V6 how many valves

Your salesperson will likely mention things like 4 cylinder, V6 or V8 and often buyers are not certain of what this actually means.

Knowing a little bit more about the different engines could help to make your next purchase easier. Every vehicle has cylinders, and the engine size is generally denoted by how many cylinders a vehicle has.

A 4 cylinder has 4, a V6 has 6 and so on. Inside each cylinder is a piston, which moves up and down. Gasoline and air combine inside the cylinder and a spark creates combustion. The combustion then pushes the cylinder down, which creates motion that is transferred to the driveshaft, propelling the vehicle. This is why vehicle motors are referred to as internal combustion. Most cars are powered by a 4 or 6 cylinder engine, while most trucks have a 6 or 8 cylinder.

The more cylinders in an engine, the more combustion that occurs, creating more movement to turn the crankshaft and power to move the car. However, more cylinders also require more gasoline to make the combustion necessary to drive the car and thus are not as efficient.

This means that when you buy a 4 cylinder car, you are sacrificing power in order to increase efficiency. The 4 cylinder engine has to work harder to move the vehicle, hence why performance suffers.

Manufacturers such as GM have recognized this and are working to make 4 cylinder engines more enjoyable to drive. A major development target was to achieve high engine performance that fully matches to driver's expectations. To attain this objective, the engine incorporates a number of advanced technologies, such as a cross-flow cooling system, which utilizes a water gallery for the cylinder block and aluminum cylinder heads, ECCS Electronic Concentrated engine Control System , an individual cylinder knocking control system by cylinder pressure sensors, NVCS Nissan Valve Timing Control System.

With a compression ratio of , this new engine delivers high torque and high horsepower over the entire range of operating speed, and still maintains favorable fuel consumption.
