Kodi kukhazikitsa poyatsira nthawi

Akuyendera kuti ntchito zimenezi, monga padzuwa la poyatsira ndi, muyenera mutidziwe ndi ena matanthauzo. Mwachitsanzo, poyatsira nthawi. Amadziwika kuti pa nthawi imene pisitoni apatsira psinjika sitiroko, ndi crankshaft zimapangitsa kukhota theka, izo zimayenda ndi madigiri 180. Izi nkhawa osati psinjika sitiroko, pamene ena onse ndipo motero wathunthu opaleshoni mkombero wa injini anayi sitiroko zimapangitsa kusintha awiri kapena madigiri 720.

Pali chinthu monga ya octeni chiwerengero cha mafuta. Ife sitikhala kupita tsatanetsatane wa mmene kuyeza, n'kofunika kuti ndi osiyana. Tsopano, mafuta ndi osiyana liwiro octeni poyatsira ndi osiyana kwambiri. Ngati nthawi poyatsira wayikidwa yeniyeni imene pisitoni ndi pa TDC, ndi poyatsira kumachitika pa nthawi pamene Iye akupita pansi zochita za inertia wa flywheel lapansi.

Pofuna kupewa izi zisachitike, ndi osakaniza kuphulika zinachitika pa malo pamwamba akufa, nthawi poyatsira akukonzerani. Mwachitsanzo, ngati pisitoni Vaz-2106 ukufika TDC 4-5 mm, ndi crankshaft mpaka wathunthu 180 aphonya madigiri 10. Ngati odulidwa woyamba kukula kwa mamilimita 2-3, ndiye wachiwiri kusanduka madigiri 5. Izi ndi kumathandiza kupeza ngodya zabwino ambiri, amene chagwiritsidwa ntchito AI-80 ndi AI-92, motero.

Tsopano mwachindunji naonetsere poyatsira. Taganizirani ndondomeko imeneyi ndi chitsanzo chabwino cha dongosolo sanali kukhudzana, kupewa mavuto ndi kusiyana pochita lapansi. Choyamba muyenera kudziwa psinjika sitiroko mu yamphamvu woyamba. Izi zachitika ntchito ubweya, amene anatseka mphamvu pulagi dzenje m'mutu, ndiye zimayenda pang'onopang'ono kwa ratchet crankshaft. Ngati yamphamvu psinjika zabwino, ubweya ayenera kuuluka oyambirira mu kuzungulira.

Monga ulamuliro, ndi crankshaft pulley pa chikuto ali chizindikiro a. Izi ndi poyatsira nthawi. Iwo zizigwirizana kumathandiza kupeza ngodya zabwino pamwamba, komanso TDC Nayenso malangizo a kasinthasintha. Malinga ndi chizindikiro atsopano kawirikawiri poyera poyatsira kwa AI-95 ndi AI-98, kotero ntchito chizindikiro ichi ndi wokongola osowa.

Pambuyo kuika crankshaft ku malo limagwirizana kulemba pa wogulitsa poyatsira, zosiyanasiyana zopangidwa ndi zitsanzo, iwo ali osiyana, ndi powerengetsera ndi anaikapo mu kulandira kagawo, kenako lokhazikika.

Koma ndikuona kuti poyamba poyera poyatsira nthawi sangakhale komaliza.

More mosamala kusintha kwa poyatsira ndi ikuchitika pambuyo injini akuyamba, zochangamutsa mwakale kutentha opaleshoni, ndipo pambuyo yoyenera kusintha kwa carburetor wa ku ulesi. Pakuti mtundu uwu mu lachitatu zida liwiro 35-40 Km / h, ndiye wachinayi kusinthana. Pambuyo detonation mwachidule muzichita, amene Mwamsanga masekondi asanu. Ngati icho chikukhala kwa nthawi yaitali, m'pofunika kusintha wogulitsa nyumba motsogozedwa kasinthasintha wa wodzigudubuza, kapena mosinthanitsa, ngati kugogoda kulibe.

Pomaliza, tiyenera kuti nepravlny pasadakhale njingayo, makamaka molawirira kwambiri, chifukwa mu kuwononga kwambiri ndi kulumikiza ndodo-pisitoni gulu, monga Mwachitsanzo, tithe kumvetsa kumasulira pamwamba porshpaltsa ndodo mutu kapena khosi crankshaft pa pansi.
