Fuel economy is the hot topic in the car industry today. There are many ways to improve your MPG, from using cruise control to braking less. While most of these driving-style changes offer slight efficiencies, they are likely to plateau if your vehicle is bogged down by sludge. Over time, your fuel system can accumulate particles, gum, and varnish that acts similarly to a blocked artery. With a buildup of gunk, less fuel can travel through the lines to the engine, reducing your fuel economy. A regular fuel system cleaning at Kennedy Transmissions can keep your fuel flowing.

Gas Tank to Engine: The Fuel System Explained

Have you ever wondered how the gas goes from the fuel tank just behind your rear doors to underneath the hood? There is a fuel line running the length of your car that, with the help of a pump, pushes fuel straight to the engine.

Before the fuel is ignited in the combustion chamber and that blast of energy is transferred into physical movement by a piston, it first goes through the fuel injectors. Most modern cars have replaced carburetors with an electronic fuel injector for each cylinder in the engine. The fuel injector’s job is to measure the precise amount of fuel needed to run the engine and send it off in a specific pattern that can vary by engine type and design. This is constantly working to propel your vehicle.

Your Car’s Cholesterol

Your vehicle can accumulate dirt and debris at each point in the fuel system. Eventually, it builds up to the point where the efficiency of transferring fuel to the engine is disrupted.

Starting with the fuel tank, dirt, rust, and sediment gather over the years. Car manufacturers have designed a fuel filter to clean the fuel when it leaves the tank. But just like any other filter, it needs to be replaced to continue to be functional; otherwise, the dirty gas will just continue through the system.  As it travels through the lines, deposits are left along the canal, blocking the optimal flow.

The biggest threat to fuel economy, however, occurs in dirty fuel injectors. As a precision instrument, gunk can affect the pressure and timing of fuel delivery. As debris builds up, this sophisticated part will not send gas to the engine in the correct patterns, causing inefficiency and possible transfer of gunk into the engine.

Pro Tip: Special additives help preserve an already clean fuel system; however, they cannot do major cleaning.
