The advantages of biodiesel
Biodiesel, also known as fuel methyl ester, is a new type of fuel made from vegetable oil or animal oil processing. Its performance is similar to that of 0# diesel. When using biodiesel, there is no need to improve the structure of existing diesel engines. The characteristics are as follows:
1. Biodiesel is low in sulphur, but emissions of sulphur dioxide and sulfides are reduced by 30%.
2. Better lubrication performance can reduce the wear rate of fuel injection pump, engine cylinder and connecting rod
3. Better starting performance of low temperature reverse motor
4. Biodiesel has a high flash point, is not a dangerous product, is not volatile, and the biodegradation rate is as high as 98%
5. The cetane value of biodiesel is high, and its combustion performance is higher than that of petrochemical diesel
It's a renewable resource
7. High petrochemical efficiency ratio
