Cetane number improver is also called diesel cetane number improver
Cetane number of diesel is the main index of anti-knock property of diesel oil.
The surface phenomenon of diesel engine knock is similar to that of gasoline engine, but the cause of knock is different.
Although both detonation originated from the spontaneous combustion of fuel, the cause of diesel engine detonation is just the opposite of gasoline engine, because diesel is not easy to spontaneous combustion, the beginning of spontaneous combustion, fuel accumulation in the cylinder caused by too much.
Therefore, the cetane number of diesel also represents the naturalness of diesel.
The cetane number is 100 n-cetane. If the knock resistance of some oil is the same as that of standard fuel containing 52% n-cetane, the cetane number of the oil is 52..
The use of high diesel fuel, diesel engine combustion uniformity, high thermal power, fuel saving.
Generally speaking, high speed diesel engines with a speed of 1000 RPM use light diesel with a cetane value of 45-50, while medium and low speed diesel engines with a speed of less than 1000 RPM can use heavy diesel with a cetane value of 35-49.
