X-pipe ua tauhloovYuav ua li cas lub tso pa ntws thiab suab, tab sis seb nws "nce horsepower" nyob ntawm qhov hnyav ntawm lub cav, qhov seem ntawm qhov tso pa tawm, cov yeeb nkab txoj kab uas hla, muffler / resonator xaiv, thiab - tseem ceeb tshaj - seb qhov kev teeb tsa thawj zaug yog kev txwv.
1) X- yeeb nkab ua tau dab tsi
X- yeeb nkab yog hom kev sib txuas ntawm cov yeeb nkab sib txuas uas cov pa pa tawm los ntawm ob lub tsev txhab nyiaj sib koom ua ke hauv "X" kev teeb tsa. Nws lub tswv yim tseem ceeb yogtso pa tawm pulse sib cuam tshuam:
Thaum lub cav ua haujlwm, txhua lub tog raj kheej / lub txhab nyiaj tsim cov pulses siab.
Hauv qee qhov kev tso pa tawm, cov pulses tuaj yeem pab tautxo backpressurethiab txhim kho cov nyhuv scavenging (feem ntau piav raws li "ntws" zoo dua los yog cov dej siab zoo dua).
X- yeeb nkab tuaj yeem txhawb nqa qhov kev faib tawm ntau dua ntawm cov tsev txhab nyiaj thiab tuaj yeem txo qhov "qhov taw tes" qhov twg cov pulses cuam tshuam tsis zoo hauv H- yeeb nkab lossis Y- cov yeeb nkab yooj yim.
Txawm li cas los xij, qhov no tsis yog khawv koob -pulse tuning yog rhiab heev rau:
Lub cav hluav taws xob xaj thiab RPM ntau yam,
tso pa tawm thawj/secondary lengths,
converter / midpipe qhov chaw,
seb koj puas tseem muaj cov khoom txwv (tshwj xeeb tshaj yog catalytic converters).
2) Horsepower vs "xav nrawm dua": qhov tshwm sim tiag tiag yog dab tsi?
Thaum X- yeeb nkab pab
X- yeeb nkab yuav muaj feem ntau yuav qhia tau tias muaj txiaj ntsig zoo thaum:
lub Hoobkas tso los yog tam sim no aftermarket system muajntws tsis sib xwsnruab nrab ntawm cov tsev txhab nyiaj,
koj twb tau siv lub freer - ntws teeb (txoj kab uas hla loj, zoo mufflers/cav tsim),
koj lub suab (ECU / ECM) thiab huab cua / roj lub hom phiaj tuaj yeem ua kom zoo dua ntawm kev txo qis,
koj tab tom pom backpressure/pulse txwv ntawm dyno/logging data.
Nyob rau hauv cov ntaub ntawv no, "horsepower nce" feem ntau yog me me tab sis tiag tiag- feem ntau piav raws li kev txhim kho nyob rau hauv nruab nrab - mus rau - siab RPM ua pa los yog throttle teb.
Thaum nws yuav tsis nce horsepower
X- yeeb nkab feem ntau tsimme ntsis kom tsis muaj horsepower ncethaum:
qhov seem ntawm qhov tso pa tawm tseem yog qhov txwv tsis pub tshaj (piv txwv li, cov kav dej me me, txwv tsis pub mufflers, lossis tsis muaj peev xwm catalytic converters),
lub cav tswj tsis tu ncua kom phim cov yam ntxwv ntawm cov pa tshiab,
X- yeeb nkab hloov pauv hloov pauv tab sis tsis txo qis tag nrho lub cev rov qab muaj txiaj ntsig.
Hauv cov xwm txheej no, qhov kev hloov pauv pom tau tshaj plaws yuav yogsuab, drone yam ntxwv, thiab tag nrho throttle xav, es tsis yog loj ncov zog nce.
3) Qhov loj tshaj plaws yog "system" (thiab lub suab)
Txawm hais tias X- yeeb nkab txhim kho cov mem tes scavenging, tiag tiag horsepower feem ntau xav tau tias:
lub cav tso cai rau kev khiav hauj lwm hauv lub qhov rais airflow, thiab
ignition timing/air-fuel ratios yog tsim nyog rau tus tshiab pa backpressure thiab EGT (kua pa kub) tus cwj pwm.
Yog vim li cas qee lub tsheb qhia:
pom pom lub zog txhim kho tom qab hloov pauvntxivECU calibration zoo,
thaum lwm tus pom:
qhov tseem ceeb tib dyno tus lej thiab tsuas yog lub suab sib txawv.
4) Installation cov ntsiab lus tseem ceeb
Tsis yog tag nrho X- cov kav dej sib npaug. Kev lag luam- ntse, koj yuav tsum xav txog:
Txoj kab uas hla(me me dhau=txwv; loj dhau tuaj yeem ua mob nrawm thiab khawb hauv qee qhov RPM)
Ua ke ntev thiab geometry(muaj feem cuam tshuam rau lub sijhawm pulse)
Khoom thiab thickness(durability thiab resonance zaus)
Cat tso(hom crossover cuam tshuam li cas siab pulses cuam tshuam nrog catalysts)
O2 sensor bung qhov chaw(Qhov kev tso kawm tsis raug tuaj yeem ua rau kev tsav tsheb lossis kev nyeem cov sensor tawm mus rau qhov ntau)
5) Yuav ua li cas kom tau raws li qhov ua tau zoo
Rau feem ntau txoj kev tsim, ib qho X- yeeb nkab feem ntau muab tso ua ib qhokev ua haujlwm + suabhloov kho dua li qhov lav "bolt-ntawm horsepower" daws. Qhov kev cia siab tsim nyog yog:
Cov txiaj ntsig me methaum lwm cov pa tawm thiab lub suab txhawb nws,
Tsis muaj lub siab loj horsepower ncethaum lub system tseem txwv rau lwm qhov,
Txhim kho tus cwj pwm(ntau dua txawm tias tso tseg, qee zaum tsawg dua drone, qee zaum zoo dua midrange teb).
6) Qhov zoo tshaj plaws kom paub txog koj lub tsheb tshwj xeeb
Vim tias cov txiaj ntsig sib txawv heev, txoj hauv kev lag luam zoo tshaj plaws yog:
Tshawb xyuas koj cov pa tawm tam sim no thiab cov ntsiab lus txwv.
Xav txog cov cav: AFR, roj trims, backpressure kwv yees (los yog cov ntaub ntawv los ntawm gauges), EGT, thiab khob / ignition kho.
Yog tias ua tau, sib piv dyno rub lossis tsawg kawg ua ntej / tom qab datalogs.
Xyuas kom tseeb tias koj muaj (los yog npaj) lub suab sib haum nrog cov pa tawm.
Hauv qab kab
Yog lawm, X- yeeb nkab tuaj yeem nce horsepower-tab sis tsis yog ib txwm, thiab feem ntau qhov kev nce qib yog me me thiab nyob ntawm tag nrho cov pa hluav taws xob thiab kev kho.Yog tias cov khoom tso tawm (tshwj xeeb yog miv / mufflers) yog qhov txwv tsis pub, X- yeeb nkab ib leeg tuaj yeem hloov lub suab thiab kev tsav tsheb ntau dua li tsim lub zog dhia loj.
