16Vs

16Vs refers to a specific engine configuration found in internal combustion engines. The "16V" designation indicates that the engine has a total of sixteen valves. In a typical four-stroke engine, valves control the flow of air and fuel into the combustion chamber and the exhaust gases out. These valves are usually divided into intake valves, which let the air-fuel mixture in, and exhaust valves, which let the burnt gases out.

The sixteen valves are generally distributed across the cylinders. For an inline four-cylinder engine, a common configuration is four valves per cylinder, resulting in eight intake valves and eight exhaust valves in total. This layout, known as a DOHC (Double Overhead Camshaft) system, allows for two camshafts, one for the intake valves and one for the exhaust valves. This setup can lead to improved engine performance compared to older designs with fewer valves per cylinder, such as 8V (two valves per cylinder).

Engines with 16 valves often benefit from better airflow, allowing for more efficient combustion and potentially higher power output and improved fuel economy. The increased number of valves enables a larger total surface area for both intake and exhaust flow, which can optimize the engine's breathing and performance across a wider range of engine speeds. This configuration is widely used in modern passenger cars, performance vehicles, and motorcycles.
