Why are there differences in SMD variation of gasoline port injector and diesel injector when placed both the injectors vertically?

04 April 2014 1 6K Report

SMD (sauter mean diameter) for gasoline port injector ( 3-hole injector) increases along the vertical axis at some point and for diesel injector(Conventional injector) SMD value decreases along the vertical axis when injector is in vertical position. Why is this? Are the spray dynamics are different?

Hirofumi Kizawa

Sorry if this is a disappointment to you. This is not an answer, rather a question. Did you use the same fluid whatever it might be between the two injectors when you measured SMD?

Does iodine value decrease or increase during bio-diesel oxidation?

Iodine value is the degree of unsaturation. If the bio-diesel is oxidized then unsaturations will increase, hence iodine value should increase. I require clarification regarding this.
