Iyini indima yenzwa ye-camshaft yezimoto
I-Camshaft isikhundla senzwa idlala indima ebalulekile enjini yemoto, umsebenzi oyinhloko ukuqoqa isiginali ye-camshaft isikhundla futhi ukufaka kwiyunithi yokulawula nge-elekthronikhi (ECU) ukuze kunqunywe isikhathi sokulahla kanye nesikhathi sokudonswa kwamafutha. Ngokuthola isikhundla sokujikeleza kwe-camshaft, inzwa inquma isikhathi sokuvula nokuvala se-valve, ngaleyo ndlela ifinyelele ekuphathweni okuqondile kwenjini.
Umgomo osebenzayo we-Camshaft isikhundla se-Sensor ususelwa ekungenisweni kwe-electromagnetic noma ubuchwepheshe be-Photoelectric wokungenisa. Lapho i-camshaft ijikeleza, inzwa ibona i-bump noma i-notch ku-camshaft futhi ikhiqize isibonakaliso sikagesi esihambisanayo. Ngemuva kokuthola lezi zibonakaliso, i-ECU inquma isikhathi sokulahla kanye nesikhathi sokuphonsa uphethiloli ngokubala nokucutshungulwa, ukuze kufinyelelwe ukulawula okunembile kwenjini.
Ukunemba kanye nokwethenjwa kwezinzwa ze-Camshaft isikhundla kubalulekile ekusebenzeni kwenjini kanye nomnotho wezomnotho. Uma inzwa yehluleka, kungaholela ekulahleni okungalungile, kwehlise ukondla uphethiloli, futhi kungenzeka ngisho nenjini engasebenzi kahle. Ngakho-ke, ukuhlolwa okujwayelekile nokunakekelwa kwe-Camshaft isikhundla se-Sensor kubaluleke kakhulu.
Isenzo se-Camshaft iyingxenye ebalulekile yemoto, ikakhulukazi esetshenziselwa ukuthola isikhundla se-camshaft nesivinini, ukuqinisekisa ukusebenza okujwayelekile kwenjini. I-Camshaft Sensor, eyaziwa nangokuthi i-Camshaft Photon Sensor (CPS) noma i-Cylindern Sensor (CIS), umsebenzi wayo oyisisekelo ukuqoqa amasiginali wesikhundla we-valve camshaft. Lezi zimpawu zondla kuyunithi lokulawula ngogesi (ECU). Kulezi zimpawu, i-ECU iyakwazi ukukhomba i-Compression TDC ye-Cylinder 1 ngokulawula okulandelanayo kokulawulwa kwamafutha, ukulawulwa kwesikhathi sokulahla kanye nokulawulwa kwe-deflagration.
Ukwakheka kanye nomgomo wokusebenza
Kunezinhlobo eziningi zezinzwa zesikhundla se-camshaft, kufaka phakathi i-PhotoElectric kanye nokungeniswa kwamabuzi. I-PhotoElectric Sensor yakhiwa ikakhulukazi idiski yesiginali, i-Signal Generator kanye nomsabalalisi, futhi ikhiqiza isiginali nge-diode ekhipha ukukhanya kanye nokuhamba ngezithombe. Uhlobo lokungeniswa kazibuthe lusebenzisa umphumela wehholo noma umgomo wokungeniswa kazibuthe ukukhiqiza amasiginali, okuvame ukuhlukaniswa ngohlobo lwehholo nohlobo lwe-magnetoelectric.
Isikhundla sokufaka
I-Camshaft isikhundla se-Sensor ivame ukufakwa emaphethelweni angaphambili wesembozo se-camshaft, maqondana nokuphela kwangaphambili kokudla nokuphekela amandla e-camshaft. Lo mklamo uqinisekisa ukuthi inzwa ingaqoqa ngokunembile isiginali ye-camshaft isikhundla.
Ukusebenza Okubi kanye nomthelela
Uma inzwa ye-camshaft yehluleka, izimpawu ezijwayelekile zifaka ubunzima bokuqala imoto, ubunzima bokubonisa amandla noma ukuqina lapho kushisa, kwanda ukusetshenziswa kwamafutha, amandla anganele. Lezi zimpawu zibangelwa ukungakwazi kwe-ECU ukulawula kahle ukujova uphethiloli kanye nesikhathi sokulahla isikhathi.
