Ingaba iinjini zedizili zingawonga kakhulu amafutha?(二)
2021-08-20
Ukongiwa kwamafutha kwiinjini zedizili bekusoloko kuyinxenye ebalulekileyo yokonga iindleko, kwaye kunokuphucula ngokufanelekileyo ukusebenza kakuhle kunye nobomi benkonzo yeenjini zedizili. Kwinqaku elandulelayo, siye sachaza iingongoma ezintlanu malunga neendlela zokonga amafutha e-injini ye-diesel kunye nezilumkiso, kwaye ilandelayo iseleyo, kunye neendlela ezisebenzayo kakhulu.
6) Lungisa uxinzelelo lwenaliti ye-fuel ye-injector yamafutha. Umzekelo, uxinzelelo lwe-peel injection (12.0 + 0.05) MPa ye-injector ye-fuel injini ye-diesel ye-195, xa uxinzelelo lwe-fuel injection lungaphantsi kwe-10.0MPa, ukusetyenziswa kwamafutha kuya kunyuka nge-10 ~ 20g / (kW. ), indlela yokuthelekisa ingasetyenziselwa ukujonga nokulungelelanisa uxinzelelo lwenaliti. Uxinzelelo kwimpompo yeoli.
7) Jonga rhoqo kwaye ugcine into yokucoca umoya. Ukuba isihluzo somoya singcole kakhulu, ukungena komoya kuya kungonelanga. Isiphumo siyafana nesiphumo esingalunganga sokususwa kwevalvu. Oku kuya kukhokelela ekusetyenzisweni kwamafutha enjini ye-diesel okwandisiweyo, umbane ongonelanga kunye nokusilela komsi omnyama.
8) Xa injini ye-diesel isetyenziswa, zama ukuba ungaqhubeki ngesantya esiphezulu kunye nomthwalo ogcweleyo kangangoko kunokwenzeka. Ngokubanzi, iinjini zedizili zinoluhlu olusebenzayo ngokwezoqoqosho. Isantya esilinganisiweyo siphawulwe kwi-nameplate ye-injini, kwaye ngokohlalutyo lwe-curve yeempawu ze-injini ye-diesel, isantya seyona ndlela ilungileyo yokusebenza kwezoqoqosho malunga ne-85% yesantya esilinganisiweyo. Ngeli xesha, amandla / iyure ukusetyenziswa kwepetroli yeyona iphantsi kwisantya sonke. I-tachometer ye-injini ye-diesel iphawulwe ngendawo eluhlaza, ngokuqhelekileyo indawo yokusebenza kwezoqoqosho kwi-injini ye-diesel.
9)Ukulawula ubushushu bamanzi okupholisa. Ubushushu bamanzi obuphantsi kakhulu okanye obuphezulu kakhulu bunokubangela ingozi enkulu kwiinjini zedizili. Xa ubushushu bamanzi buphantsi kakhulu ngexesha lokusebenza, ukuchithwa okuhambelanayo kweendawo ezihambayo ze-injini ye-diesel kuya kutshintsha kakhulu kwi-design clearance, eya kwandisa ukuchasana nokuqhuba kunye nokukhawulezisa ngokukhawuleza ukunxiba kwe-injini ye-diesel. (Umzekelo, xa ubushushu bamanzi bungaphantsi kwe-30℃, bungaphezulu kwamaxesha ama-5 okuguga okuqhelekileyo, okuya kwandisa ukusetyenziswa kwamafutha nge-15%). Ukuba ukushisa kwamanzi kuphezulu kakhulu, kuya kubangela ukuba i-injini ye-diesel igqithise, itshintshe i-gap yecandelo ngalinye, ibangele uchungechunge lweengxaki ezifana nokuhla koxinzelelo lweoli, i-piston enamathela kwi-cylinder, ukuhla kwamandla, njl. gcina ubushushu bamanzi buhamba kuluhlu lwe-80 ~ 90℃.
10) Faka isixhobo sokufudumeza injini ye-diesel kwi-injini ye-diesel. Ukusebenzisa iinjini ze-diesel ebusika, ukwenzela ukugcina ioli kunye nokunciphisa ukusetyenziswa kwamandla, i-injini ye-diesel ifakwe ngaphambili ngombhobho wokukhupha ukunyusa ukushisa kwedizili kunye nokunciphisa i-viscosity ye-diesel, ukwenzela ukuba i-diesel i-atom kwaye itshiswe ngokwaneleyo. Oku kunokunciphisa kakhulu ukusetyenziswa kwamafutha nge-5% ~10%. Olona luhlu lobushushu bobushushu bedizili bungama 66~75℃, kwaye isiphumo sesona singcono.
