Camless Rotating Cylinder Engine

• Project Presentation

2
Recognition of the problem

• Fossil fuels are at the verge of extinction.
• Its obvious we just cant stop using them at once.
• We have to use them wisely and efficiently so
  that it lasts longer and also creates less
  pollution.

3
What is the project ?

• It is the first major modification since the
  invention of the four stroke engine.
• This engine uses a rotating cylinder mechanism
  for the operation of valves.
• Use of this multifunctional cylinder decreases
  the parts count and weight of the engine also
  gets decreased thus increasing the overall
  performance of the engine.

4
Why automobile industry needs such change?

• Various drawbacks of poppet valves as follows-
• Reduced efficiency
• More number of parts to operate poppet valve
• Extra manufacturing, maintenance and handling
  cost

5
THE CHANGE

• The cavities on the sleeve are made to function
  as inlet and outlet valves for the CRC engine.

6

• A pinion attached to the crankshaft drives crown
  gear which is attached to the sleeve which
  rotates at half the crankshaft speed

7
How does it work?

• The four strokes of the CRC engine are as follows
• Suction
• Compression
• Power
• Exhaust

8
Suction

• Piston moves from the TDC to BDC with exhaust
  valve closed inlet valve open

9
Compression

• In this stroke both valves are closed the
  piston is moving from BDC to TDC.

10
Power

• Spark plug ignites the fuel during this stroke
  while both valves are closed, and the piston
  moves from TDC to BDC.

11
Exhaust

• Piston moves from BDC to TDC and the exhaust
  valve is opened.

12
BENEFITS

• Light Weight
• Better Fuel Efficiency
• Easy economic to manufacture maintenance
• Less number of moving parts
• No special machinery needed for manufacturing
• Energy conserving
• Better power output
• Multiple fuel capability
• Less Noisy
• Compact in size
• Dual Power Output
• Multi Utility Designs
• Less Vibration
• Portable engine size possible
• No valve bounce at high speed

13
Future Research Direction

• Decreasing friction between sleeve head by
  using floating seals
• Increasing turbulence by changing piston design
• Decreasing the problem of overheating at full
  load by direct cylinder oil cooling
• Decreasing oil consumption by revised
  cylinder/crankcase oil distribution
• Decreasing seal wear by using powder coating
  technology for seal material
• Use of self lubricating metals for rotting
  cylinder/sleeve to further reduce the frictional
  losses.
