Lub hauv paus ntsiab lus ntawm lub cav tso pa system yog sau thiab tso tawm cov pa tawm, thiab tso cov pa tawm ntawm lub cav thaum txo cov pa phem thiab suab nrov ntawm cov pa pa tawm. Lub kaw lus muaj xws li tso pa tawm manifold, tso cov yeeb nkab, catalytic converter, tso qhov kub thiab txias sensor, tsheb muffler thiab cov yeeb nkab tso pa tawm.
Kev ua tsis tiav ntawm lub cav tso tawm tuaj yeem ua rau muaj teeb meem ntau yam hauv lub tsheb, yog li nws yog ib qho tseem ceeb kom nkag siab qhov ua rau tsis ua hauj lwm thiab yuav ua li cas xyuas nws. Cov hauv qab no yog qee qhov ua txhaum cai thiab kev tshuaj xyuas:
1. Pib thiab nres lub tsheb peb zaug ua ke, lossis tshem tawm qhov tsis zoo ntawm lub cav roj teeb thiab tos 30 vib nas this ua ntej txuas nws dua. Tom qab ua raws li cov txheej txheem saum toj no, xyuas seb lub cav ua txhaum lub teeb ntawm lub ntsuas hluav taws xob puas tseem nyob. Txoj kev no tsuas yog siv rau cov cav tsis raug cai.
2. Kev puas tsuaj rau cov pa oxygen sensor nyob rau hauv peb-txoj kev catalytic system los yog lom ntawm peb-txoj kev catalytic converter kuj yuav ua rau lub cav tso qhov system txhaum lub teeb rau illumination. Yog tias lub teeb no tshwm sim thaum tsav tsheb, thov kom qeeb tam sim ntawd thiab tsav mus rau qhov chaw pabcuam ze tshaj plaws rau kev tshuaj xyuas.
3. Yog tias lub tsheb nres thiab tsis tuaj yeem pib tom qab qhov teeb meem txhaum cai los, nws feem ntau yog vim tsis ua haujlwm ntawm lub twj tso kua mis roj lossis cov khoom siv hluav taws xob. Hauv qhov no, koj yuav tsum hu rau lub tsheb thauj khoom ncaj qha. Yog tias koj tuaj yeem tsav tsheb mus ntxiv, tab sis lub tsheb muaj cov tsos mob xws li kev tshee hnyav thiab tsis muaj peev xwm ua kom nrawm, qhov no yuav tsis tsuas yog tiv thaiv kev puas tsuaj ntxiv rau lub cav, tab sis kuj ua kom muaj kev nyab xeeb ntawm tus kheej ntawm tus neeg tsav tsheb thiab cov neeg caij tsheb.
