The cetane number is one of the basic indicators of diesel fuel quality; this parameter shows the combustion speed of diesel fuel and it is inversely proportional to the time between the moment of ignition of fuel and the increase of pressure in the combustion chamber. The higher the cetane number, the shorter the above time and the more smoothly the engine will run. The cetane number also affects the engine’s cold start performance, exhaust emissions and noise during engine operation.
