Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A Dual Cycle engine operates with a compression ratio of 8 and a specific heat ratio (γ) of 1.4. Calculate its thermal efficiency. What happens to efficiency if the compression ratio is increased to 12?

💡 Hint: The formula relates compression ratio to thermal efficiency.

Challenge 2 Hard

Explain how adapting Dual Cycle engines might reduce emissions in urban settings compared to traditional engine cycles.

💡 Hint: Think about the environmental benefits of more efficient engines.
