Discussion Overview

The discussion revolves around the feasibility of modifying an engine to compress air inside the cylinder at bottom dead center (BDC) by introducing a plate to separate the crankcase and cylinder block. The aim is to pressurize air similarly to turbochargers and superchargers, and participants explore the implications of this modification on engine efficiency and output energy.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant proposes modifying the engine by adding a plate at BDC to compress air introduced after the expansion stroke, suggesting this could function like a turbo or supercharger.
  • Another participant agrees that the idea could be possible but warns that it may lower the output energy or efficiency of the machine, suggesting that using exhaust for charging might be a better approach.
  • A participant expresses gratitude for the positive feedback received and indicates that it helps them move forward with their project.
  • One participant seeks clarification on whether the reduction in output energy would be significant or minimal.
  • A different participant believes that the reduction in output energy would be less than expected and suggests a more complex design that could utilize compressed air from both sides of the piston for greater output.
  • Another participant acknowledges a delay in their response, indicating ongoing engagement in the discussion.

Areas of Agreement / Disagreement

Participants express differing views on the impact of the proposed modification on output energy and efficiency, indicating that multiple competing perspectives remain without a clear consensus.

Contextual Notes

The discussion includes assumptions about the design complexity and potential efficiency trade-offs, which are not fully resolved. The implications of using compressed air from both sides of the piston are also not fully explored.

i need a clarification regarding my project work..

can we compress the air inside the cylinder at bottom dead center by modifing the engine by introducing a plate at BDC to separate crank case and cylinder block. piston bottom compresses the air which we introduced into cylinder just after expansion stroke using plate as obstacle and sends pressurized air to intake manifold.,

actually my idea i like compressing air to pressurize just like turbo and super chargers do.

does this idea is possible.
 
Engineering news on Phys.org
Yes it can be possible but this will lower the output energy or efficiency of the machine. Better to use the exhaust for chargers
 
Thank u Jmex..,
Thanks for your positive reply it really help me a lot to move further.
Thanks a lot
 
one clarification jmex,
does reduction of output energy will be higher or lower?

What I believe from my experience will be less reduction in output but think about introducing another charge from the bottom portion. Design will be bit complicated but output will be great. This way you can use compressed air from both side as well as power from both side by every power stroke.
 
Sorry for late reply.
