What does 16v engine mean?

16v engine refers to an engine with 16 valves. For engines of the same displacement, more valves generally mean better performance. To improve intake and exhaust efficiency, multi-valve technology is now widely used. It is common to have 4 valves per cylinder, so a 4-cylinder engine would have a total of 16 valves, hence the designation 16V. Below is some extended information about valves: 1. The function of valves is to specifically input air into the engine and expel the exhaust gases after combustion. Structurally, valves are divided into intake valves and exhaust valves. The intake valve's role is to draw air into the engine to mix with fuel for combustion, while the exhaust valve's role is to expel the burned gases and dissipate heat. 2. Valves are responsible for inputting fuel into the engine and expelling exhaust gases. Traditional engines have only one intake valve and one exhaust valve per cylinder. This design is relatively simple, cost-effective, easy to maintain, and performs well at low speeds. However, the drawback is that it is difficult to increase power, especially at high speeds where the air charging efficiency is low and performance is weaker.
I've driven quite a few cars, some of which were equipped with 16v engines. This marking is quite common on engine covers, essentially indicating that the engine has 16 valves. Think about it: traditional engines, like 8v ones, might only have 8 valves, but a 16v engine is typically a 4-cylinder setup with 4 valves per cylinder—two for intake and two for exhaust. This means more efficient intake and exhaust, akin to adding a multi-lane highway to the car, allowing air to flow more smoothly and gasoline to burn more completely. As a result, the car feels more powerful and accelerates more responsively. I've used cars with 16v engines and found them noticeably more fuel-efficient than older models, especially on highways, where fuel consumption can be about a liter less per 100 kilometers. However, the increased precision in design also means slightly higher repair costs, requiring regular maintenance checks on the valve system. Overall, 16v is a standard configuration in modern mainstream cars aimed at achieving a balance. When you see this marking on a new car, you can generally trust its performance in terms of power and fuel economy.
