The benefits of Flow Testing your fuel injectors to properly diagnose problems

Flow-testing of your fuel injectors allows you to compare the actual flow rate of each fuel injector to the original factory specifications. If the flow is within specifications, you know the injector should perform properly when it is reinstalled back in the engine. Flow-testing also is a good way to make sure the injectors are the right ones for the engine because one or more injectors may have been previously replaced by someone else.

A flow test on our patented ASNU Ultrasonic fuel injector cleaning equipment allows you to see each injector spray pattern. If you see a normal, cone-shaped mist, you know the injector is flowing properly. If you see streamers of un-vaporized liquid in the spray pattern, you know additional cleaning is needed or the injector needs to be replaced.

Injector cleaning will be an ongoing need as long as engines are equipped with fuel injectors. Even the new generation of direct injection gasoline engines that are now being built are vulnerable to fuel deposits. So be on the alert for the symptoms of dirty injectors and do not hesitate to have the injectors cleaned for preventive maintenance.
