Common Sitima Yapamtunda - ndichiyani? Mfundo ntchito

M'zaka zaposachedwapa, anthu ambiri ziziyenda amakonda kugwiritsa ntchito magalimoto dizilo. Poyamba, Motors awa amene anaika yekha pa galimoto malonda. Komabe, iwo tsopano ankagwiritsa ntchito magalimoto m'sitimayo, makamaka ku Europe. Ndithudi aliyense wa ife anamva za dongosolo chotero, ngati Common njanji. Kodi ndi motani ntchito, tikambirana chiyani m'nkhani ino.

mbali

"Common Ryle" - dongosolo mafuta jekeseni kuti injini dizilo. Mfundo zake za ntchito zachokera kundipatsako kwa mafuta kwa injectors wa njanji kuthamanga wamba. Kachitidwe anayamba kupanga ndi akatswiri German wa kampani "Bosch". Common Sitima Yapamtunda Bosch ambiri ntchito mu galimoto monga "Volvo", "Mercedes", BMW ndi ena.

Kodi wapadera?

Waukulu zimasiyanitsa mbali ya dongosolo - mphamvu kupereka mphamvu anakhumba ndi mafuta osachepera. Common Sitima Yapamtunda mafuta komanso akhoza kuchepetsa mlingo wa mpweya utsi. Reviews a ziziyenda kuti galimoto ndi dongosolo mafuta jekeseni zambiri phokoso (palibe ngati khalidwe "kubangula", ngati injini yakale dizilo). "Common Sitima Yapamtunda" ali osiyanasiyana kuthamanga lamulo ndi mafuta jekeseni chiyambi mphindi.

chipangizo

Kapangidwe a dongosolo Common Sitima Yapamtunda ndi paipi dera. Pamene injini ikuchitika jekeseni mwachindunji kwa mafuta (i.e., mafuta umaperekedwa mwachindunji m'chipinda yamphamvu). Pali zinthu zingapo zimene imakhudzana ndi ntchito ya dongosolo Common njanji. ndi zigawo zimenezi? Loyamba ndilochokera pa kuthamanga mafuta mpope. Amagwiritsidwanso ntchito mu vavu dosing ndi kuthamanga yang'anira. Komanso, pali mafuta njanji ndi injector kamangidwe. Common Sitima Yapamtunda - dongosolo m'malo zovuta ndi kumvetsa mfundo zake ntchito, kuganizira makhalidwe a lililonse chigawo.

mpope

Choncho, kuthamanga mpope. limagwirira Izi ntchito kulenga ndi kuthamanga madzimadzi. Mlingo zimadalira injini katundu ndi rpm wa crankshaft lapansi. Monga mukudziwa, injini liwiro dizilo si malamulo ndi kutsegula kwa vavu fulumizitsa, ndicho gawo la mafuta amene amaperekedwa. Pakuti ili, ndipo akumana ndi kuthamanga mpope. chipangizo ndi m'malo zovuta izi amafotokozera - kwambiri mtengo chigawo galimoto dizilo (pa, kupatula mayunitsi zofunika, monga injini mkati kuyaka ndi PPC).

Yang'anira ndipo vavu Common Sitima Yapamtunda

Kodi chinthu ichi? vavu ntchito kulamulira kuchuluka kwa mafuta aperekedwe ku mpope. zinthu kandalama pamodzi ndi mpope. Palinso mafuta kuthamanga yang'anira. Iwo waikidwa mu njanji mafuta, ndipo akulamulira galimoto malingana ndi katundu.

limes

Limeneli liyenera amagwira ntchito zingapo. Izi kudzikundikira mafuta pansi kuthamanga oscillations mitigating kuthamanga ndi nozzles mafuta yogawa. Iyi ndi mbali ya chitetezo cha kudya.

nozzles

Dziwani kuti anthu ali ngati mafuta (injector), ndi injini dizilo. Komabe, kusiyana yaikulu - ndi mavuto kulenga. Mu ichi injector mlandu "Common Sitima Yapamtunda" komanso akulamulira kuchuluka kwa mafuta amene akudyetsedwa mwachindunji mu yamphamvu ya. mchitidwe The chikugwirizana mwachindunji limbikitsa lapansi. Pa nthawi, mitundu iwiri yosiyana ya nozzles:

• The piezo injectors ( "Bosch").
• Zamagetsi (sewerolo chachikulu - "Delfi").

Zikatero, kusowa mafuta amapangidwa pogwiritsa ntchito valavu solenoid. The piezo injectors ali ndi udindo timibulu wapaderawu. Liwiro zinthu izi ndi apamwamba, kotero iwo ali ofala. Komabe, kukonza Common yapamtunda (Jets) kutulutsa manja awo sizingatheke chifukwa zovuta za kapangidwe ndi sintha. Choncho, onse yokonza ntchito pa dongosolo akutsatiridwa yekha m'malo ogulitsira apadera. Izi ndi drawback waukulu wa magalimoto amenewa.

Kodi ntchito?

Ntchito ukulamulidwa dongosolo dizilo jekeseni dongosolo kulamulira. Atsopano monga actuators, zimatulutsa ndi ECU. Mogwirizana magawo onse - malo a accelerator, ndi coolant kutentha, kuchuluka kwa mpweya ndi ngakhale zikuchokera mpweya wa utsi (a lambda kafukufuku). Mokhudzana actuators ndi, ali tatchulawa nozzle limbikitsa, mpope mafuta, yang'anira ndipo mavavu. Kotero, momwe dongosolo ntchito? Kuchokera pa zizindikiro omwe amalamulira masensa adadziwa, dongosolo anapanga kuchuluka Napempha kwa mafuta. Iwo akudyetsedwa kudzera valavu metering. Mafuta ukufika mpope, ndiyeno kuthamanga ukupita mmwamba pa limbikitsa. zoipazi chofunika anapitiriza yang'anira wapadera. Panthawi ina, kompyuta analandira chizindikiro kwa injectors, ndi iwo anachita mu kutsegula njira inayake nthawi. Malinga akafuna ntchito injini, ndi kuthamanga mafuta angathe kukuthandizani kusintha dongosolo pamaziko a kafukufuku wa kachipangizo oxygen. Komabe, mothamanga ayenera kukhala laling'ono. zolakwika chidwi amasonyeza zolakwa ndi "Common Sitima Yapamtunda" dongosolo.

Mitundu ya jekeseni Common Sitima Yapamtunda

Ndi chiyani icho? Pali mitundu ingapo ya mafuta jekeseni mu dongosolo:

• Waukuluwo.
• Main.
• Sankhula.

Choyamba chikuchitika pamaso chachikulu kuti kuonjezera kuthamanga ndi kutentha mu chipinda kuyaka. Atengedwere mofulumira autoignition mlandu waukulu ndi kuchepetsa phokoso engine. Pre-jekeseni angakhale osiyana, malingana ndi chikhalidwe injini opaleshoni. Choncho, pa ulesi chifukwa amapangidwa kawiri. Ndi kuwonjezeka katundu - kamodzi. chisanadze jekeseni ndi sadatsatire pa katundu zonse. Cholinga cha jekeseni chachikulu - mwachindunji kupereka injini. Subtypes, iye si wogawanika. jekeseni zina akutumikira kuchepetsa utsi mpweya kawopsedwe. Choncho, popeza kachipangizo mpweya amalandira mauthenga pa kompyuta, ndiye amaperekedwa mbali ina ya mafuta. Zovulaza zinthu afterburned mu chothandizira ndi (izo amatchedwanso ndi dizilo particulate fyuluta).

Generation "Common Sitima Yapamtunda"

Dziwani kuti m'badwo woyamba wa dongosolo anaonekera mu chaka cha 1999. Iwo linanena bungwe kuthamanga 145 MPa. Patapita zaka ziwiri anabwera dongosolo m'badwo wotsatira (160 MPa). 3 Common Sitima Yapamtunda anayamba m'chaka 2005. Pa nthawi, magalimoto zili ndi dongosolo la "Common Sitima Yapamtunda" m'badwo wachinayi. The nozzles ntchito pa mavuto 220 MPa. N'chifukwa kwambiri chidwi linaperekedwa kwa zoipazi? The apamwamba zigoli, mafuta kwambiri ndi jekeseni yamphamvu ya. Choncho, kwa nthawi zina kwa nthawi kuzindikira kuti mphamvu ukuwonjezeka injini dzuwa.

Pomaliza

Kotero, ife tinapeza chimene mwachindunji dongosolo jekeseni, mmene anakonza komanso mmene chimagwirira ntchito. Dziwani kuti "Common Sitima Yapamtunda" ntchito magalimoto ambiri dizilo, makamaka ku Europe. dongosolo, ngakhale kapangidwe kake, mungathe yaikulu.
