Numerical modeling of the effects of changing injection duration in double injection strategies in a DI diesel engine
Pollutant emissions from diesel engines are significantly affected by fuel injection strategies that could reduce NOx and Soot emissions. For the first time and in this study, numerical simulations were performed to consider the influences of changing the injection duration in each pulse of the double injection strategies on in-cylinder parameters and pollutant emissions. Results confirmed that...
متن کاملOptimal Earthmoving Fleet Size for Minimising Emissions and Cost
Traditionally, the earthmoving operations have been developed based on the minimum cost per production criterion. Nowadays, due to the negative impacts of the emissions on the environment, there is an increasing public awareness to reduce the emissions from the earthmoving operations. Different management strategies can be employed to reduce emissions, amongst other things, which can also resul...
متن کاملInvestigating the effect of construction management strategies on project greenhouse gas emissions using interactive simulation
The challenges posed by global climate change are motivating the investigation of strategies that can reduce the life cycle greenhouse gas (GHG) emissions of products and processes. While new construction materials and technologies have received significant attention, there has been a limited emphasis on understanding how construction processes can be best managed to control GHG emissions. Unex...
متن کاملA Simplified Coldstart Catalyst Thermal Model to Reduce Hydrocarbon Emissions
It is a well-known phenomenon that the bulk of hydrocarbon emissions emitted from internal combustion engines occurs during the coldstart period, thus necessitating new control strategies to reduce hydrocarbon emissions. A simplified thermal model of the catalytic converter during coldstart is developed, employing thermal dynamics, oxygen storage and static conversion curves. It is subsequently...
متن کاملEffects of Triple Injection Strategies on Performance and Pollutant Emissions of a DI Diesel Engine Using CFD Simulation
One of the main controlling parameters in diesel engine combustion is the fuel – air mixing process that has direct effects on engine performance and pollutant emissions, reviewing over previous literature showed that split injection strategies could satisfy this purpose very well. For the first time and in this paper, pilot and double injection strategies were combined and formed new triple in...
