Car Care Tips

Fuel Injectors



The last new American cars sold in Cincinnati with a carburetor rolled out of the Ohio dealerships in 1990. Since then, all new vehicles here in Cincinnati 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 fuel economy and more power for Cincinnati car owners. 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 makers 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 efficiency, so Cincinnati car owners can expect to see more of it in the future.

As Cincinnati auto owners can see, the level of precision required of fuel injectors is very high. It's critical that they operate properly in order for your car to run right.

High temperatures under your hood and variations in Cincinnati 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 SUV fuel injectors clean.

Skilled service technicians at Tuffy Auto Service Center Cincinnati in Cincinnati can perform a fuel system service for you. (Visit http://www.tuffyfields-ertel.com/contact_us.)

A fuel system service at Tuffy Auto Service Center Cincinnati 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 for Tuffy Auto Service Center Cincinnati and deliver the right amount of fuel at the right time.
