Ukuvulwa kwe-valve yokunciphisa ukucindezela kuhlukaniswe ngezimo ezimbili: ukuvulwa okusebenzayo kanye

ukuvulwa kokwenziwayo.

Ukuvula okusebenzayo

Lapho ithola ulwazi lwamaphutha kwezinye izingxenye ezihlobene, iyunithi yokulawula i-elekthronikhi yenjini (ECU) izosebenzisa isu lokuvikela futhi iyalele ivalvu ekhawulela ingcindezi ukuthi ivuleke (ngisho noma umfutho wesitimela ungekho phezulu kakhulu), ngaleyo ndlela igweme ukwehluleka okukhulu kwenjini. Iluphi ulwazi lwengxenye lwephutha oluzobangela i-ECU ukuthi isebenzise isu lokuvikela?

1. Isignali yenzwa yokucindezela kaloliwe

Lapho inzwa yokucindezela kukaloliwe ithumela isignali yokucindezela kukaloliwe ngaphezu komkhawulo ku-ECU, kungakhathaliseki ukuthi iphezulu kakhulu noma iphansi kakhulu, izobangela i-ECU ukuthi isebenzise isu lokuvikela futhi ivule i-valve ekhawulela ingcindezi. Kunezizathu eziningi zokuthi inzwa yokucindezela kwethrekhi ibike umlayezo wephutha. Ingqikithi ingcindezi yokungena kawoyela engavamile noma ingcindezi yokubuyisela uwoyela, njengokungatholakali kukawoyela okwanele emugqeni kawoyela onengcindezi ephansi, ukuguga kwepompo enengcindezi ephezulu, ukuvaleka kahle kwe-valve ekhawulela ingcindezi, kanye nevolumu yokubuyisela uwoyela ngokweqile kusuka kumjovo. . Ulayini kawoyela uvalekile, njll.

2. Isignali yokuhluleka kwevalvu yemitha yamafutha

Ukuze kuthuthukiswe ukusebenza kahle, iphampu enengcindezi ephezulu yohlelo lukaloliwe oluvamile ifakwe iyunithi yemitha yokulawula ubuningi bamafutha, okuyi-valve yokulinganisa uphethiloli. Ilawula umfutho kawoyela esitimeleni somfutho ophezulu ngokulawula inani lamafutha angena empompini yomfutho ophezulu. I-ECU ilawula iyunithi yokulinganisa ngokushintsha umjikelezo wemisebenzi ngaphakathi kweyunithi yokulinganisa ngamasignali we-pulse. Uma i-valve yokulinganisa ihluleka, kusho ukuthi i-ECU ayikwazi ukuqedela ukulawula okunembile kokucindezela kwesitimela. Ngakho-ke, uma ithola ulwazi lwephutha oluhlobene ne-valve yokulinganisa, njengesekhethi esifushane, iphutha lesekhethi evulekile, noma iphutha lokushisa elingavamile, i-ECU izosebenzisa isu lokuvikela ukukhawulela i-valve yokucindezela nayo izovuleka.

3. I-sensor power supply module 3 isignali yephutha

I-sensor power supply module 3 inikeza amandla kagesi angu-5V wezinzwa eziningi, kuhlanganise nezinzwa zokucindezela kukaloliwe. Uma imojula yesi-3 yokunikezwa kwamandla enzwa yehluleka, kusho ukuthi zonke izinzwa ezibhekene nazo zingase zisebenze ngendlela engavamile. Ngakho-ke, uma i-ECU ithola ulwazi olunephutha oluhlobene ne-sensor power supply module 3, izokwenza isu lokuvikela futhi i-valve yokunciphisa ingcindezi izovuleka.

4. Amaphutha ahlobene ne-ECU

Njengomkhuzi oyinhloko wesistimu yezitimela ezivamile, imiphumela yokwehluleka kwe-ECU ingacatshangwa. Ngakho-ke, lapho uhlelo luthola ulwazi lwephutha oluhlobene ne-ECU, luzophinda lusebenzise isu lokuvikela.

Ukuvula okwenziwayo

Izizathu ezivamile zokuvula kancane zihlanganisa: i-valve yokulinganisa uphethiloli noma ukwehluleka kwe-valve yokukhulula, ukwehluleka kwepompo yokucindezela okukhulu, ukulimala kwenzwa yokucindezela komzila wesitimela okuholela ekuphumeni kokucindezela kukaloliwe, ukuvaleka kwamapayipi kawoyela abuyayo, njll.
