Lub tshuab tso pa tawm yog tsim los tshem tawm cov khoom siv hluav taws xob los ntawm lub cav thiab tso tawm rau hauv ib puag ncig. Nyob rau tib lub sijhawm, lub suab nrov yuav tsum raug txo kom muaj kev txwv. Ib yam li lwm cov khoom siv, qhov system no muaj ntau lub ntsiab lus tseem ceeb, xws li lub qhov tso pa tawm thiab cov channel, lub twj tso kua mis, lub resonator, nrog rau kev sib txuas cov kav dej thiab cov clamps. Lub tshuab tso pa tawm muaj lub hauv paus ntsiab lus yooj yim thiab nkag siab ntawm kev ua haujlwm - cov pa pa tawm los ntawm cov raj xa dej nkag mus rau lub suab nrov ntxiv, thiab tom qab ntawd mus rau hauv lub ntsiab, thaum lub suab nrov thiab cov concentration ntawm cov khoom tsis zoo raug txo mus rau qhov siab tshaj plaws. Ntawm kev txaus siab yog lub internal qauv ntawm lub muffler. Cov tom kawg muaj ntau lub kaw lus thiab cov khoom sib faib, nyob rau hauv ib lub cev. Lub checkerboard kev npaj ntawm tag nrho cov "obstacles" nyob rau hauv txoj kev ntawm combustion khoom pab txhawb rau ib tug tseem ceeb poob ntawm lawv ceev. Raws li qhov tshwm sim, cov roj uas hu ua " ntsiag to" tau txais ntawm qhov hluav taws xob, uas tom qab yaj hauv huab cua.

Piv txwv li, ua tsaug rau cov cuab yeej no, ntau cov khoom tsim kev puas tsuaj (nitric oxide, hydrocarbons, carbon oxides) tau khaws cia thiab rov qab los. Cia peb saib ze dua ntawm cov nitrogen oxide rov qab mus rau cov khoom siv manifold. Lub ntsiab yog vim li cas rau tsim ntawm no compound yog qhov kub thiab txias nyob rau hauv lub combustion chamber. Qhov concentration ntawm cov khoom no tuaj yeem txo qis los ntawm kev ua haujlwm qis. Txoj kev yooj yim tshaj plaws thiab muaj txiaj ntsig zoo tshaj plaws los ua qhov no yog los ntawm kev xa rov qab qee qhov tso pa tawm. Xws li cov pa roj recirculation pab kom txo tau qhov kub thiab txias ntawm cov roj sib tov, tab sis cov muaj pes tsawg leeg ntawm cov tom kawg thiab qhov piv ntawm cov khoom tseem tsis hloov. Tsis tas li ntawd, qhov hloov pauv ntawm cov ntsuas hluav taws xob tuaj yeem suav tias yog qhov tsis tseem ceeb. Lub tso pa tawm ntawm ntau lub tsheb niaj hnub no muaj cov catalyst nyob rau hauv nws cov qauv, uas yog tsim los rau neutralize thiab purify pa emissions.

Lub hom phiaj tseem ceeb ntawm kev ua tsis zoo ntawm lub tsheb no tuaj yeem hu ua kev nce suab nrov thiab nce siab ntawm cov pa phem. Lub tshuab tso pa tawm, vim nws qhov chaw qis qis rau hauv av, tuaj yeem ua rau ib nrab lossis puas tag. Tsis tas li ntawd, kev tsav tsheb ntawm qhov chaw tsis sib xws yuav ua rau muaj kev ua txhaum ntawm qhov nruj ntawm qhov sib txuas. Tag nrho cov no ua rau poob ntawm kev ncaj ncees thiab, raws li, nce suab nrov ntawm koj lub tsheb. Nyob rau hauv lem, qhov tsis zooKev hloov pauv hauv cov khoom sib xyaw ntawm cov pa tso pa tawm tuaj yeem yog qhov tshwm sim ntawm kev teeb tsa tsis raug ntawm kev tswj hwm lossis kev sib kis ntawm cov pa tso pa tawm.

Lub tshuab tso pa kom ntev thiab siv tau zoo ua rau qee qhov kev xav tau ntawm kev ua haujlwm: kev sib txuas cov kav dej, resonator thiab muffler yuav tsum tsis txhob ncaj qha mus rau hauv kev sib cuag nrog lwm yam qauv ntawm lub tsheb. Qhov kev ceev faj no yuav ua kom tsis tsuas yog lub neej ntev ntawm kev tso pa tawm, tab sis kuj muaj kev nyab xeeb ntawm cov tshuab uas nyob ib sab.
