Dhiraivha dhizaini
Iyo M54B25 injini yaive yakavakirwa pane aruminiyamu alloy cast cylinder block uye akakanda simbi silinda liners. Musoro wecylinder, wakagadzirwawo nealuminium, une cheni-inofambiswa neDOHC kaviri camshafts pamwe nemavharuvhu mana pacylinder, pahuwandu hwemavharuvhu makumi maviri nemana.
Vagadziri vechikamu chemagetsi vakafungawo kuishongedza neSiemens MS 43 control system uye Vanos dual variable valve timing yekupinza uye kupera kwecamshafts. Zita rakazara reiyi sisitimu ndiyo BMW variable valve timing system. Zvese izvi zvinowedzerwa neisiri-mechanicha yemagetsi throttle uye yakapetwa-kureba DISA yekutora manifold.
Panyaya yeinjini yeM54 B25, dhizaini isingaparadzirwe ine macoil ekupisa yakashandiswa zvakare. Chimwe nechimwe chazvo chakagadzirirwa zvakasiyana kune imwe neimwe cylinder uye thermostat, iyo inoshandiswa iyo inodzorwa nemagetsi.

Ichi chinhu chine macylinders, imwe neimwe inoratidzwa kune inotenderera inotonhorera. Iyo yakadzikama cast iron crankshaft inotenderera mumabhengi makuru anotsiviwa ane imba yakakamukana. Izvo zvinofanirwa kucherechedzwa kuti M54B25 ine minomwe mikuru mikuru.
Chimwe chinonyanya kukosha ndechekuti simbi yesimbi yekubatanidza tsvimbo inoshandisa inotsiviwa yakatsemuka mabhengi padivi re crankshaft, pamwe nemabhuranzi akasimba pane piston pini. Iwo mapistoni pachawo ndiwo matatu-mhete dhizaini ane maviri epamusoro compression mhete uye imwe-chidimbu yakaderera mhete inopukuta mafuta. Piston pins, kune rumwe rutivi, inobata nzvimbo yavo kuburikidza nekushandiswa kwecirclips.

Kune iyo M54B25 cylinder musoro, zvinhu zvekugadzira zvine sarudzo. Iyo aluminium alloy inopa yakanaka kutonhora inoshanda paramita. Mukuwedzera, inogadzirwa pahwaro hwekuyambuka-nyika dhizaini inopa mamwe masimba uye hupfumi. Iko kuvonga kwaari kuti mhepo inopinza inopinda mukamuri kubva kune rumwe rutivi uye inobuda kubva kune imwe.
Matanho ekugadzira akakosha akakonzerawo kudzikiswa kweruzha rweinjini. Izvi zvinoshanda kune valve clearance, iyo inodzorwa neanozvigadzirisa ega hydraulic lifters. Iyo inobvisawo kudiwa kwekugadziriswa kwevhavha nguva dzose.
Dhiraivha kushanda - chii chekutsvaga?
Panyaya yeinjini yeBMW M54B25, matambudziko akajairika ipombi yemvura isina kunaka uye isina kunaka thermostat. Vashandisi vanonongedzerawo kune yakakuvadzwa DISA vharafu uye yakatyoka VANOS zvisimbiso. Chivharo chevhavha uye chivharo chepombi yemafuta zvakare kazhinji chinotadza.
Iyo M54B25 injini yakakodzera kurumbidza here?
Munguva yekufamba kwayo, iyo M54B25 yakagamuchira wongororo yakanaka. Aigara achiisa pekutanga mune rondedzero yeakanakisa injini munyika yeWard magazine. Nekugadzirisa nguva dzose uye mhinduro yenguva kune zvinowanzoitika zvinokundikana, injini yeM54B25 ichashanda pasina kukanganisa kwezviuru zvemakiromita.
