Ọrụ ihe mmetụta ịkụ aka ụgbọ ala
Isi ọrụ nke ihe mmetụta ịkụ aka ụgbọ ala bụ ịchọpụta ihe ịkụ aka nke injin ahụ, ma gbochie ịkụ aka site na ịhazigharị akụkụ mgbanye ọkụ, ka ọ wee chebe injin ahụ pụọ na mmebi. ;
Ihe mmetụta ịkụ aka na-atụgharị ụda igwe nke injin ahụ ka ọ bụrụ akara eletrik na-ebufe na ngalaba njikwa eletrọnịkị (ECU). ECU na-edozi akụkụ mgbanye ọkụ dị ka akara anatara si dị ka ịzenarị ndapụta na-aga n'ihu. Ihe mmetụta ịkụ aka na-ejikarị teknụzụ seramiiki piezoelectric. Mgbe injin ahụ na-ama jijiji, seramiiki na-agbakọ ma gbanwee iji mepụta mgbaàmà eletrik, nke a na-ebufe na ECU site na waya mkpuchi maka nhazi.
Ụkpụrụ na-arụ ọrụ nke ihe mmetụta ịkụ aka na-adabere na mmetụta piezoelectric, mgbe engine na-akụ aka, a na-agbanye ceramics piezoelectric n'ime ihe mmetụta, na-emepụta mgbaàmà eletrik. A na-ezigara akara ngosi ndị a na ECU, nke na-edozi akụkụ mgbanye ọkụ na-adabere na data echekwara iji gbochie ịkụ aka. Na mgbakwunye, ihe mmetụta ịkụ aka nwere ike ịhụ ọsọ na ọnọdụ nke injin ahụ, na-enye ọtụtụ ozi iji nyere aka kwalite arụmọrụ engine.
A na-etinyekarị ihe mmetụta ịkụ aka n'otu ebe dị na ngọngọ engine, dị ka n'etiti 2 na 3 cylinders nke igwe cylinder anọ ma ọ bụ n'etiti 1 na 2 cylinders na 3 ma ọ bụ 4 cylinders. Ọkwa nrịgo ya na-eme ka njide dị nro nke obere ịma jijiji na ịkụ aka.
Ọ bụrụ na ihe mmetụta ịkụ aka daa, ọ bụ ezie na ọ gaghị eme ka injin ahụ malite ịmalite, ọ ga-ebute nsogbu dị ka engine jitter, mfu ọkụ, mmebi akụ na ụba mmanụ ọkụ, na ọkụ ọkụ. Ya mere, ọrụ kwesịrị ekwesị nke ihe mmetụta ịkụ aka dị oké mkpa maka ịrụ ọrụ engine.
Sensọ ọkpọ ọkpọ ụgbọ ala bụ ngwaọrụ arụnyere na ngọngọ injin, nke a na-ejikarị achọpụta ịkụ aka nke injin ahụ. Enwere ọtụtụ ụdị ihe mmetụta ịkụ aka, nke kachasị n'ime ha gụnyere magnetostrictive na piezoelectric seramiiki.
Ụdị na nhazi nke ihe mmetụta ịkụ aka
Magnetostrictive : nwere isi magnetik, magnet na-adịgide adịgide na eriri induction. Mgbe injin ahụ na-ama jijiji, isi ihe ndọta ahụ na-agbanwe, na-ebute mgbanwe na ngbanwe magnetik na eriri induction, na-ebute ike electromotive.
seramiiki piezoelectric : Mgbe injin na-ama jijiji, seramiiki dị n'ime na-apịpịa ya iji mepụta mgbama ọkụ. N'ihi na mgbama ahụ adịghị ike, a na-ejikarị waya echedoro kechie eriri njikọ ahụ.
Resonance piezoelectric: arụnyere n'elu akụkụ nke engine ahụ, iji mmetụta piezoelectric mee ihe iji gbanwee vibration n'ibu n'ime ọkụ eletrik. Mgbe ụda ịkụ aka na-adaba na ugboro ugboro nke ihe mmetụta ahụ, ihe ngosi resonance ga-eme, na nnukwu voltaji mgbama ga-apụta na ECU, dịka nke ECU ga-edozi oge mgbanye iji zere ịkụ aka.
Otu ihe mmetụta ịkụ aka si arụ ọrụ
Ihe mmetụta ịkụ aka na-ahụ mkpọtụ na ụda nke injin ahụ wee gbanwee ha ka ọ bụrụ akara eletrik ezigara na ngalaba njikwa injin (ECU). ECU na-edozi akụkụ mgbanye mgbanaka dị ka mgbaama anatara si dị ka igbochi ihe mgbawa. Ụkpụrụ ọrụ kpọmkwem bụ ndị a:
Magnetostrictive : njin na-ama jijiji na-eme ka isi magnetik gbanwee, na-agbanwe mgbanwe magnetik na eriri induction, na-ebute ike electromotive.
Piezoelectric seramiiki : mgbe injin na-ama jijiji, a na-amanye seramiiki piezoelectric iji mepụta akara eletriki, ECU na-edozi oge mgbanye dị ka akara ngosi.
Ụdị resonance piezoelectric: mgbe ịkụ aka na-emegharị ugboro ugboro na-adaba na ugboro ugboro nke ihe mmetụta, ihe na-eme ka ọ pụta ìhè na voltaji mgbama mgbama na-arụpụta na ECU.
Ọrụ nke ihe mmetụta ịkụ aka na ụgbọ ala
Isi ọrụ nke ihe mmetụta ịkụ aka bụ iji tụọ ogo jitter nke injin ahụ. Mgbe injin ahụ na-emepụta ịkụ aka, a na-ebunye mgbaàmà eletrik na ECU, na ECU na-edozi akụkụ mgbanye ọkụ ahụ iji gbochie ịkụ aka ọzọ. Knock nwere ike imebi injin, yabụ ihe mmetụta ịkụ aka na-arụ ọrụ dị mkpa n'ichekwa injin ahụ.
