Fuel Injectors

The last new American car sold in St. Paul with a carburetor rolled out of the MN dealership in 1990. Since then, all new vehicles here in St. Paul and nationally have had fuel injectors. In very simple terms, a fuel injector is a valve that squirts fuel into your engine. Your engine control computer tells the fuel injector how much gas to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute. Fuel injectors deliver fuel far more precisely than carburetors. That translates into better gas mileage and more power. Virtually all fuel injectors for gas engines are known as port fuel injectors because they deliver the fuel to a port just outside the cylinder. Port fuel injectors operate at about 40 to 80 pounds per square inch of pressure.

A few auto manufacturers have introduced gas direct injection systems on some engines recently. These systems inject the gas directly into the cylinders under very high pressure – hundreds of times the pressure of port injection systems. Although more complicated, direct injection technology promises greater power with improved fuel economy, so Minneapolis car owners can expect to see more of it in the future.

As you can see, the level of precision required of your fuel injectors is very high. They need to be operating properly in order for your car to run right.

High temperatures under your hood and variations in St. Paul gas quality cause fuel injectors to become fouled with wax, dirt, and carbon. Injectors can become partially clogged, preventing them from delivering the proper amount of fuel at the correct pressure. The design of each engine requires a specific spray pattern from the fuel injector that might be altered when the injector is dirty. When injectors are dirty, the fuel doesn’t burn as efficiently resulting in poor gas mileage and loss of power. So it is important to keep your foreign cars fuel injectors clean.

Skilled service technicians at Signal Garage Auto Care in St. Paul can perform a fuel system service for you. (Visit /contact-us-2/.) That is a fuel system service – not just fuel injector cleaning. That is because the fuel has a lot of ways to become dirty or contaminated between the St. Paul gas pump and your fuel injectors. A fuel system service starts with a fuel filter replacement. This filter cleans the gas as it leaves the tank. The various parts of the fuel intake system need to be cleaned from time to time to remove harmful gum, deposits and varnish. Finally, the fuel injectors are cleaned so that they operate properly and deliver the right amount of fuel at the right time.

Your caring Signal Garage Auto Care service advisor uses a process for cleaning your foreign cars fuel system that includes state-of-the-art cleaning chemicals as well as some old fashioned scrubbing. Proper maintenance of your fuel system means that you will enjoyed improved gas mileage, enjoy strong performance and prevent costly repairs down the road.
