Numerical Investigation on the Effect of Injection Timing on Combustion and Emissions in a DI Diesel Engine at Low Temperature Combustion Condition
One promising way to achieve low temperature combustion regime is the use of a large amount of cooled EGR. In this paper, the effect of injection timing on low temperature combustion process and emissions were investigated via three dimensional computational fluid dynamics (CFD) procedures in a DI diesel engine using high EGR rates. The results show when increasing EGR from low levels to levels...

متن کاملNumerical Investigation in the Effect of Number of Nozzle Hole on Performance and Emission in Dual Fuel Engine
Air pollution is one of the major issues about the diesel engines in todays' world. It is a special concern in those areas that have difficulty meeting health-based outdoor air quality standards. Natural gas has low emission and resource abundance and also conventional compression ignition engine can be easily converted to a dual fuel mode to use natural gas as main fuel and diesel as pilot ...
متن کاملA Comparison of Numerical Results for an Optically Accessible HSDI Diesel Engine with Experimental Data
Comparisons between numerical results and experimental data for a homogeneous charge compression ignition (HCCI) engine with optical accessibility are being presented in this paper. The KIVA – 3V program, a general purpose combustion routine, is being enhanced by implementing the optimized Shell model for the ignition process, applying the extended Zeldovich formulation for nitrogen oxide forma...
متن کاملCFD Simulation of HSDI Engine Combustion Using VECTIS
As part of the VECTIS code validation programme, CFD simulations were conducted to investigate direct-inject (DI) diesel engine combustion with the newly implemented Ricardo Two-Zone Flamelet (RTZF) combustion model. A small HSDI research engine was chosen as subject. The simulation programme consisted of 6 cases forming a complete injection time swing. CFD simulation results were compared dire...
