The rate of heat released during the combustion in Diesel engines is important for many reasons, including performance evaluation, pollutant formation, and control. Combustion in Diesel engines can be generally divided into three phases: pre-mixed, d

In this work, we present a method based on a zero-dimensional thermodynamic model for estimating the onset of the knocking phenomena in a flex-fuel engine using gasohol (gasoline blended with anhydrous ethanol) and blends of gasohol with hydrous etha

The combustion of by-products in boilers for steam generation plays an important role for heat recovery in industrial plants. However, the use of different fuels at the same time may cause flame imbalance, flame impingement and overheating at some po
