Pump-kamwene: kupatsanura uye kugadzira

Gore negore kwokudiwa kuti Diesel injini maererano nzira dzakadai simba, ikoroji uye upfumi chete kukura. Uye chete paumbwe imwe zvinobata moto musanganiswa akakwana anogona kugutsa izvi zvinodiwa. Naizvozvo, yose mafuta jekiseni hurongwa kuti ishande zvakanaka, ichipa miniti sprayed pasi kumusoro kumanikidzwa.

hurongwa kwakadaro, iyo rinobatanidza mune imwe chikwata mafuta injector uye pombi, mumwe pombi-atomizer. Saizvozvowo, mukuru kumanikidza pombi, pombi-injector raanozvibaya imwe mari nezvakavhenganiswa panguva yakakodzera. Nokuti kuti mumwe nomumwe sepombi injini pane chimwe chikwata injector, zvakadaro hurongwa hapana mafuta jekiseni pombi.

Midziyo mokugezera zvinosanganisira humburumbira musoro anoda Diesel chikwata injector. Kuti ndivaise simba pamusoro camshaft 4 ane cam that. The simba pamusoro plungers chikwata injectors iri chinopfuudzwa kubudikidza rocker. Nokuda chinokosha Profile of chikwata injector rocker cam that kutyaira kutanga nehasha rinobuda, uye ipapo anowira zvinyoronyoro.

Panguva yakadururwa pane yakapinza richisimuka kubva rocker ruoko, kuti plunger rikazvisundira nokukurumidza zvikuru pasi. Naizvozvo, pane cheBP. Kana rocker ruoko anotanga kuwa zvishoma nezvishoma, sezvo plunger anotanga sipidhi uye yunifomu kufamba kumusoro. kuvakwa kwakadaro kunoita chinotsva kupinda mukuru kumanikidzwa kamuri zvakanaka, pasina paumbwe mhepo matema. Nguva nguva uye jekiseni kuzvidzora solenoid vharafu kudzora chikwata injector. Nokuti chinangwa ichi, kuburikidza electronic kudzora chikwata yaipiwa pamwe voltage. Kunyange zvarakasiya vaduku chirimwa parameters kuitika pfapfaidzo mafuta kuparadzwa, injini anotanga "ruzha."

Diesel injector pombi rinogona mhando nhatu: piezoelectric, remagetsi, electrohydraulic. With solenoid vharafu kamwene yakaiswa sezvo peturu uye Diesel michini, uye ane nyore urongwa: yacho kamwene uye solenoid vharuvhu ane tsono pfapfaidzo. The Electro-injector chete yakaiswa pamusoro Diesel michini, izvo zvingangoita kuti ushande hurongwa Caumont Ryle. Piezoelectric vaiona zvemberi Diesel injini. Akadaro chikwata injector kunouya kune 4 nguva nokukurumidza kupfuura solenoid, uye mishonga jekiseni mafuta pamwe kunonyanyisa zvakarurama.

Yokugadzirisa injectors zvinofanira kuitwa kana paine zvinotevera zviratidzo: wakawedzera mafuta kuparadzwa zvinokosha, kukundikana kana iwe pavanoshandisa pamusoro gasi chitiviri, mafuta leakage kana popping ari chiutsi mugadziriro. Singles motokari kumhanya kusagadzikana: tsono tachometer iri kuramba "kusvetuka" pasina chikonzero. Kuongorora mokugezera uye kugadzira kwavo rinoitwa musi chaiwo mikoko, saka zvakaoma kuagadzira vakazvimirira: achiisira kumanikidzwa chete 10% pamusoro vaizviti chinokonzera Kukundikana injini. Uye kunyange kana basa iri mafuta hurongwa asingadi kupa chikonzero chokunetseka, injector Diagnostics - Maitikiro acho inokurudzirwa pashure ose 60 000-70 000? Km kubva run mota.
