Question:
Thermodynamic cycle on which the petrol engine works is
Thermodynamic cycle on which the petrol engine works is
Show Hint
Otto = Petrol (Spark). Diesel = Diesel (Compression). It’s the "engine" name to remember.
Updated On: May 5, 2026
- Joule cycle
- Otto cycle
- Rankine cycle
- Stirling cycle
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Heat engines are modeled using theoretical thermodynamic cycles that describe the pressure-volume changes.
Step 2: Meaning
Spark-ignition (petrol) engines follow a cycle consisting of two adiabatic and two isochoric (constant volume) processes.
Step 3: Analysis
This cycle was popularized by Nikolaus Otto. In this cycle, combustion (heat addition) is assumed to happen instantly while the piston is at the top of its stroke, meaning the volume doesn't change during the explosion.
Step 4: Conclusion
The petrol engine operates on the Otto cycle.
Final Answer: (B)
