Fuel Injection

An ideal fuel injection system can precisely provide exactly the right amount of fuel under all engine operating conditions. This typically means a precise air-fuel-ratio (lambda) control, which allows, for instance: easy engine operation even at low engine temperatures (cold start), good adaptation to a wide range of altitudes and ambient temperatures, exactly governed engine speed (including idle and redline speeds), good fuel efficiency, and the lowest achievable exhaust emissions (because it allows emissions control devices such as a three-way catalyst to function properly).

Here are a few signs there might be something wrong with your fuel injectors.

  • The Engine Misfires. Dirty fuel injectors may cause your vehicle’s engine to misfire.
  • Idling Gets Rough.
  • Your Gas Mileage Tanks.
  • The RPM Needle Starts to Dance.
  • Your Car Won’t Start.

It is recommended to get fuel injector cleaning done after every 60,000 to 90,000 miles. If you’ve noticed a sharp decline in your fuel economy, a lack of power in your car, or have experienced a sluggish feeling when you accelerate, it could mean you need a fuel injection cleaning service.

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 economy and loss of power. So it’s important for drivers to keep their fuel injectors clean.

The fuel system begins at the gas tank where the gasoline is stored. A system made up of fuel lines, fuel filters, fuel injectors and fuel pumps feed the gasoline into the engine where it is mixed with air and ignited by the spark plugs. If you don’t maintain a clean fuel system, some of the following things can happen:

  • The fuel pump can become clogged. This pump sends the gasoline to the engine so anything that hinders the flow or prevents this from happening properly, will cause engine problems. You may find it to be difficult to start your vehicle. You may also notice that the engine backfires, stalls or hesitates while you accelerate. The simplest way to avoid this type of problem is to periodically clean or replace the fuel filter.
  • The fuel lines can become cracked or clogged, again hindering the flow of gas going into the combustion chamber. Replace these damaged lines.
  • The fuel filter can become clogged. To make sure the flow of gasoline is not hindered, a fuel filter should be replaced at an interval between 20,000 to 40,000 miles.
  • The fuel injectors will need to be replaced. Fuel injectors will last anywhere from 50,000 to 100,000 miles. The amount of time it takes before one or more injectors fails depends on the type of gas you use and how often the fuel filters are changed.

Having a clean fuel system is vital to making sure your vehicle is operating properly. A fuel system that’s dirty will affect vehicle power, performance, fuel economy and drivability. It can also have a direct impact on some of the other engine systems in your vehicle. If you haven’t thought about cleaning your vehicle’s fuel system now it’s the time to do it.
