Effect of inlet air swirl on four stroke single cylinder diesel engine’s performance

Abstract

Optimizing airflow performance during intake valve process is the main purpose for this project. Analyses were done in CFD simulation and experimental using a test rig single cylinder 4 stroke direct injection diesel engine. This analysis also reported and compared with both analyses where experimental result can meet a nearly required targeted limit due to some realistic condition. Fabrication of intake valves also were made to do analysis on experimental based on the modify design. This being done after simulation analysis, modeling design was using to be fabricated and analyze the model on test rig machine to verify simulating result. This analysis could be used to increase thermal efficiency and maximizing usage of air fuel in combustion process, which reduce pollution to environment. Even though air flow have been optimized on its intake valve, but still intake system could be improve by considering other parts of engine such as intake manifold. Keywords—
