I-sensor ye-throttle yefilimu yekhabhoni yamkela ubuchule bobuchwephesha, ukufakelwa kombane kwiimoto kuqhuba imfuno echanekileyo kakhulu

2025-03-15

Ngokuchasene nokutshintshwa ngokukhawuleza kwezithuthi ezintsha zamandla kunye nokhuphiswano lwemarike lwezithuthi zamafutha ezikhoyo, imboni ye-resistor ye-carbon film throttle sensor ihlola amathuba okukhula ahlukeneyo ngokusebenzisa ubuchule bobuchwepheshe kunye nohlengahlengiso lwesicwangciso semarike.

Isixhobo sokuvavanya i-throttle sefilimu yekhabhoni samkela ubuchule bobuchwepheshe

Ngowama-2024, ubungakanani bemarike yehlabathi yee-resistors zefilimu yekhabhoni kulindeleke ukuba bufikelele kwi-880 yezigidi zeedola zaseMelika, kunye nentsimi ye-throttle sensor enegalelo elingaphezulu kwe-1/4 yesabelo semarike. Nangona bejamelene noxinzelelo lobuchwephesha oluvela kwii-resistors zefilimu ezinkulu kunye neefilimu zesinyithi, iimpawu zazo ezingabizi kakhulu nezithembekileyo zisasebenza kakuhle kwiimodeli zezithuthi eziphakathi ukuya kweziphantsi kunye neemeko zoshishino.

Ngo-Okthobha ka-2023, iStrategy Analytics, inkampani yophando lwemarike ye-sensor yeemoto yehlabathi, ikhuphe ingxelo ethi ukuthunyelwa rhoqo ngonyaka kwe-carbon film throttle sensors (CF-TPS) kudlule kwiiyunithi ezili-120 lezigidi okokuqala, ukunyuka konyaka nge-9.8%. Ngokuqiniswa kwemithetho yokukhupha umbane kwizithuthi zepetroli kunye nokwanda kwenani leemodeli ze-hybrid, le marike incinci kulindeleke ukuba ifikelele kwisikali seedola zaseMelika eziziibhiliyoni ezi-3.4 ngo-2028, kunye nezinga lokukhula elidibeneyo eliyi-6.5%.

Impumelelo yetekhnoloji: Inkqubo yokugquma i-nano yomeleza ukuqina

I-Alps Alpine eJapan isandula ukukhupha isizukulwana sesine i-CF-TPS, esebenzisa ubuchwepheshe befilimu ye-nano carbon etshizwa nge-plasma ukuphucula ukuchaneka komgca ukuya kwi-± 0.3 ° kwaye yandise umjikelo wobomi ukuya kwimisebenzi eyi-15 yezigidi, ukunyuka kwama-40% xa kuthelekiswa nemveliso yesizukulwana sangaphambili. Le mveliso iphumelele isiqinisekiso sokhuseleko olusebenzayo se-ISO 26262 kwaye ifakwe kwinkqubo yamva nje ye-hybrid yeToyota. I-nano coating ivumela i-sensor ukuba igcine uzinzo lwesignali phantsi kweemeko zokusebenza ukusuka kwi--40 ℃ ukuya kwi-140 ℃, isombulula ingxaki ye-hysteresis kwiindawo ezinobushushu obuphantsi, "utshilo uHiroshi Yamada, umlawuli we-R&D wenkampani.

Imfuno yemarike yangoku ibonisa indlela yokwahluka: izithuthi zepetroli zemveli zimalunga nama-63%, ezisetyenziselwa kakhulu ukuphucula umlinganiselo womoya-mafutha enjini; Imfuno yezithuthi ezixutyiweyo inyuke ngama-27% unyaka nonyaka, iba yingongoma ephambili yokukhula. I-CF-TPS ekrelekrele yeendlela ezimbini eqaliswe yiBosch inokufikelela ekutshintsheni okungenamthungo phakathi kweendlela zepetroli/zombane, kunye nexesha lokuphendula eliguqukayo elincitshisiweyo ukuya kwi-15ms, kwaye iphumelele iiodolo ezivela kwiimpawu ezifana neGeely kunye neGreat Wall Motors.

Kubalulekile ukuqaphela ukuba izithuthi ze-hydrogen fuel cell ziye zaba yindlela entsha yokusetyenziswa. I-CF-TPS ye-hydrogen enoxinzelelo oluphezulu enganyangekiyo nokugqwala eyenziwe yiSensata Technology isebenzisa izixhobo zeplatinum alloy contacts kunye nesakhiwo sokutywina esineengqimba ezininzi, kwaye iphumelele ngempumelelo uvavanyo lwe-hydrogen environment lwe-70MPa. Kucetywayo ukuba ihambelane nemodeli ye-Hyundai Nexo facelift ngo-2024.

Abavelisi baseTshayina baphula imiqobo yelungelo elilodwa lomenzi wepatent phesheya

I-Jiangsu Aoliwei Sensing ibhengeze ukugqitywa kokwakhiwa komgca wokuqala wemveliso ye-CF-TPS ozenzekelayo oveliswa ngaphakathi, kusetyenziswa iteknoloji yokulinganisa enamandla ye-AI ukuphucula ukuchaneka kokulawula ukuhambelana kwemveliso ukuya kwi-98.5%. "Inkqubo yayo ekhethekileyo yokufaka ifilimu ye-gradient carbon" ithintela imiqathango yelungelo lomenzi phesheya kwaye ifikelela kwizinga lemveliso elingaphezulu kwe-92%. Inguqulelo ye-voltage ebanzi (4.5V-24V) esiyiphuhlisileyo ingenile kuluhlu lobonelelo lwe-BYD. I-CTO yenkampani uZhou Ming ityhile. Idatha ibonisa ukuba isabelo semarike se-CF-TPS eveliswa ngaphakathi kwimarike emva kokuthengisa sinyuke ukusuka kwi-19% ngo-2020 ukuya kwi-37% ngo-2023.

Iindlela Zekamva: Ukudibanisa kunye nokuxilongwa okukrelekrele

Abahlalutyi bemizi-mveliso bathi ngokuphunyezwa komgangatho wokukhutshwa kwe-EU Euro 7, izinzwa ezikrelekrele ezinezakhono zokuzicoca ziya kuba yinto eqhelekileyo. Isisombululo esidibeneyo esisandula ukubhengezwa yiContinental Group sidibanisa i-CF-TPS nezinzwa zesikhundla sepedali kwaye sifezekisa ukuxilongwa kwempazamo kwinqanaba le-millisecond ngebhasi ye-CAN FD. Ukongeza, ukwaziswa kwe iSilicon Carbide Itekhnoloji ye-substrate kulindeleke ukuba inyuse umda ophezulu wobushushu bokusebenza uye kwi-200 ℃ ngo-2025.
