1.	In which type of muffler series of resonators are connected?(a) Baffle type(b) Wave cancellation type(c) Resonance type(d) Absorber typeI had been asked this question in a national level competition.This interesting question is from Exhaust System topic in section Exhaust System & Petrol Engine Fuel Supply System of Automotive Engine Design
Answer» RIGHT choice is (C) Resonance type Explanation: Resonance type muffler is ALSO called a Helmholtz type, after the person who originated the idea. It consists of several Helmholtz RESONATORS in series. Series of resonators eliminate the fundamental and higher harmonics of the engine noise.
