Abstract

Purpose: This study aims to analyze the characteristics of fuel injection in the intake manifold of a four-stroke gasoline engine using numerical modeling and simulation methods.

Research Methodology: The study was conducted by modeling an injector using mathematical equations and varying the inlet speed.

Results: The simulation results revealed that as the inlet speed increased, the fluid injection points shifted faster. The wall area exhibited low speed due to the boundary layer effect, indicating poor fuel and air mixing in those areas.

Conclusions: The study demonstrates that varying inlet velocities significantly affect the speed and pressure distribution patterns within the intake manifold. Higher inlet velocities cause the spray point to shift more rapidly, enhancing fuel-air mixing in specific areas. The velocity vector distribution revealed vortex patterns around the spray points, further contributing to the mixing process.

Limitations: This study is limited by the specific conditions in the ANSYS FLUENT simulations, such as constant temperature and pressure, which may not represent real-world variations. Moreover, only a single injector model was examined, and future research could explore multiple injector configurations and their impacts under different operational conditions.

Contributions: This research enhances the understanding of how inlet velocity influences fuel-air mixing in gasoline engines. By using ANSYS FLUENT, the study offers valuable insights into velocity, pressure, and flow patterns in the intake manifold. These findings have implications for optimizing fuel injection systems in four-stroke gasoline engines, contributing to improved engine performance and efficiency.
