedizili engu-0 # (7.24 yuan). Oku kuthetha ukuba ukutshintshela kwigesi yendalo kwizithuthi zedizili ezinamandla afanayo kunokonga i-30% yeendleko. I-mileage yokusebenza yonyaka ibalwa ngokusekelwe kwiikhilomitha ezingama-70000 (ukusetyenziswa kwepetroli ngeekhilomitha ezili-100 kubalwa ngokusekelwe kwiilitha ezingama-50 zedizili okanye i-50m3 yegesi yendalo), enokonga i-71000 yuan kwiindleko zepetroli.

B. Ukusebenza kakuhle kokhuseleko. I-LNG ine-ignition point engama-650 ℃, iphezulu kunedizili nepetroli, kwaye kunzima ukuyitshisa kunepetroli nedizili. Umda wokuqhuma kwe-LNG yi-5% -15%, kwaye uxinano emva kokufakelwa kwegesi luyisiqingatha somoya, ngoko ke ukuba kukho ukuvuza, iya kuphuma ngoko nangoko kwaye isasazeke. Uxinzelelo lokugcina i-LNG luphantsi (0.3-0.7MPa), nto leyo eyenza ukuba ikhuseleke kune-CNG.

C. Ukhuseleko lokusingqongileyo. Ngenxa yokwakheka kwayo okucocekileyo kunye nokungcola okuncinci, izithuthi ze-LNG zikhupha iigesi ezingenabungozi kangako ezifana ne-SO2, NOX, kunye ne-CO2, eziluncedo kukhuseleko lokusingqongileyo.

D. Ithembekile. I-LNG inomsebenzi omhle wokuqalisa ubushushu obuphantsi kwaye inokonga ipetroli eninzi ngamaxesha obushushu obuphantsi. I-LNG inobuninzi bamandla, kwaye iilori ezinkulu ze-LNG zinokuhamba iikhilomitha ezingama-800 ukuya kwi-1000 ngokuzalisa ipetroli enye, nto leyo enokwanelisa iimfuno zothutho olude. Umthombo wegesi we-LNG wanele kwaye unokuthuthwa umgama omde kusetyenziswa iilori zeetanki ezizinikeleyo, ngaphandle kokuthintelwa yimibhobho yegesi yendalo.

E. Ukuguqulwa kwesithuthi se-LNG. Inani le-octane yegesi yendalo liphezulu ukuya kwi-130, kwaye ukusebenza kwayo okuchasene nokungqongqoza kulungile. Emva kokuguqulwa kwemoto, ubomi benjini bunokwandiswa ngaphezu kwezihlandlo ezi-2, kwaye iindleko zokulungisa ezifanelekileyo zingancitshiswa ngaphezulu kwe-50%. Itekhnoloji yangoku yokuguqulwa kwekhaya sele ivuthiwe, kwaye utyalo-mali ngokubanzi lufunyanwa kwiinyanga ezintandathu emva kokuguqulwa. Ukuguqulwa kwezithuthi ze-LNG kunokufezekiswa ngeendlela ezimbini: enye kukwakha kwakhona injini yedizili ekhoyo ibe yinjini yegesi yendalo kunye nokufaka inkqubo yokubonelela ngegesi ye-LNG; eyesibini kukuthenga izithuthi ze-LNG ngokuthe ngqo. Injini iguqulwe yinkampani yobungcali, iguqula injini yemoto yokuqala ibe yinjini enye yamafutha. Emva kokuguqulwa, injini inokufikelela kwinqanaba lobuchwephesha lenjini entsha, enobomi beekhilomitha ezingama-500,000.
