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. |
