Chii chinonzi injini block (uye chinoitei)?
Iyo injini block, inozivikanwawo se cylinder block, ine zvese zvakakura zvikamu zvinoumba pasi peinjini. Pano crankshaft inotenderera, uye mapistoni anofamba achikwira nekudzika mumasilinda mabhora, anotungidzwa nekupisa kwemafuta. Mune mamwe magadzirirwo einjini, inobatawo camshaft.
Kazhinji inogadzirwa nealuminium alloy pamotokari dzemazuva ano, kazhinji inogadzirwa nesimbi yakakandwa pamotokari dzakura nemarori. Kuvakwa kwayo kwesimbi kunoipa simba uye kugona kufambisa zvakanaka kupisa kubva kumabatiro ekupisa kuenda kune yakabatanidzwa yekutonhodza system. Iyo aruminiyamu block inowanzo ine yakatsikirirwa simbi bushing yemapiston bores kana yakakosha yakaomeswa coating inoiswa kumabores mushure mekugadzira.
Pakutanga, bhuroka raingova simbi yakabata zvibhorani zvehumburumbira, bhachi remvura, mapaseji emafuta, uye crankcase. Iri bhachi remvura, sezvarinombodanwa dzimwe nguva, igadziriro isina chinhu yematanho ayo inotonhorera inotenderera muinjini block. Bhachi remvura rinokomberedza masilinda einjini, anowanzoita mana, matanhatu, kana masere, uye ane mapiston.
Kana musoro wecylinder wakamisikidzwa kumusoro kwecylinder block, mapistoni anokwira nekudzika mukati memasilinda uye anotenderedza crankshaft, inozopedzisira yatyaira mavhiri. Pani yemafuta iri pazasi pecylinder block, ichipa dura reoiri kubva kwairi pombi yeoiri inogona kudhirowa nekupa nzira dzemafuta uye zvikamu zvinofamba.
Injini dzakatonhorera nemhepo, dzakadai seyekare VW ina-cylinder injini uye yekutanga Porsche 911 mitambo yemotokari injini, haina chaizvo cylinder block. Seinjini yemudhudhudhu, crankshaft inotenderera mumakesi ejini akasungwa pamwechete. Yakasungirirwa kwavari yakaparadzana ribbed cylindrical "jugs" umo mapistoni anofamba achikwira nekudzika.
Matambudziko akajairika nemabhuroki enjini
Injini yebhuroko ihombe, yakanyatsogadzirwa chidimbu chesimbi chakagadzirirwa kugara hupenyu hwemotokari. Asi dzimwe nguva zvinhu zvinoshata. Heano akanyanya kutadza cylinder block:
Injini yekunze inotonhorera inodonha
Divi remvura / antifreeze pasi pejini? Izvi zvinogona kukonzerwa nekudonha kubva papombi yemvura, redhiyeta, hita core, kana hose yakasununguka, asi dzimwe nguva inobva pajini block pachayo. Iyo block inogona kutsemuka nekudonha, kana plug inogona kusunungura kana kuita ngura. Frost plugs inogona kutsiviwa nyore nyore, asi makatsemuka kazhinji haarapike.
Silinda yakasakara/yakatsemuka
Pakupedzisira, mushure memazana ezviuru zvemamaira, madziro emasilinda akatsetseka anopera kusvika padanho rekuti mhete dzepiston dzisisakwane zvakanaka. Muzviitiko zvisingawanzoitiki, kuputika kunogona kuumba pamadziro e-cylinder, izvo zvinokurumidza kutungamirira kudiwa kwekugadzirisa injini. Masilinda akasakara anogona kufinhwa zvakanyanya kuti agare mapistoni akawandisa, uye mupini (kana mualuminium zvidhinha) masimbi esimbi anogona kuiswa kuita kuti silinda madziro akwane zvakare.
Porous injini block
Inokonzerwa nekusvibiswa kwakaunzwa musimbi panguva yekugadzira, voids mukukanda kazhinji haikonzeri matambudziko kwenguva refu. Pakupedzisira, chivharo chisina kuumbwa zvakanaka chinogona kutanga kudonha uye kudonhedza chero oiri kana inotonhorera kubva munzvimbo yakakanganisika. Iwe haugone kuita chero chinhu kune porous injini block nekuti ichave yakaremara kubva pazuva rainokandwa. Nekudaro, chero kuvuza kunogona kuitika nekuda kweiyo porous block kunofanirwa kunge kuri kudiki, uye kana ikawanikwa panguva yewaranti yemugadziri, mota inofanira kutsiviwa pasina muripo.
