Kana vakaperekedza Reason Automobile, hazvisi zvitsva kana tichiti injini dzedhiziri dziri kutyirwa kutsakatika. Dieselgate yakaitika makore maviri apfuura, asi isu tichiri kuona zvakazoitika pachiitiko ichi. Kushandiswa kweDiesel kuderedza kubudiswa kweCO2 kuri panjodzi, sezvazviri chaizvo.
Iyo "yekare" dambudziko / mhinduro
Magetsi haisi mhinduro yenguva pfupi, saka vavaki vanozove ne "yekare" mukati memoto injini seyakanyanya tekinoroji sosi yekusangana nezvinotarirwa zvekudzikisa emission. Takatotaura zvimwe zvingangoitika pano, ingave mumunda weinotevera-injini yekupisa - Mazda's SKYACTIV-X, Nissan's VC-T kana Koenigsegg's Freevalve -, kana kunyangwe mumunda wemafuta akadai seBosch's eFuel.Pakati pekusaziva kwakawanda, pane chokwadi chimwe: kufambira mberi uku mumajini anopisa. ichaperekedzwa nekuwedzera kwemazinga ehybridization. Apa ndipo panopinda Delphi, hofori iyo inopa indasitiri yemotokari nemhinduro mumunda wezvikamu.
48V + Cylinder deactivation = 19% kuderedza kushandiswa
Mhinduro yeDelphi inosanganisira kujoinha zvigadziriso zviviri zviri kubuda zvetekinoroji: semi-hybrids (mild hybrids) ine 48V magetsi masisitimu uye mhando nyowani yehumburumbira deactivation iyo kambani inodana Dynamic Skip Fire.
48V masisitimu ari kutanga kurova pamusika - iyo itsva Audi A8 inoisanganisa mumainjini ese, semuenzaniso (asi yekutanga yaive Audi SQ7). Ivo vanobvumira "simba" kutanga-kumisa masisitimu, iwo akasiyana zvakanyanya peripherals - pombi yemvura, radiator, air conditioning -, mabhureki, chidhiraivho uye kunyange turbos, kuwedzera simba remagetsi einjini. Nekudaro, ivo havatsive iyo 12V yemagetsi sisitimu yemotokari dzazvino. Aya acharamba achibata nemwenje uye infotainment masisitimu.
Inoshanda sei?
Iyo sisitimu zvakare inotsiva yekutanga uye alternator neinjini-jenereta - iyo yakabatana kune crankshaft nebhandi - uye ine lithium-ion bhatiri kuchengetedza simba. Iyo haibvumiri kufambiswa kwemagetsi, asi inosunungura injini inopisa mukati kubva pakusimbisa huwandu hwemagetsi emagetsi, sezvo inobatsira mukutanga kana kunyange "kupwanya" accelerator, ichipa "boost" yenguva pfupi torque.
Sekureva kweDelphi, semi-hybrids inobvumira 70% yemafuta ekuchengetedza mafuta emhando yakasanganiswa pachikamu che30% chemutengo. Nemitengo yemakwikwi, padanho reDiesel, semi-hybrids inofanirwa kuve yakanyanyozivikanwa tekinoroji mhinduro sezvatinopinda mumakore gumi anotevera.
Kudzima cylinder paisingadiwi
Zvinorehwa neDelphi ndezvekubatanidza 48V system neimwe tekinoroji yakatounzwa navo - Dynamic Skip Fire. Seri kwezita iri panogara rudzi rutsva rwe silinda deactivation tekinoroji. Chaizvoizvo pachinzvimbo chekudzima bhangi rese remasilinda - seV8 - iyi sisitimu inosarudza panhunzi kuti kana kuti kwete silinda yakaitwa.Kana iyo system ikaona kuti haina kukodzera kupinza mafuta muhumburumbira, ichiongorora imwe seti yeparameter, inoita kuti mavharuvhu ekupinda uye ekupera arambe akavharwa. Sezvo sisitimu inoshanda nekudzora spark plug, injini dzepeturu chete dzinoenderana nemhinduro iyi.
Kunyangwe mabhenefiti eiyi tekinoroji achinyanya kuoneka muinjini hombe uye nenhamba yakawanda yemasilinda, iyo prototype inoratidzwa (mumifananidzo) inoshandisa ina-cylinder turbo injini.
Sekureva kwaDelphi, musanganiswa weaya matekinoroji maviri anogona kuwedzera kuchengetwa kwemafuta einjini yepeturu kusvika 19% mukutyaira mudhorobha uye 14% mukutyaira mumigwagwa, maererano neinoda zvakanyanya North America kutenderera, inotsanangurwa neEPA. Hunhu hwakadai hunoiisa parutivi neinjini yedhiziri iripo.
Tekinoroji yakagadzirira, asi haifanirwe kusvika 2020 isati yasvika
Matekinoroji ese ari maviri anogona kushandiswa akaparadzana, asi anozadzisa mumwe nemumwe nekuwedzera thruster kunyatsoshanda pane zvese zvakaderera uye zvakakwirira mitoro. Sekureva kwaDelphi, inogona kunge iri mhinduro, kunyanya muEurope, kutarisana nekutsamira paDiesel yevamwe vanogadzira.
Dave Sullivan, muongorori weAutoPacificIyo 48V semi-hybrid system haina mabhenefiti akawanda paEPA's test cycle, asi musanganiswa wetekinoroji mbiri idzi methadone Europe inoda kuputsa kupindwa muropa neDiesel.
Diesel achiri kuita ruzhinji rwekutengesa kune vakawanda vanogadzira muEurope, kunyanya iwo ekutanga, kunyangwe kutengesa kuri kudzikira. Kukombwa kweDiesel kwatanga tichiona kuchamanikidza vagadziri kuti vatore iyi kana yakafanana mhinduro kuitira kuti vasangokwanisa kuzadzisa zvinangwa zvekuburitsa, asiwo kuchengetedza kuita kwekutengesa. China zvakare - iyo iri kuitawo hukasha hwekudzikisa zvibodzwa - inogona kuve chinhu chakakosha mukutorwa kwehunyanzvi uhu.
Maererano neDelphi, ichitaura data kubva kuHS Markit, magetsi acharamba zvishoma nezvishoma, nekufamba kwenguva, anotora nzvimbo yezvinjini zvinopisa, saka haazozvitsivi pakarepo. Naizvozvo, mamwe marudzi emhinduro anodiwa.
Asi…
Kunyangwe mari yekushandisa ichienzaniswa - kana isiri pasi - kune yeDiesel yazvino, pane poindi inogona kureba vanovaka kubva pakushandisa panguva imwe chete yetekinoroji mbiri. Iyo Dynamic Skip Fire inoreva imwezve mutengo we € 350 pamotokari, asi haitauri mutengo ungangoita wekugadzirisazve misoro yeinjini kuti ibatanidze sisitimu. Kana iyi system ichizobatanidzwa muinjini iripo, shanduko itsva yemafuta inogona kudiwa pamwe nenzvimbo yekuwedzera solenoid yecylinder yega yega.
Nekudaro, kana vakagamuchira mhinduro iyi, sekureva kwaMary Gustanski, Mutevedzeri weMutungamiriri weDelphi weUinjiniya, kuburitswa kweCO2 kuchafanana nekweDiesel, asi nekuita kwepamusoro.
