Toyota 4Runner Fuel Injectors, Fuel Rails & Components

Have you ever wondered why vehicles with modern engines can run more than several hundreds of miles and last longer than old automobiles with carburetors? The answer is the fuel injection system, the computer-controlled system that operates by spraying fuel in the combustion chambers at regular intervals. How does it exactly work? When you push the accelerator pedal, the throttle valve opens therefore letting in more air. The engine control unit indicates this process and sends a signal to one of the fuel injectors to spay the required amount of fuel in the combustion chamber. The harder you push the pedal, the more air and fuel get in.

The fuel injection system of your vehicle not only provides your engine with fuel and air but also helps keep their optimal ratio inside the engine. Beyond the shadow of a doubt, the fuel injection system should be maintained on an ongoing basis. If any of the fuel injection system’s components fails, do your best to replace it as soon as possible.
