lomomike:I know say you go quote me with number and figures, I still remember when you no dey let us rest on top that QX45,hmmm now you don shift your knob to RX330. I get it, change is constant. |

chucky234: Is this an active beef mode? I still misses that truck Don't know why Infiniti put that truck to an end instead bringing a QX56. I won't mind going back to get a 2003 model for keeps as a monument |

Siena: Balance and smoothness While there are differences in smoothness, it is also greatly dependent upon the number of cylinders. Boxers are one of only three cylinder layouts that have a natural dynamic balance; the others being the straight-6 and the V12. These engines can run very smoothly and free of unbalanced forces with a four-stroke cycle and do not require a balance shaft or counterweights on the crankshaft to balance the weight of the reciprocating parts, which are required in other engine configurations. Note that this is generally true of boxer engines regardless of the number of cylinders (assumed to be even), but not true for all V or inline engines. However, in the case of boxer engines with fewer than six cylinders, unbalanced moments (a reciprocating torque also known as a "rocking couple" are unavoidable due to the "opposite" cylinders being slightly out of line with each other. It depends on the number of cylinders. 2 Cylinders: Boxer configuration is best (smoothest) but more expensive. Inline twins (or parallel twins) have the worst vibrations but cheapest to make. V-twins are slightly better than parallel twins but far from the best. 3 Cylinders: Inline triples are the best here minimal primary and secondary vibrations; also 'optimal' boxer and V arrangements are just not possible. Rotary (not Wankel, but radial or circular arrangement) is possible but take too much space, vastly more expensive, very heavy, just too many cons. I don't know if there is a working example of this configuration. This is true for radial engines of any number of cylinders - only aircrafts used to have radial rotary engines. 4 Cylinders: Boxers offer best smoothness (for all even number of cylinders) but more expensive. Inline 4's have some primary and secondary vibrations but can be eliminated using balancer shafts. V4's have vibrations and more expensive than inline 4's. 5 Cylinders: Similar to 3 cylinder engines in smoothness and cost aspect. Inline is best. 6 Cylinders: Inline is exactly equal to boxer for smoothness but boxers cost more while inline take more space (lengthwise). V6 cost less and can be built on the same line as V8's. There will be vibrations but can be eliminated using balancer shafts and they are compact. This is why V6 is so common. (Personally, I like BMWs' and Porsches' flat or inline 6's and I hate V6s because V6 only has financial advantages, no mechanical advantages. For an engineer like me, this matters). Inline configuration for over 6 cylinders becomes too big. 8 Cylinders: This is the only case where V is better when vibrations (very small magnitude) and cost are taken into account. Vibrations can be eliminated using balancer shafts. Inline 8 (or straight is too big. Boxer 8, just like all other boxers remains to be ideal (for all even number of cylinders). 10 Cylinders: Vibrations smaller than 8, boxers still ideal, Vs are very close to best. 12 Cylinders: This is where Boxer, Inline and V all have zero vibrations. V happens to be cheapest to make and compact as well. For these reasons, no one makes 12 cylinder engines in anything other than V.

Chuka, I agree with you as far as V6 engines go. They are manufactured "faulty", from an engineering perspective. The Boxer 6 still has a disadvantage compared to an inline 6 - oil consumption is high. Not as bad as a Rotary engine, but as far as piston engines, not the best. 12 cylinder engines are not only available in V configuration. The W12 is alive and well. |

nurey: I want to buy a v6 2003 mazda millenia from someone that has no issue with the car but just want to sell because she got a new corolla, i took a mechanic to help check it, he says the car is okay but he wont advice me to buy it because it has a v6 engine claims it is not good because it is my first car, that it consumes fuel bla bla. I really like the car but the man totally discourage me please i need candid advice on what to do? |

bolafma: I don't think a V6 engine consumes fuel but A 4cylinder of same car will have a better fuel economy than the 6 cylinder I won't advice you buy the 6 cylinder if much of your driving would be within city and less interstate cause then you are under utilizing the power of the V6 If your area is prone to traffic I won't advice a V6 either, you need a 2.0 4cylinder engine or something less so you can reduce cost of fueling the car. Above all If you are OK with 10L/100km that is 1500 for every 100km, then I did say you buy the car. The choice is yours |

nurey: Thanks for your time and input. Do you have any recommended mechanic for proper check? |
