Why do some diesel engines run smoothly while others knock and produce smoke?
The answer lies in one critical property of fuel — cetane number.
Main Description:
In this video, we break down the science behind cetane and how it affects diesel engine performance. You’ll learn:
What cetane number really means
Why ignition delay matters
The difference between high and low cetane fuel
How diesel knock occurs
How refineries control cetane through processing and blending
We also take you inside the combustion chamber to visualize what actually happens when fuel is injected — and why timing is everything.
Whether you're a student, engineer, or just curious about how engines work, this video simplifies complex refinery and combustion concepts into clear visuals.
