Characteristic of Blended Fuel Properties and Engine Cycle To-Cycle Variations with Butanol Additive

Biodiesel fuel characteristics are one of the most important parameters that limited their application in diesel engines. Though biodiesel-diesel blended fuel can replace diesel satisfactorily at low blending ratios up to 20%, problems related to fuel property persist at high blending ratio. Hence,...
