The cetane number is an important indicator for measuring the spontaneous combustion performance of diesel, which directly affects key performance such as cold start, exhaust emissions, and combustion noise of diesel engines. The cetane number of straight run diesel is generally above 50, which can meet the combustion requirements of high-speed diesel engines. However, with the increasing demand for diesel, the proportion of catalytic diesel and coking diesel has increased, and these diesel fuels have lower cetane numbers (usually between 30-40) and poorer combustion performance.

Cetane number improver has strong sensitivity, and its effect is closely related to the properties of oil and processing technology. The cetane number of diesel oil can be increased by 3-6 points by adding 0.5%-2% cetane number improtant. This product is easily soluble in diesel oil, and can be added to diesel oil proportionally when used.
