Chii chinonzi compression test?

Muedzo wekumanikidza unoratidza mamiriro ezvikamu zveinjini yako uye unogona kukuchengetedza mari pakutenga injini itsva.

Nepo injini dzemazuva ano dzinopisa dzichiitwa dzakasimba kupfuura nakare kose, nekufamba kwenguva zvikamu zviri mukati zvinogona uye zvichasakara. Sekuziva kunoita varidzi vemota vazhinji, injini inogadzira simba nekudzvanya hutsi hwehutsi mukati mekamuri yekupisa. Izvi zvinogadzira imwe huwandu hwekumanikidza (mumapaundi pacubic inch). Kana zvikamu zvakakosha, zvinosanganisira mhete dzepiston kana silinda musoro zvikamu, zvikapera nekufamba kwenguva, iyo compression reshiyo inodiwa kupisa mafuta uye mweya zvinodzikiswa. Kana izvi zvikaitika, zvakakosha kuti unzwisise maitiro ekuita bvunzo yekumanikidza nekuti inhanho yekutanga kuongorora nekugadzirisa injini.

Mune ruzivo rwuri pazasi, tichavhara kuti bvunzo yekumanikidza chii, zvimwe zvikonzero zvakajairika zvaungade kuti sevhisi iyi iitwe, uye maitirwo anoitwa sevhisi nenyanzvi.

Chii chinonzi compression test?

Iyo yekumanikidza bvunzo yakagadzirirwa kutarisa mamiriro einjini yako chitima chevhavha uye mhete dzepiston. Kunyanya, zvikamu zvakadai semavharuvhu ekudya uye ekupera simba, zvigaro zvevharuvhu, magasi emusoro, uye mhete dzepiston zvikamu zvakajairika zvinogona kupfeka uye kuita kuti compression idonhe. Nepo imwe neimwe injini nemugadziri akasiyana uye aine akasiyana anokurudzirwa kudzvanya mazinga, kazhinji compression pamusoro pe100 psi ine isingasviki 10 muzana musiyano pakati peiyo yakaderera uye yepamusoro yekumisikidza inoonekwa seyakagamuchirwa.

Kuyedzwa kwekudzvanya kunosanganisira kushandiswa kwegeji yekumanikidza inoiswa mukati me spark plug gomba rehumburumbira yega yega. Sezvo injini inodonha, geji icharatidza huwandu hwekumanikidza kuri kugadzirwa muhumburumbira yega yega.

Ndepapi paungade cheki yekumanikidza?

Mumamiriro ezvinhu akajairwa, bvunzo yekumanikidza inokurudzirwa kana mota yako ichiratidza zvinotevera zviratidzo:

• Iwe unoona utsi huchibuda mu exhaust system kana iwe uchimhanyisa kana kuderedza.
• Mota yako haimhanyire zvakajairwa kana kuita seine usimbe.
• Wakamboona vibration ichibva kuinjini yako paunenge uchityaira mumugwagwa.
• Upfumi hwemafuta hwakaipa kudarika nguva dzose.
• Iwe unowedzera mafuta kakawanda kupfuura nguva dzose.
• Injini yemotokari yako yanyanya kupisa.

Ko compression test inoitwa sei?

Kana iwe uri kufunga nezve kuita bvunzo yekumanikidza, pane mashanu akakosha matanho ekutevera ekutevera kuti uve nechokwadi chekuti yakarurama sezvinobvira. Gara uchitarisa kune mirairo inokurudzirwa yega yega compression tester yaunoshandisa kuve nechokwadi chechokwadi.

1. Pisa injini kuti ishandise tembiricha. Piston mhete, zvigaro zvevharuvhu, uye zvimwe zvakakosha zvinogadzirwa kuti zviwedzere kana zvapiswa, izvo zvinogadzira iyo inodiwa compression ratio mukati meinjini. Kana iwe ukaita bvunzo yekumanikidza pane inotonhora injini, kuverenga kuchave kusina kururama.

2. Misa injini zvachose. Misa injini kutarisa compression. Iwe unofanirwawo kubvisa peiri pombi relay switch uye magetsi ekubatanidza kune coil pack. Izvi zvinodzima moto wekudzimisa uye nemafuta ekupa system, izvo zvinoita kuti injini isabate moto panguva yekuyedzwa.

3. Bvisa spark plug waya. Iva nechokwadi chekuabvisa kubva kune ese ma spark plugs, wobvisa ese ma spark plugs.

4. Isa injini yekumanikidza geji mugomba rekutanga re spark plug. Iwe unozoda kutarisa compression mune yega silinda. Zviri nani kutanga necylinder iri padhuze newe woshanda wakananga kumashure, wozotevera kune rimwe divi (kana zvichibvira) kusvika wapedza cheki yega yega yekumanikidza.

5. Crank injini kwenguva pfupi. Ita kuti mumwe munhu akubatsire nekubatidza kiyi painjini kakawanda mukati memasekonzi matatu kusvika mashanu. Panguva imwecheteyo, iyo yakanyanya kudzvinyirira kukosha inofanira kuoneka pane yekumanikidza gauge. Nyora iyi nhamba yepamusoro pasi pabepa resilinda yega yega uye dzokorora danho iri pahumburumbira imwe neimwe inotevera.

Mushure mekunge mapedza ese macylinders painjini yako, iwe uchada kutarisa pamusoro penhamba. Iwe unogona kutarisa kune bhuku rebasa remotokari yako, gore, kugadzira uye modhi kuti uone kuti nhamba dzinofanirwa kutaridzika sei. Sezvatakataura pamusoro apa, iyo inowanzogamuchirwa kukosha iri pamusoro pe100 psi. Chinhu chakakosha chekufunga nezvacho musiyano pakati pehumburumbira imwe neimwe. Kana imwe yadzo inopfuura gumi muzana mudiki pane mamwe, panogona kunge paine dambudziko rekumanikidza.

Muedzo wekumanikidza inogara iri nzira yakanaka yekuona kana zviratidzo zvauri kuona zvine chekuita nekukuvara kweinjini. Zvisinei, kana kudzvinyirirwa kwejini kunowanikwa kwakaderera, kuwedzeredza kukuru kana, mune dzimwe nguva, kutsiva kwakakwana kwejini kunodiwa. Chakakosha kuita kuti nyanzvi makanika aite bvunzo yekumanikidza kuti vatarise zvabuda uye vakurudzira kugadzirisa kana kutsiva zvine musoro wemari.
