Fuel Injection Basics for Tucson

All modern Tucson vehicles come with fuel injection systems, so it’s a topic Tucson drivers need to know something about. The mighty fuel injector is a valve that delivers the gas or diesel fuel to the right place, in the right amount at the right time—to be mixed with air and burned in the engine.

Over time, varnish can start to build up in the fuel injectors, effecting the pressure, pattern and timing of the fuel charge. The result is that the fuel doesn’t get burned as efficiently as it could. That robs performance and hurts fuel economy.

What about a good fuel filter? The fuel filter is component of the fuel system. Its job is to filter out the dirt and rust that collect in the fuel tank. If it’s clogged up, the dirt will bypass the filter and head upstream to the fuel injectors.

It’s important to replace the fuel filter when your manufacturer recommends it. That’s part of a comprehensive fuel system cleaning.

There are different kinds of fuel injection systems. Port fuel injection systems, the kind most gasoline engines have, operate at 60 pounds per square inch. The injectors for the new gas direct injection engines Tucson drivers are starting to see require 10 to 30 times as much pressure. And some diesel engines for passenger vehicles have injectors that operate at 30,000 pounds or more per square inch. There’s no room for dirt and gum in a precision part like that.
