Dear riders, have you ever wondered why it is the same car, some cars are particularly energetic when they run, and some cars feel so bad when they drive?In fact, the mystery lies in the engine's air intake system, which is the topic we are going to talk about today - variable valves. So, what the hell is this variable valve?And what's the benefit?Don't worry, let's find out.
We have to understand what a variable valve is. To put it simply, variable valves mean that the engine's valves can be freely changed in size during operation to suit the needs of different speeds and loads. It's like when we eat, we can adjust the size of our mouth as needed. Imagine if the engine also had a "mouth", then it could adjust the size of the "mouth" according to the size of the "meal". This is the basic principle of variable valves.
What are the benefits of variable valves?Let's take a closer look.
Variable valves optimize the combustion efficiency of the engine. At low speeds, by reducing the valve opening, the amount of air entering the engine can be reduced, allowing the fuel to burn more fully, thereby improving fuel economy. When the engine needs to work at high loads, the valve openings are enlarged to meet the greater intake demand and ensure sufficient power. This way, the engine stays in top working order, whether it's in the city or cruising on the highway.
The variable valves also improve the engine's emissions performance. By intelligently controlling the opening and closing time of the valve, the content of harmful substances in the exhaust gas can be effectively reduced, making the emission more environmentally friendly. This is a significant advantage for increasingly stringent emissions regulations.
Variable valves are also not a panacea. It requires more sophisticated design and manufacturing processes, as well as more advanced control systems for real-time adjustment. This means higher manufacturing costs and maintenance costs. However, in the long run, the investment is worth it. An engine with variable valves, like an all-rounder, can both achieve sprint** results and maintain endurance in long-distance running.
Having said all these benefits, let's talk about how to tell if your car has variable valve technology. In fact, it is very simple, read the manual of the vehicle or search the configuration table of the model on the Internet. In general, engines equipped with variable valve technology are clearly marked in the manual. If you can't find the information, you can also try to look up information online or consult a professional.
Let's summarize today's topic again. Variable valve technology is a technology that allows the engine to perform optimally in a wide range of operating conditions. It intelligently adjusts the opening and closing times of the valves, as well as the size of the valves, so that the engine can get the best intake effect at both low and high speeds. At the same time, it can also improve fuel economy, reduce the content of harmful substances emitted, and improve emission performance. Although its manufacturing costs and maintenance expenses are relatively high, the investment is worth it in the long run. Because an engine with variable valves, like an all-round athlete, can both achieve ** results in sprints and maintain endurance in long-distance running.
