Ubwoko butandukanye bwo gutwika bubi butanga imizi.

Gutwika gukennye byatewe no guteranya ibintu bitaringaniye biri muri moteri ya byinshi biteye inshinge. Gutwika nabi byatewe nabakire cyangwa bavanze amavuta muri silinderi imwe iterwa namavuta mato cyane cyangwa ngo ashizwemo na buri nurongora (nozzle irahagaritswe cyangwa ngo irahagarike). Igihe ikigereranyo cy'ikirere kivanze mu kirere givanze muri silinderi cyangwa lisansi kinini kirenze akaga, gutwika mu kirere bimaze kubaho igihe igipimo cyo gutwika ikirere cyatewe no gutesha agaciro amavuta atari yo. Muri rusange, birashobora gucirwa urubanza no gukuraho ibishoboka byose byatewe na sisitemu yo gutwika, gutwika umuvuduko ukabije k cylinder na vacuum bitwaje silinderi imwe. Gutera inshinge za lisansi. Imodoka ya Oscilloscope irashobora gukoreshwa mugukuraho umuriro ukennye watewe na sisitemu yo gutwika hamwe nigitutu cya silinderi (kugirango ushake umuriro mubi byatewe na sisitemu yo gutwika 1. To eliminate the vacuum leakage related to individual cylinders, propane (intake manifold, carburetor pad, etc.) is usually added to the area or surrounding where vacuum leakage may occur, and at the same time, as mentioned before, the signal waveform of oxygen sensor is observed from an oscilloscope to achieve the goal. Mubisanzwe, muri moteri yamavuta menshi, niba muburyo bwinoro bwatewe nubwombo a, b, na c ntishobora kugaragazwa, noneho amahirwe yo kutaringaniza bitera akajagari ka Ssubifor ya ogisijeni irashobora kugenwa. Amategeko yo gucira urubanza akajagari ka ogisijeni niba hari akajagari kagaragaye ko kunanirwa kwa moteri ya ogisijeni, mubisanzwe bizajyana no kunanirwa kwa moteri ya ogisijeni, mubisanzwe bizajyana no kunanirwa kwa moteri ya ogisijeni, mubisanzwe bizaherekezwa no kunanirwa kwa moteri ya regisije kandi bigeragezwa bisubirwamo (urugero, gukomanga kuri buri Cylinder gutwita). Mubisanzwe, niba akajagari kagaragara, amakosa ya moteri amaherezo afitanye isano nimpinga zitandukanye ku muhengeri, hamwe nikosa rya moteri ritagaragara kugirango rihuze amakosa ya moteri, ntibushobora kuvaho mu gusanwa. Muri make, itegeko ryo guca imanza ni: Niba bishoboka ko nta vacuum yashizweho mu gufatanya cyane, hamwe n'ibice bya moteri birasanzwe, hanyuma umuvuduko wa moteri uringaniye, hanyuma akajagari gashobora kwemerwa cyangwa bisanzwe.
