Fuel Injector Flow Testing

These are numbers from actual flow test results here at the injector rehab.

Fuel injector flow testing.

Turn the ignition switch to the on position. If they fail the reluctance test they are deemed irreparable. Touch the terminals one at a time of the harness connector with the test light. The following flow rates and numbers are not from any list.

Place a thin metal rod or screwdriver on one of the injectors and lean your ear close to listen for an audible clicking sound which indicates the fuel injector is functioning. Where the injectors are flow tested for 15 seconds at a specific fuel pressure 43 5 psi or 3 bar while the injector is held full open i e. Static fuel injector flow testing will only indicate if a fuel injector set flow the same and not how healthy the injector or fuel injector set is. Dynamic pulsed flow test.

Unplug the electrical connector from the fuel injector you want to test. Static fuel injector flow testing measures the amount of fuel that will flow through a fuel injector when that injector is fully open. The injector shop fuel injector flow test and reconditioning service includes the following processes and parts. Where the injectors are tested for 30 seconds at different duty cycles and the injectors are pulsed at varied pulse widths.

If you find one that isn t clicking there may be a problem with your injector or the electronic component that controls it. What is static fuel injector flow testing. Fuel injector flow testing includes the following. Automated electrical inspection of internal injector coil.

To test fuel injectors start by popping your car s hood while the engine is running. If you find a flow rate to be skewed it could be because of the flow pressure at which they were tested versus what the manufacture rated them. This duplicates real world conditions such as idling acceleration deceleration low speed and high speed. The amount of time the injector is energized and held open is.

This is done to prevent contamination of calibration fluid. It is done at a determined fuel pressure and over a specific period of time. The injectors are now installed in our computer controlled testing machine where they are tested for reluctance. One of the terminals should make the test light glow this is the injector power source coming from the computer.

All injectors are meticulously inspected for leaks both on the injector body and at the output nozzle. Fuel injector flow testing. Test each fuel injector in your vehicle the same way. Heated ultrasonic pre clean on the injector external body prior to placement in flow bench.
