ASNU Flow Testing & Cleaing Machine

ASNU Fuel Injector Flow Testing and Cleaning Machines

The ASNU is pretty much the standard for injector servicing. It can test and flow up to eight injectors at once for accurate comparisons. We've made quite a few improvements to it, (see below). Other improvements not shown are: an internal pulsation damper, re-plumbed for higher flow, and improved drive electronics. We took what we learned here and built or our custom machine, (see below).
Digital Pressure Gauge

Digital Pressure Gauges

Although the ASNU injector machine works well, we felt that the addition of a more accurate pressure gauge would give better consistency to the flow readings. This gauge is calibrated to 0.25%.

We also retain the dial type gauge to watch for fluctuations or any other abnormalities.
High Flow Pumps

High Flow Pumps

This is a magnetically coupled, stainless steel pump that can deliver over twice the flow as the stock ASNU pump. Does a great job for the big injectors.
ASNU Adapters

Test Adapters

We invest heavily in injector test adapters, this allows us to service most all types of top and side feed gas injectors. What we can't buy, we will get custom made. You can't get good results without the right tools for the job.
Calibration Fluid

Injector Calibration Fluid

We only use a certified test fluid to get good flow results. Each batch has the analysis results on the label. This fluid is very stable and will not harm the internal seals of the injector.

We don't use Heptane like some of other shops because it will give poor flow results.
Fluid Temperature Control

Calibration Fluid temperature control

We circulate the test fluid through our custom built temperature controller that heats or cools the fluid as needed. It also filters particles as small as 2 microns.
Specific Gravity Check

Checking the Specific Gravity of the fluid

We perform this test twice a week to verify the condition of the calibration fluid. When it falls out of spec, we change it.
