Lub tsheb mus rau Dongfeng Cummins nkag siab sensor 4921322

Manifold tsis txaus siab sensor (MAP).

Nws txuas cov kev nqus cov tub rog, thiab nrog lub cav sib txawv ntawm cov kev hloov pauv ntawm cov khoom siv hluav taws xob rau ECU los kho cov roj kev txhaj tshuaj thiab qhov tsis loj.

Hauv EFI cav, lub siab ntsuas lub zog yog siv los txheeb xyuas cov pa nqus pa, uas yog hom tshuaj tua hluav taws xob (nrawm dua hom). Cov pa tawm ntawm cov pa tawm tsam cov tshuaj tiv thaiv cov pa hluav taws xob tsis ncaj qha hloov ncaj qha raws li cov huab cua ntws tawm. Nyob rau tib lub sijhawm, nws kuj cuam tshuam los ntawm ntau yam, yog li muaj ntau qhov sib txawv ntawm kev kuaj pom thiab kev saib xyuas ntawm cov pa roj ntws sensor, thiab kev ua txhaum los ntawm nws kuj muaj nws qhov tshwj xeeb.

Qhov kev nkag siab lub zog sensor kuaj pom lub meej ntawm cov kev ua kom muaj peev xwm ua tiav tom qab lub throttle. Nws kuaj pom cov kev hloov ntawm lub zog tsis zoo nyob rau hauv lub manifold raws li lub cav nrawm thiab thauj nws mus rau hauv lub teeb liab voltage thiab xa mus rau lub cav tswj chav tsev (ECU). EPU tswj hwm cov roj roj kev txhaj tshuaj yooj yim dua li ntawm cov paib hluav taws xob.

Lub ntsiab cai ntawm kev ua haujlwm

Muaj ntau ntau yam kev nkag siab cov sensors, xws li viistor thiab capacitor. Vim tias qhov zoo ntawm cov sijhawm rov qab teb, qhov muaj qhov loj me thiab hloov tau yooj yim thiab cov varistor tau siv dav hauv kev txhaj tshuaj-D-hom.

Tus qauv sab hauv

Lub siab sensor siv lub siab nti rau kev ntsuas siab, thiab lub siab chip siab, thiab lub siab chip instalremed ib tug choj nplej ntawm lub siab silicon uas tuaj yeem raug txiav tawm los ntawm siab. The pressure chip is the core of the pressure sensor, and all the major manufacturers of pressure sensors have their own pressure chips, some of which are directly produced by the sensor manufacturers, some of which are special-purpose chips (ASC) produced by outsourcing, and the other is to directly buy general-purpose chips from professional chip manufacturers. Feem ntau, cov chips ncaj qha tsim los ntawm sensor tuam ntxhab lossis customized Asc chips tsuas yog siv hauv lawv cov khoom. Cov chips no tau ua ke heev, thiab lub siab nti, amplifier Circuital, Ecc tiv thaiv Circuit Court thiab ROM rau calibrating nkhaus yog txhua yam sib xyaw ua ke rau ib nti. Tag nrho cov nti yog ib qho nti, thiab lub nti tau txuas nrog tus lej PIN ntawm cov txuas los ntawm kev ua.
