What is a hexadecane number promoter?
Cetane number promoter is an additive used in diesel, which can improve the combustion performance and anti knock performance of diesel. In the process of diesel combustion, the combustion speed and combustion quality have a significant impact on the working efficiency and emission performance of the engine. The function of a cetane number promoter is to improve the combustion characteristics of diesel, increase the cetane number of diesel, thereby increasing the combustion speed and quality of diesel, and thereby improving the working efficiency of the engine and reducing emissions.
Cetane number: an important indicator of diesel performance
The cetane number is an important indicator of diesel fuel, which represents its anti knock performance under compression ignition conditions. The higher the cetane number, the better the anti knock performance of diesel and the higher the combustion quality. The cetane number of diesel fuel mainly depends on the content of aromatic and saturated hydrocarbons in its composition. The cetane number promoter increases the cetane number of diesel by changing the content of aromatic and saturated hydrocarbons in diesel.
The principle of action of hexadecane number promoter
The principle of action of hexadecane number promoter is to improve the combustion characteristics of diesel through the following aspects:
Improve ignition performance
Cetane number promoter can reduce the self ignition temperature of diesel, making it easier to ignite under compression ignition conditions. This can improve the ignition performance of diesel, reduce ignition delay time, and increase combustion speed.
Reduce detonation tendency
Cetane number promoter can reduce the detonation tendency of diesel fuel and make it burn more stably under compression ignition conditions. This can reduce the damage of detonation to the engine and improve its reliability and lifespan.
Improve mixture formation
Cetane number promoter can improve the mixing process of diesel and air, making the mixture more uniform and stable. This can improve the combustion quality of diesel, reduce the generation of incomplete combustion products, and reduce emissions.
Improve oxidation stability
Cetane number promoter can improve the oxidation stability of diesel and delay the oxidation reaction of diesel during storage and use. This can reduce the generation of sediment and maintain stable diesel quality.
In addition to the above principles of action, cetane number promoters can also improve the cetane number of diesel fuel by changing its molecular structure and chain length distribution. Different types of cetane number promoters have different mechanisms of action and application ranges, and suitable additives need to be selected according to specific situations when using them.
Application of Cetane Number Promoter in Diesel Fuel
As an additive for diesel, cetane number promoters play an important role in improving the combustion performance and anti knock performance of diesel. It can improve the ignition performance of diesel, reduce knock tendency, improve mixture formation, improve oxidation stability, etc., thereby improving engine efficiency and reducing emissions.
In addition to the above effects, hexadecane number promoters can also improve the lubrication and corrosion resistance of diesel fuel. Therefore, when selecting and using cetane number promoters, it is necessary to make reasonable choices based on the specific requirements and usage environment of diesel, and add them correctly according to the instructions for use.
Summary
In modern transportation, engines have a crucial impact on vehicle performance and environmental emissions. As an important diesel additive, hexadecane number promoter plays a crucial role in improving diesel performance. By improving the ignition performance of diesel, reducing knock tendency, improving mixture formation, and improving oxidation stability, the cetane number of diesel can be increased, thereby achieving the goals of reducing emissions, energy conservation, and environmental protection. Therefore, in modern transportation, the use of appropriate cetane number promoters has become a necessary choice.
