PFI vs GDI Engines

Faced with demands for greater fuel economy, consumer engine manufacturers innovate continuously to balance efficiency with performance. Unsurprisingly, there's an intense focus on fuel injection systems to address these needs. And all that focus has led to one of the most prevalent engine hardware trends: the growing use of gasoline direct injection (GDI) technology over traditional port fuel injected (PFI) designs.
