Umlawuli Wokutshaja: Umlawuli Ongabonakaliyo kunye noMphenduli Wempazamo weNkqubo Yamandla Esithuthi
Kwinkqubo yamandla eyinkimbinkimbi yemoto, nangona isilawuli sokutshaja singabalulekanga njengenjini okanye ibhokisi yegiya, sidlala indima ebalulekileyo. Sifana nomlawuli ochanekileyo ohlala elungisa iiparameter ngokusekelwe kwimeko yokusebenza kwenjini ukuqinisekisa umbane ophumayo osebenzayo nozinzileyo kwisithuthi.
Umsebenzi oyintloko wesilawuli sokutshaja imoto
Isilawuli sokutshaja imoto sahlulwe ngokubanzi saba ngabalawuli bokutshaja benkqubo yamandla kunye nabalawuli besigaba senjini, nganye yenza imisebenzi yayo ukugcina ukusebenza kwesithuthi ngokuqhelekileyo.
Kwinkqubo yamandla emoto, isilawuli sokutshaja sinoxanduva lomsebenzi obalulekileyo wokuzinzisa i-voltage. Uluhlu lwesantya senjini lubanzi, kwaye i-voltage yokuphuma yejenereyitha iya kutshintsha-tshintsha ngokufanelekileyo. Izixhobo zombane ezingaphakathi emotweni, ezifana nee-headlights, iinkqubo zesandi, kunye nokuhamba kwesithuthi, zonke zifuna i-voltage ezinzileyo ukuze zisebenze ngokufanelekileyo. Isilawuli sokutshaja silawula ubungakanani bomsinga we-magnetic field ngaphakathi kwejenereyitha, sonyusa umsinga xa isantya senjini siphantsi kwaye siwunciphise xa isantya siphezulu, sizinzise i-voltage yokuphuma yejenereyitha kwixabiso elilinganisiweyo (ngesiqhelo malunga ne-14.0V) ukuqinisekisa ukuba izixhobo zombane zesithuthi azichaphazeleki kukutshintshatshintsha kwe-voltage. Kwangaxeshanye, ikwanemisebenzi yokuthintela umsinga wokutshaja ogqithisileyo kunye nokunqumla umsinga ongasemva, siphephe ukonakala kwebhetri kunye nejenereyitha ngenxa yomsinga wokutshaja ogqithisileyo, sithintele ukukhutshwa kwebhetri kakhulu kunye nomonakalo kwii-windings zejenereyitha, kwaye sandise ubomi bebhetri kunye nejenereyitha ngokufanelekileyo.
Umlawuli wesigaba senjini ugxile ekwenzeni ngcono ukusebenza kakuhle kokutsha kwenjini. Umzekelo, umlawuli wesigaba se-VVT unokulungisa isigaba se-camshaft ngokweenguqu kwiimeko zokusebenza kwenjini, ngaloo ndlela ulungisa umthamo wokungenisa kunye nokukhupha umoya, ulawula ixesha lokuvula nokuvala kunye ne-engile yeevalvu. Kwiimeko zesantya esiphantsi okanye somthwalo ophantsi, umlawuli wesigaba sokungenisa uya kuqhubela phambili ngokufanelekileyo ixesha lokuvala kwevalvu yokungenisa, edala i-intake stroke emfutshane, ephucula i-turbulence kunye ne-swirl effect kwi-cylinder, eyenza umxube ufane ngakumbi, uphucula uzinzo lokutsha, kwaye uphucule i-torque ekhawulezayo, okwenza isithuthi siqale kakuhle; xa injini ikwisantya esiphezulu okanye kwiimeko zomthwalo ophezulu, iya kulibazisa ixesha lokuvala kwevalvu yokungenisa, inyuse ubude be-intake stroke, ivumele umoya omninzi ukuba ungene kwi-cylinder, kwaye ihambelane nexesha lokufaka amafutha kamva ukwenza umxube oxineneyo, inyuse amandla enjini, ihlangabezane neemfuno zokukhawulezisa imoto okanye ukuqhuba ngesantya esiphezulu.
Iimpawu eziqhelekileyo zokusilela kwesilawuli sokutshaja imoto
Xa isilawuli sokutshaja imoto singaphumeleli, siya kubonisa iingxaki kwiinkalo ezininzi zesithuthi.
Xa isilawuli sokutshaja kwenkqubo yamandla singaphumeleli, into eqhelekileyo kukuba ijenereyitha ayivelisi umbane. Ngeli xesha, isibane sesalathisi sebhetri kwideshibhodi siya kukhanya, okuhlala kubangelwa kukonakala kwe-transistor ye-field-effect yomlawuli we-voltage okanye i-transistor yaseDarlington. Kunokubakho imeko yokuveliswa kwamandla agqithisileyo, okuya kubangela ukuba ibhetri itshaje kakhulu, okuchaphazela ubomi bebhetri, kwaye kukhokelela ekonakaleni kwebhetri, okubonakala njenge-voltage yebhetri engaphantsi kwe-10V, okwenza kube nzima kwisithuthi ukuqala. Ukongeza, i-generator regulator eyonakeleyo iya kubangela ukuba isithuthi sibe nobunzima bokukhawulezisa, ukusetyenziswa kwepetroli okwandisiweyo, kwaye kuchaphazele kakhulu ukusebenza kwesithuthi.
Ukusilela komlawuli wesigaba senjini kuya kuchaphazela ngokuthe ngqo amandla enjini kunye nokonga amafutha. Xa kwenzeka ukungasebenzi kakuhle, injini inokuba nokungahlali kakuhle, ukushukuma okukhulu, amandla ombane anganeleyo, kunye nokuqalisa kancinci kwesithuthi; kwisantya esiphezulu, amandla ombane awakwazi ukufikelela kwinqanaba eliqhelekileyo, kwaye ukusebenza kokukhawulezisa kuya kwehla. Kwangaxeshanye, ngenxa yokuncipha kokusebenza kakuhle kokutsha, ukusetyenziswa kwamafutha esithuthi kuya kwanda kakhulu, kwaye ukukhutshwa komoya ophumayo kunokugqitha umgangatho.
Ukuxilongwa kunye nesisombululo sokungaphumeleli kokulawula ukutshaja kwemoto
Kwiingxaki zokulawula ukutshaja kwenkqubo yamandla, iindlela zobuchwephesha zokufumanisa zinokusetyenziswa ukuxilonga. Umzekelo, xa kuhlolwa isithuthi, umbane we-DC oguquguqukayo we-10 - 20V (okanye 20 - 40V) ungasetyenziswa, uqhagamshelwe ngokweendlela ezithile, kwaye utshintsho lwesikhombisi semitha yangoku okanye imeko yebhalbhu iyajongwa ukulinganisa i-voltage elawulayo yomlawuli. Ukuba i-voltage ayikho ngaphakathi kwe-13.6 - 14.5V, oko kubonisa ukuba umlawuli unesiphako. Ngokubanzi, abalawuli beesekethe ezidibeneyo abanakulungiswa xa bonakele kwaye banokutshintshwa kuphela. Xa betshintshwa, kuyimfuneko ukukhetha umlawuli ofanelekileyo ohambelana nowokuqala ngokwe-voltage eqhelekileyo, i-ground polarity, kunye nezinye iinkcukacha. Amanqanaba e-voltage kunye neendlela zokumisa ze-control kunye ne-generator nazo kufuneka zihambelane.
Ukuxilongwa kwezilawuli ze-modulation phase yenjini kuyinkimbinkimbi kwaye kudla ngokufuna ukusetyenziswa kwezixhobo zobungcali zokuxilonga iimoto. Ukufunda iikhowudi zeempazamo zenjini, ukuhlalutya idatha yesigaba se-camshaft, njl. Nje ukuba impazamo ichongiwe, kwiilawuli zesigaba eziqhutywa yi-hydraulic, kunokufuneka ukujonga ukuba isekethe yeoyile ye-hydraulic ivaliwe na kwaye ukuba iringi yokutywina yonakele; kwiilawuli eziqhutywa ngumbane, kuyimfuneko ukujonga ukuba isekethe yemoto kunye nolawulo ziqhelekile na. Kwezinye iimeko, izinto zolawulo zesigaba ezonakeleyo kufuneka zitshintshwe.
Amanqaku aphambili okugcinwa kwemihla ngemihla kwee-modulators zeemoto
Ukuze kuncitshiswe ukwenzeka kokusilela kwe-modulator yeemoto, ukugcinwa kwemihla ngemihla kubalulekile. Okokuqala, kufuneka kuhlolwe rhoqo inkqubo yombane yesithuthi ukuqinisekisa ukuba iingcingo phakathi kwejenereyitha kunye nomlawuli zikhuselekile, kuthintelwe iimpazamo ezifana nokutshaja okungazinzanga ngenxa yeingcingo ezikhululekileyo. Okwesibini, ngokweemfuno zencwadi yemiyalelo yokugcinwa kwesithuthi, tshintsha rhoqo ioyile yenjini, izihluzi zomoya, njl.njl., ukuqinisekisa ukucoceka kwangaphakathi kwenjini kunye nokubonelela ngendawo yokusebenza efanelekileyo kumlawuli wesigaba. Ukongeza, xa utshintsha ibhetri okanye ijenereyitha, khetha iimveliso ezihambelana nesithuthi ukuze ungonakalisi i-modulator ngenxa yokungalingani kwe-voltage okanye ezinye iingxaki.
Njengenxalenye ephambili yenkqubo yamandla yesithuthi, ii-modulators zeemoto azinakujongelwa phantsi. Ukuqonda imisebenzi yazo, iimpawu zeempazamo, kunye neendlela zokuxilonga nezokusombulula kunokunceda abanini beemoto ukuba babone kwaye basombulule iingxaki ngokukhawuleza, ukuqinisekisa ukusebenza okuqhelekileyo kwesithuthi kunye nokwandisa ubomi baso.
