Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

An Otto engine operates with a compression ratio of 8.1 and a specific heat ratio of 1.4. Calculate the thermal efficiency. What improvements can be suggested for better efficiency?

💡 Hint: Focus on applying the efficiency formula correctly.

Challenge 2 Hard

If the temperature at the end of compression is 200°C, what would be the theoretical maximum work produced by the gas during the expansion phase assuming it behaves like an ideal gas?

💡 Hint: Check how to derive work done from expansion process.
