Gas Injectors

Gas injector spray patterns are extremely important and directly affect your engine's performance.  At First Diesel we have the correct equipment to test and analyze gas injectors. Shown here is our gas injector ultrasonic cleaning and flow testing machine.

 

Gas Injector Spray Pattern

These gas injectors are functioning incorrectly.  The fuel is leaking in globs from the injector nozzle valve (Note highlighted close-up).  Fuel entering the engine like this will not burn properly.  This will lead to erratic running, low power, bad gas mileage and high emissions.  It can also 'wash' the cylinders causing premature engine wear.

Ultrasonic Gas Injector Cleaning

The ultrasonic cleaning process. The injectors sit in an ultrasonic cleaning bath and are fired electronically as they are being cleaned.  This makes cleaning particularly effective as the injector valve is moving during the cleaning process.

Gas Injector Service 

This picture shows the SAME SET OF INJECTORS. After the cleaning the spray patterns are equal(Note highlighted close-up).  The spray is fine and misty with no fuel leakage.  As good as new!
Having your gas injectors ultrasonically cleaned by FDI ensures the injector spray pattern is correct.  At First Diesel,  often a full set  can be cleaned and tested for less than the replacement cost of one new gas injector.
