Investigation of Performance Analysis and Emission Characteristics of Biodiesel

The emission characteristics of carbon dioxide, carbon monoxide, nitric oxide hydrocarbons and improve engine performance was found to be higher than pure diesel. Biodiesel is to choose a diesel that is safer, produces less harmful combustion emissions are easily. B20 is the most common biodiesel blend in the world. B20 is popular because it represents a balance of cost, emissions, materials compatibility, reduced engine wear through the increased lubricity and ability to act as a solvent. However, biodiesel has a higher Cloud Point (CP), Pour Point (PP), and Cold Filter Plugging Point (CFPP) than diesel oil. The increase in these cold flow properties is related to the gelling of biodiesel at higher temperatures than diesel fuel oil. The use of biodiesel blends, thus, pose potential operational problems in cold external environment. Biodiesel degrades due to oxidation, contact with water, and activity. The oxidation of biodiesel can produce various acids or polymers which, if in high enough concentration, can cause fuel system corrosion and deposits which in turn can lead to filter clogging and fuel system malfunctions. In addition, advanced direct injection engines may lose significant power when poor quality biodiesel blends are used. An effective performance diesel fuel additive can help guard against such problems. This work includes analysis with B20 blends of the some oils and use of additives in biodiesel.
