I-camshaft egugile - izimpawu

Izimoto zenziwe ngenani elikhulu lezingxenye, ukusebenza okuhambisanayo okubhekele ukusebenza kahle kwezinhlelo ngazinye. Enye yezinto ezibaluleke kakhulu uhlelo lokusabalalisa igesi nge-camshaft. Nguye ukuthi sizonikezela ukungena kwanamuhla - sizobheka ukuthi yiziphi izimpawu ezinikezwa i-camshaft egugile, iyini ukuvuselelwa kwayo nokuthi yiziphi izinjini ezisengozini kakhulu.

Uzofundani kulokhu okuthunyelwe?

• Yini okufanele ukwazi nge-camshaft?
• Yiziphi izimpawu zokugqoka i-camshaft?
• Kubukeka kanjani ukulungisa?
• Indlela yokwelula impilo ye-camshaft?

Ngikhuluma nje

I-camshaft iyisici esibalulekile sesistimu yokusabalalisa igesi, efanelekile, phakathi kwezinye izinto, ukunikezwa okwanele kwengxube yamafutha enjini. Ukwenqaba kwakhe kuhlotshaniswa nezimpawu zesici. Kodwa-ke, i-roller egugile ingaxilongwa futhi ilungiswe i-bodyshop yochwepheshe.

I-Camshaft - iyini le ngxenye?

Ngaphansi kwe-hood yezimoto zethu, singathola amayunithi amaningi nezingxenye ezinesibopho sokusebenza kahle kwenjini yokushayela. Ezinye zazo zilula uma kuqhathaniswa. Lokhu kungasidukisa ngokusebenza kwazo kanye nomsebenzi wazo. Enye ingxenye enjalo engabonakali i-camshaft. Iyingxenye yesistimu yesikhathi kanye nemisebenzi yayo eyinhloko (kanye nezinye izingxenye zesistimu) ihlanganisa:

• ukuqinisekisa ukutholakala kwengxube yamafutha omoya enjinini;
• ukulamula ekugcobiseni injini;
• i-ignition drive, iphampu yamafutha, iphampu kawoyela noma iphampu yamafutha anomfutho ophezulu.

I-camshaft ifakwe okubizwa ngamakhamera avula futhi avale ama-valve lapho i-shaft iphenduka, iqinisekisa ukunikezwa kwengxube kaphethiloli kanye nokukhipha igesi yokuqeda... Lokhu kucindezela kuma-valve kanye nokunyakaza okujikelezayo kwe-shaft kudala ukungqubuzana okuthi, ngokugcotshwa okunganele nokumelana okuphansi kokulayisha impahla, kusho ukugqoka ngokushesha. Inkinga yokugcoba enganele ingavela ezintweni ezimbalwa, njengemigqa yokukhipha uwoyela emincane kakhulu (bese iphampu kawoyela ilahlekelwa ukusebenza kwayo kwasekuqaleni) noma ukugcwalisa idrayivu ngezinto zokugcoba ezingahlangabezani nezincomo nezimfuneko zomenzi.

Lezi zimo ezingenhla zibaluleke kakhulu camshaft ezinjinini eziyi-1.9 TDI PD, i.e. iyunithi enama-injection eyunithi ye-Volkswagen, acushwa ikhamera eyengeziwe ku-camshaft. Ezinye izinjini ezizishaya isifuba nge-camshaft yezimo eziphuthumayo zihlanganisa: PSA 1.6 HDI kanye nezinjini ezingu-2.2 SkyActiv-D ezifakelwe ukukhetha izinhlobo zeMazda ngaphambi kuka-2014.

Amakhamera e-Camshaft nawo aguga ngaphansi kwethonya ukungafani kwezimo zamafutha enjini (isibonelo, ukusetshenziswa kwamafutha awuketshezi kumayunithi alayishwe kakhulu), ukuguga kwesilungisi se-hydraulic slack, izingalo ze-rocker ezigugile, noma imayela eliphezulu. Kwesinye isikhathi ukwehluleka kungenzeka futhi ngenxa amaphutha wokuhlanganisa shaftnakuba izimo ezinjalo ziyivelakancane.

Yiziphi izimpawu zokugqoka i-camshaft?

I-camshaft egugile ikhiqiza izimpawu eziqondile okungafanele zibe yinkinga ukuze umakhenikha onolwazi azibone. Ngokuyinhloko ukusebenza okungajwayelekile kwemoto yokushayela, ukulahlekelwa okuphawulekayo kwamandla enjini nomsindo wedizili lapho ushayela ngesivinini esiphezulu. Vakashela ishabhu ukuze uthole ukuxilongwa kochwepheshe kwesimo serola. Nokho, kuwufanele ukwazi ukuthi kwezinye onobuhle imoto singazama ngokuzimela ukunquma isimo camshafts. Lokhu sikwenza ngokubheka ikepisi yokugcwalisa uwoyela engasikiwe. Ngakho, singabona ucezu lwekhamera eyodwa noma ngaphezulu.

Kuyini ukuvuselelwa kwe-camshaft?

I-camshaft egugile ingashintshwaikakhulukazi uma kuyinsimbi. Kulokhu, kusetshenziswa indlela yokubheka phezulu, i.e. ukubekwa kongqimba lwensimbi encibilikisiwe endaweni encibilikisiwe. Ukunikeza i-roller amandla adingekayo, ingaphansi kokushisa nokwelashwa kwamakhemikhali. Ukuvuselelwa kwe-roller kuvame kakhulu kubantu asebekhulile ukuze kuncishiswe izindleko zenkonzo. Ukulungiswa kwe-trunnion eyodwa kuzosibiza i-50-70 PLN, uma singakhulumi ngenjini enekhanda le-valve engu-16 - kulokhu sizokhokha i-500-700 PLN ye-shaft. Intengo yeshaft yasekuqaleni yenjini enamasilinda amane ingaphinda kabili leyo.

Indlela yokuvimbela ukugqoka ku-camshaft?

Okokuqala, ake sikhumbule izinguquko ezivamile zikawoyela kanye nokusetshenziswa kwezinto zokugcoba ezisezingeni eliphezulu. Kubalulekile futhi ukusebenzisa izihlungi ezinhle zikawoyela njengoba izindawo ezishelelayo zijwayele ukungcoliswa uwoyela, njengezinhlayiya zensimbi. Kufanele futhi uqaphele injini ebandayo - ama-camshafts akude kakhulu ne-pan kawoyela, ngakho-ke aqala ukugcotshwa njengenye yezingxenye zokugcina ngemuva kokuguqula ukhiye ekushiseni.
