Hi, can anyone point me in the direction of some good information relating to the design of automotive exhausts? In particular design of headers and calculations for noise attenuation.
Thanks!
Thanks!
brewnog said:Sure. Winterbone et al published a fantastic paper on the theory of manifold design, which should be a really good step in the right direction. Also Blair's book, "design and simulation of four stroke engines" has some excellent stuff on runner design.
The purpose of designing automotive exhaust headers is to improve the performance of the engine by increasing the efficiency of exhaust gas flow. This leads to better fuel economy, increased horsepower, and reduced emissions.
Exhaust headers are designed using computer-aided design (CAD) software and are typically made from stainless steel or ceramic materials. The design process involves considering factors such as the engine's size, cylinder layout, and desired performance goals.
Noise attenuation is an important factor in designing automotive exhaust headers as it helps to reduce the loud and unpleasant sounds produced by the engine. This is achieved by using different materials and designs to absorb and dissipate the sound waves.
Exhaust headers have a significant impact on the overall exhaust system as they are responsible for collecting the exhaust gases from each cylinder and routing them to the exhaust pipe. A well-designed exhaust header can improve the performance and sound of the entire exhaust system.
Yes, aftermarket exhaust headers can be used to improve the performance of a vehicle. These headers are designed to have larger primary tubes and better flow characteristics, which can increase horsepower and torque. However, it is important to ensure that the aftermarket headers are compatible with the specific vehicle's engine and exhaust system.
