Advantages of biodiesel:

(1) It has excellent environmental protection characteristics: biodiesel and petrochemical diesel have low sulfur content, and sulfur dioxide and sulfide emissions can be greatly reduced after use. The exhaust emission index can meet the European II and III emission standards.

(2) Low-temperature starting performance: Compared with petrochemical diesel, biodiesel has good engine low-temperature starting performance, and the cold filter point reaches -20°C.

(3) The lubrication performance of biodiesel is better than that of diesel: it can reduce the friction loss of the engine fuel supply system and the cylinder liner, increase the service life of the engine, and indirectly reduce the cost of the engine.

(4) It has good safety performance: the flash point of biodiesel is higher than that of petrochemical diesel. It is not a dangerous fuel and has obvious advantages in transportation, storage and use.

(5) Excellent combustion performance: The cetane number of biodiesel is higher than that of diesel, so the fuel has better combustion and anti-riot performance when in use, so a higher compression ratio engine can be used to improve its thermal efficiency.
