Diferente motor e90 facelift 318i vs. 320i

Recommended Posts

Ma uitam la specificatii si am vazut ca motoarele de pe cele doua modele e90 respectiv 318i si 320i sunt identice dar ofera o putere si un cuplu diferit... Doream sa stiu daca e vorba doar de niste modificari la computerul masinii sau sunt implicate si alte schimbari la motor... Deci, daca aveti idei just shoot...

Nu va ingramaditi colegi!Ati ramas in pana de "pareri"? Sau sunteti buni doar la "atacuri de hiene" cum nu va place un cuvant sau o expresie dintr-un topic? Eu stiu acest lucru deja.Nici macar moderatorii?Revoltator.

 

Dormi in continuare prietene si nu mai comenta aiurea !

 

 

Pentru crisjohn la diesel stiu ca exista modificari si la motor de la 318 la 320, eu cred ca si la benzina se intampla acelasi lucru, in proportie de 90 % sunt sigur de lucrul asta ! Ah acum am vazut ca tu de fapt vorbesti de 320i cu motorul nou 2007 ala de 173 cp care se pune pe 320si, iar ala e motor cu VANOS pe cand 318i nu prea este ! Sper ca iti dai seama cate diferente exista !

Era mai bine dacĂŁ vedeai 10-15 posturi farĂŁ vreo bazĂŁ realĂŁ?

 

Nu cantitatea conteazĂŁ, ci calitatea.

Totusi codul motorului pentru 318i si pentru 320i este acelasi N43B20... ma indoiesc ca nu ar fi Valvetronic si Vanos amandoua si apropos au injectie directa generatia a 2-a... si apropos e acelasi motor de pe seria 5 e60... 320 = N43B20 (4 cyl, 2.0 liter, Gas Direct Injection) si acleasi lucru este si pe 318... inca studiez pentru ca motorul acesta N43B20 este foarte nou si nu sunt multe informatii pe net despre el...

 

Uite aici detalierea (http://en.wikipedia.org/wiki/List_of_BMW_engines si aici http://bmwdriver.org/?page_id=116):

 

2007– — N43 2 L new petrol and diesel engines, boreĂstroke 84Ă90 mm, 1,995 cc, 4 valves per cylinder, source: BMW Group (March 23, 2007). BMW EfficientDynamics in Detail. Press release. http://www.worldcarfans.com/news.cfm/newsI...amics-in-detail.

 

* Petrol, 200 bar direct fuel injection with piezo-injectors, continuously adjustable intake and outlet camshaft, 135 kg

o 105 kW (143 PS), 190 Nm (140 ftˇlbf) in the BMW 118i

o 125 kW (170 PS) at 6,700 rpm, 7000 rpm max, 210 Nm (155 ftˇlbf) at 2,250 rpm, 12:1 compression ratio. Note that this straight-4 engine achieves the same amount of power and torque as in the straight-6 M54B22 engine.

 

si uite aici specificatiile pentru motor:

 

Engine information for N43 - 4 cylinder inline DOHC 16v Direct Injection naturally aspirated petrol engine

 

Built from: 2007-now

Displacement range: 1995cm3

Number of cylinders/valves: 4cylinders / 16valves

Fuel: petrol

4 cylinder petrol engine:

- N43 - 2.0L DOHC-16v/L4 + High Precision Injection

 

 

http://www.bmwheaven.com/component/option,.../mtype,N43#e194

 

 

diferenta este la parametrii de dupa codul motorului si asta trebuie sa descopar ce insemana N43 B20 O0 (4 / 16 - 1995cc - petrol - 125kW / 170HP (@ 6700rpm) - 210Nm (@ 4250rpm)) si la 318/118 N43 B20 U0 (4 / 16 - 1995cc - petrol - 105kW / 143HP (@ 6000rpm) - 190Nm (@ 4250rpm))

 

adica diferenta este de la O0 la 320 si 120 i la U0 la 318 si 118 i... acum studiez asta <_<

 

M-Number Management Displacement Cyl/Valves Arrangement Stroke/Bore Compression Weight Fuel Power Torque Redline

1 N43 B16 O0 MSD 81.2 1599cc 4 / 16 inline 4 75.7mm / 82mm 12:1 petrol 90kW / 122HP (@ 6000rpm) 160Nm (@ 4250rpm)

2 N43 B20 O0 MSD81.2 1995cc 4 / 16 inline 4 90mm / 84mm 12:1 petrol 125kW / 170HP (@ 6700rpm) 210Nm (@ 4250rpm)

3 N43 B20 U0 MSD81.2 1995cc 4 / 16 inline 4 90mm / 84mm 12:1 petrol 105kW / 143HP (@ 6000rpm) 190Nm (@ 4250rpm)

 

 

si culmea este ca au acelasi management bazat pe MSD81.2 si sunt VANOS cu double precision injection... deci, unde e diferenta?

Sa inteleg ca vrei sa iti iei E90 cu una dintre cele 2 motorizari si nu stii pe care sa o alegi ? Ti-am zis diferente sunt si la motor si chiar daca nu ar fi gandeste-te ca 318 este sugrumat din soft in primu rand, are harta gandita altfel, pentru un consum mai mic si performante mai modeste.

acum pe criza asta bmw o sa puna numai soft de 320 si o sa vanda la pret de 318, ca sa nu ii afecteze asa tare si pe ei!!

Are deja un 318i E90 LCI.

 

 

exact... doream sa vad care e diferenta ca sa inteleg cum sa fac sa ajung la motorul de pe 320 :) e aceiasi idee ca si cea cu M43 care a fost facut in 3-4 variante cu diferite puteri doar ca acolo se cam stia de unde e diferenta... la motoarele actuale daca ma uit strict la datele de pe internet referitoare la modelul de injectie si datele fizice ale motorului (inclusiv compresia) pot spune ca sunt total identice si nu inteleg de unde vine diferenta in afara de soft... tocmai de aceea am provocat aceasta discutie pentru ca cineva mai in tema sa ma puna la curent si pe mine <_<
