2-Dimensional Investigations of In-Cyclinder Flow and Turbulence at Suction Stroke in Internal Combustion 4-Stroke Engines
Abstract
Studies and experiments conducted for the performance enhancement of internal combustion engines are of great importance. Today, challenges encountered in securing energy resources, the incremental costs and environmental factors constantly remind us that we should not ignore fuel economy in motor vehicles. Studies conducted in this framework focus on lower fuel consumption and less exhaust emissions while improving performance. Undoubtedly, combustion chamber designs and charge systems have a great effect on exhaust emissions and performance. For this reason, a suction stroke was modeled in two dimensions using the fluent software to better understand the charge systems in internal combustion engines. The design was based on 1600 cc Fiat engine measurements and engine geometry was defined. CFD (Computational Fluid Dynamics) software was used to investigate the valve opening and cylinder and combustion chamber air motion at 900, 3000, 5000 rev-1 RPM and the results were discussed in detail. CFD results will assist engine designers in understanding the effects of suction system and its components on various parameters.
