Prior to the development of today's off-the-vehicle fuel injector bench testing and cleaning equipment, there were really only three methods employed to remedy fuel injectors problems.
A) Pour fuel injector cleaner in the gas tank.
B) Leave the fuel injectors on-the-vehicle and hook up cleaning equipment to the fuel system.
C) Throw away the old fuel injectors, and buy and install new ones.
Let's look at each of the three and evaluate the merits and disadvantages of each.
BOTTLED INJECTOR CLEANER
Pour fuel injector cleaner in the gas tank.
a) least complicated
b) least costly for the service and product
c) anyone can do it
a) Inability to accurately determine the results. A visual inspection of spray pattern is not available, nor is it possible to quantitatively measure injector flow rates. The injectors cannot be observed for mechanical or pintle leaks. The driver was left to his/her own evaluation of any improvement, by a seat of the pants feel, or possibly measuring mpg improvements.
ON THE VEHICLE SERVICING
a) Better cleaning success rate as cleaning chemical is not mixed or diluted with fuel.
b) The service could be accomplished without removal of vehicle components....injectors/fuel rail/etc.
c) Generally, the service could be performed within several hours.
a) Potential damage to injector parts, the fuel system, engine, or exhaust system from the "cleaning" chemical.
b) Inability to accurately determine the results, via visual inspection and actual measurement of spray patterns, and fuel flow results, potentially leading to other "trial and error" servicing, or "diagnosing", or costs. Again, the driver was let to his/her own evaluation of any improvement, by "feel" of the vehicle.
c) Injector parts could not be inspected or replaced.
BUY NEW INJECTORS .
a) Greater success with new parts.
a) High cost
b) If all injectors are not replaced, the replaced injector(s) may vary in performance from the non-replaced injectors, which continues to prevent optimum engine and emission performance.
c) Vehicle owner, or mechanic, may overlook other injectors which may require service or replacement.
STATE OF THE ART...ULTRASONIC FUEL INJECTOR TESTING AND CLEANING.
As fuel prices around the world continued to climb higher and higher, while at the same time, world populations increased, and the number of petrol fueled engines increased, and also occuring were stricter requirements to lower vehicle exhaust emissions, it was apparent that new fuel injector cleaning and servicing techniques needed to be developed.
The state of the art answer to fuel injector testing and cleaning came from Austrailia. The ASNU corporation, using the latest technology, developed and perfected a fuel injector flow bench tester/cleaner that would repeatedly and reliable test petrol fuel injectors.
The "ASNU-01" petrol flow bench machine, and the associated injector test methodology, now allows petrol fuel injectors to be visually inspected for spray pattern, quantitatively measured for flow volume, leak tested, electrically checked, visually inspected for mechanical damage, and ultrasonically cleaned, while providing both pre-testing and post-testing results.
1) The Merits
a) Each injector can now be visually inspected and compared to all other injectors in the set, for uniformity of spray pattern and atomization of fuel.
b) Each injector can now be visually inspected for internal rust within the filter bore, rust in the injector filter,. missing or damaged injector parts, which may also be valuable in diagnostics of other fuel and engine component problems.
c) Each injector can now be quantitatively tested for proper cc flow volume across a wide range of simulated engine operating modes, and fuel pressures, for conformance to specifictions, and injector flow volumes can be compared, within sets of injectors.
d) Each injector can now be pressurized and tested for leaking at the pintle/pintle seat, as well as leaks at mechanical joints.
e) Each injector can now be ultrasonically cleaned of "baked-on" fuel additives, such that injectors, in most cases, can be restored to as-new condition.
f) Because the bench testing and cleaning is off the vehicle, there is no potential for damage to the engine, the exhaust system, or other fuel system components.
g) Off the vehicle bench testing allows for injectors to be cleaned, or replaced if necessary, whereas other cleaning methods will not detect dirty injectors or injector failure, thus requiring the fueling ECU to "attempt" to balance fuel delivery via exhaust emission readings, received from the O2 sensor.
h) Before and after ultrasonic cleaning test reports can be observed and compared. This being a very important point, as it provides definitive information to the vehicle's owner, or mechanic, as to servicing results, and the need for further engine diagnostics...
i) Injector components (pintle caps, filters, o-rings, spacers, bushings and hoses) can be replaced
j) While off the vehicle, the injectors can be ohm tested for proper resistance values. .
k) The ultrasonic cleaning method and the cleaning solution is environmentally friendly, and as servicing is "off-the-vehicle", there is no chance of harm to other engine components..
l) The ASNU cleaning method is substantially less costly than replacing "dirty" injectors
a) Because bench testing requires removal of the injectors, the service is best performed during routine maintenance of the engine, during an engine overhaul, or whenever injectors are suspect for poor engine performance, or poor vehicle fuel economy, or emission problems..
b) In the short term, cleaning cost is higher than "bottled" cleaning, about on par with "on-the-vehicle" fuel system cleaning, but long term cost/benefit analysis, for comprehensive testing and cleaning, exceeds any short term cleaning method.
