Carnot Cycle help - Engine temp reservoirs

Click For Summary
SUMMARY

The discussion centers on calculating the efficiency of a Carnot cycle in 4-stroke or 2-stroke motorcycle engines. The key temperatures required for this calculation are the hot reservoir temperature, which corresponds to the combustion temperature, and the cold reservoir temperature, which is the temperature at which exhaust gases exit the engine. Participants emphasize the importance of accurately determining these temperatures to effectively assess engine efficiency.

PREREQUISITES
  • Understanding of the Carnot cycle principles
  • Knowledge of engine thermodynamics
  • Familiarity with combustion temperatures in internal combustion engines
  • Basic concepts of heat transfer in engines
NEXT STEPS
  • Research the typical combustion temperatures for various motorcycle engines
  • Explore methods for measuring exhaust gas temperatures
  • Study the efficiency calculations specific to the Carnot cycle
  • Investigate the differences between 2-stroke and 4-stroke engine thermodynamics
USEFUL FOR

Engineers, automotive mechanics, and students studying thermodynamics who are interested in understanding engine efficiency and the application of the Carnot cycle in real-world engines.

Hi,

I need some help concerning the Carnot cycle [i've searched, but what i needed didn't come up]. I am trying to work out the efficiency of a 4 or 2 stroke motorcyle engine. [car engine, it doesn't matter really]. But I'm having some difficulty finding temperatures for the hot and cold reservoirs. I've searched the internet for a while...but still can''t come up with anything.

If anyone has any idea please help!

Thanks.

The hot reservoir temp is typically the combustion temperature, and the low temperature is the temperature at which the gas leaves the useful part of the engine.
