What is a 16 valve engine?

A 16 valve engine is an internal combustion engine that uses four valves per cylinder, as opposed to the more common two valves per cylinder. This design allows for improved airflow into and out of the cylinder, which can result in increased power and efficiency.

The use of four valves per cylinder also allows for better control of the combustion process, which can help to reduce emissions. For these reasons, 16 valve engines are often used in high-performance and environmentally friendly vehicles.

Here are some of the benefits of a 16 valve engine:

* Increased power and efficiency

* Better control of the combustion process

* Reduced emissions

* Improved fuel economy

However, 16 valve engines are also more complex and expensive to manufacture than two valve engines. As a result, they are not as common in low-cost vehicles.
