THE Bosch yakazivisa nezuro shanduko yeinjini dzedhiziri - dzokorora chinyorwa (zvirevo zveMutungamiriri wekambani anofanirwa kunyatsoverengerwa). Shanduko iyo, inoratidzika, yakavakirwa zvachose pamatekinoroji aripo uye, saka, ndiyo mhinduro inogona kuiswa munguva pfupi kuDiesel injini.
Kusimbisa kushanda kwehunyanzvi uhu, nehusiku humwe, Diesel anodzoka mukutamba uye ave zvakare muchinzvimbo chekusangana nezvinoda kuburitsa zvibodzwa - zvimwe zvacho zvinosvika kutanga kwaGunyana. WLTP, wanzwa here?
Asi Bosch - imwe yemakambani anga ari epicenter yekunyomba kwehutsi - yakaita sei chishamiso ichi? Ndizvo zvatichaedza kunzwisisa mumitsetse mishoma inotevera.
Mashandiro Itsva Tekinoroji
Isita yatopera asi zvinoita sekunge Bosch yawana nzira yekumutsiridza injini dzeDiesel. Iyi mhando yeinjini yaive (uye iri…) pasi pemoto nekuda kwekukwira kweNOx emissions yavanoburitsa mumhepo - chinhu chakasiyana neCO2 chinokuvadza zvakanyanya kuhutano hwevanhu.Dambudziko hombe nemainjini edhiziri harina kumbobvira rave CO2, asi kubuda kweNOx kwakagadzirwa panguva yekupisa - zvimedu zvatove zvinodzorwa zvakanaka nechidimbu chefirita. Uye raive chairo dambudziko iri, reNOx emissions, iro Bosch rakabudirira kugadzirisa.
Mhinduro inokurudzirwa neBosch yakavakirwa pane inoshanda epoust gasi kurapwa manejimendi.
Zvinangwa zviri nyore kukunda
Parizvino, iyo NOx emission muganho ndeye 168 milligrams pakiromita. Muna 2020, muganho uyu uchave 120 mg/km. Bosch tekinoroji inoderedza kuburitswa kwezvikamu izvi kusvika ku13 mg/km chete.
Nhau huru nezve iyi nyowani Bosch tekinoroji iri nyore. Iyo inotsamira pane yakawedzera inoshanda manejimendi yeEGR valve (Exhaust Gasi Recirculation). Michael Krüger, mukuru wedhipatimendi rekuvandudza tekinoroji yeinjini dzedhiziri, anotaura naAutocar nezve "inoshanda manejimendi yekupedza gasi tembiricha".
Achitaura kune ichi chinyorwa chechirungu, Krüger akarangarira kukosha kwetembiricha kuti EGR ishande nemazvo: “ iyo EGR inoshanda zvizere chete kana tembiricha yegesi yekubuda inodarika 200°C” . Tembiricha isingawanzosvikwa mumigwagwa yemudhorobha.
"Nehurongwa hwedu tinoedza kudzikisira kurasikirwa kwese kwekushisa, uye saka tinounza EGR padyo sezvinobvira kune injini". Nekuunza EGR padhuze neinjini, inochengetedza tembiricha kunyangwe uchityaira muguta, ichitora mukana wekupisa kunobva injini. Iyo Bosch sisitimu zvakare inobata zvine hungwaru magasi emhepo kuitira kuti magasi anopisa chete apfuure nepakati peEGR.
Izvi zvichaita kuti zvikwanise kuchengetedza magasi akadzokororwa mukamuri yekupisa achipisa zvakakwana, kuitira kuti maNOx particles apiswe, kunyanya mukutyaira kwemaguta, iyo inonyanya kudiwa kwete chete maererano nekushandiswa, asiwo maererano nekuchengetedza kupisa kwejini. .
Inosvika rinhi pamusika?
Sezvo mhinduro iyi yakavakirwa paBosch Diesel tekinoroji yakatoshandiswa mukugadzirwa kwemotokari, pasina kuda chimwe chekuwedzera chikamu chehardware, kambani inotenda kuti iyi system inofanirwa kuona chiedza chezuva munguva pfupi.
