What is the difference between v8 and v12 engine

Why V4 engines are so rare? SAAB 1. V4 is not impossible. Automotive technologies were definitely not so far advanced at that point and making a V4 was still possible. Not easy though. Lancia managed to make its engines decently smooth and powerful by engineering them with degree V angle. This meant that cylinder blocks are pretty close together.

In fact, so close that they worked with just one cylinder head, which cut down the manufacturing cost. And what nice engines those were — zippy, powerful and just singing. V4 engines have many advantages over inline 4 cylinders that are so common now.

First of all, they are shorter. Because cylinders are built into two banks situated besides one another, the entire engine is just two cylinders long. This means that it can be fitted into smaller engine bays or, even better, it can be mounted closer to the centre of the wheel base. This mid-engine layout really helps out the handling, making the V4 a great choice for sports cars. Being more compact, V4 is also more rigid.

It can become a more integral part of the chassis, providing some of that rigidity to the entire car. Can you name at least one? V4 is more expensive than I4. It is more difficult to engineer, it needs two inlet and exhaust manifolds, two valve trains and, most likely, two cylinder heads. And for what?

Rigidity is not really an issue in normal road cars and there is totally enough space in the engine bay for a puny 4-cylnder. Meanwhile V6, V8, V10 and even V12 engines are still being made. I wonder what the fuel consumption was for that little car? But, for him, it became tradition and mystic to have a V12 engine in the Ferrari cars. Of course they are smooth and sound exotic, but I'll not have another V12 automobile because I don't consider them practical.

The valve area is greater for 12 cylinders than 8 for the same capacity, no. The sound. A twelve makes a distinctive, lush, snarling, wailing sound. It adds a certain character and atmosphere to the driving experience. Luca di Monetzemelo said about Ferrari 'the music of the engine' - much like that. More cylinders fire every turn of the crank for a 12 than an 8. The 60 degree v12 is very smooth and balanced without balance shafts.

Even if the sound is muted for a luxury car, the smoothness can be a plus for using a V On a V12, the timings are interleaved more so that during the majority of operating times, three cylinders are at some point on their combustion BANG stroke. This leads to a smoother power cycle and smoother power delivery. It could be argued that a V16 configuration is arguably the "best" Vee formation engine but again that is personal opinion and V16's are very few and far between. V12 has smaller cylinders, smaller cylinders are easier to lubricate and cool than larger ones so they allow the engine to rev higher without getting into problems with lubrication and heat.

The Pistons in smaller cylinders don't move up and down as fast so they put less strain on the crank and connecting rods, require less lubrication, and are generally more efficient when producing power at higher revs. Perfect primary and secondary balance removes the need for balancing shafts or counterweights which helps the engine rev higher, rev more quickly, and produce more horsepower throughout the rev range.

More crankshaft rotation overlap allows reduces the need for a heavy flywheel on the crank which has the same benefits of not having counterweights or balancing shafts explained above. V12s are generally less compact than a V8 and quite a bit more complex as well as being slightly heavier.

Yusuf Kuntoro does not make a good argument. The engines in Nascar Sprint Cup cars are degree pushrod V8's, just like those that have powered many vehicles on American roads for more than 50 years. But today, the engine under Jimmie Johnson's hood is a custom-made hp cubic-inch engine.

This answer is simple, v12 engine burn air fuel mixture faster than v8 engine. Engineers get around that with increasing compression ratio, installing dual spark plug per cylinder, homogeneous fuel air mixture, etc. Sign up to join this community. The best answers are voted up and rise to the top.

Configuration and displacement are not the same.

I have a 1. A model builder has made a 12cc 0. I agree with you, V8s are the best. My understanding is that, all other things being equal, a V12 with a given displacement can rev higher than a V8 with the same displacement, probably due to the shorter stroke and less mass smaller pistons. It's also worth noting that Ferrari also has a cylinder line. This in turn can lead them to wonder whether a V8 or V12 will produce greater acceleration.

V8 and V12 engines are different kinds of engines that primarily differ on the number of cylinders they have, with the V8 incorporating 8 cylinders and the V12 utilizing 12 cylinders. While in general V12 engines are more powerful than V8 engines, there are many factors affecting acceleration, and which one results in faster acceleration comes down to individual engines and vehicle specifics, rather than engine categories as a whole.

A wide variety of factors affect the acceleration of a vehicle. A V8 is an engine with a V-shaped cylinder block and eight cylinders. There are different kinds of V8 engines, such as the flatplane V8 engine and crossplane V8 engine which is the most common V8 engine in cars. The crossplane engine has a secondary engine balance and operates more smoothly. The flatplane engine is lighter and can be revved more easily than a crossplane engine but it has a secondary engine imbalance which results in more vibration than the crossplane engine.

V8 engines are smaller than V12 engines, making them a more efficient choice when space in a vehicle is limited. V8 engines also offer better fuel economy over V12 engines as they consume less gas due to having fewer cylinders than a V
