Should the Exhaust Valve Be Closed When Driving on the Highway?

It is best not to close it. The function of the exhaust valve is to control the exhaust sound and the size of the exhaust back pressure. More relevant information is as follows: 1. Introduction: The exhaust valve is an essential auxiliary component in pipeline systems, widely used at the highest points, elbows, or areas where air may be trapped in pipelines. It helps to remove gas from the pipeline to ensure smooth operation. Without this valve, the pipeline may experience air resistance at any time, preventing it from achieving the designed water capacity. Additionally, power outages during pipeline operation can cause vibrations or even ruptures. 2. Working Principle: During the exhaust state, the float, due to gravity, pulls one end of the lever downward, causing the lever to tilt. This creates a gap between the lever and the exhaust hole, allowing air to escape through this gap. As the air is expelled, the water level rises, and the buoyancy of the water causes the float to rise. The sealing end of the lever gradually presses against the exhaust hole until it is completely blocked.
When driving on the highway, I always close the exhaust valve because the engine is already running steadily at high speed, and there's no need for the exhaust sound to assist acceleration. After closing it, the noise inside the car, especially the resonance, is significantly reduced, making long-distance driving more comfortable and less fatiguing. With less noise, it's easier to listen to music or navigation, improving driving focus and safety. I've driven different types of cars, and high-performance cars are louder with the valve open at high speeds, but closing it makes them quieter and more suitable for daily use. Remember to regularly check the valve position to ensure it doesn't get stuck. Closing the valve causes less wear on the system, making maintenance easier.
Every time I hit the highway, I just have to keep the exhaust valve open! The exhaust roar at high speeds is exhilarating, and the car feels more powerful during acceleration—pure driving pleasure. Some might argue that closing it makes for a quieter ride or better fuel efficiency, but highways are already fuel-efficient conditions, and the thrill of that sound is irreplaceable. My car is modified, so with the valve open, the exhaust flows freely, making occasional high-speed bursts effortless. The louder sound also helps alert nearby vehicles, adding a safety perk. Sure, comfort takes a slight hit, and it’s better to close it for low-speed city driving—but on the highway, keeping that valve open is where the real fun is.
