New Diesel Fuel Injectors & Cleaning / Repairs in Hamilton

About diesel fuel injectors:

Diesel vehicles deliver fuel to the engine via injectors, which send diesel fuel directly into each cylinder. For optimal engine performance, each injector must be able to withstand the temperature and pressure inside the cylinder and still deliver the diesel fuel in a fine mist.

The state of the diesel fuel injectors can affect engine performance and fuel economy. For this reason, it is important that each diesel injector is kept in good condition. When a diesel fuel injector fails or becomes clogged, it will need to be replaced or repaired in order to restore diesel engine performance. 

Older diesel fuel injectors are mechanical in operation whereas modern diesel car, utes and vans use electronically controlled diesel fuel injectors and diesel fuel injector pumps. The latest diesel car, utes and van engines use common rail diesel fuel injection which is fully computer controlled.  Diagnosis on all late model computer / electronically controlled diesel  diesel car, utes and vans requires the latest scan tool technology.

How do diesel fuel injectors work?

 

Causes of diesel fuel injector damage:

Diesel fuel Injector leaking – If a diesel fuel injector develops a leak in the combustion chamber, it can leak a small amount of diesel fuel into its corresponding cylinder making that cylinder run rich. This can cause reduced engine power, increase fuel consumption (due to excess fuel leaking out) and increase exhaust emissions.

Blocked injector – Fuel system debris or rust can block the fuel injector’s nozzle, reducing the amount of fuel that can enter the engine. This can make the diesel engine run lean or if no diesel fuel is injected, misfire or have one or more cylinders down. 

Excess fuel injection – In some cases, a faulty fuel injector can become stuck open, causing too much fuel to enter the engine. This results in higher fuel consumption as well as black smoke coming from your exhaust. 

Petrol in diesel tank – If you accidentally put petrol in a diesel vehicle, the fuel system and fuel injectors can become damaged.

 

Symptoms of diesel fuel injector problems

 Common symptoms of a faulty diesel fuel injector include:

  • Increased diesel fuel use
  • Loss of diesel engine power
  • Engine not running on all cylinders (requires an Idle Cylinder Balance Test)
  • Rough idling and poor diesel engine performance
  • The diesel engine does not reach full RPM expected
