Ukugcoba okulungisekayo
Ukusebenza kahle kwephampu kawoyela, ekhuphuka ngesivinini, kusho ukuthi uhlelo lokuthambisa alukwazi ukusebenzisa wonke uwoyela. Umfutho kawoyela kufanele ulinganiselwe.
Kuhlelo lwe-lubrication yakudala, i-valve yokulawula imishini isetshenziselwa le njongo, evula lapho izinga elithile lokucindezela lidlula. Ukungalungi kwalesi sixazululo ukuthi, naphezu kokucindezela okuncishisiwe, ipompo yamafutha iyaqhubeka nokusebenza ngokugcwele. Ngaphezu kwalokho, ukupompa amafutha nge-valve yokulawula kudinga ukukhululwa kwamandla, aguqulwa abe ukushisa okungadingekile.
Isixazululo sezinkinga eziphakama ngale ndlela yokulawula ingcindezi ohlelweni lokugcoba ipompo elingakwazi ukudala amazinga amabili okucindezela ahlukene. Eyokuqala, ephansi, ibusa isistimu kuze kufike kusivinini esithile, ngale kwalokho iphampu ishintshela ebangeni eliphezulu. Ngakho-ke, isistimu yokugcoba ithola inani eliqondile lamafutha adingekayo ukuze kugcinwe ukucindezela kwamafutha okulungile kuwo.
Ukucindezela kwamafutha kulawulwa ngokushintsha umthamo wepompo. Iqukethe i-axial displacement yamagiya epompo aqondiswe ngaphandle. Uma zibhekene ncamashi, ukusebenza kahle kwepompo kuphakeme kakhulu. Ukususwa kwe-axial kwamasondo kubangela ukwehla kokusebenza kahle kwepompo, ngoba inani lamafutha ampontshwa lincike kusayizi wendawo yokusebenza yezingxenye zokukhwelana zamasondo.
Enjinini elungiswe ngale ndlela, iphampu yamafutha isebenzisa inzwa yesibili eyengeziwe ebhalisa izinga eliphansi lokucindezela, elihlola kanyekanye ukuthi kukhona yini ukucindezela ohlelweni lokuthambisa. Isibonelo salezi zinqola ezinamandla izinguqulo ezithuthukisiwe ze-1,8L kanye ne-2,0L TFSI ezine-cylinder ezine-timing chain drive.
