7 unusual facts about EFI


Mac OS X Tiger

However, with the release of 10.4.5, 10.4.6, and 10.4.7 the unofficially-modified versions continued to use the kernel from the 10.4.4 because later kernels have hardware locks and depend heavily on EFI.

Toyota L engine

Although the basic construction is similar to a modern gasoline injector, the EFI system in 2L-TE utilize considerably higher injection pressures.

Developed as a new version of 2L-T, the 2L-TE features a new development used in Diesel engines at that time, the EFI (Electronic Fuel Injection) system.

The EFI system meter fuel with great precision and succeeded in increasing the engine's efficiency.

Due to the EFI system, the 2L-TE develops significantly more torque than its predecessor.

Toyota R engine

It was also available as the 8R-D, dual SU 8R-B, EFI 8R-E, Californian-spec 8R-C and DOHC 8R-G.

Toyota VZ engine

The family introduced many changes for Toyota, including various EFI, ECU, and engine improvements from generation to generation.

Cheo Marquetti

He then joined a number of septetos, among them Septeto Cauto, led by Manuel 'Mozo' Borgella with whom he recorded in 1940 (including the song Efi Embemoro - the first Afro-Ñáñigo song to be recorded; Cheo Marquetti previously had recorded this tune in a duet setting with Bienvenido Granda in 1936, accompanied by Septeto Nacional de Ignacio Piñeiro).

EFI System partition

On Apple–Intel architecture Macintosh computers, the EFI partition is initially blank and not used for booting.

Ford EEC

With the Escort, the base engine was the same as all US Escorts, the 1.6L CVH, but featured unique intake and exhaust manifolds in addition to EFI.

This was non-sequential EFI, meaning 1/4 of the required fuel for each cylinder was injected into the intake manifold, near the intake valve for each cylinder firing.

EEC-IV first appeared on the 1983 1.6L EFI, 2.3L High Swirl Combustion (HSC), 2.3L EFI Turbo and 2.8L truck engines.

Live USB

Intel-based Macintosh computers have limitations when booting from USB devices – while the Extensible Firmware Interface (EFI) firmware can recognize and boot from USB drives, it can only do this in EFI mode.

O le Ao o le Malo

The second was held on 19 July 2012, in which Tufuga Efi was nominated by Prime Minister Tuilaepa Aiono Sailele Malielegaoi and seconded by Palusalue Fa’apo II, the leader of the opposition.

Proton Wira

However, in 2001 Proton replaced the Mitsubishi EFi module with Siemens VDO module that is claimed to cause slight power loss.

Rambler Rebel

The Bendix "Electrojector" electronic fuel injection (EFI) was to be optional on the 1957 Rambler Rebel with a flashy introduction at the Daytona Beach Road Course trials.

Royal Army Ordnance Corps

In 1964 the McLeod Reorganisation of Army Logistics resulted in the RAOC absorbing petroleum, rations and accommodation stores functions from the Royal Army Service Corps as well as the Army Fire Service, barrack services, sponsorship of NAAFI (EFI) and the management of staff clerks from the same Corps.

Unified Extensible Firmware Interface

These systems used EFI instead of Open Firmware, which had been used on its previous PowerPC-based systems.
