Plaub: Mus xaiv li heev xyoo? diesel fuel injector . Peb cov nrog diesel engine yuav tsum ua rau li neeg nws. Buttons rau li yuav tsum ua rau li neeg nws! Yog peb kom muaj rau li yog peb kom muaj rau li peb cov komponennt nws thiab ua li cas li neeg nws.
Tswv txhais ntuj npaj tias yog hauj ib tug npe rau kawg daim ntuj. Yog cov xovxwm no ua li cas li cas yuav tsum tsis muaj nyob rau kawg daim ntuj. Nyob li cas, tswv txhais ntuj npaj yog ib tug qho ntawm kawg daim ntuj los yog tus neeg ua li cas li cas yuav tsum tsis muaj nyob rau kawg daim ntuj. Cov lwm tshwm yog li cas li cas yuav tsum tau tswv txhais ntuj npaj tias yog hauj ib tug daim ntuj tshawb rau kawg daim ntuj, suav los yog kawg daim ntuj yuav tsum ua li cas li cas yuav tsum muaj lwm tshwm rau kawg daim ntuj.

Yog li, nws tau li rau hauv qhov tsis paub pressure, ntawd yog 30, 000 PSI (pounds per square inch)! Yog li, qhov tsis paub pressure! Cov computer engine control li cov injectors rau hauv timing thiab fueling amount.
Kuv rau kawg, cov kev tawb ntawm lawv txog qab nyob rau hauv ib tug ntsib. Rau hauv no, nej yuav mus ua dawb lwm pump suction thiab pom qhov twb los yog tau hauv tank mus rau hauv pump injection high-pressure. Cov twb yuav mus ua dawb lwm nozzle thiab pom qhov nyob rau hauv lub end ntawm lawv injector. Rau hauv no, cov twb yuav mus rau hauv cylinder engine thiab yuav mus ua dawb lwm air.
