Exhaust system

  1. 1. IC ENGINE EXHAUST SYSTEM Submitted by Prakash chand kumawat B.E. Final yr. College of technology and engineering, Udaipur.
  2. 2. INTRODUCTION Exhaust gas or flue gases is emitted as a result of the combustion of fuels such as petrol, diesel or fuel oil  A car's exhaust system is responsible for transporting the burned exhaust, or combustion gases, from its engine and out through the tail pipe. 
  3. 3. Importance of exhaust system The exhaust system has three major functions: 1. To channel out the waste products of combustion out of the engine. 2. To reduce the noise generated by the engine. 3. To clean up the emissions that are harmful to the environment.
  4. 4. Pollutants from Exhaust  CO — carbon monoxide. CO2 — carbon dioxide. NOx — nitrogen oxide HC — hydrocarbons.  Other pollutants such as C6H6 — Benzene and its derivatives and SO2 — sulphur dioxide are also present.
  5. 5. Exhaust system Components of Exhaust System: 1. Exhaust Manifold 2. Muffler 3. Catalytic converter 4. The Tail Pipe
  6. 6. Exhaust Manifold  Hot exhaust gas along with sound waves generated at the end of exhaust stroke is sent to the exhaust manifold through the exhaust valve. which is extremely hot, further burns any fuel that was inadequately burned by the engine . Sound waves and exhaust gas pass from exhaust manifold to catalytic converter through a pipe.
  7. 7. Exhaust Manifold
  8. 8. Catalytic Converter A catalytic converter is a device that uses a catalyst to  convert harmful compounds in exhaust into harmless  compounds. Inside the catalytic converter there  consists two ceremics blocks with micro ducts  consisting of platnium and rohadium in one block  while platinium and pladium in other block, act as  catalysts
  9. 9. Catalytic Converter
  10. 10. Reactions in the catalytic converter
  11. 11. Muffler The exhaust gas now becomes less toxic but consists of sound waves generated by the engine. To cancel the noise of these sound waves, the gas is made to flow through the muffler . Muffler consists of chambers of different sizes.
  12. 12. Exhaust Pipes:   The exhaust pipes, which can be metal or aluminium, are responsible for transporting the burned exhaust gases from the engine and the exhaust manifold and funnelling them towards the car's tailpipe.
