Negative Effects of too much Cetane

DFL has been formulated to increase the cetane level for optimum performance. These precautions can be avoided by using DFL.

 

Over-Advanced Combustion: Excessive cetane can cause the fuel to ignite too early in the combustion cycle. This can lead to increased pressure and temperature in the cylinder, potentially causing engine damage over time.

​

Reduced Power Output: If combustion occurs too early, it can lead to less efficient energy conversion, reducing the engine's power output.

​

Increased NOx Emissions: Early combustion can lead to higher peak temperatures in the cylinder, which can increase the formation of nitrogen oxides (Nox), a harmful pollutant.

​

Potential for Engine Damage: The increased pressure and temperature from over-advanced combustion can lead to increased wear and tear on engine components, potentially leading to premature engine failure.

​

Negative Fuel Economy: While higher cetane can improve combustion efficiency, excessively high cetane can lead to incomplete combustion, reducing fuel economy.

​

Practical Considerations: Optimal Range: There is an optimal cetane range for most diesel engines, typically between 40 and 55. Going significantly above this range can lead to diminishing returns and potential negative effects.

​

Manufacturer Recommendations: Always follow the diesel engine manufacturer's recommendations for fuel specifications, including cetane number.

Excessive cetane can lead to engine problems 
and reduced performance.  When adding DFL to diesel fuel at a ratio of 1:500 , the optimum cetane mixture is achieved.
