numerical investigation in the effect of number of nozzle hole on performance and emission in dual fuel engine
Authors
abstract
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 injection. the main object of this work is to investigate the effect of number of injector nozzle hole on the combustion and exhaust emission in a gas engine ignited with diesel fuel. we use one and three-dimensional simulation in parallel way in order to analyze the performance and combustion process of a dual fuel engine. the experimental results have also reported and compared with the simulated data.
