Our Cleaning Process

Fuel Injector Cleaning and Flowing Process

At Boost Lab, we specialize in servicing a wide range of injectors, encompassing side feed, top feed, and direct injectors (GDI). Our expertise extends to gasoline injectors used in various vehicles and equipment, including cars, motorcycles, lawn mowers, and boats.

For diagnostic purposes, these injectors undergo a thorough testing process. We utilize either an ASNU or a Carbon Zapp flow bench, which are essential for accurate testing. During the disassembly process, components such as pintles, seals, and filter baskets are carefully removed using specialized tools. Our comprehensive testing procedure includes the following stages:

1. Leak Test: This test aims to identify any leaks in the pintle or body of the injector. Using the flow bench's variable pressure regulator, we adjust the system's pressure to match that of the specific vehicle, ensuring a precise leak detection.

2. Spray Pattern Test: This test evaluates the injector's fuel spray pattern. By utilizing the control panel on the flow bench, we can replicate the injector's performance as if it were installed in the vehicle. This approach allows for an exceptionally accurate assessment of the spray pattern.

3. Flow Test: The objective of this test is to measure the fuel flow from the injectors to the engine. It helps identify any discrepancies in flow rates. A high-quality flow bench can test multiple injectors simultaneously, facilitating more accurate comparisons.

4. Electronic Operation: This test examines the injector's performance under various operational conditions, checking its functionality and responsiveness.

Based on the results from these tests, we determine if the injectors require ultrasonic cleaning. This cleaning process efficiently removes crystallized particles and contaminants within just 10-20 minutes. It targets the internal parts of the injector, effectively unblocking them and restoring optimal fuel flow and injector functionality.

After undergoing ultrasonic cleaning, the injectors must be subjected to the same series of tests as before. This ensures that they function optimally post-cleaning. Once they pass these tests and are precisely adjusted and calibrated, we reassemble them with new components, including O-rings, pintle caps, filter baskets, and spacers, as required.

Why is it Necessary to Remove Injectors from the Vehicle for Servicing? When injectors remain attached to the vehicle, their performance cannot be accurately assessed. Therefore, they must be detached and tested on a flow bench.
