Nano ic engines

  1. 1. GandhiInstituteofTechnology&Management SEMINAR ON NANO IC ENGINE Presentation By:- DEEPANSHU SHEKHAR Regd No:1101304075 Sem:8th

  4. 4.  NANO… one billionth of one and one third of micro ,to be precise 10^-9 m.  Nanotechnology is the manipulation of matter on an atomic and molecular scale.  It is the technology based upon the scaling down the existing technologies to next level of precision and miniaturization.  Nanotechnology in mechanical field is the internal combustion engine on a Nano scale, which I have chosen as My area of interest. INTRODUCTION
  5. 5. External combustion engine is the heat engine in which fuel combustion takes place external to cylinder. Due to this it is bulky and consumes a lot of place. Second revolutions of heat engines are ICE in which fuel combustion takes internally and consumes less place and became compact, cost effective. Of late third revolution is NANO Internal Combustion Engine. Revolutions In Engines
  6. 6.  From back plate to drive washer is less than 1 inch.  There are no exotic materials required. It has high precision ,cost effective, high speed (up to 40000rpm). IDEA OF SIZE OF NANO
  7. 7. MAIN COMPONENTS USED  CRANK CASE  BACK PLATE  CYLINDER AND HEAD  VENTURI AND NEEDLE VALVE ASSEMBLY  CONRODS AND CRANK SHAFTS  PISTON AND CONTRA PISTON
  8. 8. Construction of "Nano" - A 0.1cc Compression Ignition Engine  The Nano is a 0.1cc compression ignition engine - most frequently, if somewhat inaccurately, referred to as a "diesel".  It was designed by Richard Gordon and the plans were included as a supplement with the British Magazine Model Engineer in the early 1990's.
  9. 9. EXPLODED VIEW OF ENGINE
  10. 10. Like all model IC projects, there are a few special jigs and tools required to construct the Nano. The construction is extremely conventional - only the scale is unusual. The constructional cost is just USA$10 only in indian rupees it is approx RS. 500 .
  11. 11. NANO SPANNER  The odd looking thing is a special Nano-Spanner required to tighten the back plate.  It also fits the fuel nipple.
  12. 12. CUTTER  The cutter is used to form the exhaust ports in the cylinder
  13. 13. PISTON CROWN AND VENTURI  The crown of the piston is conical to assist transfer. The contra piston has a matching concave conical depression.
  14. 14. CRANKSHAFT COMPONENTS
  15. 15.  When it is fired, it run briefly, oscillating back and forth about TDC like over compressed diesels with small mass fly wheels are wont to do Running!.  But spring starters are the only way to start ultra small diesels - hand propping just won't work. WORKING OF NANO
  16. 16. Also, the fuel for mini diesels needs a lot of ether - as high as 50% by volume. With high ether fuel and a spring starter, the little Nano will burst into life. Richard Gordon claims it will turn 40,000 rpm. CONTINUED…..
  17. 17. APPLICATIONS  Nano ic engine has various applications ranging from race cars to space crafts.
  18. 18. CONTINUED…..  In race cars this IC Nano engine was used. The engine was fully fabricated, that is, no castings were employed.  It can be controlled in aero planes/satellites/space ships etc., The timing of inlet and exhaust valves.  According to NASA reports they are experimenting about the use of Nano engine in Nano & Pico satellites.
  19. 19. CONTINUED…..  In case of a mine tragedy where harmful gases are emitted ,these Nano ic engines can be employed as powerful blowers to blow out these gases is a time saving & the lives of trapped miners .  Agriculture pumps sets.  Every field of industry.
  20. 20. ADVANTAGES Adds great power to your engine. Boosts miles per gallon. Prolongs engine life. Cleans combustion chamber. Protects the environment.
  21. 21. With the application of Nano in every sphere of life the ‘big’ may not find its place in engineering dictionary in future. If we are to continue these trends we will have to develop a new manufacturing technology. It will let us inexpensively build Nano system with mole quantities that are molecular in both size and precision. NANO TECHNOLOGY WILL DO THIS…….. CONCLUSION
