Mazda inoenderera mberi nekuvandudza tekinoroji yeSkyactiv mune ese peturu nedhiziri mabhuroko. Tsvaga ichangoburwa 1.5 Skyactiv D unit iyo inozotanga pane inotevera Mazda 2.
Mushure meiyo 2.2 Skyactiv D block, iko zvino kwave nemukoma mudiki, iyo 1.5 Skyactiv D, iyo ine debut yayo yakanyorwa neramangwana Mazda 2.
Iyi injini nyowani kubva kuMazda ine Skyactiv tekinoroji yatosangana neyakaomesesa EURO 6 zviyero, uye inozviita pasina chero catalysis system. Asi kuti uwane mhedzisiro iyi, Mazda yakatarisana nematambudziko akati wandei anodzikamisa kugona kweDiesel mechanics.
Zvisinei, chigumisiro chakawanikwa, uchishandisa shanduko ye geometry turbocharger uye yakabatanidzwa kutenderera sensor, pamwe chete nemvura-yakatonhorera intercooler, inogutsa zvizere chiJapan brand. Chechipiri, ichavandudza kushanda uye mhinduro ye1.5 Diesel block. Mazda inotenda kuti ichange iine injini yedhiziri yakaderera mukirasi yayo.
Iyo 1.5 Skyactiv D block inozviratidza nekutamiswa kwe1497cc uye 105 horsepower pa4000rpm, iyo torque yakakura ye250Nm inoonekwa sekutanga 1500rpm uye inoramba iripo kusvika padhuze ne2500rpm, zvese neCO₂ emissions ye90g/km chete.
Asi kusvika kune izvi zvakakosha, hazvisi zvose zvakanga zvakanaka uye Mazda akatarisana nematambudziko akawanda ehunyanzvi. Matambudziko ayo maererano nechiratidzo akakundwa, kuburikidza nekushandiswa kwehunyanzvi hwazvino. Asi ngatiendei muzvikamu, nechinangwa chekuburitsa matambudziko ese akakundwa neMazda kugadzira injini ye1.5 Skyactiv D iyi.
Zvaigoneka sei kukunda zvinodiwa zvemamiriro ekunze pasina kudiwa kwekurapwa kwecatalytic?
Diesel blocks anowanzo shanda pamitengo yekumanikidza, yakanyanya kukwirisa kupfuura peturu blocks. Izvi zvinokonzerwa nehutsanana hwekupisa kwedhiziri, iyo inoputika pamatambudziko makuru uye haiputi sepeturu, asi inobata moto.
Nyaya iyi inonyanya kunetsa, sezvo nekuda kweiyo yakakwirira compression ratios, kana piston iri paTDC yayo (yepamusoro yakafa centre), kupisa kunowanzo kuitika kusati kwaitika musanganiswa uye homogeneous musanganiswa pakati pemhepo nemafuta, zvichikonzera kuumbwa kweNOx magasi uye. kusvibisa zvimedu. Kunonoka jekiseni remafuta, uku uchibatsira nekupisa uye kudzvanywa, kunokonzeresa hupfumi hwakanyanya uye nekudaro kushandiswa kwakanyanya.
Mazda, ichiziva nezvematambudziko aya, zvisinei yakafunga kubheja pakudzikisa kudzoreredza reshiyo yeDiesel Skyactiv blocks, ine compression ratios ye14.0: 1 - inooneka yakaderera kukosha kwedhiziri block, sezvo avhareji iri kutenderera 16.0: 1. Uchishandisa mhinduro iyi, uchishandisa mapistoni kubva kumakamuri ekupisa, zvaigoneka kuderedza tembiricha uye kudzvanywa mumasilinda 'PMS, nekudaro optimize musanganiswa.
Nedambudziko iri rakagadziriswa, nyaya yehupfumi hwemafuta yakaramba ichigadziriswa, saka Mazda yakashandura mashiripiti emagetsi. Mune mamwe mazwi, mamepu ejekiseni ane akaomesesa algorithms anokwanisa kuita yakagadziridzwa pre-musanganiswa, mubhuroko rine yakaderera compression mwero. Mukuwedzera kune zvinobatsira pakupisa, kuderedzwa kwehuwandu hwekugadzirisa kwakaita kuti zvikwanisike kuderedza uremu hwevhavha, sezvo iri pasi pekumanikidzika kwemukati mukati, nokudaro kuvandudza kushandiswa uye injini yekukurumidza kupindura.
Mazda yakagadzirisa sei dambudziko rekutonhora kutanga uye kupisa auto ignition ine yakaderera compression reshiyo?
Aya ndiwo aive mamwe matambudziko maviri aive pasi pe block's low compression ratio. Nereshiyo yakaderera yekumanikidza, zvinova zvakanyanya kuoma kuvaka zvakaringana kumanikidza uye tembiricha kuti mafuta atungidze. Kune rimwe divi, kana chivharo chichipisa, iyo yakaderera compression ratio inoita kuti auto-ignition nzvimbo dziome kuECU kubata.
Pakanga pari nekuda kwenyaya idzi iyo Mazda yakasarudza kuisa mu 1.5 Skyactiv D block, ichangoburwa majekiseni ePiezo ane 12-hole nozzles, achibvumira akasiyana majekiseni uye oparesheni mamiriro munguva pfupi kwazvo, achikwanisa kuita akawanda e9 majekiseni pa. cycle , kubvumira kudzora kusanganiswa kwemusanganiswa, kugadzirisa dambudziko rekutanga kutonhora.
Kuwedzera kune matatu ekutanga majekiseni mapatani (pre-jekiseni, jekiseni guru uye post-jekiseni) aya majekiseni ePiezo anogona kuita akati wandei akasiyana mapatani zvinoenderana nemamiriro emuchadenga uye mutoro weinjini.
Auto-ignition yakagadziriswa, nekushandiswa kwekusiyana kwevhavha nguva. Mavharuvhu emhepo anovhura zvishoma panguva yechikamu chekutora, achibvumira magasi emhepo kuti adzokororwe zvakare kukamuri yekupisa, kuwedzera tembiricha, pasina kugadzira nzvimbo dzekumanikidza, nekuti muDiesel inovhara tembiricha inokwira mukamuri yekupisa. kuripa kushandiswa kweyepamusoro compression ratios, iyo inozoburitsa maspikes anonetsa kudzora.
