Reformer Gas Application in Combustion Onset Control of HCCI Engine
Homogenous charge compression ignition (HCCI) combustion is spontaneous multi-site combustion of a nominally premixed air/fuel mixture that exhibits high rate of pressure rise and short combustion duration. To avoid excessive pressure rise rate and knocking, HCCI engines are fueled with highly diluted mixture using a combination of excess air and/or EGR. HCCI combustion is attractive due to ...
متن کاملEffects of Buffer Gas Composition on Autoignition of Dimethyl Ether
Experimental and numerical studies are conducted on the thermal, chemical and dilution effects of buffer gas composition on autoignition of dimethyl ether (DME). The buffer gases considered are nitrogen (N2), a mixture of N2 and argon (Ar) at a mole ratio of 50%/50% and a mixture of Ar and carbon dioxide (CO2) at a mole ratio of 61.2%/38.8%. Experiments are performed using a rapid compression m...

متن کاملApplication of Novel Gamma Alumina Nano Structure for Preparation of Dimethyl ether from Methanol
In this study, preparation of nano-sized gamma alumina with high specific surface area and high yield by thereaction between aluminum nitrate and sodium carbonate, without using any surfactant is reported. Bohemite (Aluminum oxyhydroxide) was prepared as a precursor by strict control of pH and reaction temperature. The gel produced was purified by washing fol...
متن کاملResearch and Assessment of Applying Dimethyl Ether “DME” Extracted from Natural Gas “Ng”, on Diesel Engine as a Clean Fuel (TECHNICAL NOTE)
Due to the shortage of liquid hydrocarbon fuels for compression ignition engines, researchers have constantly been looking for alternative fuels. Recently, dim ethyl ether (DME) with its interesting properties, such as high cetane number and low exhaust emission has drawn a lot of interst as a suitable fuel for diesel engines. The main objective of this study was to assess the potentials and fe...
