A Study on the Features of NO Formation in the Cylinder of Biodiesel Engine

Abstract:

Abstract. A thermal mechanism of NO formation is developed to predict NO emission in the diesel engine and the explanation of more NOx emissions from the biodiesel engine exhaust is put forward. The start of ignition of biodiesel engine is early and so the trigger temperature of NO formation in cylinder is reached early. The mean temperature in cylinder will decrease in biodiesel engine. However, the concentration of oxygen at the combustion area is high due to the oxygenated property of biodiesel. Both of the two ways contribute to the more NOx emissions from biodiesel engine exhaust.
