Injini Nissan SR20De

Injini yeNissan SR20De inomiririra mhuri huru yemagetsi epetroli yekambani yeJapan, yakabatanidzwa ne SR index. Huwandu hweinjini idzi hwakabva pa1,6 kusvika ku2 malita.

Chinhu chikuru chehunyanzvi cheiyi mota ndeye aluminium cylinder musoro uye simbi, kutaura zvazviri, cylinder block. Idzi injini dzemukati dzinopisa (ICE) dzakagadzirwa kubva 1989 kusvika 2007.

Nhamba dziri mukumakwa kwesimba remagetsi dzinoratidza saizi yeinjini. Kureva, kana muchina injini iri SR18Di, vhoriyamu yayo 1,8 litres. Saizvozvo, kune iyo SR20De injini, iyo injini yekusimuka yakaenzana nemarita maviri.

Iyo SR yakatevedzana injini uye, kunyanya, iwo maviri-lita injini dzeiyi nhevedzano, akaiswa pane yakakura kwazvo runyorwa rwemotokari dzinotakura vanhu dzakagadzirwa naNissan mumakore ekuma90 "zero".

Nhoroondo yeNissan SR20De injini

Pakati pemasimba ese emagetsi eiyo SR akateedzana, SR20De ndiyo inonyanya kuzivikanwa, uye mumwe angatoti yakakurumbira munyika yedu. Idzi mota dzakaiswa pachizvarwa chechisere cheNissan Bluebird modhi, iyo yainyatso tengeswa kunze kwenyika, kutanga kuUSSR, uyezve kuRussia, nevatengesi vegrey kana kungoita distillers.

Pamberi pekuuya kweinjini idzi, muchikamu che 2-litre magetsi emagetsi, maJapan akabudisa CA20. Injini iyi yairema chaizvo, maererano nehukuru, sezvo bhuroka rayo nemusoro zvaive nesimbi yakakandwa. Muna 1989, akareruka, aruminiyamu SR20 akaiswa paBluebirds, ayo aive nemhedzisiro inobatsira pane ese ari maviri ane simba maitiro emotokari uye kugona kwavo. Zvakare, nekuda kwehupfumi uye kuita kwepamusoro, injini dzinopisa dzemukati idzi dzaive nejekiseni remapoinzi akawanda uye mavharuvhu mana pacylinder.

Kubva pakutanga kwekugadzirwa, chivharo chevharuvhu chitsvuku chakaiswa pamagetsi aya. Kune izvi, mota dzakagamuchira zita SR20DE Red kumusoro High port. Aya maICE akamira pamutsetse wegungano kusvika 1994, paakatsiviwa neSR20DE Black top Low port injini.

Kubva kune yakatangira, mukuwedzera kune yevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhu,ichi simba yuniti yaisiyaniswa neatsva inlet chiteshi che cylinder head (cylinder head). Iyo itsva 240/240 camshaft (yakatangira yaive ne248/240 camshaft) uye itsva exhaust system ine 38mm pombi (iyo SR20DE Red top High port yaive ne45mm exhaust pombi). Injini iyi yakamira pamutsetse wegungano kusvikira muna 2000, kunyange zvazvo isiri mumamiriro asina kuchinjwa, muna 1995 pamotokari pakabuda 238/240 camshaft itsva.

Muna 2000, iyo SR20DE Nhema yepamusoro Yakaderera port yakatsiviwa neyakakwidziridzwa SR20DE roller rocker ICE. Izvo zvakakosha zveiyi simba unit yaive roller rockers uye itsva valve return springs. Dzimwe shanduko dzakakodzera kucherechedzwa mapistoni akagadziridzwa zvishoma, crankshaft yakareruka uye yakapfupikiswa yakawanda yakawanda. Iyi shanduko yaive mukugadzirwa kusvika 2002. Mushure meizvozvo, iyo SR20DE yemhepo injini dzakamiswa. Nekudaro, turbocharged shanduro dzeinjini iyi dzakaramba dzichigadzirwa uye nhoroondo yavo ichakurukurwa pazasi.

Nhoroondo ye turbocharged SR20DET injini

Inenge panguva imwe chete neinjini yakasikwa, vhezheni yayo ye turbocharged yakaonekwa, ine zita rekuti SR20DET. Yekutanga vhezheni, nekuenzanisa neinjini yakasarudzika, yainzi SR20DET Red top. Iyi ICE yakagadzirwa, senge shanduro yayo yemhepo, kusvika 1994.

Iyi mota yaive neGarrett T25G turbine, iyo yakaburitsa kudzvanywa kwe0,5 bar. Uku kumanikidza kwakaita kuti zvikwanise kugadzira simba re205 hp. pa6000 rpm. Iyo torque yeinjini yekupisa yemukati yaive 274 Nm pa4000 rpm.

Kuti uchengetedze hupenyu hweinjini, chiyero chekumanikidza chakaderedzwa kusvika 8,5 uye tsvimbo dzekubatanidza dzakasimbiswa.

Zvichienderana nechikamu ichi chemagetsi, muna 1990 imwe shanduro yakatonyanya kusimba yakaonekwa, ine simba re230 hp. pa6400 rpm uye torque ye280 Nm pa4800 rpm. Yakasiyana neyakatangira neimwe Garrett T28 turbine, iyo yakaburitsa kudzvanywa kwe0,72 bar. Zvakare, mukuwedzera kune izvi, shanduko dzinotevera dzakaitwa kune iyo simba unit. Akagamuchira camshaft yakasiyana 248/248, mamwe majekiseni emafuta ane simba re 440 cm³ / min, mamwe mabhomba emafuta, crankshaft, tsvimbo dzekubatanidza uye cylinder head bolts zvakasimbiswa.

Kufanana neshanduro yemhepo, chizvarwa chinotevera chechikamu chemagetsi ichi chakaonekwa muna 1994. Akagamuchira zita rokuti Nissan SR20DET Black top. Pamusoro pevhavha yevhavha nhema, iyo yakava chiratidzo cheinjini iyi, yaivewo nelambda nyowani uye pistons. Pamusoro pezvo, nzira dzekupinza nekubuda nadzo dzakachinjwa, uye dhizaini yekombuta iri pabhodhi yakachinjwawo.

Imwe yakasiyana, ine simba zvikuru yeinjini iyi yakasunungurwa yeNissan S14 Silvia yemitambo yemotokari. Motokari iyi yakanga ine injini ye220 hp. pa6000 rpm uye torque ye275 Nm pa4800 rpm.

Nekudaro, iyo yakanyanyisa vhezheni yemagetsi unit yakaiswa pane inotevera, yechinomwe chizvarwa Sylvia, iyo yakabereka iyo S15 index. Injini yemota iyi yaive neGarrett T28BB turbo ine intercooler yakagadzira kudzvanywa kwe0,8 bar. Mukuwedzera, yakanga yakagadzirirwa mononozzle ine simba re 480 cm³ / min. Mushure memazuva ano, injini yekupisa mukati yakagadzira simba re 250 hp. pa6400 rpm uye ine torque ye300 Nm pa4800 rpm.

Dzimwe shanduro mbiri dzeSR20DET dzaive paNissan Avenir station wagon isingazivikanwe. Pamuchina uyu, maviri emagetsi, maviri-lita mayuniti ane simba re 205 uye 230 hp akagadzirwa kamwechete.Idzi mota dzakanzi Nissan SR20DET Silver top.Chikuru chinosiyanisa mayuniti aya chaive chivharo chegivhavha.

Zvisinei, shanduro yakasimba kwazvo yejini yeNissan SR20 yakaiswa, yatova muzana remakore rechi21, pane inozivikanwa yeNissan X-Trail GT crossover. Ichokwadi, iyi shanduro ye crossover haina kutengeswa zviri pamutemo muRussia.

Saka, iyi vhezheni yakanzi SR20VET uye yakaiswa pachizvarwa chekutanga X-Trails yemusika wekuJapan. Iyi vhezheni, seyekutanga chizvarwa checrossover, yakabudiswa kubva muna 2001 kusvika muna 2007. Iyi ICE yakagadzira simba re280 hp. pa6400 rpm uye yaive torque ye315 Nm pa3200 rpm. Pakati pemagadzirirwo emhando iyi yemagetsi, zvakakosha kucherechedza iyo 212/248 camshafts uye Garrett T28 turbine, ine inosimudzira kudzvanywa kwe0,6 bar.

Mukupedzisa nyaya pamusoro penhoroondo yejini yeNissan SR20De, zvinofanira kutaurwa kuti ndiyo inonyanya kuzivikanwa pakati pese SR series.

Motor kuvimbika

Kusiyana, zvinofanira kutaurwa pamusoro pechigadzirwa chemotokari iyi, sezvo mazhinji emagetsi emagetsi panguva iyoyo, akabudiswa munyika yezuva rinobuda, anenge asingagumi. Boka ravo repiston, nyore, rinoenda hafu yemiriyoni makiromita kana kupfuura. Mune mamwe mazwi, idzi injini dzinopisa dzomukati dzine chigadziro chakareba kudarika chitubu chemitumbi yemotokari iyo yavakaiswa.

Pamatambudziko akakomba pane aya mayunitsi emagetsi, kutadza kusati kwasvika kweasina basa anomhanyisa controller uye mass air flow flow sensor inocherechedzwa. Matambudziko aya anomuka zvakanyanya nekuda kwekuderera kwemafuta munyika yedu.

Zvakanaka, mukuwedzera kune yakasarudzika kuvimbika kweboka repiston, mukana wemamotor aya kusavapo kwebhandi mune yenguva meshini drive. Idzi mota dzine camshaft cheni drive, uye cheni, zvakare, ine sosi yemakiromita 250 - 300.

Rudzii rwemafuta kudira

Kufanana nemotor dzese dzesangano, Nissan SR20 haina kuzvikudza kumafuta anoshandiswa. Aya anotevera API mafuta anogona kushandiswa muinjini iyi:

• 5W-20
• 5W-30
• 5W-40
• 5W-50
• 10W-30
• 10W-40
• 10W-50
• 10W-60
• 15W-40
• 15W-50
• 20W-20

Kana ari mugadziri wemafuta, kambani yeJapan inokurudzira kushandisa mafuta avo. Uye zvine musoro kuashandisa. Icho chokwadi ndechekuti mafuta eNissan haawanikwe kutengeswa mahara, anowanikwa chete kune vatengesi vepamutemo vekambani uye kushandiswa kwavo kunovimbisa kuti iwe unozadza mafuta chaiwo epakutanga, iyo yekumaka iyo pane canister inoenderana nezviri mukati.

Zvakanaka, kana iri ruzivo rwuri pagaba, zvino:

• Simba Save X ndiro zita remafuta;
• 5W-30 - kupatsanurwa kwayo maererano API;
• SN - nhamba yekutanga mukumaka iyi inoratidza kuti mafuta aya ndeapi injini;

1. S - inoratidza kuti mafuta e peturu injini;
2. C - nokuti dizeli;
3. N - inoratidza nguva yekuvandudzwa kwemafuta. Kuwedzera kwetsamba kubva pabhii rekutanga "A", iyo inonyanya kukosha. Somuenzaniso, mafuta "N" akaonekwa gare gare pane mafuta ane tsamba "M".
