In order to improve fuel economy, by truly setting appropriate exhaust resistance, the intake efficiency is actually improved, the exhaust performance of the engine is established, or the balance between thickening and medium speed torque is improved to improve fuel economy, thereby increasing peak power and achieving acceleration. When customizing the muffler to exchange exhaust resistance and flow out to the fresh air exhaust valve (this situation is called overlap) in the low-speed range of the exhaust valve (this situation is called overlap), the intake stroke reaches the exhaust port opening, the charging efficiency decreases, and the torque decreases.
The vortex wheel reduces the exhaust resistance of the muffler, making it easy to discharge exhaust gas from the turbocharger or increase the desired boost pressure. However, the boost pressure of recent turbocharged cars is controlled by ECU, so these cars are also restricted. In addition, BMW car manufacturers in Europe also have a type of vehicle that adjusts exhaust resistance by opening or closing one side of the muffler outlet through a valve based on the engine load. Many cars switch their exhaust systems by changing the engine rotation and drive mode settings to open and close valves.
It has high speed range performance and suppresses exhaust noise during low-speed operation (can adapt well to noise regulation). The adjustment and handling of such mufflers are becoming a focus of environmental regulations for supercars.
In summary, whether in the short term or in the future, cars will not disappear. Is there a simpler alternative method to install more beautiful car exhaust pipes on cars?
