“…Besides this, numerical simulation of the intake ports with different geometry was performed to study pollutant formation in DI diesel engines and it is concluded that the port configuration generating strong swirl flow resulted in enhanced soot oxidation and NOx formation [61]. Moreover, different combustion chamber geometries were considered to investigate the impact of the organized flow behavior on emissions [63][64][65][66][67]. For example, Wei et al [64] proposed a new swirl chamber combustion system of DI diesel engines with different swirl ratios (0.2-3.2) to develop the mixing quality and reduce exhaust emissions.…”

“…Recently, various types of research related to piston bowl shapes have been conducted to improve fuel consumption and reduce harmful pollutants of CI engine [61][62][63][64][65][66][67][68][69][70][71][72][73]. For instance, Jaichandar et al [63] studied the performance and emissions parameters in a biodiesel fueled DI diesel engine for different combustion chambers such as Toroidal Combustion Chamber (TCC), Hemispherical Combustion Chamber (HCC) and Shallow depth Combustion Chamber (SCC).…”

This study gives an overview of available literature on flow patterns such as swirl, tumble and squish in internal combustion engines and their impacts of turbulence enhancement, combustion efficiency and emission reduction. Characteristics of in-cylinder flows are summarized. Different design approaches to generate these flows such as directed ports, helical ports, valve shrouding and masking, modifying piston surface, flow blockages and vanes are described. How turbulence produced by swirl, tumble and squish flows are discussed. Effects of the organized flows on combustion parameters and exhaust emission are outlined. This review reveals that the recent investigations on the swirl, tumble and squish flows are generally related to improving in-cylinder turbulence. Thus, more experimental and numerical studies including the impacts of this organized flows on turbulence production, combustion behavior and pollutant formation inside the cylinder are needed.

“…The swirl is produced by providing helical threads, spiral threads with different pitches and orientations results improved performance and lesser emissions [2][3][4][5][6]. In addition to previous methods design of piston is also varied to provide swirl by providing tangential holes in the piston with varies dimensions and by varying d/D ratio which results in optimum configuration with minimum emissions [7][8]. Along with swirl turbulence also has some prominent role in proper fuel and air mixings which leads to proper combustion in turns improves performance of engine by reducing emissions.…”

This work provides a sequential approach to improve efficiency of Combustion Ignition engines which involves both performance and emissions by using the artificial neural network (ANN). In recent years continuous work is going on for improving the output and reducing the emissions especially for Combustion Ignition engines which are mostly used for transportation purposes. In view of the above, the experimental data of a four stroke Combustion Ignition engine is taken as reference. However, the experimental data is split into three categories as input data, target data and output data in neural networks. All these data are trained using neural network toolbar in MATLAB with ten hidden layers by which error deviation are calculated, in order to reduce error deviation between neural network and experimental values, design of inlet manifolds is varied and performance parameters along with emissions is calculated and compared with neural network values. The results showed minimum error over the emission and performance parameters of CI engines from the manifold designs and ANN model. These results provide a sequential approach to improve efficiency of Combustion Ignition engines with the help of neural networks.

The fluid motion in an internal combustion engine is a complex phenomenon and is cryptic especially in diesel engines. Air movement inside the cylinder can improve fuel-air mixing, and thus brings more power with better fuel efficiency; which mainly depends on, inlet and exhaust valve profile, manifold design and combustion chamber configuration. The aim of this paper is to provide a review on the techniques employed for improving the in-cylinder movement for better engine power and reduced emissions.
