1994 Toyota Pickup Electronic Fuel Injection System (EFI)
1994 Toyota Pickup Electronic Fuel Injection System (EFI) – Electronic Fuel Injection system (EFI) is a development of the previous system, the carburetor. In the automotive world, the EFI system is a new system in the regulation of fuel and air ratio optimally. The components contained in the EFI system are generally the electronic components. EFI component consists of several kinds of sensors that take measurements in terms of, among others: the amount of inhaled air, engine load, cooling water temperature, intake air temperature, during acceleration or deceleration, and others.
The sensor will send the signal to the Electronic Computer Unit (ECU), and ECU ensures comparison of fuel and air (air-fuel ratio) to the cylinders to determine the volume of the fuel injection of the electrical work in accordance with the conditions and the load of the engine. The purpose of EFI (Electronic Fuel Injection) made was to cover the weaknesses of conventional fuel system using a carburetor. Where in the event of any inconsistency carburetor AFR (Air Fuel Ratio / Comparison of fuel with air) that is generated.
