Indicate how well the fuel ignites
- Cetane in diesel is essential for engine efficiency, impacting combustion quality and performance. Cetane numbers indicate how well the fuel ignites; higher numbers mean smoother combustion. Ideal levels around 48-50 enhance engine operation. Higher cetane promotes faster ignition, improving power output and cold starts.

Jan 19, 2024 · Also known as a cetane number, cetane rating is the measurement of how much cetane is present in diesel fuel. It’s also used to indicate the combustion speed of diesel fuel. Some of the benefits of using high-cetane diesel include a quiet engine, quicker starting, and improved fuel efficiency.
Dec 11, 2019 · Cetane numbers are used to indicate the combustion speed of diesel fuel. Diesel fuels with higher cetane ratings have shorter ignition delays, providing more complete combustion and allowing engines to operate more effectively.
The cetane rating of a specific diesel mixture is based off of how much cetane—a clear, colourless hydrocarbon that ignites under high pressures—is in some fuel. Pure cetane represents the highest purity of diesel fuel possible, and thus has a cetane rating of 100.

Diesel users often equate the cetane rating in diesel fuel with the octane rating of gasoline. Conceptually, that's not a bad comparison. Both of them can give you a general indication of the combustion qualities of the fuel. The first fact to consider is that "cetane" and "octane" aren't chemicals that you add to the fuel. You may hear a mechanic ...
When a mechanic talks about adding cetane, this implies there are chemicals that you can add to diesel fuel that raise its cetane rating. That is true since a fuel's cetane rating is the average of the cetane ratings of everything that's in the fuel. How do these cetane improvers work? It's pretty simple and pretty legitimate (unlike those fuel mag...
If you hear a diesel fuel being described by its score on the Cetane Number test vs. a Cetane Index test, you should know there's a difference between the two. A fuel's Cetane Number reflects its performance in a standardized ASTM test involving a specific kind of engine. This is kind of the gold standard - a Cetane Number test is a fully involved ...
Both gas engines and diesel engines are designed to work optimally with fuel that has a specific octane or cetane rating. If the rating of the fuel is too low, you get performance issues in both kinds of engines. So if a diesel engine needs 45 cetane fuel, and you can only get 42 cetane, adding a cetane improverwill give you real benefit. But what ...
Cetane number (cetane rating) (CN) is an indicator of the combustion speed of diesel fuel and compression needed for ignition. It plays a similar role for diesel as octane rating does for gasoline.
Dec 24, 2022 · The cetane number or cetane rating is a measure of the ignition quality or knocking tendency of diesel fuel in a diesel engine. It is used to predict how easily the diesel fuel will ignite and burn when injected into the combustion chamber of a diesel engine.
