Analysis of Blended Fuel Properties and Cycle-To-Cycle Variation In A Diesel Engine With A Diethyl Ether Additive

In this study, the effect of adding small portions of a diethyl ether additive to biodiesel–diesel blended fuel (B30) was investigated. This study includes an evaluation of the fuel properties and a combustion analysis, specifically, an analysis of the cyclic variations in diesel engines. The amount...
