A V8 engine is a V engine with eight cylinders mounted on the crankcase in two banks of four cylinders, in most cases set at a right angle to each other but sometimes at a narrower angle, with all eight pistons driving a common crankshaft. It is basically a two straight-4 engine sharing a common crankshaft. On the other hand this simple configuration, with a single-plane crankshaft, has the same secondary dynamic imbalance problems as two straight-4s, resulting in annoying vibrations in large engine displacements. Therefor, since the 1920s most V8s have used the somewhat more complex cross plane crankshaft with heavy counterweights to eliminate the vibrations. This lead to an engine which is smoother than a V6, while being considerably less expensive than a V12 engine. Racing V8s continue to use the single plane crankshaft because it allows faster acceleration, more efficient exhaust system designs, and a "throatier" acoustic quality.
Also, if you want to rent a car with a V8 in Romania you hire it from a profesional rent-a-car agency.

Weird Fact

THE MOST COMPLEX PAPER MODEL IN THE WORLD

A ?V8-Engine? that has a semi-realistic exterior and interior detail. It is made entirely from paper (except a motor, a battery holder, a few plastic tubes and electrical wires). No paint applied. It looks pure and elegant. Various shadows created by different light sources make the appearance more 3D. Many movable parts include a compound crankshaft, a rapid cooling fan, 8 rods, 8 pistons and a complex compound gearbox etc. It is handcrafted with ruler, white glue and X-acto knife. It took approximately one year to design and construct. Each part is precisely made (for instance, the five separate bearings need accurately alignment). The reinforced structure applied in both inside the body of engine and the stand (most of them can not be seen). The reinforced structures make it very rigid and keep the pieces in the accurate positions.

The paper engine is made by Yee which is a Canadian Artist. His company Yee's Job is located in Montreal. He designs & handcrafts all kind of paper craft.
