In very simple terms, a fuel injector is a valve that squirts fuel into your SUV engine. Your engine control computer tells the fuel injector how much fuel to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute in every single fuel-injected car driving down Joliet, Rockdale, and Ingalls Park expressways.

Most fuel injectors for gas engines are known in the Joliet automotive community as port fuel injectors because they deliver the fuel to a port just outside the cylinder. The fuel pump provides pressure needed to squirt the right amount of fuel into the engine.

A few auto makers have recently introduced gas direct injection systemson some engines. They are now available at some Joliet dealerships. These systems inject the gas directly into the cylinders under very high pressure – many times the pressure of port injection systems.

Although more complicated, direct injection technology promises greater power with improved MPG for gas-poor Crest Hill, Rockdale, and Joliet drivers. Illinois motorists can expect to see more of it in the future.

High temperatures under your SUV hood and variations in Joliet gas quality cause fuel injectors to be fouled with wax, dirt, water, additives and carbon. Injectors can become partially clogged, preventing them from delivering the proper amount of fuel at the correct pressure.

When injectors are dirty, the fuel doesn’t burn as efficiently resulting in poor fuel efficiency and loss of power. So it’s essential for Joliet drivers keep their fuel injectors clean.

Your tech ar Tuffy Joliet can perform a fuel system service for you in which the fuel injectors are cleaned so that they operate properly and deliver the right amount of fuel at the right time.

Proper maintenance of your SUV fuel system means that you will spend less on gas, enjoy strong performance and prevent expensive Joliet repair bills down the road.
