Variable Compression Engine / Variable Compression Engine Operation

Yakaunzwa naInfiniti, asi kwenguva refu ichifungidzirwa nevamwe vagadziri vazhinji, iyo inochinja yekumanikidza injini yave kuwanikwa mumusika wemotokari.

Kudzvinyirira?

Chokutanga pane zvose, zvakakosha kuziva kuti chii chinonzi compression reshiyo yeinjini. Uhwu hukama hwakareruka pakati pehuwandu hwemhepo isina kudzvanywa (apo piston iri pazasi: pasi yakafa pakati) uye kana yakamanikidzwa (apo piston iri kumusoro: kumusoro kwakafa pakati). Kumhanya uku hakuchinji, nekuti nzvimbo yepiston pazasi kana kumusoro inogara yakangofanana, saka matenderedzwa anobva panzvimbo A (PMB) kuenda kunongedza B (PMH).

Pane iyi yekare V-injini, tinoona TDC uye PMA panguva imwe chete. Mhepo yakadzvanywa kuruboshwe uye mhepo isina kudzvanywa kurudyi

PMB: piston pazasi

TDC: piston iri kumusoro

Iyo mukana weiyo yakakwirira compression reshiyo?

Ziva kuti kana iwe uchiwedzera iyo compression reshiyo, ndipo paunowedzera kugona kweinjini, saka inova shoma simba nzara. Nokudaro, chinangwa chevakagadziri ndechekusimudza zvakanyanya sezvinobvira. Nekudaro, zvine musoro kuti iyo yakanyanya kudzvanywa, iyo yakakura mutoro pazvinhu zvema mechanical, saka kungwarira kunofanirwa kutorwa kuti urege kuipfuura. Uye zvakare, kudzvanya gasi kunowedzera tembiricha yayo, inova musimboti wemuviri kuseri kweinjini dzedhiziri. Pane imwe nhanho, kana tikamanikidza peturu yakawandisa mugasi (saka mhepo), tembiricha ichakwira zvakanyanya zvekuti peturu ichapisa yega kunyange kenduru isati yatungidza ... Ipapo kupisa kuchaitika nekukurumidza. , zvichikonzera kukanganisa kumasilinda (asiwo mavharuvhu) uye kukonzera kugogodza.

Iko kugogodza chiitiko kuchawedzera nehuwandu hwemafuta, ndiko kuti, kana uchitakura (kana iwe uchinyanya kudzvanya pedal, mafuta akawanda anoiswa jekiseni).

Muchiitiko chakadaro, chakanakira chingava chepamusoro compression reshiyo pamutoro wakaderera uye reshiyo "inodzikama" zvishoma kana yakadzvanywa zvakasimba.

Variable Compression Ratio: Asi Sei?

Kuziva kuti chiyero chekumanikidza chinoenderana nehurefu hunogona kufamba nepiston (TDC), zvino zvakakwana kuti ukwanise kushandura kureba kwetambo dzekubatanidza (idzi ndidzo "tsvimbo" dzinobata piston uye dzinobatanidza kune crankshaft). Iyo sisitimu, yakagadzirwa neInfiniti, saka inoshandura hurefu uhwu nekuda kweiyo electromagnetic system, saka cranks zvino inogona kuwedzerwa! Iwo maviri anogoneka reshiyo anozoshandurwa kubva pa8: 1 kusvika 14: 1, mushure meiyo gasi / mafuta musanganiswa unogona kudzvanywa kusvika kasere kana gumi nemana, zvichiita mutsauko mukuru!

Isu tiri kutaura nezve inofambiswa crankshaft, connoisseurs vanokurumidza kuona kuti haina kutaridzika seyatakajaira kuona.

Izvi zvinopesana nejini yakajairwa, iyo matanda ekubatanidza ari nyore matanda akabatanidzwa kune crankshaft.

Heano mavara maviri akasarudzwa neInfiniti kuti amiririre maTDC maviri anobvira.

Pamutoro wakaderera, chiyero chichava pahupamhi hwayo, kureva, 14: 1, nepo pamutoro wakakwira inodonha kusvika ku8: 1 kudzivirira kupisa kwega kwega spark plug isati yaita basa rayo. Saka isu tinofanirwa kutarisira kuona kuchengetedza kana uine tsoka yakareruka, kutyaira kwemitambo pakupedzisira hakuchinje sezvo kumanikidza kunova "kwakajairika" zvakare. Izvo zvinoramba zvichionekwa kana rudzi urwu rwekufamba crank ruchavimbika mukufamba kwenguva, nekuti kuwedzera zvikamu zvinofamba kunogara kune njodzi ...

Mhoroi Ndinokutendai nokuda kwezvinyorwa zvenyu zvose zvinonyatsotsanangurwa uye zvakandidzidzisa zvakawanda. Kana ndikanzwisisa nemazvo, injini dzepeturu dzave nejekiseni rakananga, sedhiziri. Saka nei tichiramba tichi "kudzora" chiyero chekumanikidza kudzivirira kuzvipisa kana mweya wakamanikidzwa usina mafuta? Il J. 5 reaction (s) kune ichi chirevo: Enkidu (2017-10-17 21:18:18): Zvinosiririsa kuti chinyorwa chinonyorwa pasina ruzivo rwechidzidzo. Iyo inosiyana yekumanikidza injini inoshanda muFrench uye kunyangwe "ardà © chois"!

Jesse (2021-10-11 17:08:53): Panyaya iyi, uri kutaura nezve iyo compression ratio inogona kuwedzera kubva pa8: 1 kusvika 14: 1 nekuda kweiyo system. Zvinoita sei kuti kudzikisa reshiyo yekumanikidza (kudzika kusvika 8: 1) inopa simba rakawanda? Handizvo here zvimwe? Ndinoyeuka kuti mumakwikwi takaita basa duku pazvikamu zveinjini kuitira kuti tiwedzere zvishomanana kuwedzera kwereshiyo uye nokudaro kuwedzera simba rejini. Iyo yakakwira iyo compression reshiyo, iyo yakareba piston sitiroko uye nekudaro yakakura iyo oxidizer / jekiseni remafuta reshiyo, saka zvirinani kushanda uye saka simba rinounzwa, handiti?
