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

(3) The lubriCAT-parts-partsion performance of biodiesel is better than that of diesel: it can reduce the friction loss of the engine oil supply system and 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 does not belong to dangerous fuel and has obvious advantages in transportation, storage and use.

(5) Excellent combustion performance: Biodiesel has a higher cetane number than diesel, so the fuel has better combustion resistance when used, so higher compression ratio engines can be used to improve its thermal efficiency. Although the calorific value of biodiesel is lower than that of diesel, the oxygen contained in biodiesel can promote the combustion of fuel and improve the thermal efficiency of the engine, which can make up for the loss of power to a certain extent.

(6) Renewable: biodiesel is a kind of renewable energy, and its resources will not be exhausted like oil and coal.

(7) Economical: the system using biodiesel has less investment, and there is no need to change the original diesel engine, refueling equipment, storage equipment and maintenance equipment.

(8) Reconcilability: biodiesel can be used in combination with petrochemical diesel in a certain proportion, which can reduce fuel consumption, improve power and reduce exhaust pollution.

(9) Degradability: biodiesel has good biodegradability and is easy to be decomposed and used by microorganisms in the environment. The excellent performance of biodiesel makes the exhaust emission index of the engine using biodiesel not only meet the current Euro II standard, but also meet the more stringent Euro III emission standard to be promulgated and implemented in Europe. In addition, the carbon dioxide emitted by biodiesel combustion is much lower than that absorbed by the plant during its growth, thus improving the global warming, a major environmental problem harmful to human beings caused by carbon dioxide emissions. So biodiesel is a real green diesel.
