Sensa ya throttle ya filimu ya kaboni ikulandira luso lamakono, magetsi a magalimoto amapangitsa kuti pakhale kufunikira kolondola kwambiri

2025-03-15

Poganizira za kusintha mwachangu magalimoto atsopano amphamvu komanso mpikisano wamsika wa magalimoto omwe alipo kale amafuta, makampani opanga makina oletsa kupopera mpweya pogwiritsa ntchito filimu ya carbon film akuyang'ana mwayi wosiyanasiyana wokulira kudzera mu luso lamakono komanso kusintha njira zamsika.

Chojambulira cha throttle cha filimu ya kaboni chikulandira luso lamakono

Mu 2024, msika wapadziko lonse wa ma resistor a carbon film resistor ukuyembekezeka kufika madola 880 miliyoni aku US, pomwe throttle sensor field ikuthandiza gawo loposa 1/4 la msika. Ngakhale kuti akukumana ndi mavuto aukadaulo ochokera ku ma resistor a film ndi metal film, makhalidwe awo otsika mtengo komanso odalirika kwambiri akadali olimba pakati pa magalimoto otsika mtengo komanso mafakitale.

Mu Okutobala 2023, Strategy Analytics, kampani yofufuza msika wa masensa a magalimoto padziko lonse lapansi, idatulutsa lipoti lonena kuti kutumiza pachaka kwa masensa a carbon film throttle sensors (CF-TPS) kudapitilira mayunitsi 120 miliyoni koyamba, kuwonjezeka kwa chaka ndi chaka kwa 9.8%. Ndi kulimbitsa malamulo otulutsa mpweya m'magalimoto amafuta komanso kuchuluka kwa mitundu yosakanikirana, msika uwu ukuyembekezeka kufika pamlingo wa madola 3.4 biliyoni aku US pofika chaka cha 2028, ndi kuchuluka kwa kukula kwa 6.5%.

Kupambana kwa ukadaulo: Njira yopangira nanocoating imawonjezera kulimba

Posachedwapa, Alps Alpine ku Japan yatulutsa CF-TPS ya m'badwo wachinayi, yomwe imagwiritsa ntchito ukadaulo wa filimu ya nanocarbon yopopera ndi plasma kuti ikonze kulondola kwa mzere kufika pa ± 0.3 ° ndikuwonjezera moyo wa ntchito mpaka 15 miliyoni, kuwonjezeka kwa 40% poyerekeza ndi mtundu wakale wa chinthucho. Chogulitsachi chadutsa satifiketi yachitetezo cha ISO 26262 ndipo chayikidwa mu dongosolo laposachedwa la hybrid la Toyota. Chophimba cha nano chimalola sensa kusunga kukhazikika kwa chizindikiro pansi pa mikhalidwe yogwirira ntchito kuyambira -40 ℃ mpaka 140 ℃, kuthetsa vuto la hysteresis m'malo otentha kwambiri, "adatero Hiroshi Yamada, director wa R&D wa kampaniyo.

Chojambulira cha throttle cha filimu ya kaboni chalandira luso lamakono1

Kufunika kwa msika komwe kulipo pakali pano kukuwonetsa kusiyana: magalimoto achikhalidwe amafuta ndi 63%, omwe amagwiritsidwa ntchito kwambiri pokonza chiŵerengero cha mpweya ndi mafuta a injini; Kufunika kwa magalimoto osakanikirana kwawonjezeka ndi 27% chaka ndi chaka, kukhala chiwongola dzanja chachikulu. CF-TPS yanzeru yopangidwa ndi Bosch imatha kusinthana bwino pakati pa mitundu yamafuta/magetsi, ndi nthawi yoyankha yosinthika yochepetsedwa kufika pa 15ms, ndipo yapambana maoda kuchokera ku makampani monga Geely ndi Great Wall Motors.

Ndikofunika kudziwa kuti magalimoto a haidrojeni akhala njira yatsopano yogwiritsira ntchito. CF-TPS yolimba ya haidrojeni yolimbana ndi dzimbiri yopangidwa ndi Sensata Technology imagwiritsa ntchito ma contacts a platinum alloy ndi kapangidwe ka multi-layer sealing, ndipo yapambana mayeso a hydrogen environment a 70MPa. Ikukonzekera kufananizidwa ndi Hyundai Nexo facelift model mu 2024.

Opanga aku China amadutsa zopinga za patent zakunja

Jiangsu Aoliwei Sensing yalengeza kuti yamaliza ntchito yomanga mzere woyamba wopangidwa ndi CF-TPS wopangidwa ndi anthu wamba, pogwiritsa ntchito ukadaulo wa AI dynamic calibration kuti ipititse patsogolo kulondola kwa kayendetsedwe ka zinthu kufika pa 98.5%. "Njira yake yapadera yoika filimu ya carbon gradient" imapewa zoletsa za patent zakunja ndipo imapeza phindu loposa 92%. Mtundu wamagetsi ambiri (4.5V-24V) womwe tidapanga walowa mu unyolo wa BYD. CTO wa kampaniyo Zhou Ming wavumbulutsa. Deta ikuwonetsa kuti gawo la msika wa CF-TPS yopangidwa ndi anthu wamba pamsika wogulitsa pambuyo pogulitsa lawonjezeka kuchoka pa 19% mu 2020 kufika pa 37% mu 2023.

Zochitika Zamtsogolo: Kuphatikizana ndi Kuzindikira Mwanzeru

Akatswiri amakampani akunena kuti pokhazikitsa muyezo wa EU Euro 7 emission, masensa anzeru okhala ndi mphamvu zodziyeretsa okha adzakhala otchuka. Yankho lophatikizidwa lomwe lalengezedwa posachedwapa ndi Continental Group limaphatikiza CF-TPS ndi masensa okhala ndi pedal position ndipo limakwaniritsa kuzindikira cholakwika cha millisecond kudzera mu CAN FD bus. Kuphatikiza apo, kuyambitsa kwa Silicon Carbide Ukadaulo wa substrate ukuyembekezeka kukweza malire apamwamba a kutentha kwa ntchito kufika pa 200 ℃ pofika chaka cha 2025.
