Answer 1

Hey dude


Typical values. Generally, diesel engines operate well with a CN from 48 to 50. Fuels with lower cetane number have longer ignition delays, requiring more time for the fuel combustion process to be completed. Hence, higher speed diesel engines operate more effectively with higher cetane number fuels.

Answer 2

The cetane number of diesel fuel is a measure of the ignition quality of diesel fuel.

Explanation:

• Cetane number determines the ignition quality of diesel fuel.
• It is similar to the octane number which rates the combustion quality of a fuel.
• Cetane number measures the delay in the time of ignition of fuel.
• If the cetane number is higher, then the ignition of the fuel is quicker.
• It ensures that non-ignited fuel in the combustion chamber is less and the complete combustion of fuel takes place.
• Quick ignition and complete combustion of fuel give high efficiency of fuel.
• Thus, harmful emissions are reduced.
