Musiyano uripo pakati peiyo yepamusoro-simba EA888 Gen3 uye yakaderera-simba EA888 Gen3B (mazera matatu nehafu) injini yakakura kwazvo. Nekuda kwekushandiswa kweakasiyana zvachose masisitimu ekupisa uye zvinangwa zvekuita, kune misiyano yakawanda muhardware, kunyanya misiyano inotevera:
1. Akasiyana masisitimu ekupisa:
Iyo yepamusoro-simba EA888 Gen3 inotora iyo yechinyakare Otto kutenderera, nepo yakaderera-simba EA888 Gen3B inoshandisa iyo Miller cycle kuderedza kushandiswa kwemafuta, saka mapistoni, silinda musoro conmbustion chambers, cylinder head air ports, majekiseni, compression ratios, nezvimwe zviviri zvakasiyana.
Chii chinonzi Miller cycle?
Iyo yakaderera-simba EA888 Gen3B inoshandisa kutanga kuvhara kwevharuvhu yekutora kuti iwane kutsva nereshiyo yekuwedzera yakakura kupfuura reshiyo yekumanikidza, nekudaro ichivandudza kupisa kwemafuta. Kazhinji kutaura, kutenderera kweMiller kunounza kurasikirwa kukuru kwekuita. Rutivi rwekutora rweEA888 Gen3B injini yakagadzirwa iine AVS variable valve lift mechanism, inoshandisa tekinoroji yekusimudza tekinoroji kuenzanisa chikamu chekurasikirwa kwekuita kwakakonzerwa neMiller kutenderera. Naizvozvo, chinangwa cheVolkswagen mukugadzira iyo yakaderera-simba EA888 Gen3B ndeyekuzadzisa mwero wekushandisa mafuta we1.4T uye chiyero chekushanda che1.8T.
Nheyo yeMiller kutenderera
Nekuvhara vharuvhu kare, chiyero chekuwedzera chinogona kunge chakakura kupfuura chiyero chekumanikidza, uye kurasikirwa kwekupomba kunogona kuderedzwa.
Piston EA888 1.8T
Misiyano pakati peGEN3 Otto cycle uye GEN3B Miller cycle
(1) Misiyano muvharuvhu uye dhizaini yepiston: GEN3B's dhayamita yevharuvhu yekupinda idiki uye pamusoro pepiston yakakwira, inogona kuwana kumanikidza reshiyo ye11.7 (GEN)
3's compression ratio ndeye 9.8).
(2) Misiyano muchiteshi chemhepo uye cam profile dhizaini: GEN3B yakagadzirirwa nehombe tumble yekupinda chiteshi uye yakaderera-inosimudza cam profile kuti iwane iyo Miller kutenderera.
2. Kusiyana kwevhavhavha inosimudza AVS design
Iyo inoshanduka vharafu inosimudza sisitimu AVS yeiyo yepamusoro-simba EA888 Gen3 iri padivi rekubuda. Iyi ndiyo yechinyakare AVS dhizaini yeEA888, zvave zvakadaro kubva kuchizvarwa chechipiri. Chinangwa chayo chikuru ndechekuvandudza yakaderera-kumhanya torque uye supercharger ine simba mhinduro uye kuderedza turbo lag.
The variable valve lift system AVS yeyakaderera-simba EA888 Gen3B iri padivi rekutora, kunyanya kugadzirisa chikamu chekurasikirwa kwemagetsi kunokonzerwa neMiller cycle (asi haisati yasvika padanho rekuita resimba repamusoro).
3. Kusiyana kwemafuta-gasi separator design
Oiri-gasi separator yeyepamusoro-simba vhezheni yeEA888 Gen3 yakabatana zvakananga kubva kune crude oil separator mhango yecylinder block kune yakanaka mafuta-gasi separator pamusoro wecylinder.
Kuti uwane kupatsanurwa kuri nani kweoiri-gasi uye kuwedzera kuderedza kushandiswa kwemafuta, iyo yakaderera-simba vhezheni yeEA888 Gen3b inoshandisa gomba reyekupinza-parutivi chiyero shaft pane cylinder block seyakanyanya kupatsanurwa kweoiri-gasi, uye inowana kupatsanurwa kwekutanga kuburikidza nekumhanya-kumhanya kwebhari shaft (iyo yekumhanyisa inopetwa kaviri iyo ye crankshaft yemafuta), uye ipapo inoenda kune iyo crankshaft separator, uye ipapo inoenda kune iyo crankshaft mafuta. Iyi dhizaini ichave nekushomeka kwemafuta.
4. Kusiyana mukati crankshaft dhayamita
Iyo yakaderera-simba GEN3B injini inosarudza diki crankshaft main shaft dhayamita kuderedza kukweshera uye kuderedza kushandiswa kwemafuta.
5. Kusiyana mukushandiswa kwemafuta
Zvinogona kuoneka kuti iyo yakaderera-simba vhezheni yeGEN3B yakanyatso kugadzirirwa kuwana yakaderera kushandiswa kwemafuta uye kugona kwakanyanya. Saka, kushanda kweiyo yakaderera-simba shanduro yeGEN3B inogona kuvandudzwa ne8% kana ichienzaniswa neiyo yepamusoro-simba shanduro yeGEN3.
Kushandiswa kwemafuta einjini mumamiriro ese ekushanda kwakaderedzwa zvakanyanya:
Kushandiswa kwemafuta eGEN3B zvakare kwakadzikira pane kuya kweGEN3:
Pfupisa
Pane musiyano mukuru pakati pepamusoro uye pasi simba rechitatu-chizvarwa EA888 injini. Iro simba repamusoro rakarerekera kune mashandiro, nepo simba rakaderera rakagadzirirwa kuderera kwemafuta.
