Problem Statement
- Conventional fuel injection systems in gasoline engines struggle with incomplete fuel atomization and evaporation, particularly under cold start conditions.
- This results in poor fuel economy, increased emissions, and reduced transient response due to inadequate fuel vaporization.
- The proposed solution integrates an ultrasonic atomizer with port fuel injectors to improve fuel atomization and evaporation, addressing the shortcomings of existing systems.
Technology
- The proposed technology integrates an ultrasonic atomizer with conventional low-pressure port fuel injectors to enhance fuel atomization and evaporation, addressing issues like incomplete combustion and poor fuel economy, especially during cold starts.
- By mounting the ultrasonic atomizer in the intake manifold and adjusting its position dynamically, the system optimizes fuel vaporization and charge cooling, resulting in improved volumetric efficiency and lower emissions.
- Experimental testing demonstrates the system’s effectiveness in atomizing fuel efficiently, with most fuel droplets atomized within 15 milliseconds, offering better transient response and mixing compared to traditional port fuel injection systems.
