Egt (exhaust gas temperature) Egt (exhaust gas temperature) Presentation Transcript

  • EGT (EXHAUST GAS TEMPERATURE)
  • GROUP MEMBERS  JUNAID MUZAFFAR  HAMMAD MALIK
  • EGT  EGT stand for exhaust gas temperature. It measure the temperature of the exhaust gasses coming out of the nozzles. It is a tool used to monitor the engines health as well as setting the proper air-fuel ratio mixture.
  • INTRODUCTION  An EGT gauge measures the temperature as the exhaust leaves the cylinder.  EGT is a measure of the engine’s efficiency in producing its design level of thrust  The higher EGT is the more wear and deterioration affects the engine
  • EGT GUAGE: A must for safe flying  An EGT “pyrometer” is a non-contacting device that intercepts and measures thermal radiation, gauge monitors the temperature of the exhaust gases as they exist the combustion chamber.  An EGT can be used to maximize your engine performance, while monitoring its temperature for signs of problems.
  • How an EGT gauge works?  EGT gauges are self-powered and require no outside source of electrical energy other than for lighting.
  • Advantages of EGT gauges  The EGT instrument is a very useful tool with the following major advantages: 1) Saves fuel 2) Helps increase range 3) Aids in proper and precise fuel management 4) Aids in detection of engine problems 5) Helps to obtain peak engine performance at altitude 6) Reduces spark plug fouling 7) Adapts to most General Aviation piston engines.
  • Reason For Change In EGT 1. Air intake leak. 2. Air fuel mixture too lean 3. Air fuel mixture too rich 4. Changes in density altitude 5. Changes in relative humidity 6. Changes in air temperature 7. Pre-ignition or detonation 8. Fault spark plug or ignition system 9. Improper prop load 10. Poor quality or grade of fuel 11. Improper fuel air ratio, plugged main jet, failed needle jet, or clip
