Yintoni ulawulo lwe-turbocharger yemoto
Indlela yokulawula i-turbocharger yemoto isetyenziswa kakhulu yinkqubo yokulawula uxinzelelo lwe-turbocharger yegesi ephumayo elawulwa ngombane. Le nkqubo yenziwe nge-valve ye-solenoid yokukhulula uxinzelelo, i-actuator ye-pneumatic, i-valve ye-bypass kunye ne-supercharger. Ulawulo loxinzelelo lwe-booster yenkqubo lwenziwa ngokuvula nokuvala i-valve ye-bypass: xa i-bypass valve ivaliwe, phantse yonke igesi ephumayo idlula kwi-booster, kwaye uxinzelelo lwe-booster luyanda; Xa i-bypass valve ivuliwe, inxalenye yegesi ephumayo ikhutshwa ngqo nge-bypass channel, kwaye uxinzelelo lwe-booster luyancitshiswa.
Ukuvulwa nokuvalwa kwevalvu ye-bypass kwenziwa yi-ECU (iYunithi yoLawulo lwe-Electronic) ngolawulo lwevalvu ye-solenoid yokunciphisa uxinzelelo kunye ne-pneumatic actuator . I-ECU ilawula uxinzelelo lwe-boost ngokwexinzelelo lwe-intake manifold, kwaye ivalvu ye-bypass ivulwa ngesantya esiphezulu kunye nomthwalo omkhulu ukuze kuthintelwe umthwalo ogqithisileyo woomatshini kunye nobushushu benjini ngesantya esiphezulu. Ukongeza, ezinye iimodeli zisebenzisa inkqubo yolawulo ye-closed-loop, nge-sensor yendawo ukondla iziphumo zokwenyani kwi-ECU, ukulungelelanisa ngokwendlela yokuphambuka, ukulawula ngokuchanekileyo i-torque yenjini .
Umgaqo osebenzayo we-turbocharger kukuqhuba i-turbine idlule kwi-exhaust gas ekhutshwa yinjini, ize icinezele umoya ongenayo ukuze kuphuculwe uxinano lomoya, ngaloo ndlela kuphuculwe ukusebenza kakuhle kokutsha kunye namandla okukhupha . I-Turbocharger isebenzisa i-inertia impulse ye-exhaust gas ekhutshwa yinjini ukuze ityhale i-turbine kwigumbi le-turbine, iqhube i-coaxial impeller ukuze icinezele umoya ungene kwisilinda, yonyusa uxinzelelo kunye noxinano lomoya, kwaye ngaloo ndlela yonyusa amandla okukhupha enjini .
Imisebenzi ephambili yee-turbochargers zeemoto ibandakanya ezi zinto zilandelayo:
Ukwandisa amandla enjini kunye ne-torque: Ii-Turbochargers zonyusa ubungakanani bomoya ongena kwisilinda, zivumela injini ukuba ifake amafutha amaninzi ngexesha elifanayo lokutshintsha, ngaloo ndlela zonyusa amandla enjini kunye ne-torque. Ngokubanzi, ii-turbochargers zinokunyusa amandla aphezulu enjini ngama-20% ukuya kuma-40%, kwaye i-torque ephezulu ngama-30% ukuya kuma-50%.
Nciphisa ukusetyenziswa kwepetroli kunye nokukhutshwa kwegesi: IiTurbochargers zinciphisa ukusetyenziswa kwepetroli kunye nokukhutshwa kwegesi ngokuphucula ukusebenza kakuhle kokutsha kwenjini kunye nokuphucula ukusebenza kakuhle kobushushu. Ngokukodwa, i-turbocharger inokunciphisa ukusetyenziswa kwepetroli kwenjini nge-5% ukuya kwi-10%, kwaye ukukhutshwa kweegesi eziyingozi ezifana ne-CO, i-HC kunye ne-NOx nako kuncitshiswe ngokufanayo.
Ukuphucula ukonga amafutha: Iinjini ezinee-turbochargers zitsha ngcono, zigcina i-3% ukuya kwi-5% yamafutha. Ukongeza, ii-turbochargers ziphucula iimpawu zokuhambelana kweenjini kunye neempawu zokuphendula okwethutyana ukuze kuphuculwe ukonga amafutha.
Ukuphucula ukuguquguquka nokuthembeka kwenjini: I-Turbocharger ingenza injini ibe kwiindawo ezahlukeneyo zokuphakama, amaqondo obushushu kunye neemeko zomthwalo ukuze igcine ukusebenza ngcono kunye nozinzo, ukuthintela amandla angaphantsi kwenjini, ukungqubana, ukugqithisa kakhulu kunye nezinye iingxaki. Kwangaxeshanye, ii-turbochargers zinokwandisa ubomi benjini kwaye zinciphise izinga lokusilela.
Umsebenzi wokuhlawula iplateau: kwindawo yeplateau, ngenxa yomoya omncinci, ukusebenza kweenjini eziqhelekileyo kuya kuchaphazeleka kwaye amandla aya kuncitshiswa. I-turbocharger inokuyilungisa ngempumelelo ilahleko yamandla ebangelwa ngumoya omncinci ngokunyusa uxinano lokungenisa.
