  1. 1. SUPERCHARGER Group 2. KHAIRIL AZREEN BIN KHOLID MUHAMMAD AMIN BIN YAZID AMIR YUSUF BIN HAZIMI MOHAMED HAIRI BIN ABDUL SHUKUR MUHAMMAD NURAZMAN BIN MOHAMED EDIN 01DAD10F2046 01DAD10F2056 01DAD10F2058 01DAD10D2060 01DAD10F2062
  2. 2. WHAT IS SUPERCHARGER? A supercharger is an air compressor used for forced induction of an internal combustion engine.  The greater mass flow-rate provides more oxygen to support combustion than would be available in a naturally aspirated engine, which allows more fuel to be burned and more work to be done per cycle, increasing the power output of the engine. 

  4. 4.  Centrifugal Type
  5. 5.  Screw Type
  6. 6. CONSTRUCTION OF SUPERCHARGER
  7. 7. OPERATION OF SUPERCHARGER
  8. 8. Roots Type  The Roots type supercharger or Roots blower is a positive displacement lobe pump which operates by pumping fluids with a pair of meshing lobes not unlike a set of stretched gears. Fluid is trapped in pockets surrounding the lobes and carried from the intake side to the exhaust 
  9. 9.   Centrifugal Type The centrifugal-type supercharger is an enginedriven compressor used to increase the power output of an internal-combustion engine by increasing the amount of available oxygen by compressing air that is entering the engine. This type of supercharger is practically identical in operation to a turbocharger, with the exception that instead of exhaust gases driving the compressor via a turbine, the compressor is driven from the crankshaft by a belt, gear or chain drive.
  10. 10.    Screw Type Lysholm is also called screw type supercharger. The supercharger consists of 2 screws, one with male threads and another with female threads. They closely mesh together. When they rotate, air is captured between the screws and the housing while being pushed from the inlet towards the outlet. Moreover, the space gets smaller and smaller as it moves forward, so Lysholm performs internal compression and enables higher boost pressure than Roots type supercharger.

  18. 18. ADVANTAGES AND DISADVANTAGES OF SUPERCHARGED
  19. 19. ADVANTAGES OF SUPERCHARGER Advantages of a Supercharger  1). Increased power  2). No lag – Consistent power delivery  3).Generally better throttle response  4). No Special Procedures or extra maintenance  5). Centrifugal Superchargers are more efficient at higher RPM  6). Roots & Twin Screw Superchargers are efficient at low RPM  7). Easier to tune  8). Easier to install than turbochargers 
  20. 20. DISADVANTAGES OF SUPERCHARGER 1). Consumes a lot of power from the engine (therefore not very efficient)  2). Increases the strain on the engine  3). Increases the strain on the running gear  4). Expensive  5).Noise 
