Exhaust systems 101?
Exhaust Systems 101?
I am interested in learning the basics of exhaust system design. Is the idea to vent the gasses as
quickly as possible? Is the the most efficient engine one which has no pipes or cats or mufflers at all?
What if an engine had the proper fuel/air input but was in a vacuum which would actually "pull" the
exhaust gasses out from the exhaust valves, would it be very much more efficient?
Since we need exhaust systems for safety and sound suppression what are we giving up as far as
engine efficiency? What does back pressure from the exhaust system do to HP and Torque? Are different
exhaust system designs just a trade-off between Hp/Torque at different RPM? I would really appreciate
answers from the knowledgeable people on this board. Any engineers out there?
