Combustion Modeling for Modern Direct Injection Diesel Engines
In order to comply with stringent pollutant emissions regulations, a detailed analysis of the engine combustion and emission is required. In this field, computational tools like CFD and engine cycle simulation play a fundamental role. Therefore, the goal of the present work is to simulate a high speed DI diesel engine and study the combustion and major diesel engine emissions with more deta...

متن کاملModification of piston bowl geometry and injection strategy, and investigation of EGR composition for a DME-burning direct injection engine
The amount of pollutant gases in the atmosphere has reached a critical state due to an increase in industrial development and the rapid growth of automobile industries that use fossil fuels. The combustion of fossil fuels produces harmful gases such as carbon dioxide, nitrogen monoxide (NO), soot, particulate matter (PM), etc. The use of Dimethyl Ether (DME) biofuel in diesel engines or other c...
متن کاملPrediction of Major Pollutants Emission in Direct-Injection Dual-Fuel Diesel And Natural-Gas Engines
The dual-fuel diesel engine (D.F.D.E) is a conventional diesel engine in which much of the energy released, hence power, comes from the combustion of gaseous fuel such as natural gas. The exhaust emission characteristics of the D.F.D.E needs further refinements, particularly in terms of reduction of Unburnt Hydrocarbons (U7HC) and Carbon Monoxide (CO) emission, because the concentration of thes...
متن کاملControl of variable geometry turbocharged diesel engines for reduced emissions
A multivariable control scheme is designed to minimize emission of nitrogen oxides NOx and generation of smoke in a Diesel engine equipped with a variable geometry tur bocharger VGT and an external exhaust gas recirculation system EGR Steady state optimization results in operat ing points where NOx emissions and smoke generation are highly coupled and require joint management by VGT and EGR act...
