How a Fuel System Works

A vehicle’s fuel system is in charge of storing, controlling, and supplying the engine’s combustion chamber with fuel. A fuel system comprises of a fuel tank, fuel pump, fuel lines, fuel filters, and fuel injectors. The fuel is stored in the fuel tank until the fuel pump draws it out. From there, the fuel travels down the fuel lines, through the fuel filter, and then to the engine’s combustion chamber by means of the fuel injectors.

In this process, the fuel is mixed with air, atomized, and ultimately vaporized. Atomization and fuel pray patterns from the injectors play a large role in completing the combustion operation. Spray patters vary depending on the spacing, angle and number of holes in the injector tip. Atomization occurs tanks to injection pressure, which is regulated depending on the type of fuel system you have.

Return-Type Fuel Systems

A return-type fuel system is one that is designed with a fuel pressure regulator that diverges the fuel pressure based on the power of vacuum suction from the engine’s intake system. The purpose of the pressure variant is to ensure that the amount of fuel pressure and flow remains equal and consistent when the fuel reaches the injectors.

Returnless Fuel Systems

A returnless-type fuel system is one that is designed to use the powertrain control module (PCM) to regulate fuel delivery. A fuel pressure sensor mounted to the supply rail of the fuel injectors allows the powertrain control module to keep an eye on the fuel pressure. If the fuel pressure and flow starts to decrease as a result of increased engine speed or load, the powertrain control module will make up for the drop by increasing the injector duration and/or operating speed of the fuel pump.

Getting Rid of Gas Smell

Did you spill some gas all over your hands while filling up the lawn mower? Or perhaps the can spilled in the trunk while you were on your way home with it? Or maybe you had a little accident at the gas pump, and now your favorite jeans smell like the station itself? What about spilling gasoline on your driveway? All of these scenarios happen every single day to people just like you; but the difference is, you are about to learn how to get rid of gas odors for good!

What You Need

The materials you need to get rid of gas smells will depend on where the stain or spill occurs. Here are supplies that will work well to combat gasoline absorption and lingering odor:

  • Cat Litter
  • Baking Soda
  • White Vinegar
  • Dish Soap

Cement Floors

If you spill gasoline on a cement surface, like the garage floor, just grab the kitty litter. The clay granules of the litter will absorb the liquid and abate the smell. Simply cover the spill as soon as it occurs, then allow the litter to sit for 2 hours, and finish by sweeping it all up with a broom and dustpan. You may want to check with your city’s local laws pertaining to contaminated cat litter disposal.

Upholstery

If you get gas on upholstery, like your car seats or trunk bed, go for the baking soda and white vinegar. Combine equal parts water, vinegar, and baking soda, and then dip a cloth into the solution and delicately rub it into the spill.

Clothing

There is no bigger disappointment than getting gasoline on your clothes. But if this ever happens, just rely on some good old fashioned air, coupled with some white vinegar. Start by airing out the garment outside for 24 hours. If the scent is very strong, soak the garment in vinegar for an hour, and then hang dry outside for a full day. Once the garment does not smell like gasoline anymore, use a handheld vacuum on the affected area, and then clean it with a rag and mild dish soap. Finish by washing the garment alone in the washing machine on the hottest setting.
