Electronic fuel injection. A fuel delivery system in which nozzles (injectors) spray fuel into the intake manifold or cylinders. This allows for precise fuel control and better fuel efficiency than a carburetor system.

Electronic Fuel Injection - A more sophisticated fuel system. A fine mist of fuel is sprayed into the combustion chamber for optimum ignition. The more ports, the finer the mist, the more accurate the system.

The system that delivers fuel to the combustion chamber of an engine. A fuel injector is an electronically controlled valve. It is supplied with pressurized fuel by the fuel pump and is capable of opening and closing many times per second. When the injector is energized, an electromagnet moves a plunger that opens the valve, allowing the pressurized fuel to squirt out through a tiny nozzle. The nozzle is designed to atomize the fuel - to make as fine a mist as possible so that it can burn easily. The amount of fuel supplied to the engine is determined by the amount of time the fuel injector stays open.

electronic fuel injection. See fuel injection/electronic fuel injection (EFI).

electronic fuel injection. A computer controlled system that injects fuel into engine cylinders to be mixed with air rather than having fuel and air flow through a carburetor as in older cars.

Electronic Fuel Injection. There are different types of fuel injection systems, but all have replaced the carburetor for introducing fuel into the engine with much more precise control and timing. This has many advantages in fuel economy terms, as well as providing better engine performance and reliability, with lower exhaust emissions.

Electronic Fuel Injection. Abbreviation for Electronic Fuel Injection. This type of system uses computer-controlled fuel injectors to spray fuel into the engine rather than mechanically controlled injectors or a carburetor. EFI comes in several varieties: "throttle body injection"

Electronic Fuel Injected

Electronic Fuel Injection. The fuel and air is electronically controlled and metered by the ECU to ensure the air / fuel mix is fed into the engine at the correct ratio, quantity, and at the right time.

Electronic Fuel Injection. Just about all new cars, trucks and SUVs use EFI. It is an electronically controlled fuel delivery system that delivers gasoline or diesel fuel into an engine.

Extensible Firmware Interface. In computers with the Intel Itanium processor, the interface between a computer's firmware, hardware, and the operating system. The Extensible Firmware Interface (EFI) defines a new partition style called GUID partition table (GPT). EFI serves the same purpose for Itanium-based computers as the BIOS found in x86-based computers. However, it has expanded capabilities that provide a consistent way to start any compatible operating system and an easy way to add EFI drivers for new bootable devices without the need to update the computer's firmware.
