This product is made up of organic esters and a variety of high-efficiency additives. It is mainly used for the blending of diesel components of internal combustion engines such as diesel locomotives, ships, and power machinery. It can effectively improve the cetane number of diesel from general catalytic cracking, ethylene cracking, and waste oil regenerated. It can significantly improve the combustion performance of diesel and the performance of diesel engine cold start, exhaust emissions, combustion noise and so on. It can effectively improve the power output of the engine, reduce fuel consumption, reduce pollution, and bring considerable economic benefits.
