Exploring Your Car's Fuel System

When consumers visit the gas station, the most common thought on their minds is the price they're paying per gallon. Few people think about the process by which gasoline travels from the tank into the engine. We're going to address that process below.

If you're familiar with the workings of your vehicle's engine, you already know that fuel and air mix in each cylinder's combustion chamber. Within, the mixture is compressed as the valves close and a piston rises. A spark plug sits on top of the chamber and generates the spark needed to ignite the compressed mixture. That causes a small, contained explosion within the combustion chamber. The energy and the expansion of vapors pushes the piston downward, which aids in the propulsion of your car.

But, how does the gasoline make it into the combustion chamber in the first place? In this article, we'll quickly go through the entire fuel system. I'll describe each of the main components involved, so you'll have a better grasp regarding how the gas you pump into your car's tank ultimately propels you down the road.

The Gas That Flows Through The System

Despite what a lot of consumers think, no two fuels are exactly the same. To be sure, all of them have the same compounds. Moreover, they have similar additives and detergents (for preventing olefin deposits on your fuel injectors). But, each poses a slightly different level of volatility, which can loosely be defined as the ease of vaporization.

If fuel vaporizes (i.e. burns) easily, your engine can operate more efficiently. However, if it burns too easily, the mixture within the combustion chamber will be too lean. Similarly, if the gas does not burn easily enough, the mixture might be too rich. Given the high operating temperature of your engine, the level of volatility of your gas is important.

The Storage Facility

Your gas tank is where the fuel remains until it is needed by your engine. In most vehicles today, the tank is located toward the rear. Part of the reason is due to space limitations in the front. Most modern tanks are equipped with baffles that prevent splashing. If you're able to hear splashing, that usually means that they're broken.

The Network Of Hoses

Leading from your gas tank to your engine is a small network of hoses and lines. The former are made of rubber; the latter are made of steel. Eventually, they'll need to be replaced as a result of normal wear and tear. The rubber hoses must be replaced with the right type of hose to avoid deterioration. The steel lines must be replaced with steel.

Pumping The Gasoline

If you're driving a vehicle with a fuel injection system, it has a electric fuel pump. Cars with carburetors usually have mechanical pumps. Though it wasn't always the case, the fuel pump is normally built inside the gas tank. When you turn the key in the ignition, the pump receives an electrical signal. This signal generates the necessary pressure to push gasoline out of the tank and through the fuel lines.

The Fuel System's Crossing Guard

The fuel filter is arguably one of the most important components in the system. It helps to prevent dirt and debris from accessing - and clogging - your injectors. If the filter develops a clog, the pump is forced to work harder. That eventually causes it to burn itself out.

What may surprise many drivers is that their vehicles actually have two separate filters: one in the gas tank and the other in the line that leads to the injectors. It's the latter filter that needs to be periodically replaced.

Your vehicle's fuel system works seamlessly to keep your car on the road and operating efficiently. But, parts occasionally fail. Whether it's the tank, hoses, pump, or filter, make sure you're using high-quality OEM-certified replacements.
