Tsis xyoo thaum, diesel fuel injector tsev nyob rau hauv peb tsis yog lawm tau tawm hais tias cov kev pab yuav tau nrog txheej kev hu, thiab mus yim los yog yuav ua li cas qhov noj diesel. Yog hais tias tas los yog kev pab ib tug neeg ntawd, peb yuav tau nrog ib tug neeg pom qhia kev hu yuav kom paub nrog rau hauv kev cai, thiab muaj ntxiv ntsiab xav tau kev cai. Mus yim los yog kev pab no yog kawg, peb yuav hais tias peb tsis muaj txog qhov noj no yog lawm tau, thiab muaj lub sis sib luam los yog hauv tus txog. Yog hais tias yog kev pab no yog hauv, peb yuav muaj txog qhov noj no yog lawm tau, thiab muaj ntxiv ntsiab xav tau kev cai.
Tus pom injektor mek yog ib tug componeb nrog qhov system kev hu yuav muaj nws. Peb yuav muaj ib tug raug nrog yog hais tias: muaj kev hu nrog tus injektor. Tus injektor no yuav muaj kev hu thiab qhov nyem nrog rau hauv kev huav ua hauv qhov npaug ntawm kev cai yog ua hauv. Peb yuav muaj nws nrog yog hais tias muaj qhov nyem nrog rau hauv tub, thiab tus valves thiab springs nrog kev pab no. Nrog yog hais tias, tus componeb no yuav muaj peb tsis muaj kev hu nrog rau hauv kev cai, thiab muaj kev hu nrog rau hauv kev cai.
Cov camshaft yog cov thaum ntau qhoj tias li cas thiab qhua kom ua kev pab no. Yog li cas thiab qhua kom ua kev pab no, ib tug qhov xov xaiv thiab yuav tsum plaws rau hauv lawv thiab pump qhia ib tug inlet valve. Yog li inlet valve tsum plaws rau hauv, cov fuel nrog cov tank tau tshwm rau hauv pump. Simultaneously, ib tug qhov ntxawm nrog pump yog cov plunger tau tsum tsev xyoo. Cov step neeg yog ib tug qhov ntsi nrog pump operations.
Tsis camshaft mus rau hais tias lub plunger yuav los li cas pump. Nrog ntau tsis, yog li cas pressure noj ntawm fuel. Yog li cas spring nyob rau pump thiab mus rau plunger nrog hais tias lub plunger mus rau hais tias lub plunger mus rau hais tias lub plunger yuav komps fuel thiab mus rau hais tias pressure yuav txhob. Lub outlet valve yog li cas component noj ntawm pressure thiab mus rau fuel rau fuel injector.
Derun Mechanical kawm hais tias ib qab ib tug cov qhov ntawv common rail s rau hais tias lub engine yuav pom tshaj txog cov noj ntsiab. Nrog ntau tsis, ib tug fuel delivery thiab nyob rau hais tias noise thiab vibration. Yog li cas thiab hais tias li cas motor nrog hais tias noise thiab vibration.
Koj rau txhais, cov nyob qho mechanical injector pump yog ib tug xyoo thiab koj. Tab tom, cov nyob qho problems xwb yog low fuel pressure thiab dirty fuel filters. Yog li, los tsis nrhiav ntawm lawv lub engine mus kawg npawb, neeg yog hloov tawm fuel filter thiab koj mus tau noj thiab koj. Filter nrog dirty thiab mus kawg restriction ntawm cov fuel, yog li nrog thiab problems.
Los yog koj nyob qho ignition tsis paub muaj kev pab los ntawd engine, yog li ib tug xyoo thiab tab tom. Yog li, ib tug potential reason thiab noj yog low fuel pressure. Nws yog li yog ua li cas ua tawm cov fuel pressure regulator thiab mus tau test cov fuel pump ntawm issues. Yog li ntawv engine issues yog mus kawg damage, koj yog hloov tawm mus tau fix problems no los ntawd.
Derun muaj ntau dua 300 qhov tshuab tshuab uas yog qhov tseem ceeb tshaj plaws uas pab txhawb kev sib xyaw ntawm kev tsim cov lwm tshuab rau kev tsim cov lwm tshuab, kev tsim cov lwm tshuab thiab kev ua haujlwm thiab cov lwm tshuab uas siv rau kev ua haujlwm thiab kev ua haujlwm, thiab kev sib xyaw rau hauv qhov kev tsim thiab kev ua haujlwm. Derun muaj ntau dua 360 tus neeg ua haujlwm uas muaj 10 tus kws tshuab tshaj plaws thiab 20 tus neeg tswj kev ua haujlwm.
