Yintoni iAutomotive turbocharger control
Indlela yokulawula ye-automobile turbocharger ibonwa ikakhulu yinkqubo yokulawula uxinzelelo lwegesi ye-turbocharger elawulwa ngombane. Inkqubo yenziwe nge-valve ye-solenoid yoxinzelelo, i-actuator ye-pneumatic, i-valve ye-bypass kunye ne-supercharger. Ukulawulwa koxinzelelo lwenkqubo ye-booster kufezekiswa ngokuvula nokuvalwa kwe-valve ye-bypass: xa i-valve ye-bypass ivaliwe, phantse yonke i-gesi yokukhupha igeleza nge-booster, kwaye uxinzelelo lwe-booster luyanda; Xa i-valve ye-bypass ivuliwe, inxalenye yegesi yokukhupha ikhutshwe ngokuthe ngqo kwi-channel bypass, kwaye uxinzelelo lwe-booster luyancitshiswa.
Ukuvulwa kunye nokuvalwa kwe-valve ye-bypass kufezekiswa yi-ECU (i-Electronic Control Unit) ngokulawulwa kwe-valve ye-solenoid yoxinzelelo kunye ne-actuator pneumatic . I-ECU ilawula uxinzelelo lokunyusa ngokoxinzelelo lwendlela yokuthatha, kwaye i-valve ye-bypass ivuliwe ngesantya esiphezulu kunye nomthwalo omkhulu ukunqanda umthwalo ogqithiseleyo kunye nobushushu be-injini ngesantya esiphezulu. Ukongezelela, ezinye iimodeli zisebenzisa inkqubo yokulawula i-loop evaliweyo, ngokusebenzisa i-sensor ye-position ukondla iziphumo zangempela zokubulawa kwi-ECU, ukulungelelanisa ngokuphambuka, ukulawula ngokuchanekileyo i-torque ye-injini.
Umgaqo osebenzayo we-turbocharger kukuqhuba i-injini yomoya ngokusebenzisa igesi yokukhupha ekhutshwe yi-injini, kwaye emva koko ucinezele umoya othathayo ukuphucula ukuxinwa komoya, ngaloo ndlela kuphuculwe ukusebenza kakuhle kokutsha kunye namandla aphumayo. I-Turbocharger isebenzisa i-inertial impulse ye-exhaust gas ekhutshwa yi-injini ukutyhala i-injini yomoya kwigumbi le-injini yomoya, iqhubela i-coaxial impeller ukucinezela umoya kwi-cylinder, yonyusa uxinzelelo kunye nokuxinana komoya, kwaye ngaloo ndlela yonyusa amandla aphumayo enjini.
Imisebenzi ephambili yee-automotive turbocharger ibandakanya le miba ilandelayo:
Yandisa amandla e-injini kunye ne-torque : Ii-Turbocharger zonyusa umthamo womoya ongena kwi-cylinder, zenza ukuba injini igalele amafutha amaninzi kwindawo enye, ngaloo ndlela inyusa amandla e-injini kunye ne-torque. Ngokubanzi, i-turbocharger inokunyusa amandla aphezulu e-injini nge-20% ukuya kwi-40%, kunye ne-torque ephezulu ngama-30% ukuya kuma-50%.
Ukunciphisa ukusetyenziswa kwamafutha kunye nokukhutshwa kwe-fuel : I-Turbocharger inciphisa ukusetyenziswa kwamafutha kunye nokukhutshwa kwe-fuel ngokunyusa ukusebenza kakuhle kwe-injini kunye nokuphucula ukusebenza kakuhle kwe-thermal. Ngokukodwa, i-turbocharger inokunciphisa ukusetyenziswa kwe-fuel ye-injini nge-5% ukuya kwi-10%, kunye nokukhutshwa kweegesi ezinobungozi ezifana ne-CO, i-HC kunye ne-NOx nayo iyancitshiswa ngokufanayo.
Uqoqosho lwamafutha oluphuculweyo : Iinjini ezinee-turbocharger zitsha ngcono, zonga i-3% ukuya kwi-5% yamafutha. Ukongeza, ii-turbocharger zandisa iimpawu zokuthelekisa i-injini kunye neempawu zokuphendula okwethutyana kuqoqosho oluphuculweyo lwamafutha.
Ukuphucula ukulungelelaniswa kwe-injini kunye nokuthembeka : I-Turbocharger inokwenza i-injini ibe kwindawo ephakamileyo eyahlukeneyo, amaqondo obushushu kunye neemeko zomthwalo ukugcina ukusebenza okungcono kunye nozinzo, ukunqanda amandla e-injini, ukubetha, ukushisa kunye nezinye iingxaki. Kwangaxeshanye, ii-turbocharger zinokwandisa ubomi be-injini kwaye zinciphise izinga lokungaphumeleli.
Umsebenzi wembuyekezo yeplateau : kwindawo yethafa, ngenxa yomoya omncinci, ukusebenza kweenjini eziqhelekileyo kuya kuchaphazeleka kwaye amandla aya kuncitshiswa. I-turbocharger inokwenza ngempumelelo ilahleko yamandla ebangelwa ngumoya obhityileyo ngokunyusa ingxinano yokuthatha.
