Roj twj tso kua mis tswj Circuit Court txoj cai
Muaj peb hom roj twj tso kua mis tswj Circuit Court: ECU-tswj roj twj tso kua mis tswj Circuit Court, hloov-tswj roj twj tso kua mis tswj Circuit Court, thiab roj twj tso kua mis tswj Circuit Court nrog ceev tswj.
1.ECU tswj roj twj tso kua mis tswj Circuit Court
(1) Thaum lub tshuab hluav taws xob qhib, tam sim no ntws los ntawm lub ntsiab relay coil, cov neeg raug kaw, thiab cov khoom siv hluav taws xob muab hluav taws xob rau EFI.
(2) Thaum lub cav pib, qhov pib ntaus ntawv (ST) lub davhlau ya nyob twg ntawm qhov hluav taws xob hloov hluav taws xob txuas nrog, thiab lub kauj L2 nyob rau hauv Circuit Court breaker relay yog energized, uas generates suction los kaw cov neeg ntawm lub Circuit Court breaker relay. Lub hwj huam mov yog muab rau lub twj tso kua mis roj, thiab cov roj twj tso kua mis tau muab tso rau hauv kev ua haujlwm.
(3) Thaum lub cav pib, lub sensor ceev yuav nkag rau lub cav ceev teeb liab Ne rau hauv ECU. Lub sijhawm no, lub transistor VT hauv ECU tau qhib, thiab lub kauj L1 hauv Circuit Court breaker relay yog lub zog, kom nws cov kev sib cuag tseem raug kaw, thiab lub twj tso kua mis roj tseem ua haujlwm.
(4) Thaum lub cav tsis ua haujlwm, VT raug txiav, cov kev sib txuas ntawm cov hluav taws xob txuas hluav taws xob raug txiav, cov khoom siv hluav taws xob ntawm cov roj twj tso kua mis cuam tshuam, thiab cov roj twj tso kua mis nres ua haujlwm.
2. Hloov-tswj roj twj tso kua mis tswj Circuit Court
(1) Qhib lub qhov hluav taws xob hloov hluav taws xob, cov kev sib txuas tseem ceeb raug kaw, thiab cov khoom siv hluav taws xob muab hluav taws xob rau EFI system.
(2) Thaum pib, qhov hluav taws xob hloov hluav taws xob txuas nrog lub davhlau ya nyob twg ST, lub Circuit Court breaker relay coil L2 yog energized, Circuit Court breaker relay hu raug kaw, thiab cov roj twj tso kua mis pib ua hauj lwm.
(3) Lub cav khiav, thiab cov cua nqus mus rau hauv lub cav ntws los ntawm lub ntsuas cua ntws. Lub ntsuas phaj nyob rau hauv cov pa ntsuas cua tig, tig lub roj twj tso kua mis hloov, thiab lub kauj L1 ntawm lub Circuit Court breaker relay pib energized.
3. Roj twj tso kua mis tswj Circuit Court nrog ceev tswj
(1) Thaum lub cav ua haujlwm ntawm qhov ceev lossis nruab nrab mus rau qhov me me, lub transistor hauv ECU tau qhib, thiab lub kauj ntawm cov roj twj tso kua mis tswj relay yog energized, ua rau kev sib cuag B kaw. Vim hais tias ntawm cov resistor muab tso rau hauv series nrog lub voj voog, cov roj twj tso kua mis ua haujlwm ntawm qhov qis qis.
(2) Thaum lub cav khiav ntawm kev kub ceev thiab hnyav, lub transistor hauv ECU raug txiav tawm thiab tiv tauj A raug kaw. Lub twj tso kua mis roj txuas ncaj qha mus rau lub zog hluav taws xob thiab khiav ntawm kev kub ceev.
