Este f. bine stiut ca cele mai echilibrate motoare sunt cele al caror numar de cilindri este multiplu de 3. Dar daca esti geniu, toate certitudinile devin lesne utopii in prezenta ta.
*


Gresit conform Grunwald, Negurescu, si multi altii. Motorul in 3 cilindri este mult mai dezechilibrat decat cel in 2 sau 4.
Cazul celor 6 cilindrii in linie este un caz special, acolo echilibrarea nu se face cot cu cot, exista solutii mai eficiente de a scapa complet de armonica de ordin 1 (si daca e mecanism motor axat scapi si de armonicele de ordin par), si ramai cu armonica de ordin 3 mult diminuata ca intesnitate (si care si ea se echilibreaza perfect cu mecanism de echilibrare in carter cu 2 arbori)
Cel in 3 cilindri are o mare problema cu armonicile de ordin 1.

In principiu ai dreptate, dar nu vreau sa intru-n detalii gen arbore de balansare si armonici de ordin 2. Pe de alta parte, L6, V6 si V12 sunt cele mai echilibrate motoare si asta-i parerea unanima.

Bre Marty, multiplu de 3 deja inseamna multi cilindri (prea multi pentru un motor ieftin), daca nu ai bani decat de 2,3 sau 4 cilindri, parerea unanim acceptata (intre specialisti, nu intre chibitarii de la coltul strazii sau economisti)mai bine sa ai 4 decat 3. Si vorbeam de echilibrajul intrinsec al solutiei constructive, nu de solutii de a reduce vibratiile in habitaclu, ca daca te apuci sa pui arbori de echilibrare (si nu de "balansare" cum ai tradus cu engleza ta aia faimoasa de balta din originalul "balancer shaft") si suporti hidraulici activi la motorul de Matiz iese ceva mai scump decat un 2.0 16V. Totusi e bine ca ai postat la bula.
FYI, si motoarele cu 8 in linie sunt f bine echilibrate. Un V8 e mai bine echilibrat decat un V6, iar faptul ca motoarele cu 6 manetoane sunt bine echilibrate nu are nimic de a face cu echilibrajul motoarelor in 4 timpi cu 3 manetoane dispuse la 120 de grade.

A disadvantage of a straight-five over a straight-six engine is that a straight-five engine is not inherently balanced. A straight-five design has free moments (vibrations) of the first and second order, while a straight-six has zero free moments. This means that no additional balance shafts are needed in a straight-six. By comparison an inline-four engine has no free moments of the first or second order, but it does have a large free force of the second order which contributes to the vibration found in unbalanced straight-four designs


Citeste tu inainte sa dai altora exemple. Poate afli si e ee o armonica de ordinul 1 si 2 si cat de naspa e asta pentru motorul cu piston. Eu nu am inceput discutia tehnica, ci Marty care si-a imaginat ca stie despre ce vorbeste si s-a gandit sa-mi dea peste nas.

Fiecare citeste ce-i place...

QUOTE
A five-cylinder engine gets a power stroke every 144 degrees (720° ś 5 = 144°). Since each power stroke lasts 180 degrees, this means that a power stroke is always in effect. Because of uneven levels of torque during the expansion strokes divided among the five cylinders, there is increased secondary-order vibrations. At higher engine speeds, there is an uneven third-order vibration from the crankshaft which occurs every 144 degrees. Because the power strokes have some overlap, a five-cylinder engine may run more smoothly than a non-overlapping four-cylinder engine, but only at limited mid-range speeds where second and third-order vibrations are lower.

Every cylinder added beyond five increases the overlap of firing strokes and makes for less primary order vibration. An inline-six gets a power stroke every 120 degrees. So there is more overlap (180° - 120° = 60°) than in a five-cylinder engine (180° - 144° = 36°). However, this increase in smoothness of a six-cylinder engine over a five-cylinder engine is not as pronounced as that of a five-cylinder engine over a four-cylinder engine. The inline-five loses less power to friction as compared to an inline-six. It also uses fewer parts, and it is physically shorter, so it requires less room in the engine bay, allowing for transverse mounting.


Si daca e sa continuam discutia, o sa ajungem la motoare in stea sau Wankel.

Ia si citeste de aici despre armonici de gradul 1 si 2, vezi ce scrie in linkul pe care l-ai pus despre vibratiile la 5 in linie si vezi ca sunt varza la capitolul echilibrare fata de un straight-six sau V8/V12.
