Spray Behavior Comparison in Diesel Engine with Biodiesel as Fuel

Sprays are among the very main factors of mixture formation and combustion quality in almost every internal combustion engine. In present study spray penetration depth of various spray models are compared with the variation in injected pressure. The Mahua oil is taken as a biodiesel is the present study and Hiroyasu model can be used for predicting the performance of Mahua biodiesel. Hiroyasu model is found best model among all models studied for high injected pressure. The penetration depth difference of Hiroyasu and Arregle models increased sharply with lapse of time. Keywords: biodiesel; penetration depth; injection pressure; spray
