What Is an EFI Fuel Pump and How Does It Function?
An EFI fuel pump is a type of electric fuel pump used in gasoline engines with Electronic Fuel Injection (EFI) systems. It delivers fuel from the tank to the engine at a high pressure, ensuring proper atomization for combustion.
According to the U.S. Department of Energy, fuel pumps in EFI systems maintain fuel delivery pressure between 30 to 80 psi, depending on the engine’s design and requirements.
The EFI fuel pump consists of an electric motor, a pump mechanism, and various components to regulate fuel flow. It operates by drawing fuel from the tank, pressurizing it, and sending it through fuel lines to the engine’s fuel injectors.
The Society of Automotive Engineers provides a similar definition, stating that EFI pumps are critical for maintaining proper fuel pressure and flow under various engine operating conditions, including acceleration and hill climbing.
Factors affecting EFI fuel pump function include fuel quality, ambient temperature, and electrical supply conditions. A clogged fuel filter can also hinder performance by restricting flow.
A 2021 report from MarketsandMarkets estimates that the global fuel pump market will reach $25 billion by 2026, indicating a growing demand for EFI systems, driven by increasing vehicle production and environmental regulations.
Ineffective EFI fuel pumps can lead to engine performance issues, reduced fuel efficiency, and increased emissions, impacting both vehicle operation and the environment negatively.
