Experimental Investigations And CFD Analysis Of Combustion And Emission In CI Engines- A Review

Abstract

This work is a review of the analysis of experimental investigations and CFD to understand the combustion and emission characteristics of Compression Ignition (CI) engines. The objective of the review is to synthesize recent studies, analyse of results in CFD and experimental data, and provide recommendations for further research. The focus was made on turbulence and swirl flows, combustion modelling, spray and injection dynamics, and emission formulation in CI engines. It also involved a comprehensive literature review, and critical articles of relevant research articles. The main results suggest the significant impact of CFD simulations focusing on promoting air fuel mixing, combustion efficiency, and emission reduction in CI engines. On the other side, the disparities between the CFD predictions and the experimental data emphasize the need of the on-going work on the modifications of the models. The paper ends with propositions of the outstanding problems and efforts in multi-field approaches and more advanced CFD facilities to solve the issues of CI engines now and in the future.
