Compression ignition diesel engines are the most promising source of power for many stationary and commercial vehicles. The performance of the diesel engine could be improved by the optimum design of the combustion chamber, induction system and exhaust system. In the case of diesel engines, airflow inside the engine cylinder has a considerable influence on the combustion and emission levels of the engine. In this research work, engine performance investigations are carried out by improving air swirl motion by applying guide vanes inside the intake manifold. The effect of guide vane on airflow inside the cylinder is studied by using 3D internal combustion engine simulation software under motored engine conditions with the help of ANSYS-CFX. A single-cylinder diesel engine is modelled to analyse the effect of the design and geometry of guide vane on airflow inside the cylinder. The guide vanes are designed to incorporate into intake pipe of the engine in different geometries. The number of guide vanes and angle of inclination is configured on the basis of simulation. The simulation result shows that the four guide vanes with 180° helix improve in-cylinder airflow characteristics like pressure, velocity and turbulent kinetic energy. The optimized guide vane intake manifold was designed and tested on the designed experimental test set-up. The experimental results show that the swirl ratio is improved from 0.8 for the base model to 1.35 for the modified manifold model. The engine also tested on a test bench with an basic engine intake system and modified intake manifold. The results show that the modified intake manifold reduces specific fuel consumption by 1% and CO and HC emission by 20%.
