The electronic fuel injection (EFI) system is a sophisticated technology designed to deliver fuel to the engine in an efficient and effective manner. This system replaces the need for a carburettor, which mixes air and fuel, and instead injects fuel directly into the engine manifold or cylinder using electronic controls. EFI has been used in the automotive industry for decades, but is not as common in smaller engines. The EFI system works by using solenoid valves to measure fuel supply with varying degrees of accuracy. This is more accurate than a carburettor, as the injectors are supplied with pressurized fuel through a high-pressure pump and fuel lines, while filters ensure that impurities and particles are kept away from the fine nozzles of the injectors.
This helps to improve atomization of the liquid fuel during formation of the gasoline engine mixture. In terms of acceleration enhancement, there are a couple more screens to consider (similar to the accelerator-pump circuit of a carburettor), quality settings at idle, and cold start functions (similar to those of a carburettor choke). Most modern EFI systems in the aftermarket will also create initial fuel and spark maps that will allow almost any engine to start and operate, providing you with a base from which to start tuning. The advantages of an EFI system include improved combustion, increased power, reduced fuel consumption, and meeting emission standards. It is an advanced fuel injection device adopted by gasoline engines without a carburettor that can help your vehicle run smoothly and with maximum performance while using the least amount of fuel.
