Port Fuel Injection (PFI) is a widely used technology in internal combustion engines that revolutionized the fuel delivery system, replacing traditional carburetors. PFI engines rely on the precise injection of fuel directly into the intake ports of each cylinder, resulting in improved fuel efficiency, enhanced power, and reduced emissions. This article provides an in-depth exploration … Read more

The two main fuel delivery techniques are port fuel injection (PFI) and gasoline direct injection (GDI). The primary difference between PFI and GDI engines is that PFI injects fuel into the intake port before it enters the combustion chamber, while GDI injects fuel directly into the combustion chamber for more precise control. This comprehensive comparison … Read more
