“…NO x and HC emissions decreased with increasing combustion duration, while CO emission increased. Yousufuddin et al 21 studied the effect of combustion duration on a dual fuel hydrogen–ethanol CI engine. The engine test speed was 1500 rpm, while the amount of hydrogen was increased from 0 to 80% by volume.…”

In this research, we estimated and summarized the effects of combustion duration on the performance and emission characteristics of a spark-ignition engine using pure methanol and ethanol as fuels, which have not been previously presented. From the results, we demonstrated that an increase in combustion duration causes a decrease in peak firing temperature and peak firing pressure and an increase in trapped residual gas. The level of trapped residual gas when using ethanol as fuel is higher than that of methanol fuel. The indicated mean effective pressure (IMEP) and brake mean effective pressure (BMEP) increase to maximum values and then decrease with increasing combustion duration, while the brake specific fuel consumption (BSFC) reaches a minimum value and then increases. The optimal BSFC improved to 33.31% when the engine used ethanol fuel instead of methanol. The increase in combustion duration helps to reduce NO x and HC emissions, but an increase in CO emissions is observed.

“…The task of reducing pollution can only be accomplished by improving the engine design to achieve a complete and perfect combustion which is highly dependent on the uniformity of the air-fuel mixture. Improving engine design involves investigating the design of air inlet and outlet passages, injector nozzle, combustion chamber and fuel blends [1][2][3][4][5][6][7][8].…”

The current study aims to explore the combustion process in a diesel engine and investigate the behavior of pollutant formation at different time events and different locations in the combustion chamber. The time event for maximum rate of production of pollutant soot is also investigated. Further, time events are investigate at which almost all the amounts of pollutants soot and nitric oxide have been produced. The combustion simulation is performed on a 3D sector. Finite volume method is used for numerically solving the partial differential equations that govern the flow along with Transition SST turbulence model. Eddy dissipation model is used for turbulence chemistry interaction. For soot calculation, Moss-Brookes model is used which has less empiricism and theoretically provides superior accuracy.

The current study aims at simulating the in-cylinder combustion process in a diesel engine and investigating the engine performance and pollutant formation. The combustion simulation is performed on a 3D sector employing appropriate models for various physical and chemical processes contributing in the combustion phenomenon. The overall model includes Transition SST turbulence model, eddy dissipation model for turbulence chemistry interaction, Moss–Brookes model for soot calculation and Zeldovich mechanism for NO production other than the usual transport equations. The numerical solutions are based on the finite volume discretization of the governing partial differential equations. Engine performance has been studied in terms of pressure, temperature and heat release rate while the pollutants formation has been investigated in terms of soot and thermal NO production. The results show that the ignition delay is quite short and that the injection timing may be successfully employed to control the combustion behavior. The simulation results are quite consistent with the expected behavior of the target variables indicating that the CFD analysis can be successfully employed in the diesel engine design. The results validation may be acknowledged in view of the mesh independence test, literature comparison and justification of the models.
